How to Fix a Furnace Ignitor


Is your furnace ignitor not working? Do you even know what a furnace ignitor is? Luckily, we can help you. In this blog post, we’ll be discussing how you can troubleshoot your furnace ignitor and what to do when you can not fix it. We will also be discussing what a furnace ignitor is, how it works, and what to do when your furnace ignitor isn’t the problem. We hope you find this informative and that it helps you navigate the murky waters of dealing with a broken furnace ignitor. If you have any additional questions, leave a comment below and we will try our best to answer them.  

Furnace Ignitor

How Does It Work?

A furnace ignitor, to put it simply, is used to heat the gas in a furnace and cause combustion. This allows a furnace to produce enough heat to properly warm a home. The average temperature a furnace ignitor operates around is 1,200 Fahrenheit or around 649 Celsius. If a furnace ignitor isn’t hot enough, then it won’t be able to start the chain reaction which is required to generate heat inside of a furnace. If your furnace ignitor isn’t working then you won’t be able to heat your home. 

Ways to Fix Your Furnace Ignitor

  • Make Sure It is Actually Your Furnace Ignitor Causing Problems

While you may believe your furnace ignitor is causing issues it’s important to check other things in your furnace first. For example, when was the last time you replaced your air filter? If it has been a while, replace it and see if that is the issue instead of your furnace ignitor. As mentioned in our article “How to Take Care of Your Furnace,” you need to replace your filter regularly. The thicker the filter is, the longer it is going to last. You should also check your thermostat and make sure it is working properly. 

Of course, there is an easy way to tell your furnace ignitor has gone out. If you open your furnace panel and see that your furnace ignitor is cracked, chipped, shattered, etc. it has gone bad. You can also test your furnace ignitor with a multimeter. A multimeter measures the voltage, current, and resistance. After measuring your furnace ignitor, if it stays on zero then it has gone bad. Remove your furnace ignitor before testing it and turn your furnace off. 

  • Check Your Breaker

Your furnace ignitor may not be working because of a tripped breaker. Your breaker might have been overloaded and caused your furnace to switch off. You should check to make sure that your breaker wasn’t tripped. There might be a red light next to the breaker if it was tripped. Flip the breaker completely off and then flip it on again. You can try this a few times and see if it helps. If it doesn’t, you can narrow the issue down even further and rule your breaker out. 

  • Reset your Furnace Ignitor

To reset your furnace ignitor, the first thing you should do is to make sure your furnace is on. After checking to make sure your furnace is on, turn it off along with its gas supply. You should wait at least ten minutes to make sure that it is no longer running. Once you have made sure that your furnace is no longer running and waited the appropriate amount of time, turn your furnace back on. You can do this by finding the ignition button on your furnace and pressing it. Wait a bit for your furnace to power back on and see if resetting your furnace ignitor solves your issue. 

What to Do When You Can’t Fix It

  • Replace It

The average lifespan of a furnace ignitor is four to seven years. If your furnace ignitor has reached its lifespan, replace it. If it hasn’t however, the average furnace ignitor costs around $30 to $50 if you replace it yourself. If you have an HVAC technician replace it, you’ll have to count labor in the cost. You can replace your furnace ignitor yourself easily, but first, make sure your furnace is turned off. We can not stress this enough. Always, always turn off your furnace before attempting to work on it. Another thing to keep in mind is that your furnace ignitor is fragile. Handle it carefully when replacing your old one. Replacing your furnace ignitor can sometimes be the only thing you can do. Thankfully, it’s not as expensive as replacing your whole furnace. 

  • Call an HVAC Technician

If replacing your furnace ignitor doesn’t work or you don’t feel comfortable doing it yourself, we recommend you call an HVAC technician. An HVAC technician will not only replace your furnace ignitor but make sure that it’s the issue in the first place. As mentioned in the “Ways to Fix Your Furnace Ignitor” section, while a furnace ignitor might seem like the issue, it isn’t always.

What Causes a Furnace to Stop Working?


Are you wondering why your furnace just suddenly stopped working? Did it just happen abruptly with no warning? If that’s the case, then maybe we can help point you in the right direction. In this month’s blog post, we’ll be talking about the signs of a broken furnace, reasons why a furnace may have stopped working, and what to do next if you can’t fix it. If this blog post helps you out, feel free to leave a comment below! You can also leave a comment if you have any additional questions. Now, let’s get into the blog post.

Signs of a Broken Furnace

There are plenty of signs that your furnace isn’t working with the most obvious one being that it won’t turn on. However, that is not always the case. There are signs of a broken furnace that are not always so black and white. In this section, we’ll be covering five signs of a broken furnace. 

  • Excessive Dust Buildup

If you notice excessive dust buildup in your home then your furnace may not be working properly. Excessive dust buildup can be caused by your furnace not being able to circulate air. You should check your furnace’s filter and see if that is the cause of your problem. If you haven’t replaced your furnace in a while, it is likely that a clogged filter is the reason why your filter is not working. 

  • No Hot Air

Another sign of a broken furnace is when there is no hot air blowing out of it. There might also be cold air blowing out of your furnace. You should first check on your filter and see if it is dirty. If it is, replace it and see if there is a change. If there is a change, the issue might not have been with your furnace but specifically with your filter. A clogged filter prevents proper airflow. A way to make sure you don’t have a clogged filter is to replace your filter frequently as recommended. Depending on the size of your filter depends on how often you should replace it. A rule of thumb though is the thicker the filter is, the longer you can go without replacing it. 

  • Strange Odors Coming from Furnace

If you smell something such as rotten eggs or burning dust from your furnace, check it out right away. If you smell rotten eggs in your house for any reason at all, you likely have a gas leak.  Evacuate your house and call the fire department. If you smell burning dust from your furnace, check your furnace filter. If you haven’t used your furnace in a while then it is likely just the cause of dust buildup from lack of use. The odor should clear out after a while and not cause any damage to you or your furnace in the process. 

  • Carbon Monoxide Poisoning

Carbon monoxide poisoning is a silent killer that can happen because of a gas leak. In oil and gas furnaces, carbon monoxide is produced. The carbon monoxide is usually contained inside your furnace, but sometimes a leak happens. Your furnace will not be working properly if there is a gas leak and you and your family will be at risk. Some signs of carbon monoxide poisoning are dizziness, headaches, vomiting, confusion, and shortness of breath. If you suspect you have carbon monoxide poisoning you should call poison control immediately and evacuate your house. Carbon monoxide is an odorless gas and cannot be detected unless you have a carbon monoxide detector. A carbon monoxide detector measures the amount of carbon monoxide in the air and warns you if it gets too high.

Explanations Why Your Furnace Stopped Working

There are different reasons why your furnace may have stopped working. If you can narrow them down, you can figure out how to fix your furnace and get it back to optimal condition again. 

  • Old Age

Your furnace may just have stopped working due to old age. A furnace usually lasts between 15-20 years depending on the amount of care it was given and the model. Old age comes for all furnaces eventually. You can increase your furnace’s lifespan by taking care of it. In our blog post, “How to Take Care of Your Furnace,” we highlight some tips and tricks for taking care of your furnace. 

Home circuit breaker
  • Your Home Circuit Breaker Needs to Be Reset

Your home circuit breaker may be the issue with your furnace. All furnaces, even gas furnaces, use electricity. If your furnace isn’t working, try resetting your home circuit breaker. To safely reset your home circuit breaker, turn off all your lights and unplug everything. Then reset the main breaker on your circuit breaker by turning it off. Wait a little bit and turn it on again and see if that helps. If you want to specifically only reset the circuit breaker used for your appliances, then you need to reset the double-pole breakers. You can read more about resetting your home circuit here.

  • Your Furnace is Clogged

As mentioned in the above section regarding a furnace that doesn’t produce heat, your furnace might be clogged because of your filter. If your filter hasn’t been changed in a while, particles will get stuck in it and prevent air from passing through. The more buildup in your furnace’s filter, the worse it is going to be able to do its job. In order for your furnace to keep working, you have to change your filter as recommended. 

Furnace Filter
  • Your Thermostat Malfunctioned

The reason your furnace may not be working is because of your thermostat. Some issues that are correlated with furnaces not working and thermostat malfunctioning are furnaces producing too much heat and not enough heat. A few ways you can figure out if your thermostat is the issue is to replace the battery if it is electric. If you notice that your furnace is working right after you replace your thermostat’s battery, the issue was with your thermostat and not your furnace. 

What You Can Do

If you have tried everything and still can’t figure out why your furnace isn’t working, you can call an HVAC company and talk to them about the issue. Sometimes your furnace can’t be fixed with just a simple solution. You should talk to the HVAC technician and tell them what you have already tried doing. This can help them to narrow down the issue. We do not recommend you try to  repair your furnace yourself unless you are an HVAC technician. A lot of HVAC companies will not want to touch furnaces that have been clearly altered by homeowners or other companies. HVAC companies can potentially be held responsible if anything goes wrong after a homeowner or another company tries to fix a furnace. Save yourself the heartache. Make sure you research an HVAC company before letting them into your home and leave more complicated fixes to the professionals. 


We hope we were able to help and answer your question about why a furnace may not be working. Sometimes a broken furnace can be easily solved by routine maintenance and just resetting a thing or two. Sometimes it can’t be, however, it’s good to know what to do in the future if a problem arises again.

How to Take Care of Your Furnace


Knowing how to take care of your furnace is crucial to its health and your wallet. Being able to take care of your furnace can save you from paying an expensive bill and worrying about not being able to heat in your house. In the last blog post, we addressed how to take care of your air conditioner. We talked about why you should take care of your air conditioner, tips and tricks on how to take care of it, and what to do when things go wrong regarding it. In this month’s blog post, we will be doing exactly the same except instead of talking about air conditioners, we will be talking about furnaces instead. It’s just as important to know how to take care of your furnace as it is to know how to take care of your air conditioner. You’ll be having your furnace for a long time after all. Furnaces can last for twenty years before they have to be replaced if they are taken care of properly. It costs more to replace your furnace than it costs to take care of it. We hope that we can direct you in the right direction when it comes to taking care of your furnace and it will be with you for many years to come. 

Gas Furnace

Why Take Care of It?

There are several reasons why you should take care of your furnace. When your furnace doesn’t work properly, you will eventually notice and you won’t be able to ignore it. It may start as a minor issue, such as a weird noise occasionally, but as time goes on, it will get worse. You should also take care of your furnace so it works to its best ability and you can avoid future problems. A furnace that works well will be able to heat your home better and will be able to regulate temperatures so they don’t vary from room to room. Not only should you take care of your furnace to make sure it works properly, but you should do it because taking care of it will save you money. As mentioned in the above paragraph, taking care of your furnace will save you more money as time goes on. It costs more money to completely replace your furnace than it costs for it to be serviced. If you take care of your furnace, you can extend its life. Taking care of your furnace is a good idea for a multitude of reasons. While only a few of them were highlighted in this paragraph, we hope you found them informative. Taking care of your furnace might be tedious and tiresome, but it is worth it in the long run. 

Tips and Tricks

It can be hard to take care of your furnace when you don’t know how to. In this section, we will be covering some tips and tricks you can do to take care of your furnace. 

  • Keep All Flammable Objects Away from Your Furnace

It’s important to keep all flammable objects away from your furnace. Flammable objects near your furnace are a fire hazard. While some may argue that keeping flammable objects away from your furnace may not technically be a tip for taking care of your furnace, if your house burns down then your furnace will go along with it. A good rule of thumb is to keep flammable objects at least five feet away from your furnace. If possible, try and keep flammable objects outside of the room where your furnace is housed. It will give you more peace of mind. 

  • Replace the Filter

You need to replace your filter frequently in your furnace. The thicker the filter is, the longer it’s going to last. For example, a 2-inch filter needs to be replaced every three months while a 4-inch filter needs to be replaced every six months. You can check to see how thick your filter is by turning off your furnace and locating where it is on your furnace. It should say it clearly. Once you find your filter and determine its size, you can order another filter to replace your old one. The average furnace filter costs around $10 to $30 according to Home Advisor. The cost can depend on the thickness, quality, and brand of the air filter. After your new filter arrives, you can replace the old one and you are all done! You can cross off replacing your furnace filter off your to-do list and feel good about maintaining your furnace. 

  • Clean the Vents

Your ductwork, a system of vents, is used to transport hot air from your furnace to different rooms in your home. If there is a blockage in them then it can prevent the air from reaching its destination. As addressed in our blog post, “How to Clean Your Ductwork,” you’ll need a few tools such as an HVAC brush, high powered air compressor, and a high powered vacuum. You’ll need to turn off your furnace and air conditioner, open up a ductwork entrance, seal off the rest of your vents, and use the tools mentioned to clean your ductwork before closing it up. You can read more about it in our “How to Clean Your Ductwork” post that we mentioned. Keeping your vents clean will help your furnace to transport air easier and you will notice the difference as your home significantly warms up faster. 

  • Check the Thermostat

Checking to make sure your thermostat is displaying the right temperature is important. If your thermostat is displaying the wrong temperature, it can indicate problems with your HVAC system as a whole. One simple thing you can do to test your thermostat is to adjust your thermostat’s temperature five degrees higher or lower than what you usually have it on. If your furnace doesn’t turn on, that means there is an issue with it. If you have a digital thermostat, try replacing the batteries and see if that changes anything. If you are still having problems and that doesn’t help, try switching between two options on your thermostat: heat and cool. Depending on what you would like, switch the option, and see if that helps. The reason why you want to check your thermostat is because, without it, your furnace will not be able to work properly. You won’t be able to control how hot or cold it is in your house without it.  

These tips and tricks should help to prolong your furnace’s life and help it run to its best ability. We hope this helped you and gave you an idea of how to take care of your furnace. These simple tips and tricks can help you take care of your furnace tremendously if you follow them.

What to Do When Things Go Wrong

Sadly, things do sometimes go wrong with your furnace. A weird noise or smell may come from your furnace or it may stop working altogether. When that happens, you should call an HVAC technician. Try to remember if you changed anything right before your furnace stopped functioning properly as this will help the HVAC technician. Describe in detail how your furnace is acting up. Even the smallest details will help the HVAC technician to get a picture of what the problem is and help to come up with a timely solution. The HVAC technician will come out to your house and examine your furnace. During this time, tell them if you have tried to troubleshoot your furnace if you haven’t told them already. The HVAC technician will be able to better understand if the issue can be solved with a basic fix or not. An important thing to also include is the model of your furnace and how old it is. Also, tell the HVAC technician what type of furnace it is. Is it a gas furnace? Is it an electric furnace? The more specific you are, the faster your furnace will be fixed. You can not control when your furnace breaks, but you can control how you react to it breaking. Educating yourself on what to do when things go wrong with your furnace can help significantly and the HVAC technician you call will appreciate it.  


Learning how to take care of your furnace is an essential skill that will help you keep your HVAC system running. You should always replace the filter, keep flammable objects away from it, and keep the vents clean. When your furnace fails, you should contact an HVAC technician and provide them with as much information about your furnace as possible. We hope this blog post taught you how to take care of your furnace. If you have any more questions, ask them in the comments below.

How to Take Care of Your Air Conditioner


Taking care of your air conditioner can be as easy as breathing if you know how to do it. Basic air conditioner maintenance can save you thousands of dollars down the line and several costly phone calls to your local HVAC company. In this blog post, we will outline some things that you can do to prolong the life of your air conditioner. If you take proper care of your air conditioner, it will last longer and perform better. We hope this blog post will help you to better take care of your air conditioner and save you money in the future. 

Why Take Care of It?

You might be asking yourself “why should I take care of my air conditioner?” We recommend you take care of your air conditioner for several reasons including the ones mentioned in the paragraph below. Some other reasons why you should take care of your air conditioner is because it will not run properly unless you do so. Minor issues when left unchecked on an air conditioner can build up to become bigger, costly issues. Your air conditioner’s health depends on proper care and while an air conditioner can last up to twenty years, it won’t unless you take care of it. Your air conditioner’s care should not be left up entirely to an HVAC technician. There are several things you can do yourself that can keep your air conditioner healthy and working to its best ability. In the paragraph below, we will be highlighting some tips and tricks to keep your air conditioner healthy. 

Outside unit air conditioner

Tips and Tricks

  • Replace Your Filter

One of the biggest tips we can give you is to replace the filter of your air conditioner. We recommend you change your filter once a month unless it is a 6-inch pleated filter then you should change your filter every six months. You should also make sure that you have the proper replacement filter before attempting to change the filter in your air conditioner. An important thing to note is the size of the filter. 

To change your filter, first, turn your air conditioner off. Then, locate on your internal air conditioner unit where it says “filter.” It will be a panel and your air conditioner should say it clearly. There should be two screws on both ends of the panel that can be loosened.  After loosening the panel, gently pull your old filter out. Before inserting your new filter, look for an arrow that should be located on it that says “airflow.” For proper airflow, you want that arrow pointing up so your air conditioner will work right. It may take a few tries to get the filter in. Once you are done inserting the filter, carefully slide the panel back into place and tighten the screws up. Now, you are all done! 

  • Clear Debris Around Your Outside Unit

Another easy thing you can do to keep your air conditioner working properly is to clean the debris around it. You should clear away branches and leaves that are around your outside unit. If you also have any bushes or shrubs planted near your outside unit, you should trim them. A good rule of thumb is to keep any debris away from your air conditioner by three feet. This will help your air conditioner to be able to circulate air coming in and out of it to its best ability. 

  • Clean the Fins

The outside of your air conditioner has fins that are used to help improve the airflow of your unit. If these fins are blocked, that reduces the airflow of your unit and can lead to your air conditioner not working optimally. You can use a gardening hose to carefully clear off the fins of your air conditioner. You can also use a brush specifically made for cleaning the fins if you want to get a deeper cleaning. The fins on your air conditioner are delicate so we recommend you be careful when cleaning them. 

Trane air conditioner

There are several other things you can do yourself to take care of your air conditioner, but these are some of the basic ones. We do recommend that you have an HVAC technician check your unit once a year to make sure it’s working properly. HVAC technicians have equipment that can help your air conditioner run to its best ability that the average person doesn’t. While it may seem costly at the moment, an HVAC checkup can help detect problems early on. If an issue is treated early on, it will cost less than if it had been if left unchecked. 

What to Do When Things Go Wrong

Sometimes even with the best care, an air conditioner can stop working. While maintenance can stop a multitude of problems, there is always room for error when it comes to machines. Air conditioners are no different in that regard. When that happens, don’t blame yourself. The first thing you do is call an HVAC technician and talk about the issue at hand. Don’t leave any details out when you do. 

Some things you might want to include when calling an HVAC technician are:

  • Tell the HVAC technician if your air conditioner is making a weird noise and describe it. For example, maybe your air conditioner sounds like it’s rattling or something is banging around in it.

  • Has your air conditioner stopped working completely? If so, when did it stop working?

  • Is there a weird smell coming from your air conditioner? Sadly, we also recommend you describe it.

These are a few things an HVAC technician will appreciate hearing when you call them. The more details you can give them, the better they will be able to get a grasp of the situation. An HVAC technician will come out to check on your air conditioner unit. The best thing you can do when something goes wrong with your air conditioner is to call an HVAC technician. Don’t let it get worse and wait until the only thing that can be done is replacing the air conditioner. 

Old air conditioner


We hope this helped you to learn how to take care of your air conditioner and what to do when things go wrong. It can be difficult to know what to do when it comes to your air conditioner. Basic maintenance of your air conditioner will help you to save money and will save you a headache or two.

the difference between a condenser and an air handler


Do you know the differences between each of your HVAC units parts? Have you ever wondered what they are? In this month’s blog post, we’ll be answering what the difference is  between two main parts in your air HVAC unit: the condenser and the air handler. Both parts are crucial to your HVAC units and their ability to transport air up and down your vents, but they both vary. For example, a condenser turns gas into liquid and an air handler focuses solely on air regulation. We’ll explain more about them below. Now, let’s get into the blog post! 

What Is a Condenser?

A condenser is an outside part of the HVAC unit that, as mentioned above, turns gas into liquid. It releases and collects heat during the process it changes gas into liquid. It produces a considerable amount of heat as it cools the gas. Condensers are not only part of your HVAC unit, specifically your air conditioner, but they are part of refrigerators and steam power plants. In air conditioners, condensers cool heated up refrigerant vapor and use compressors to help move the refrigerant forward. A fan is then used to blow heat to cool the refrigerant vapor into a liquid. Tubing is then used to transport the air in and out of the building. While a condenser’s function may seem simple, it is extremely vital to your HVAC unit. Without a condenser, your HVAC unit wouldn’t be able to run smoothly.   

HVAC Condensers

What is an Air Handler?

An air handler’s sole purpose is to regulate the air in your furnace. Some parts in your air handler are filters, a motor, an evaporator coil, humidifier, and more. They are all interior parts. A filter is used to keep air clean and assure the quality of it. A motor is used to power the rest of the components in the air handler. An evaporator absorbs heat from inside your house and reuses it. A humidifier makes sure the humidity in the air is balanced. The air handler is not just one part of your furnace but a collective name for all the parts that come together to do the same job but in different segments. Every part is crucial to your HVAC unit. 

What Is the Difference?

The difference between an air handler and a condenser is their functions. As mentioned above, an air handler regulates air and a condenser turns gas into liquid. They have their similarities such as they both work together and if one fails then the other is affected because of it. However, their differences are numerous. For example, a condenser is an external piece of an HVAC unit. An air handler is a bit more complicated in that it is not just one piece of equipment but instead several. An air handler is also inside of the HVAC unit instead of outside of it. The difference between an air handler and condenser does not make one more important than the other, however. They are both necessary and when in doubt just remember; you need both a condenser and an air handler for your HVAC unit to work properly.


We hope we answered your questions in this month’s blog post. The different parts of an HVAC unit can be confusing even for us. If you have any more questions about the difference between a condenser and an air handler, or just HVAC questions in general, leave them in the comments below!

Signs Your HVAC System Needs Repairs


Have you ever wondered if your HVAC system needs to be repaired? Is your furnace acting up? Does your air conditioner make a strange whistling noise? While regular maintenance does help, sometimes your furnace and air conditioner can just act strangely. In this blog post, we will be addressing how to know if your HVAC system needs repairs or not and what to do going forward. There are some clear signs that your HVAC system needs to be repaired, but other times it is not so obvious. When in doubt, it never hurts to call your local HVAC company and ask them a few questions. You can give us a call if you live in Jefferson County and surrounding areas. We would be happy to answer any questions you had. For now though, let’s get into the blog post. 

How a Healthy HVAC System Acts

Before we go into detail on how an unhealthy HVAC system acts, we first need to go into detail about how a healthy HVAC system acts. Some signs that you have a healthy HVAC system are: your furnace always produces hot air, your air conditioner always produces cold air, all the rooms in your home are the same temperature if your furnace or air conditioner is on, your air conditioner and furnace doesn’t make a lot of noise, and there isn’t a buildup of dust in your home. Those are just a few signs that your HVAC system is running well and doesn’t need repairs but a rule of thumb is this; if you hear a weird noise or it stops working altogether, call an HVAC technician. If your HVAC system is acting strangely all you need to do is make a quick phone call. Now, that’s how a healthy HVAC system acts so in the next section, we’ll be covering how a healthy HVAC system doesn’t act. 

How a Healthy HVAC System Does Not Act

air conditioner repair

Has your air conditioner stopped working? Is there no air coming out of your vents? Have your electricity bills skyrocketed? All of those are signs that your HVAC system needs to be repaired and isn’t in the best condition it could be. If you notice that your air conditioner starts acting irregularly or seems to be performing less than optimally, you should call an HVAC technician to check it out. 

Some other signs that your HVAC needs repairs are:

  • Leaking
  • Your evaporator is frozen 
  • Moisture buildup 
  • Your fan motor is no longer turning
  • There is a strange odor from HVAC unit 
  • Your humidity levels are higher than usual

There are a lot of things that can go wrong with even the best HVAC unit. The number one way to prevent expensive repairs down the road is to go with a reputable HVAC company and make sure to get yearly checkups on your HVAC unit. You should also keep in mind the age of your HVAC unit as the older it gets the more prone it is to needing to be frequently repaired. Those are some of the most common signs that there might be something wrong with your HVAC unit. If you notice any of these signs, you should call an HVAC company. 

What to Do Next

So what should you do after you take a look at your HVAC system and determine if it needs repairs or not? If it doesn’t need repairs, then sit back and don’t worry. You should just make sure to get yearly checkups on your HVAC unit and try to keep it in the best possible condition you can. If you have noticed any signs mentioned in this post or your HVAC system is just acting oddly in general, you should contact a reputable HVAC company. When you contact an HVAC company, don’t be afraid to ask them questions as they should be happy to help. Everyone has had to deal with something breaking or not working properly and they will understand if you have any fears or need a little more information before doing anything. If you live in Jefferson County or the surrounding areas, you can contact Partney Heating and Cooling! We would be happy to answer any questions you had and give you advice on going forward. If it turns out your HVAC unit does need repairs, the company you contacted will send out an HVAC technician to look it over and tell you how much it will cost before repairing it. After that, you can decide what you would like to do next.

It’s even harder to figure out how it should be maintained. In this month’s blog post, we’re going to be covering the basics of ductwork and how to clean it. Here at Partney Heating and Cooling, we specialize in a variety of things that include ductwork cleaning and if cleaning your ductwork yourself sounds a little too risky for you, give us a call! For those of you who would like to DIY it though, this blog post is for you! 

What Is Ductwork?

Ductwork, to put it simply, is a system of metallic or non-metallic ducts that are connected together to transport something. When it comes to HVAC systems, they always transport air. The air can be heated air, filtered air, cooled air, and more. Air is classified differently when it comes to ductwork systems as each duct has a specific task that helps your HVAC system to work efficiently. Depending on the type of ductwork you have or the health of it, your system can work to its best ability or…not so much. You can read more about ductwork in our blog post “When Should You Replace Your Ductwork?” here

How Does Ductwork Work?

Ductwork may sound complicated to figure out, but once you get the hang of it, it isn’t. Ductwork takes air from your air conditioner or your furnace and distributes it. When you turn your thermostat up or down, air from your vents rush up to greet you as your ductwork is used as transportation for it. Ductwork, in all its complexity, is just a hallway for air to go up and down. It’s designed to be sealed and help maximize the efficiency of your HVAC system by transporting air quickly and without losing any of its heat or coolness in the process. When in doubt, just remember that ductwork is made to transport air. 

Tools Needed for Cleaning Ductwork:

  • Hvac Brush

 The first thing you should use is an HVAC brush. While you will be using a high volume vacuum cleaner the most, the brush will help you separate any clumps of dirt and dust that may build up in your ductwork. Some common buildup that you may find in your ductwork is dander, drywall, dust, dirt, and more. We also recommend you clean your ductwork even if your building or house is new construction as different materials can clog your ductwork. 

  • High Powered Air Compressor

The second thing you should use is a high powered air compressor. After breaking up the buildup in your ductwork as much as you can, it’s important that you use an air compressor for the buildup you were unable to break up using the HVAC brush. The air compressor is the perfect tool for picking up anything that your HVAC brush was unable to get. 

  • High Powered Vacuum

After breaking up any buildup in your ductwork, it’s crucial that you clean it up. That’s where a high powered vacuum cleaner comes in. Carefully using a vacuum cleaner, clean up the buildup to reduce the spread of airborne contaminants. 

Steps for Cleaning Ductwork

6. Use a high powered vacuum to clean up the loose buildup. 

7. Close up the ductwork entrance.  

8. Unseal your ductwork vents.

Furnace Basics 101


A furnace is a necessity for homes during the winter. The heat that a furnace brings can be comforting when it works and devastating when it doesn’t. Furnaces help to save lives by maintaining a livable temperature inside homes when winter is at it’s worse. Everyone knows the basics of what a furnace does, but how does it work? What exactly does it do? Is a furnace even necessary for your home? In this month’s blog post, those are the questions we hope to answer and more. 

How Does a Furnace Work?

There are several different types of furnaces, but the most common one is the gas furnace. In most cases, a gas furnace is powered by natural gas or propane. The first thing a gas furnace does is transfer gas to a burner, which then ignites it. The flames caused by the heated gas then raise the temperature of the air inside of the furnace which is then transferred through the air vents to inside the home by fans that circulate the air through the ducts.

A gas furnace is made out of different components such as the flue, ductwork, gas burner, thermostat, and more. The different components help to make sure everything runs smoothly and in cases where it doesn’t, tries to provide a solid backup plan until an HVAC technician can repair it. There is also waste, or excess air and gas, that the furnace takes into account. That’s where components such as the flue come into play. The flue carries out gas that was already used to heat air outside of the home. Excess air is returned to the furnace through return ducts, which is ductwork specifically designed for the purpose of returning said air. The functions of a furnace can be difficult to understand but when in doubt, just remember; it was designed to heat up air. That’s what all the fancy components are for. 

Furnace Repair

What Does a Furnace Exactly Do?

While we know what a furnace does and how it works, we don’t know exactly what it does. If furnaces only heat air, then isn’t it just a glorified fire? Does that mean we are nothing more than cavemen? 

Yes it does. 

The thing that a furnace has most in common with a fire is that the air heated inside of it is caused by combustion. Basically, the gas that is transferred into the furnace helps to cause a small explosion that heats up the temperature of the air inside of it. That used gas is then transferred to a safer place and new gas replaces it. The cycle repeats as air is transferred into homes. That is what a furnace does; it heats up the air inside of your home by causing a small explosion. Now, it is not as simple as that, as explained above, but it sure does sound cool, right? 

Is a Furnace Even Necessary?

This is a hard question to answer as it can go both ways. Depending on where you live and the specific needs of your household, it could be a yes or no. For example, if you live in Alaska, you’re going to need a furnace or you’ll have a higher chance of dying from hypothermia. If you live in Texas, the chances of you needing a furnace is low. Whether you need a furnace or not depends on your household needs and the climate you live in. If you’re still confused on whether you need a furnace or not, ask a reliable HVAC technician. 


The basic function of a furnace is to heat a home. A gas furnace is made out of a variety of parts. The parts allow it to successfully heat the air inside of a person’s home while making sure it is done as safely as possible. Whether you need a furnace or not in your home depends on your household’s needs. Partney Heating and Cooling has been installing and repairing furnaces for over twenty years.

When Should You Replace Your Ductwork?


Ductwork can be expensive to replace. Even the best ductwork wears down in time. You can try and properly seal it and have it repaired time and time again, but eventually, there is a time when you have to say goodbye to your ductwork. We can help you out if you’re wondering how much your new ductwork will cost, if it’s realistic for you to replace your ductwork yet, and how to increase the longevity of your ductwork. Here at Partney Heating and Cooling, we got your back. 

How Much Does Ductwork Cost?

The cost of ductwork varies on how much feet of it is needed and the material that is used. Non-metallic materials, for example, cost less but are more prone to tear. According to Home Advisor, the average cost of ductwork in 2022 is $10 – $20 per linear foot. One of the most common materials for ductwork is aluminum. It’s more rigid than non-metallic materials and less likely to have mold growth. You also need to take into account installation fees. The more dangerous and or difficult conditions HVAC technicians have to work in, the more installation fees are likely to cost. 


Signs You May Need to Replace Your Ductwork:

  • Leaking Issues

If your ductwork is leaking, it likely has a tear in it. Leaking issues can be a sign that you need to replace your ductwork. If you are unable to repair the tear or your ductwork is worn out, there is not much you can do except get it replaced. 

  • A Buildup of Dust in Your Home 

It can be hard to measure the amount of dust in your home, but at some point, it becomes a noticeable problem. If all your furniture is covered in dust, your dog is covered in dust, and your vacuum cleaner is begging you for a break, it may be time to replace your ductwork. A buildup of dust in your home is a sign that something is wrong with your HVAC system. Sometimes it can be your air conditioner, but it is likely your ductwork if it was installed incorrectly or your ductwork is reaching the end of its lifespan.  

  • Noise Level Increase

If you notice that there seems to be a noise increase coming from your vents, you might need to replace your ductwork. Noise disturbances from your ductwork can also happen because of blockage. You can avoid this by cleaning out your ductwork regularly. 

  • Varying Temperatures in Different Rooms 

If you can run from one room to the other and it feels like the difference between winter and summer, you likely have a problem. While it can be nice to feel a summer breeze in your home in one of your rooms and then have a cup of hot cocoa comfortably in another room, then it is likely your HVAC system is not working up to optimal standards. Different temperatures in different rooms of your home can be a sign that your ductwork is wearing out, has tears, or there is debris blocking a section of it causing the temperatures in your home to fluctuate. 

Replacing Ductwork

Replacing Your Ductwork

Eventually, you can no longer put off replacing your ductwork. When it is that time, it’s important you research heating and cooling companies before letting anyone into your home. Keep in mind that if it sounds too good to be true, it probably is. Once you find a trusted heating and cooling company, such as Partney Heating and Cooling, then it is time to figure out what ductwork material will best suit your needs and your budget. Metallic materials are likely to last longer and you won’t have to worry about any mold growth, but they tend to be more expensive and rigid. Non-metallic materials don’t last as long but are more flexible than metallic materials. However, there is the added worry about mold growth with non-metallic materials. You will have to get your ductwork cleaned more often. While replacing your ductwork can be stressful, the most important thing is that it is done correctly and then maintained.

How to Maintain Your Ductwork; the Do’s and Don’ts


  • Have Your Ductwork Regularly Cleaned 

To ensure its longevity, clean your ductwork often. Depending on the material your ductwork is made of and if you own any pets, you might need to have your ductwork cleaned more than other homeowners. A good rule of thumb is to have your ductwork cleaned every five years at least. 

  • Use Reliable Materials 

Your ductwork is only as good as what it is made of. Using unreliable materials will cost you more in the long run than it’s worth. Talk to your HVAC technician about what materials to use for your ductwork that will best suit your home. Do not just go with whatever is cheapest and saves you a few dollars. Your ductwork will thank you if don’t.

  • Have Trusted Professionals Install Your Ductwork 

As we covered in the “Replacing Your Ductwork” section, it’s important that you find a trusted heating and cooling company before having your ductwork installed. Once you do, ask them questions. See how long it will take the heating and cooling company to install the ductwork in your home and what materials they recommend for your needs. If they don’t answer your questions or don’t seem to know what they are doing, it might be best to look at a different heating and cooling company. 


  • Use the Cheapest Material Just Because It Is a Bargain Price 

We can not stress this enough; do not just go with the cheapest option before researching the material. Here at Partney Heating and Cooling, we like a good deal as much as anyone, but usually, they sound too good to be true for a reason. Don’t do it. 

  • Try to Install It Yourself 

While it can be beneficial to DIY some things, installing your ductwork is not one of them. Unless you are an HVAC technician, if you install your ductwork something is bound to go wrong. Duct tape can fix a lot of things, but it can not fix your ductwork. It sounds strange, we know, but trust us on this one. Just trust us. 

  • Forget About Your Ductwork 

Once you have your ductwork installed, it is crucial that you have it maintained over the years. You should have your ductwork inspected yearly, and have your ductwork cleaned regularly as mentioned in the Do’s section. Another thing you can do to maintain your ductwork is vacuum and dust regularly. 


At some point, you have to say goodbye to your ductwork. Not even the best ductwork lasts a lifetime. It’s important to know how much replacing your ductwork will cost, signs that you need to replace your ductwork, and how to take care of your ductwork so it will last as long as it can.

How Does an Air Conditioner Work?


Trying to figure out how your air conditioner works can be tough. One day it’s working and the next day it’s not. You mess with one little thing and suddenly boom! It no longer works. Luckily, here at Partney Heating and Cooling, we can help you out. You may be wondering, “how does my air conditioner work?” You may even be wondering what an air conditioner does. Does an air conditioner just cool air or does it do more? Is my air conditioner supposed to make that funny sound? Well, that’s what we’re here for! We’ll try to answer any questions you have about how your air conditioner works and if we don’t address the ones you were thinking of, leave us a comment below! 

What Does an Air Conditioner Do?

Air conditioners do a variety of things. Not only do they draw heat out of your house, but they filter your air to make sure the quality is up to standards. Bad quality air can lead to a number of health problems such as asthma, bronchitis, and even lung damage. Air conditioners remove moisture from the air to combat humidity. The more moisture in your air the harder your air conditioner works. More humidity in the air can lead to mold growth, dust mites, and sleep problems. Your air conditioner deals with this by taking the moisture out of the air.  

Air Conditioner

How Does an Air Conditioner Work?

Air conditioners work by drawing air in and out through a series of ductwork in your home. It acts as a filter for everything mentioned above. A click of a button, and cool rushes up to meet you. Your air conditioner takes warm air in, cools it, and then puts it back into your home. The warm air is cooled by being turned into a liquid before being converted to a gas again. You can tell your air conditioner is working by hearing the small, whirring sound it makes. If that sound is a loud one that sounds like rocks having a party inside of your ductwork, then we, unfortunately, have to inform you that’s not normal. It doesn’t matter even if it’s quite the rock party either. Alright, we’re sorry. We are the air conditioning experts, not the pun experts. We’ll stop now.

Common Issues

There are several common issues that can lead to your air conditioner not working the way you expect. Here are a few of them that are easy to answer and the most common ones we see:

  • Why is there no air coming out of my vents? 

It is likely your evaporator coil has frozen up. You can avoid this by changing your filter regularly. Here at Partney Heating and Cooling, we recommend you change your filters monthly. 

  • My air conditioner won’t work at all. What likely happened?

Sadly, your capacitor likely swell or blew up.  You’ll need to call an HVAC technician to fix it. The best way to avoid this is to have your air conditioner checked yearly by an HVAC technician and to change your filters regularly. Regular maintenance can solve several issues and save you thousands of dollars in the long run. 

  • My fan motor stopped turning, what do I do?

Your fan monitor likely stopped turning due to a bad capacitor. You will need to replace your capacitor and have an HVAC technician install it. Regular maintenance will help prolong the life of your capacitor. 

  • My evaporator randomly froze up, how do I fix it?

Your evaporator is likely low on Freon and you need a certified HVAC technician, such as Partney Heating and Cooling, to find the leak and fix where the leak is. You may need to replace your evaporator coil if the leak is bad enough. You should never have to replace Freon as your heating and cooling system is a closed system. 


An air conditioner does not just do one singular thing and instead does many things in order to keep your household running. A series of components helps it draw air in and release it out. Some of these components include your ductwork and vents. Most common issues can be solved by regularly maintaining your air conditioner.
