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 it. We can help you out if you’re wondering how much your new ductwork will cost, if it’s realistic for you to replace it just yet, or 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 it 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 it out 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 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 it 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 it 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 it inspected yearly, and have it cleaned regularly as mentioned in the Do’s section. Another thing you can do to maintain your ductwork is vacuum and dust regularly.
