The Difference Between a Condenser and an Air Handler

Introduction

Have you ever wondered about what the difference is between a condenser and an air handler? In this month’s blog post, we’ll be answering that very question. Both parts are crucial to your HVAC unit and its ability to transport air through your vents, but they vary. For example, a condenser turns refrigerant from a gas into a liquid and an air handler focuses 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 refrigerant from a gas into a liquid. It releases heat during the process of changing the refrigerant’s states. Condensers are not only part of your HVAC unit, specifically your air conditioner, but they are also part of refrigerators and steam power plants.

In air conditioners, condensers cool heated up refrigerant vapor (gas), and use compressors to move the refrigerant forward. A fan then removes heat from the refrigerant vapor as it cools into a liquid. After the refrigerant is cooled, tubing transports the air in and out of the home. 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.

What is an Air Handler?

An air handler’s sole purpose is to regulate the air inside your home. It regulates air by dispensing cold and hot air as needed. If you have an air handler, then you most likely do not need a furnace.

Some parts in your air handler are filters, a blower motor, an evaporator coil, and more. They are all interior parts. A filter is used to keep air clean and assure the quality of it. A blower motor controls airflow. An evaporator absorbs heat from the air, cooling it. It also turns refrigerant from a liquid into a gas.

The air handler is not just one part of your HVAC system 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 Between a Condenser and an Air Handler?

The difference between an air handler and a condenser lies in their functions. An air handler regulates air, and a condenser turns refrigerant from a gas into a liquid. They have their similarities, such as they work together and if one fails, then the other is affected. Air handlers and condensers also both use electricity. However, they have many differences. For example, a condenser is located outdoors and air handler is located indoors.

The difference between an air handler and a condenser does not make one more important than the other. They are both necessary, and when in doubt remember; you need both a condenser and an air handler for your HVAC unit to work properly.
