What's the Difference Between an Air Conditioner and Air Handler?

April 16, 2015

Whether it’s AC repair or total AC system replacement, there are various terms within the HVAC industry that can get confusing for homeowners. Not to mention all of the different pieces of heating and air conditioning equipment that can be used to improve your home’s energy efficiency and air quality. Of course we can’t write about all of the variations in a short blog post, so we’ll take a look at one of the more common inquiries we see at Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?

What is an Air Handler?

An air handler contains the equipment that moves the air throughout your home, called the blower. It is usually situated inside the home and runs with both the heating and cooling components of your HVAC system. If you take a quick peep at an air handler, it may closely resemble a furnace. Air handlers can work with an air conditioner and contains the indoor coil, used to cool and heat your home depending on which system it’s operating with.

Air handler vs Heat Pump

Similar to how an air handler works with an air conditioner, an air handler works in tandem with your heat pump. Heat pumps are used to control your comfort by transferring heat, rather than creating it, and the air handler moves all that heated or cooled air.

Air handler vs blower

Air handlers are not blowers. This confuses some folks, but it's not that complicated and we're happy to explain the difference. An air handler contains the blower, and several other pieces inside. You may have dampers, filters, mixing chambers and more in an air handler. The blower is just one part of a greater whole.

Here’s what you ought to know about air handlers: if you’re searching for a conventional furnace or air conditioner, you’ll more than likely never need to know what an air handler is because it’s possible you won’t need one. However, if you’re looking for an electric heat pump, it’s helpful to know that an air handler will most likely be a part of your home’s HVAC system.

Air Handler vs. Furnace

Air handlers and furnaces aren't often found together. If you have a furnace you won't need to worry about an air handler. Air handlers tend to be used with heat pumps and help regulate air flow throughout the home. Some units also provide backup heating and cooling parts to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have built in blowers that move the hot air into your ductwork and disperse through your home. Since furnaces have combustion chambers and make heat, they don't require some of the parts you'll find in a new air handler.

Air Conditioners

Air conditioners contain the condenser and are traditionally situated outside the home. One of the most common confusions with air conditioners is that they cool the existing air in your home. Air conditioners actually take heat from inside your home through a number of pieces in your system and expel it outside. The removal of heat is what makes the air feel cool, not the addition of cold air.

The warm air inside your home is pulled into the system through return ducts and then go over a refrigerant coil. As the warm air is blown across the cooled coil, heat is removed. Refrigerant lines then carry the heat outside. Now you’re left with cool, comfortable indoor air that you can enjoy on the hottest of days. And that’s pretty much it. Sure, the equipment is more complex than that, but the process itself is easy to break down and understand.

Understanding all of your home’s heating and cooling pieces for the Alliance climate is probably a little impractical, but there are a few things that can be helpful to you as a homeowner.
