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 a number of terms within the HVAC industry that can get puzzling for homeowners. Not to mention all of the different pieces of heating and air conditioning equipment that can be used to boost your home’s energy efficiency and air quality. Of course we can’t speak to 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 components that move the air throughout your home, called the blower. It is typically located inside the home and operates with both the heating and cooling parts of your HVAC system. If you take a quick look at an air handler, it might closely resemble a furnace. Air handlers can operate with an air conditioner and houses the indoor coil, used to cool and heat your home depending on which system it’s working with.

Air handler vs Heat Pump

Similar to how an air handler works with an air conditioner, an air handler works as a team with your heat pump. Heat pumps are used to heat and cool you home by transferring heat, rather than generating it, and the air handler helps move all that heated or cooled air.

Air handler vs blower

Air handlers are not blowers. This confuses some of our customers, but it's not that complicated and we're happy to explain the difference. An air handler includes the blower, and several other components inside. You may have dampers, filters, mixing chambers and more in an air handler. The blower is just one component of many.

Here’s what you need 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 in the market for an electric heat pump, it’s helpful to know that an air handler will probably be a part of your home’s HVAC system.

Air Handler vs. Furnace

Air handlers and furnaces are usually mutually exclusive. If you have a furnace you probably don't need to think about an air handler. Air handlers tend to be paired up 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 on a different concept. Instead of an air handler, furnaces have their own blowers that move the hot air into your ventilation and disperse throughout your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't need some of the parts you'll find in a typical air handler.

Air Conditioners

Air conditioners contain the condenser and are usually 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 variety of components inside 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 brought into the system through return ducts and then passes across a refrigerant coil. As the warm air is blown across the cooled coil, heat is removed. Refrigerant lines then send 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 digest.

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