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 talk about all of the variations in one 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 normally situated inside the home and runs with both the heating and cooling components of your HVAC system. If you take a quick glance at an air handler, it may closely resemble a furnace. Air handlers can run 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 can work with an AC system, an air handler works as a team with your heat pump. Heat pumps are used to regulate temperature 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 too complex 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 in the market for a conventional furnace or air conditioner, you’ll more than likely never need to know what an air handler is because it’s feasible that 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 likely be a part of your home’s HVAC system.

Air Handler vs. Furnace

Air handlers and furnaces don't normally pair together. If you have a furnace you shouldn't need to think about an air handler. Air handlers tend to be paired up with heat pumps and help manage air flow throughout the home. Some air handlers 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 included blowers that move the hot air into your ductwork and disperse through your home. Since furnaces have combustion chambers and create 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 traditionally set outside the home. One of the most common mix-ups with air conditioners is that they cool the existing air in your home. Air conditioners actually remove heat from inside your home through a variety of parts 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 drawn 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 transfer 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 complicated than that, but the process itself is easy to break down and comprehend.

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