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 single blog post, so we’ll take a look at one of the routine inquiries we see at Bryant Heating & Cooling Service Experts: what’s the difference between an air conditioner and an air handler?

Air Handlers

An air handler contains the parts that move the air throughout your home, called the blower. It is typically situated inside the home and works with both the heating and cooling pieces of your HVAC system. If you take a quick glance 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 AC, an air handler works in tandem with your heat pump. Heat pumps are used to control your comfort by transferring heat, rather than producing it, and the air handler assists in moving 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 hard to understand and we're happy to explain the difference. An air handler includes the blower, and several other pieces in the unit. 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 should 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 most likely 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 won't need to think about an air handler. Air handlers tend to be used with heat pumps and help improve air flow throughout the house. Some air handlers also provide backup heating and cooling elements to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have built in blowers that move the heated air into your ducts and disperse through your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't have some of the parts you'll find in a typical air handler.

Air Conditioners

Air conditioners contain the condenser and are typically situated outside the home. One of the most common misunderstandings about air conditioners is that they cool the existing air in your home. Air conditioners actually pull out heat from inside your home through a number of parts 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 intricate than that, but the process itself is easy to break down and digest.

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