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 confusing for homeowners. Not to mention all of the different pieces of heating and air conditioning equipment that can be used to increase 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 more common inquiries we see at Peitz Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?

Air Handlers

An air handler contains the components that move the air throughout your home, called the blower. It is normally located inside the home and operates with both the heating and cooling pieces of your HVAC system. If you take a quick peep at an air handler, it might closely resemble a furnace. Air handlers can operate with an air conditioner and contains the indoor coil, used to cool and heat your home depending on which system it’s running with.

Air handler vs Heat Pump

Exactly like an air handler runs with an AC, an air handler works in tandem with your heat pump. Heat pumps are used to regulate temperature 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 people, but it's not that complicated and we're happy to explain the difference. An air handler contains 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 looking for a conventional furnace or air conditioner, you’ll likely never need to know what an air handler is because it’s probable 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 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 paired up with heat pumps and help regulate air flow throughout the home. Some units also provide secondary heating and cooling elements 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 warmed air into your ventilation and disperse throughout 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 modern air handler.

Air Conditioners

Air conditioners contain the condenser and are typically 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 number of pieces within 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 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 complex than that, but the process itself is easy to break down and understand.

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