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 variety of terms within the HVAC industry that can get baffling 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 normal inquiries we see at Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?

Air Handlers

An air handler contains the equipment that moves the air throughout your home, called the blower. It is normally set inside the home and works with both the heating and cooling components of your HVAC system. If you take a quick look 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 working with.

Air handler vs Heat Pump

Similar to how an air handler runs with an AC system, an air handler works together with your heat pump. Heat pumps are used to regulate temperature by transferring heat, rather than creating it, and the air handler helps move all that heated or cooled air.

Air handler vs blower

Air handlers are not blowers. This can be confusing for some people, but it's not too complex and we're happy to explain the difference. An air handler includes the blower, and several other components in the unit. You may have dampers, filters, mixing chambers and more in an air handler. The blower is just one piece of the pie.

Here’s what you ought to know about air handlers: if you’re looking 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 are usually mutually exclusive. If you have a furnace you won't need to worry about an air handler. Air handlers tend to be setup with heat pumps and help manage air flow throughout the building. Some models also provide extra heating and cooling parts to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have their own blowers that move the warmed air into your ductwork and disperse into 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 confusions with air conditioners is that they cool the existing air in your home. Air conditioners actually remove heat from inside your home through a host of pieces 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 Salt Lake City climate is probably a little idealistic, but there are a few things that can be helpful to you as a homeowner.
