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 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 one blog post, so we’ll take a look at one of the normal inquiries we see at Golden Seal 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 glance at an air handler, it can closely resemble a furnace. Air handlers can run 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 can work with an AC system, an air handler works as a team with your heat pump. Heat pumps are used to control your comfort by transferring heat, rather than producing it, and the air handler helps move all that heated or cooled air.

Air handler vs blower

Air handlers are not blowers. This puzzles 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 pieces 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 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 feasible that 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 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 probably don't need to be concerned about an air handler. Air handlers tend to be used with heat pumps and help improve air flow throughout the house. Some models also provide backup heating and cooling elements to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have included blowers that move the heated air into your ducts and disperse through your home. Since furnaces have combustion chambers and make heat, they don't need some of the parts you'll find in a new air handler.

Air Conditioners

Air conditioners contain the condenser and are usually 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 take heat from inside your home through a host 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 brought into the system through return ducts and then pass over 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 understand.

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