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 talk about 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 Komfort Air: 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 usually set inside the home and runs 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 work with an air conditioner and houses the indoor coil, used to cool and heat your home depending on which system it’s running with.

Air handler vs Heat Pump

Just like an air handler can work 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 moves all that heated or cooled air.

Air handler vs blower

Air handlers are not blowers. This can be confusing for some folks, but it's not too hard to understand and we're happy to explain the difference. An air handler contains the blower, and several other parts within. 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 ought to know about air handlers: if you’re searching for a conventional furnace or air conditioner, you’ll likely never need to know what an air handler is because it’s feasible that you won’t need one. However, if you’re searching 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 probably don't need to be concerned about an air handler. Air handlers tend to be used with heat pumps and help regulate air flow throughout the home. Some units also provide backup heating and cooling parts 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 hot air into your ventilation 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 new air handler.

Air Conditioners

Air conditioners contain the condenser and are typically situated 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 variety 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 pulled 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 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 pieces for the Charlotte climate is probably a little unrealistic, but there are a few things that can be helpful to you as a homeowner.
