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 various 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 boost your home’s energy efficiency and air quality. Of course we can’t talk about all of the variations in one blog post, so we’ll take a look at one of the more common 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 parts that move the air throughout your home, called the blower. It is normally set inside the home and works with both the heating and cooling pieces of your HVAC system. If you take a quick look 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 runs with an AC, an air handler works together with your heat pump. Heat pumps are used to heat and cool you home by transferring heat, rather than generating it, and the air handler moves all that heated or cooled air.

Air handler vs blower

Air handlers are not blowers. This puzzles some folks, but it's not too complex and we're happy to explain the difference. An air handler contains 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 should know about air handlers: if you’re searching for a conventional furnace or air conditioner, you’ll probably 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 probably 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 shouldn't need to worry about an air handler. Air handlers tend to be used with heat pumps and help manage air flow throughout the home. Some units also provide extra heating and cooling components to help out the heat pump. A furnace works a little differently. 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 make heat, they don't require some of the parts you'll find in a modern air handler.

Air Conditioners

Air conditioners contain the condenser and are traditionally 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 pull out heat from inside your home through a variety of components 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 go 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 complicated than that, but the process itself is easy to break down and understand.

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