What’s the Difference Between an Air Conditioner and Air Handler?

Whether it’s AC repair or total AC system replacement, there are a number 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 single blog post, so we’ll take a look at one of the normal inquiries we see at Comfort Masters Service Experts: what’s the difference between an air conditioner and an air handler? 

What is an Air Handler? 

An air handler contains the equipment that moves the air throughout your home, called the blower. It is usually located inside the home and works with both the heating and cooling components of your HVAC system. If you take a quick peep at an air handler, it may 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 operating with. 

Air handler vs Heat Pump 

Just like an air handler works with an AC system, an air handler works in tandem 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 helps move 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 has the blower, and several other components within. 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 in the market 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 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 regulate air flow throughout the home. Some models also provide extra heating and cooling elements to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have built in blowers that move the warmed air into your ducts and disperse throughout 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 typically placed outside the home. One of the most common misunderstandings about 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 in 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 passes across a refrigerant coil. As the warm air is blown across the cooled coil, heat is removed. Refrigerant lines then carry 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 digest. 

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