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 confusing for homeowners. Not to mention all of the different pieces of heating and air conditioning equipment that can be used to improve 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 more common inquiries we see at Epperson 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 normally 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 holds the indoor coil, used to cool and heat your home depending on which system it’s working with. 

Air handler vs Heat Pump 

Just like an air handler can work with an air conditioner, 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 helps move all that heated or cooled air. 

Air handler vs blower 

Air handlers are not blowers. This confuses some of our customers, but it’s not that complicated and we’re happy to explain the difference. An air handler has 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 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 won’t need to worry about an air handler. Air handlers tend to be paired up with heat pumps and help regulate air flow throughout the home. Some models also provide secondary heating and cooling elements to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have built in blowers that move the hot air into your ventilation and disperse throughout your home. Since furnaces have combustion chambers and create heat, they don’t have some of the parts you’ll find in a modern 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 remove 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 drawn 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 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 Hilton Head Island climate is probably a little idealistic, but there are a few things that can be helpful to you as a homeowner.
