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

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 write 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 Stallion Heating and Air Conditioning: what’s the difference between an air conditioner and an air handler? 

What is an Air Handler? 

An air handler contains the parts that move the air throughout your home, called the blower. It is usually situated inside the home and works with both the heating and cooling parts of your HVAC system. If you take a quick look 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 

Similar to how an air handler can work with an AC system, an air handler works in tandem with your heat pump. Heat pumps are used to regulate temperature by transferring heat, rather than creating 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 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 component of many. 

Here’s what you need to know about air handlers: if you’re in the market 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 in the market 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 are usually mutually exclusive. If you have a furnace you won’t need to be concerned about an air handler. Air handlers tend to be used with heat pumps and help manage air flow throughout the house. Some models also provide secondary 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 ventilation and disperse through your home. Since furnaces have combustion chambers and create heat, they don’t have some of the parts you’ll find in a typical air handler. 

Air Conditioners 

Air conditioners contain the condenser and are usually set 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 take heat from inside your home through a variety 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 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 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 complex than that, but the process itself is easy to break down and comprehend. 

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