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 improve your home’s energy efficiency and air quality. Of course we can’t write about all of the variations in a short blog post, so we’ll take a look at one of the routine inquiries we see at Chief/Bauer Service Experts: 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 typically set inside the home and runs with both the heating and cooling parts of your HVAC system. If you take a quick peep at an air handler, it might 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
Similar to how an air handler works with an AC, an air handler works as a team with your heat pump. Heat pumps are used to heat and cool you home by transferring heat, rather than producing 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 too complex and we're happy to explain the difference. An air handler contains the blower, and several other parts inside. 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 probably never need to know what an air handler is because it’s possible 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 most 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 shouldn't need to be concerned about an air handler. Air handlers tend to be setup with heat pumps and help improve air flow throughout the home. Some air handlers 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 built in blowers that move the hot air into your ductwork and disperse throughout your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't need some of the parts you'll find in a modern air handler.
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 host of parts 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 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 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 Champaign climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
