Whether it’s AC repair or total AC system replacement, there are various 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 increase your home’s energy efficiency and air quality. Of course we can’t speak to all of the variations in a short blog post, so we’ll take a look at one of the routine inquiries we see at Strand Brothers 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 situated inside the home and runs with both the heating and cooling components of your HVAC system. If you take a quick peep at an air handler, it might closely resemble a furnace. Air handlers can operate with an air conditioner and houses 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 runs with an AC, an air handler works as a team with your heat pump. Heat pumps are used to control your comfort 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 confuses some folks, but it's not too complex and we're happy to explain the difference. An air handler has 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 part of a greater whole.
Here’s what you ought to know about air handlers: if you’re looking for a conventional furnace or air conditioner, you’ll 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 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 won't need to worry about an air handler. Air handlers tend to be paired up with heat pumps and help improve air flow throughout the house. Some air handlers also provide extra heating and cooling parts to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have their own blowers that move the hot air into your ducts and disperse throughout your home. Since furnaces have combustion chambers and make heat, they don't need some of the parts you'll find in a typical air handler.
Air conditioners contain the condenser and are usually 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 number of parts inside 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 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 complicated than that, but the process itself is easy to break down and digest.
Understanding all of your home’s heating and cooling parts for the Austin climate is probably a little idealistic, but there are a couple things that can be helpful to you as a homeowner.
