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 write about all of the variations in a single blog post, so we’ll take a look at one of the normal inquiries we see at Orangutan Home Services: 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 usually set inside the home and works with both the heating and cooling components of your HVAC system. If you take a quick look at an air handler, it can closely resemble a furnace. Air handlers can operate 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
Exactly like an air handler works with an air conditioner, 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 puzzles 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 part of a greater whole.
Here’s what you ought to know about air handlers: if you’re in the market for a conventional furnace or air conditioner, you’ll probably never need to know what an air handler is because it’s feasible that you won’t need one. However, if you’re searching 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 are usually mutually exclusive. If you have a furnace you shouldn't need to worry about an air handler. Air handlers tend to be setup with heat pumps and help improve air flow throughout the home. Some models also provide secondary 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 heated air into your ventilation 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 traditionally situated 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 passes across 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 complicated than that, but the process itself is easy to break down and comprehend.
Understanding all of your home’s heating and cooling pieces for the Tempe climate is probably a little impractical, but there are a few things that can be helpful to you as a homeowner.
