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 improve your home’s energy efficiency and air quality. Of course we can’t talk about 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 parts that move the air throughout your home, called the blower. It is typically situated inside the home and operates with both the heating and cooling pieces of your HVAC system. If you take a quick glance at an air handler, it may closely resemble a furnace. Air handlers can operate with an air conditioner and holds the indoor coil, used to cool and heat your home depending on which system it’s running with.
Air handler vs Heat Pump
Just like an air handler can work with an air conditioner, an air handler works as a team 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 people, but it's not too complex and we're happy to explain the difference. An air handler includes 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 piece of the pie.
Here’s what you need 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 don't normally pair together. 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 regulate air flow throughout the building. Some models also provide backup heating and cooling parts to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have included blowers that move the heated air into your ductwork and disperse through your home. Since furnaces have combustion chambers and create 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 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 take 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 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 complex than that, but the process itself is easy to break down and understand.
Understanding all of your home’s heating and cooling pieces for the Hilton Head Island climate is probably a little unrealistic, but there are a couple things that can be helpful to you as a homeowner.
