Whether it’s AC repair or total AC system replacement, there are a variety of terms within the HVAC industry that can get puzzling 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 talk 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 Service Experts Heating & Air Conditioning: 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 located inside the home and runs with both the heating and cooling pieces 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 operating with.
Air handler vs Heat Pump
Exactly like an air handler runs with an air conditioner, an air handler works together with your heat pump. Heat pumps are used to heat and cool you home by transferring heat, rather than generating 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 that complicated and we're happy to explain the difference. An air handler includes the blower, and several other components 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 should 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 probable 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 don't normally pair together. If you have a furnace you shouldn't need to worry about an air handler. Air handlers tend to be used with heat pumps and help regulate air flow throughout the home. Some units also provide backup heating and cooling components to help out the heat pump. A furnace works 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 make heat, they don't need some of the parts you'll find in a new air handler.
Air conditioners contain the condenser and are traditionally 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 pull out heat from inside your home through a variety of pieces in 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 pieces for the Kingston climate is probably a little impractical, but there are a few things that can be helpful to you as a homeowner.
