What’s the Difference Between an Air Conditioner and Air Handler?
Whether it’s AC repair or total AC system replacement, there are various 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 improve your home’s energy efficiency and air quality. Of course we can’t speak to 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 Service Experts Heating, Air Conditioning & Plumbing: 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 usually situated inside the home and operates with both the heating and cooling parts of your HVAC system. If you take a quick glance at an air handler, it may 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 operating with.
Air handler vs Heat Pump
Similar to how an air handler runs with an AC system, 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 can be confusing for some people, but it’s not that complicated 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 should know about air handlers: if you’re searching 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 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 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 paired up with heat pumps and help manage air flow throughout the building. Some models also provide backup heating and cooling parts to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have included blowers that move the warmed air into your ductwork and disperse throughout your home. Since furnaces have combustion chambers and burn fuel to make heat, they don’t require some of the parts you’ll find in a new 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 take heat from inside your home through a number 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 brought 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 carry 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 components for the the U.S. climate is probably a little unrealistic, but there are a number of things that can be helpful to you as a homeowner.
