Whether it’s AC repair or total AC system replacement, there are various terms within the HVAC industry that can get confusing 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 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 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 equipment that moves the air throughout your home, called the blower. It is normally located inside the home and works with both the heating and cooling parts of your HVAC system. If you take a quick glance at an air handler, it can closely resemble a furnace. Air handlers can work 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
Similar to how an air handler runs with an air conditioner, an air handler works together 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 folks, but it's not too complex and we're happy to explain the difference. An air handler contains the blower, and several other pieces 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 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 possible 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 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 shouldn't need to worry about an air handler. Air handlers tend to be paired up with heat pumps and help regulate air flow throughout the building. Some air handlers also provide extra heating and cooling parts to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have built in blowers that move the hot air into your ventilation 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 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 host of pieces 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 brought 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 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 comprehend.
Understanding all of your home’s heating and cooling pieces for the Denver climate is probably a little idealistic, but there are a couple things that can be helpful to you as a homeowner.
