Whether it’s AC repair or total AC system replacement, there are a number of 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 increase your home’s energy efficiency and air quality. Of course we can’t talk about all of the variations in a short 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 components that move the air throughout your home, called the blower. It is usually situated inside the home and runs with both the heating and cooling pieces of your HVAC system. If you take a quick peep at an air handler, it might 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 working 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 control your comfort by transferring heat, rather than generating 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 has the blower, and several other components within. 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 need to know about air handlers: if you’re in the market 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 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 worry 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 components to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have included blowers that move the heated air into your ventilation and disperse into your home. Since furnaces have combustion chambers and create heat, they don't require some of the parts you'll find in a new air handler.
Air conditioners contain the condenser and are traditionally placed outside the home. One of the most common mix-ups with air conditioners is that they cool the existing air in your home. Air conditioners actually pull out heat from inside your home through a number 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 intricate 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 Houston climate is probably a little unrealistic, but there are a couple things that can be helpful to you as a homeowner.
