Whether it’s AC repair or total AC system replacement, there are a variety 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 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 Finch Air Conditioning & Heating: 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 located inside the home and works with both the heating and cooling parts of your HVAC system. If you take a quick peep at an air handler, it might 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 operating with.
Air handler vs Heat Pump
Just like an air handler runs with an AC system, an air handler works in tandem with your heat pump. Heat pumps are used to regulate temperature by transferring heat, rather than creating it, and the air handler assists in moving 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 includes the blower, and several other parts within. 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 should know about air handlers: if you’re looking for a conventional furnace or air conditioner, you’ll more than likely never need to know what an air handler is because it’s feasible that 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 think about an air handler. Air handlers tend to be setup with heat pumps and help regulate air flow throughout the house. Some units also provide extra 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 warmed air into your ductwork and disperse throughout your home. Since furnaces have combustion chambers and create heat, they don't have some of the parts you'll find in a typical air handler.
Air conditioners contain the condenser and are typically set 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 remove heat from inside your home through a number 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 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 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 La Porte climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
