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 boost 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 routine inquiries we see at TML Service Experts: 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 situated inside the home and runs with both the heating and cooling components of your HVAC system. If you take a quick peep at an air handler, it can closely resemble a furnace. Air handlers can run 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
Exactly like an air handler runs 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 producing it, and the air handler assists in moving all that heated or cooled air.
Air handler vs blower
Air handlers are not blowers. This confuses some folks, but it's not too complex and we're happy to explain the difference. An air handler has the blower, and several other pieces within. 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 ought 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 feasible that 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 most 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 think about an air handler. Air handlers tend to be paired up with heat pumps and help improve air flow throughout the house. Some units also provide backup heating and cooling elements 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 require some of the parts you'll find in a typical air handler.
Air conditioners contain the condenser and are traditionally set outside the home. One of the most common confusions 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 variety of parts inside 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 pulled 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 send 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 Boise climate is probably a little unrealistic, but there are a number of things that can be helpful to you as a homeowner.
