Whether it’s AC repair or total AC system replacement, there are a variety 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 one blog post, so we’ll take a look at one of the routine inquiries we see at McElroy Service Experts: 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 normally located inside the home and operates with both the heating and cooling components of your HVAC system. If you take a quick peep at an air handler, it may 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 can work with an air conditioner, an air handler works as a team with your heat pump. Heat pumps are used to heat and cool you home 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 confuses 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 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 need to 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 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 are usually mutually exclusive. If you have a furnace you shouldn't need to think about an air handler. Air handlers tend to be used with heat pumps and help improve air flow throughout the home. Some air handlers also provide secondary heating and cooling parts to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have their own blowers that move the heated air into your ventilation and disperse throughout your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't need some of the parts you'll find in a modern air handler.
Air Conditioners
Air conditioners contain the condenser and are traditionally 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 take heat from inside your home through a variety 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 pulled 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 understand.
Understanding all of your home’s heating and cooling parts for the Grand Island climate is probably a little unrealistic, but there are a number of things that can be helpful to you as a homeowner.
