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 increase 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 Wesley Wood 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 normally situated inside the home and runs with both the heating and cooling components of your HVAC system. If you take a quick glance at an air handler, it might closely resemble a furnace. Air handlers can run with an air conditioner and houses 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 AC system, 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 moves all that heated or cooled air.
Air handler vs blower
Air handlers are not blowers. This puzzles some folks, but it's not that complicated and we're happy to explain the difference. An air handler includes the blower, and several other pieces in the unit. 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 ought to know about air handlers: if you’re in the market for a conventional furnace or air conditioner, you’ll more than likely never need to know what an air handler is because it’s probable 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 aren't often found together. If you have a furnace you probably don't need to think about an air handler. Air handlers tend to be setup with heat pumps and help improve air flow throughout the home. Some air handlers also provide extra heating and cooling parts to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have built in blowers that move the warmed air into your ducts and disperse through your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't have some of the parts you'll find in a modern air handler.
Air conditioners contain the condenser and are typically placed 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 pull out heat from inside your home through a host of parts 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 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 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 West Chester climate is probably a little unrealistic, but there are a number of things that can be helpful to you as a homeowner.
