Whether it’s AC repair or total AC system replacement, there are various 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 write about all of the variations in one 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 parts that move the air throughout your home, called the blower. It is typically situated inside the home and works with both the heating and cooling components of your HVAC system. If you take a quick look at an air handler, it can 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
Exactly like an air handler can work with an air conditioner, an air handler works together 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 can be confusing for some folks, but it's not too hard to understand and we're happy to explain the difference. An air handler has the blower, and several other components in the unit. 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 need to know about air handlers: if you’re looking for a conventional furnace or air conditioner, you’ll probably never need to know what an air handler is because it’s possible 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 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 won't need to worry about an air handler. Air handlers tend to be paired up with heat pumps and help regulate air flow throughout the home. Some models also provide extra heating and cooling parts to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have included blowers that move the hot air into your ventilation and disperse into your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't require some of the parts you'll find in a new air handler.
Air Conditioners
Air conditioners contain the condenser and are traditionally set 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 remove heat from inside your home through a number 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 passes across 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 complicated than that, but the process itself is easy to break down and understand.
Understanding all of your home’s heating and cooling components for the Edmonton climate is probably a little idealistic, but there are a couple things that can be helpful to you as a homeowner.
