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 improve 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 routine inquiries we see at Abbey Air Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?
An air handler contains the components that move the air throughout your home, called the blower. It is typically situated inside the home and operates 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 run 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
Similar to how an air handler can work with an air conditioner, an air handler works together with your heat pump. Heat pumps are used to control your comfort by transferring heat, rather than producing it, and the air handler helps move all that heated or cooled air.
Air handler vs blower
Air handlers are not blowers. This puzzles some people, 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 parts 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 in the market 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 searching 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 don't normally pair together. If you have a furnace you won't need to be concerned about an air handler. Air handlers tend to be setup with heat pumps and help manage air flow throughout the home. Some air handlers also provide backup heating and cooling parts to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have included blowers that move the hot air into your ducts and disperse throughout your home. Since furnaces have combustion chambers and 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 situated 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 take heat from inside your home through a number of parts in 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 drawn into the system through return ducts and then pass over a refrigerant coil. As the warm air is blown across the cooled coil, heat is removed. Refrigerant lines then carry 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 parts for the Oakville climate is probably a little idealistic, but there are a few things that can be helpful to you as a homeowner.
