Whether it’s AC repair or total AC system replacement, there are a number 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 improve your home’s energy efficiency and air quality. Of course we can’t talk about all of the variations in a short blog post, so we’ll take a look at one of the normal inquiries we see at Rob's Albertan 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 typically set inside the home and operates with both the heating and cooling parts of your HVAC system. If you take a quick look at an air handler, it might 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 working with.
Air handler vs Heat Pump
Similar to how an air handler runs with an AC, an air handler works in tandem with your heat pump. Heat pumps are used to regulate temperature 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 can be confusing for some of our customers, but it's not too complex 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 part of a greater whole.
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 feasible that 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 likely 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 probably don't need to worry about an air handler. Air handlers tend to be used with heat pumps and help manage air flow throughout the house. Some models also provide extra heating and cooling parts to help out the heat pump. A furnace works differently. Instead of an air handler, furnaces have included blowers that move the warmed air into your ducts and disperse through 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 typically 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 take 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 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 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 digest.
Understanding all of your home’s heating and cooling parts for the Edmonton climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
