Whether it’s AC repair or total AC system replacement, there are various terms within the HVAC industry that can get puzzling for homeowners. Not to mention all of the different pieces of heating and air conditioning equipment that can be used to boost 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 routine inquiries we see at A1 Chesney Service Experts: 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 usually set inside the home and runs with both the heating and cooling pieces of your HVAC system. If you take a quick look 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 running with.
Air handler vs Heat Pump
Similar to how an air handler can work with an AC, an air handler works together with your heat pump. Heat pumps are used to regulate temperature 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 can be confusing for some folks, but it's not too complex and we're happy to explain the difference. An air handler contains 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 piece of the pie.
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 likely 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 shouldn't need to be concerned about an air handler. Air handlers tend to be paired up with heat pumps and help improve air flow throughout the house. Some models also provide secondary heating and cooling components to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have their own blowers that move the warmed air into your ductwork and disperse through 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 modern air handler.
Air conditioners contain the condenser and are typically 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 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 passes across 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 complex 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 Calgary climate is probably a little unrealistic, but there are a few things that can be helpful to you as a homeowner.
