Whether it’s AC repair or total AC system replacement, there are a variety 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 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 Roland J. Down Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?
An air handler contains the parts 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 parts 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 works with an AC system, an air handler works as a team with your heat pump. Heat pumps are used to heat and cool you home 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 puzzles some of our customers, but it's not too complex and we're happy to explain the difference. An air handler contains the blower, and several other parts inside. 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 searching 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 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 won't need to worry about an air handler. Air handlers tend to be paired up with heat pumps and help improve air flow throughout the home. Some models also provide backup heating and cooling parts to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have built in blowers that move the warmed air into your ventilation and disperse through your home. Since furnaces have combustion chambers and create heat, they don't require some of the parts you'll find in a new 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 pull out heat from inside your home through a host of components 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 brought 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 complex than that, but the process itself is easy to break down and comprehend.
Understanding all of your home’s heating and cooling components for the Albany climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
