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 a single blog post, so we’ll take a look at one of the more common inquiries we see at Climate Control Service Experts: what’s the difference between an air conditioner and an air handler?
What is an Air Handler?
An air handler contains the equipment that moves the air throughout your home, called the blower. It is usually set inside the home and operates with both the heating and cooling pieces of your HVAC system. If you take a quick glance at an air handler, it can closely resemble a furnace. Air handlers can operate with an air conditioner and contains 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 runs with an air conditioner, 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 generating 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 of our customers, but it's not that complicated and we're happy to explain the difference. An air handler contains the blower, and several other components inside. 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 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 feasible that 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 probably don't need to be concerned about an air handler. Air handlers tend to be setup with heat pumps and help regulate air flow throughout the home. 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 included blowers that move the hot air into your ducts and disperse through your home. Since furnaces have combustion chambers and create heat, they don't have some of the parts you'll find in a new air handler.
Air conditioners contain the condenser and are typically placed 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 variety 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 drawn 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 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 complex 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 Mobile climate is probably a little idealistic, but there are a number of things that can be helpful to you as a homeowner.
