Whether it’s AC repair or total AC system replacement, there are a variety of 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 improve 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 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 located inside the home and runs with both the heating and cooling pieces of your HVAC system. If you take a quick glance at an air handler, it might closely resemble a furnace. Air handlers can run with an air conditioner and houses the indoor coil, used to cool and heat your home depending on which system it’s running with.
Air handler vs Heat Pump
Exactly like an air handler works with an air conditioner, an air handler works in tandem 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 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 pieces 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 should know about air handlers: if you’re searching 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 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 are usually mutually exclusive. If you have a furnace you shouldn't need to think about an air handler. Air handlers tend to be paired up with heat pumps and help regulate air flow throughout the home. Some units also provide extra 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 ventilation 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 modern air handler.
Air conditioners contain the condenser and are usually placed outside the home. One of the most common confusions 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 number of components 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 pulled 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 complex 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 West Palm Beach climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
