Whether it’s AC repair or total AC system replacement, there are various 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 boost your home’s energy efficiency and air quality. Of course we can’t speak to all of the variations in a single blog post, so we’ll take a look at one of the routine inquiries we see at Midland Air Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?
An air handler contains the components 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 parts of your HVAC system. If you take a quick peep at an air handler, it may 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 operating with.
Air handler vs Heat Pump
Just like an air handler runs with an AC, an air handler works in tandem with your heat pump. Heat pumps are used to heat and cool you home by transferring heat, rather than creating 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 hard to understand and we're happy to explain the difference. An air handler contains the blower, and several other pieces within. 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 looking for a conventional furnace or air conditioner, you’ll probably 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 probably be a part of your home’s HVAC system.
Air Handler vs. Furnace
Air handlers and furnaces aren't often found together. If you have a furnace you shouldn't need to think about an air handler. Air handlers tend to be setup with heat pumps and help manage air flow throughout the building. Some models also provide backup 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 heated air into your ventilation 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 new air handler.
Air conditioners contain the condenser and are usually 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 number of pieces 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 brought into the system through return ducts and then go over 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 complicated 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 Columbia climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
