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 improve your home’s energy efficiency and air quality. Of course we can’t speak to all of the variations in a short blog post, so we’ll take a look at one of the normal inquiries we see at Service Experts Heating & Air Conditioning: 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 typically set inside the home and operates with both the heating and cooling pieces of your HVAC system. If you take a quick look at an air handler, it may closely resemble a furnace. Air handlers can operate with an air conditioner and houses 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 together with your heat pump. Heat pumps are used to control your comfort by transferring heat, rather than generating it, and the air handler assists in moving all that heated or cooled air.
Air handler vs blower
Air handlers are not blowers. This can be confusing for some of our customers, but it's not too complex and we're happy to explain the difference. An air handler includes 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 component of many.
Here’s what you ought 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 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 aren't often found together. If you have a furnace you probably don't need to think about an air handler. Air handlers tend to be used with heat pumps and help regulate air flow throughout the house. Some models also provide secondary heating and cooling components to help out the heat pump. A furnace works 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 require some of the parts you'll find in a typical air handler.
Air conditioners contain the condenser and are typically situated 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 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 drawn 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 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 complicated than that, but the process itself is easy to break down and comprehend.
Understanding all of your home’s heating and cooling pieces for the Naples climate is probably a little impractical, but there are a number of things that can be helpful to you as a homeowner.
