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 improve your home’s energy efficiency and air quality. Of course we can’t talk 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 Rolf Griffin Service Experts Heating & Air Conditioning: what’s the difference between an air conditioner and an air handler?
An air handler contains the equipment that moves the air throughout your home, called the blower. It is typically set inside the home and operates with both the heating and cooling parts 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 holds the indoor coil, used to cool and heat your home depending on which system it’s operating with.
Air handler vs Heat Pump
Similar to how an air handler can work with an air conditioner, an air handler works as a team with your heat pump. Heat pumps are used to control your comfort 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 confuses some people, but it's not too complex and we're happy to explain the difference. An air handler has the blower, and several other components in the unit. 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 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 most 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 shouldn't need to worry about an air handler. Air handlers tend to be setup with heat pumps and help regulate air flow throughout the home. Some air handlers also provide backup heating and cooling elements to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have their own blowers that move the hot air into your ductwork and disperse into your home. Since furnaces have combustion chambers and create heat, they don't require some of the parts you'll find in a modern air handler.
Air conditioners contain the condenser and are typically set 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 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 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 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 comprehend.
Understanding all of your home’s heating and cooling pieces for the Fort Wayne climate is probably a little unrealistic, but there are a couple things that can be helpful to you as a homeowner.
