Whether it’s AC repair or total AC system replacement, there are various 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 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 D & K Heating Service Experts: 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 usually set inside the home and operates with both the heating and cooling parts of your HVAC system. If you take a quick glance 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 running with.
Air handler vs Heat Pump
Exactly like an air handler can work with an air conditioner, an air handler works together with your heat pump. Heat pumps are used to heat and cool you home by transferring heat, rather than producing it, and the air handler helps move 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 components in the unit. 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 ought 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 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 aren't often found together. If you have a furnace you probably don't need to be concerned about an air handler. Air handlers tend to be paired up with heat pumps and help improve air flow throughout the house. Some units also provide backup heating and cooling elements to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have their own blowers that move the hot air into your ducts and disperse throughout your home. Since furnaces have combustion chambers and burn fuel to make heat, they don't need 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 variety of parts 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 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 comprehend.
Understanding all of your home’s heating and cooling pieces for the Belleville climate is probably a little idealistic, but there are a number of things that can be helpful to you as a homeowner.
