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 short blog post, so we’ll take a look at one of the normal inquiries we see at D.A. Bennett Service Experts: 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 located inside the home and runs with both the heating and cooling parts 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 contains the indoor coil, used to cool and heat your home depending on which system it’s working 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 control your comfort by transferring heat, rather than creating it, and the air handler helps move all that heated or cooled air.
Air handler vs blower
Air handlers are not blowers. This confuses 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 parts 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 more than likely never need to know what an air handler is because it’s possible 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 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 probably don't need to worry about an air handler. Air handlers tend to be setup with heat pumps and help improve air flow throughout the home. Some air handlers also provide secondary heating and cooling parts to help out the heat pump. A furnace works a little differently. Instead of an air handler, furnaces have built in blowers that move the heated air into your ducts and disperse throughout your home. Since furnaces have combustion chambers and make 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 set outside the home. One of the most common misunderstandings about air conditioners is that they cool the existing air in your home. Air conditioners actually take heat from inside your home through a variety of components 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 drawn 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 intricate than that, but the process itself is easy to break down and comprehend.
Understanding all of your home’s heating and cooling components for the Albany climate is probably a little impractical, but there are a couple things that can be helpful to you as a homeowner.
