What is an Air Handler?
An air handler is a machine designed to distribute air from the heating, ventilation, and air conditioning (HVAC) unit to the air ducts within a building. It is responsible for the warm or cool air that you may be feeling right now. It’s a crucial part of every HVAC unit and, without it, your entire ventilation system would be useless.

How Do Air Handlers Work?
Simply put, air handlers get the air from the HVAC outside to the inside of your house. When people think of air conditioners, they typically think of the loud unit stationed outside their house. However, the crucial aspect of air conditioning is really the air handler. Without it, the conditioned air couldn’t get into your house.
These machines are stationed inside your home, actively taking the air and getting it to be evenly spaced around the house. In some instances, there may be several smaller handlers placed within a home or building in order to make sure there is equal distribution. Instead of forcing your HVAC to both create the air and distribute it, the air handler takes a bit of the burden off of the main machine.
Handlers also reclaim air and direct it back to the HVAC. While the handler is also pushing air through the vents, it is circulating air back into the handler itself. The air is pressurized into the HVAC, which allows the unit to either heat or cool the air down again. Once the HVAC has performed its function, the handlers take in the newly conditioned air and pushes it back out into the home.
Air Handler Parts
The tool that allows a handler to take in air is called the blower. This is actually somewhat of a mislabel, as the blower serves two purposes. The first is to circulate the air through the house and then take it back in again. Without the blower, the air handler would have no function.
Sometimes, the air flow within the home needs to get controlled. When this happens, the air handler utilizes its damper. The damper directly controls the amount of air that flows through the house. Once the air has been taken in by the blower, it circulates through the damper.
An air handler will circulate a tremendous amount of air in its lifetime. To keep it clean and operational, it is important to get a filter. In the course of its journey, air picks up a lot of debris, dust, and potential toxins. In order to provide better air, filters are placed within the handler itself. After pushing its way through the blower and the damper, the air gets cleaned and recirculated into the home.
Some air handlers also have the option of additional heating or cooling pieces inside of them. This would act as an additional or auxiliary conditioning function if need be. Many air handlers function well without the additions, but the aid provided can help the potentially overworked HVAC.
Air Handler Troubleshooting
Air handlers are workhorses. They consistently push out the air you want evenly and without problems. Every once in awhile, an air handler will need troubleshooting. Here are some common questions to ask:
Q: Are the filters clogged?
A: If the airflow in your home has significantly reduced, there is an easy check you can make. The filters inside the handler are literally taking in all of the air in your house. This means there will be a lot of dirt and debris in them, which means they will get clogged at some point. Check the status of the filter and see if they need to be replaced.
Q: Have the blowers stopped working?
A: Occasionally, one of the fans may start malfunctioning within the air handler. These blowers will stop distributing air around the house, causing trouble for your entire system. If the blowers have stopped operating, we would need to first make sure it is mechanical failure by isolating potential environmental hazards that could befall it (i.e. build up of residue preventing unobstructed movement).
Q: Are the dampers stuck?
A: If there is little to no circulation coming from your vents and you know the filters are clean and unclogged, check your dampers. Since the damper controls airflow coming into and exiting the home, they could be stuck. Tex-Perts would need to make sure the dampers are able to move fluidly. If they aren’t, it may be necessary to replace them or do serious work on your handler.
Q: Are the heating and cooling apparatuses getting in the way?
A: Your air handler may be using heating or cooling tools. Sometimes, these tools break down or even freeze during operation. If that’s the case, make sure these mechanisms are working and not getting in the way of the handler.
Q: Is everything actually working?
A: If the blower is working, the damper moves fine, the filters are clean, and everything is in good shape, you might have another problem. If the air handler works, you may need to address possible issues with your HVAC unit. Make sure your outside unit is running. If not, call the Tex-Perts.
