Learning About Commercial HVAC Systems

Hello, my name is Jacob. I would like to talk about proper installation and repair of the HVAC system in your commercial building. Full scale HVAC systems for commercial buildings require ongoing maintenance and repairs to keep every floor and room at a comfortable temperature. These temperature control systems also control the air quality in the building by sending the airflow through filter elements. My site will cover all aspects of the upkeep needed for these systems. I will also talk about the benefits of keeping your air quality and temperatures at desirable levels. Thanks for coming to visit my website.

3 Parts In Your Air Handler That Might Go Bad And Need To Be Replaced By An HVAC Repair Technician

Isaiah Chapman

Since the air handler in your HVAC system works with both the air conditioner and furnace, it gets a lot of wear and tear. The air handler may run most of the year if you also use your HVAC in fan mode.

To keep the air handler in good shape, it's important to keep up with maintenance so the parts stay clean and serviced. Still, the unit may occasionally need help from an HVAC repair technician. Here are some parts in the air handler that might go bad and need to be repaired.

1. The Blower Motor

The blower motor is responsible for spinning the blower that moves air through your house. In the winter, it blows warm air through the ducts, and in the summer it blows cool air into your home. As the fan spins, it collects dust. This is one reason it's important to have your HVAC serviced and cleaned regularly and to change your filter when it's time.

If the blower gets too dusty, it is hard to spin and that can cause the motor to burn out. A burned-out motor has to be replaced by an HVAC repair technician.

2. The Control Board

The control board in the air handler controls the thermostat, furnace, and air conditioner. If it goes bad, the HVAC may not turn on or shut off. It may be hard to control the temperature in your home. When the control board is bad, the repair technician can check it to determine what part is affected. If one part of the control board is bad, the HVAC technician will probably replace the entire board.

Replacing the control board has to be done carefully since it has a lot of wires connected to it and they need to go back on the new board in the same places they were on the old board.

3. The Limit Switch

A limit switch controls when the blower in the air handler shuts off and starts up. It synchronizes the blower with the thermostat so the blower doesn't start too soon or stay on too long, as both of these situations could affect how well your HVAC heats or cools your house.

A bad limit switch needs to be replaced so your furnace operates safely and so your air conditioner can cool your house without driving up your power bill. The switch is a small part that an HVAC repair technician can test to make sure it's bad and if so, replace it with a new switch.
