What is HVAC Short-Cycling and How Do I Identify It?

Posted by: A-1 Finchum Jan.23.2017

Are you looking for some troubleshooting tips for a short-cycling HVAC? When your HVAC is short-cycling, it means your air conditioner goes through its on-and-off cycles too frequently. When this happens, it makes it nearly impossible for your home to stay comfortable. To make matters worse, it can be a big drain on your energy bills. Short-cycling is a problem that requires immediate attention, as it can be very hard on all your air conditioning equipment.

What Does Short-Cycling Indicate?

Short-cycling can indicate a variety of issues. Your HVAC technician will use a process of elimination to determine if any of these apply:

• An oversized air conditioner: Many homes, especially newer ones, have an improperly sized unit.
• Clogged air filter: When your system’s air flow is blocked, it can cause the unit to overheat and shut down before a cycle is finished.
• Frozen evaporator coils: If your evaporator coils freeze over, your unit will not be able to function properly and will shut down
• Low refrigerant levels: Low refrigerant levels can cause your system to overheat and shut down.
• Electrical or control board issues: The control board must be working properly to determine when cycles should start and stop.

What to Do If Your A/C Is Short-Cycling?

If your air conditioning system is short-cycling, it is important to call your HVAC technician for assistance. Letting it continue to run this way can put a great deal of stress on your whole system.
