Why is My Furnace Short-Cycling in Pike Road, AL?

Furnace And Heat Pipes

An average cycle for a furnace is about 15 minutes or so in length, running roughly two to three cycles per hour. The issue of short-cycling happens when your home’s furnace runs shorter cycles than it should and has more cycles than normal. The following are some of the common causes of short-cycling and what you can do to get your furnace running well again in Pike Road, AL.

Clogged Air Filter

Your furnace’s air filter removes contaminants that would otherwise clog your system and prevent it from working properly. When the filter becomes clogged, it could then cause the system to overheat. Have your air filter changed at least every month to keep adequate air moving effectively through your furnace to avoid it overheating.

Faulty Ignition System

If the furnace’s ignition system malfunctions for any reason, the system will immediately turn off as a precautionary measure. It’s possible one of the components of your furnace became worn-out or dirty, but a professional HVAC service technician can examine it to know for sure. Scheduling routine furnace maintenance with a professional HVAC company can help to prevent the problem before it becomes a more serious and costly issue.


Overheating is a major concern for all types of furnaces. To prevent this problem from happening, your unit has heat sensors that will shut it down if it gets too hot. Several things can cause overheating, including but not limited to the following:

  • Insufficient airflow.
  • Clogged ventilation.
  • Mechanical issues.
