What’s Short-Cycling, and Why is It Bad for Your HVAC System?

December 19, 2021

Your HVAC system accounts for a sizable chunk of your energy bills in Duval, FL. Therefore, it’s essential it functions efficiently. Sometimes, the HVAC system begins to run in quick bursts called short cycles that do little to change the temperature of your home. Here’s what short-cycling actually is and why it’s so bad for your HVAC system.

What’s Short-Cycling?

Short-cycling occurs when your system turns on, runs for only a short amount of time, then turns off again. This happens quite quickly and many times over the course of an hour. Anything more than 10 times an hour is too many and signals short-cycling instead of normal operation.

Potential HVAC Problems

Your system generates a large burst of energy when it turns on. When this happens too often, like with short-cycling, it wastes a lot of energy. This wears down your system prematurely and causes your energy bills to steadily rise as the problem worsens. This excess energy also has a negative impact on the environment.

Causes of Short-Cycling

Your system may begin to short-cycle for a variety of reasons. Some of them include:

  • Faulty flame sensor.
  • Clogged air filter.
  • Airflow issues.
  • Overheating.
  • Improperly sized ducts or system.

Signs Your HVAC System is Short-Cycling

The main sign of a short-cycling HVAC system is frequent startups and shutdowns. You may also notice rising bills or hot and cold spots throughout your home./p>
