Why is my HVAC short cycling?

Keeping your HVAC running smoothly is essential for maintaining a comfortable home, so it's understandable if you're concerned when you start to notice that your system is short cycling. Short cycling occurs when the heating or cooling cycle ends too quickly and re-starts again, leading to compromised efficiency and comfort. There are many potential causes of this problem and, fortunately, solutions. In this blog post, we'll look at why your HVAC may be short cycling, what signs to look out for and what actions you can take to get things back on track.

What is short cycling, and why is it bad for my HVAC system?

HVAC short cycling is a fairly common HVAC failure and can lead to many other HVAC problems. HVAC short cycling occurs when the system turns on and off rapidly or runs for shorter intervals than necessary to achieve its normal temperature settings. Not only is this wasteful in terms of energy consumption, but it can cause serious damage to the HVAC unit as well. HVAC experts in Phenix City always recommend scheduling regular maintenance visits to help prevent HVAC short cycling and other issues. With preventative maintenance, HVAC systems run smoother, last longer, and reduce the strain on your wallet by making them more energy efficient.

If your HVAC is short cycling, you will likely observe a number of tell-tale symptoms. Look out for the following signs.


  • The system turns on and off frequently
  • Does not reach its optimal operating temperature
  • Loud clicking noises while the unit is operating



If you notice any of these symptoms, turn off the HVAC system right away, as this issue could result in irreversible damage to your unit if left unchecked. To prevent such a scenario and remedy the problem, it is best to contact a professional HVAC technician in Phenix City for assistance immediately.

By regularly maintaining your system and having an expert check it at least twice a year, more serious underlying problems may be avoided altogether. Taking these steps can enhance efficiency and extend the life of your HVAC unit considerably.

How can I prevent short cycling in my HVAC system from happening again in the future?
