Why Your AC Keeps Turning On and Off

Cool Talk with Hartzell's | Your HVAC Questions, Answered! · Jul 20, 2026 · 20m · transcript

Give Use A Shout

Your AC kicks on, runs for a short burst, shuts off, then does it again a few minutes later, over and over. That is called short cycling, and it is hard on the equipment and on your comfort. In this episode I walk through what causes it, from a thermostat sitting in the sun or a dirty filter choking airflow, to a frozen coil, an oversized system, a refrigerant leak, or a failing part. I cover what you can safely check yourself and when it is time to call somebody. Call 405-375-4822 or book at hartzellsheatair.com. More episodes: https://hartzellsheatair.com/podcast/
