WHY DOES MY HVAC SYSTEM KEEP TURNING ON AND OFF (SHORT CYCLING)?

 

Homeowners across North Texas frequently report a frustrating issue known as short cycling, where an HVAC system turns on and off repeatedly without completing a full cooling or heating cycle. According to industry technicians, this behavior is often caused by underlying problems such as clogged air filters, low refrigerant levels, thermostat malfunctions, or an oversized unit that cools the home too quickly and shuts down prematurely. Short cycling can also occur when safety sensors trip due to overheating or restricted airflow, forcing the system to shut off as a protective measure. Experts note that this repeated starting and stopping puts heavy strain on motors and compressors, dramatically increasing energy use and accelerating wear on the system, often resulting in expensive repairs if ignored.
