What short cycling looks like
The thermostat calls for cooling, the system starts, then it shuts back down after only a short run. It may repeat this over and over while the house still feels warm, sticky, or uneven room to room.

AC starts and stops too often? Track the pattern before guessing.
Short cycling means the AC is starting and stopping before the home is comfortable. The cause can be simple or serious, so the useful first step is to notice the pattern and request a diagnostic instead of guessing at a part.
Why it should be checked
Short cycling can point to airflow restriction, thermostat placement or setup, a drain safety switch, ice, electrical controls, an outdoor unit issue, or equipment stress. A $95 Springfield Diagnostic helps separate the symptom from the actual cause before repair pricing starts.
Read the diagnostic pageWhat you can safely check first
Check whether the filter is badly restricted, whether supply vents are open, whether the thermostat is set to cooling, and whether water or ice is visible. If you smell electrical burning, see smoke, or the breaker keeps tripping, stop using the equipment and use the appropriate emergency or utility path.
