During my system check, I found the indoor heat transfer media coil to be severely restricted with dust and pet hair collection.

Smithville AC Tune-up Got called to a home in downtown Smithville where the homeowner said the AC was starting up, running for about 45 seconds, and then shutting off without completing a cooling cycle. Diagnosed the system and found the evaporator coil was heavily restricted with dirt buildup, causing the system to overheat and cycle off prematurely. Cleaned the evaporator coil, checked the air filter and indoor airflow, and verified proper refrigerant pressures and electrical operation. Ran the AC through several full cooling cycles to confirm it was maintaining the call for cooling without shutting down early. AC system is running correctly now and the homeowner can stop watching the thermostat bounce.
