The customer contacted us for AC repair after the unit began short cycling and failing to maintain a consistent temperature. During the diagnostic, we found a failing thermostat and a partially clogged air filter that were interfering with system performance. We replaced the thermostat, installed a new filter, and verified that refrigerant levels and airflow were within the correct range. The AC system now runs smoothly and efficiently, keeping the home comfortable while reducing energy waste and the risk of future breakdowns.
