Most calls close on the first visit. Every repair carries a 1-year parts + labor warranty — labor too.
Usually low refrigerant or a failing compressor. We check subcool/superheat first — if charge is off, there's a leak; we locate it with electronic detection.
Typically a shorted compressor winding, failing capacitor, or undersized wire. We measure amp draw against nameplate + verify 230V on both legs.
Dirty evaporator, frozen coil (low charge or restricted airflow), or a failing condenser fan motor. All three are first-visit repairs.
Clogged condensate drain in 90% of cases. Flush with vinegar, clear the trap, inspect secondary drain pan for safety.
Oversized equipment, failing capacitor, or low refrigerant charge. We confirm with a run-capacitor microfarad reading.
