    Common Air Conditioner Repair Problems in Sunnyvale

    AC not cooling properly

    Low refrigerant, a dirty condenser coil, or a failing compressor can reduce cooling. We'll diagnose the root cause and restore comfort.

    AC blowing warm air

    Often caused by low refrigerant, a faulty compressor, or thermostat issues. We'll identify and fix the problem same day.

    AC making loud noises

    Banging, squealing, or grinding sounds indicate fan motor, compressor, or loose component issues. We'll pinpoint and repair the source.

    AC unit leaking water

    Clogged condensate drain lines or a frozen evaporator coil are common causes. We'll clear the blockage and prevent water damage.

    AC short cycling (turning on and off)

    This can indicate an oversized unit, refrigerant leak, or electrical issue. We'll diagnose the cycling problem.

    Thermostat not controlling AC

    Faulty wiring, a dead thermostat, or compatibility issues can prevent proper control. We'll repair or replace it.
