Common Air Conditioner Repair Problems in Atherton
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.
