Frozen AC Coil Questions in Mountain View

AC coils freeze due to: restricted airflow (dirty filter, blocked vents), low refrigerant, dirty evaporator coil, malfunctioning blower fan, or running AC when outdoor temps are too low. Turn off and thaw before diagnosis.
Turn off cooling but keep fan running to circulate warm air over coils. This takes 1-3 hours. Do not use heat sources to speed thawing. Once thawed, check filter before restarting. If it refreezes, call for service.
