To fix a frozen AC coil after a power outage, immediately turn off your air conditioner and let the coil thaw completely. Once thawed, check and clean the air filter, ensure good airflow through vents, inspect the drain line for clogs, then restart the system on a low setting. If ice returns or you’re unsure, contact a professional HVAC technician.
When your air conditioner runs, refrigerant flows through thin metal tubes called the evaporator coil. The coil absorbs heat from indoor air. If airflow over the coil slows—often because of low air pressure or a stopped blower fan—the refrigerant stays very cold and moisture in the air freezes on the coil’s surface. A power outage can interrupt fan operation, leaving cold refrigerant in the coil once power returns. Ice builds up quickly, blocking airflow and causing your system to work harder or shut down to protect itself.
With these clear steps—turning off power, thawing the coil, restoring airflow, checking drains, and knowing when to call pros—you’ll resolve a frozen AC coil after an outage and keep your system running smoothly all summer long.
