Request AC repair help when your air conditioner freezes, ice appears on refrigerant lines, airflow gets weak, or the system stops cooling after running.
Share a few details and we will help connect you with HVAC service options in your area.
This page is for residential frozen-coil symptoms. Include where the ice appears, whether airflow is weak, and whether water leaks after thawing.
A frozen AC coil may show visible ice on refrigerant lines, weak airflow, warm air from vents, or water around the indoor unit after the ice melts.
The system may run for a while, stop cooling, then repeat the same pattern later.
Frozen coils can be linked to airflow restrictions, dirty filters, blower problems, dirty coils, refrigerant issues, or system operation outside normal conditions.
A provider can inspect the system and decide whether the problem is airflow, refrigerant, controls, or another cause.
If you see ice, note where it appears and whether airflow is weak. Avoid scraping coils or forcing the system to keep cooling while frozen.
Include whether the filter was recently changed and whether the system leaked water after thawing.
