AC unit freezing up in Austin
What to do when your AC freezes up
A frozen AC unit can have more than one possible explanation. Use safe observations to describe what you see, then use the Air Conditioning Repair service path when the problem needs professional inspection.
Start with safe observations
If you see ice on an accessible part of the system, avoid dismantling the equipment or trying to repair it yourself. Note where the ice appears, whether the system is still blowing air, and whether you see water near the indoor unit. If you notice unusual smells, electrical concerns, or water spreading near wiring or other equipment, turn the system off if you can do so safely and arrange professional help.
What a frozen AC may indicate
Freezing can be associated with an airflow problem, a refrigerant-related problem, or another issue affecting normal cooling operation. The visible ice does not identify the cause by itself. A qualified HVAC technician can inspect the system and determine what needs attention.
When to arrange AC repair
Arrange Air Conditioning Repair if the unit repeatedly freezes, the home is not cooling normally, water is appearing around the indoor equipment, or the system stops operating as expected. Seek prompt professional help for unusual electrical smells, visible damage, or water near electrical components. Do not open electrical panels, handle refrigerant, enter an unsafe attic or crawlspace, or dismantle the AC equipment.
Use the AC repair service path
Air Conditioning Repair is the relevant service for an AC unit that is freezing up. Before contacting a company, record when the freezing started, whether it has happened before, what parts of the system show ice, and any changes in airflow or water around the equipment. Then use the Air Conditioning Repair page to review verified providers that can assess the system.
