Emergency AC repair: what to do first
When your AC stops in Texas heat: check the thermostat (Cool, set lower), the breakers, and the air filter. If the outdoor unit is iced, turn cooling off and run the fan to thaw. Move vulnerable people somewhere cool, then call a licensed HVAC pro. Leave immediately and call 911 if you smell gas or a CO alarm sounds.
Quick checks
- Thermostat: Cool mode, set below room temperature, fresh batteries.
- Breakers: reset a tripped breaker once; if it trips again, stop and call a pro.
- Filter: replace if dirty.
- Outdoor unit: clear debris; don't open the panel.
- Condensate: some systems shut off when the drain pan is full.
Stay cool while you wait
- Close blinds, use fans, drink water.
- Check on older adults, babies and pets.
- Go to a cooled public place if the home gets dangerously hot. See NWS heat safety.
When calling
Tell the dispatcher the system type and age, what you've checked, and any sounds or ice. Ask about the service-call fee and after-hours rates upfront.

Questions
Should I keep running my AC if it's frozen?
No. Turn off cooling and run the fan to thaw it, then fix the airflow issue or call a pro.
