HVAC Emergency: What to Do While Waiting for Help
When your AC or furnace fails unexpectedly, staying calm and taking appropriate steps matters. Here's your emergency guide.
HVAC failures during uncomfortable weather create real stress. Knowing what to do while waiting for professional help keeps your family comfortable and prevents additional damage.
When AC Won't Cool
**Check Thermostat** Verify correct settings. Try lowering temperature five degrees. Replace batteries if display is dim.
**Check Circuit Breaker** Locate HVAC breaker and check for trips. Reset if needed. If it trips again immediately, leave it off.
**Inspect Filter** Severely clogged filters can cause shutdown. Replace if dirty and attempt restart.
**Examine Outdoor Unit** Look for obvious issues: debris blocking airflow, ice on lines, standing water around the unit.
When Furnace Won't Heat
**Verify Thermostat** Confirm "heat" mode and temperature above current room temperature.
**Check Gas Supply** Gas valve handle should align with the pipe (open position).
**Check Breaker** Gas furnaces require electricity for controls and blowers.
**Look for Error Codes** Many furnaces have LED lights that flash diagnostic codes.
