What this usually means
Confirm the thermostat has power and is set to COOL. Check the labeled HVAC breaker once, but do not repeatedly reset a breaker that trips.
Many systems include a switch that stops cooling when condensate cannot drain safely. Finding water near the indoor unit is useful information for the technician.
What you can safely check
- Thermostat display and mode
- HVAC breaker position
- Indoor service switch
- Visible water near the indoor unit
When to call a professional
Request service when power and thermostat settings appear normal, or immediately for sparking, burning odor or a breaker that trips again.
