HVAC Troubleshooting

Possible cause: Your circuit breaker tripped
Solution: Turn off your HVAC system, find the circuit breaker, and reset the system by flipping the switch off and back on.

Possible cause: Your thermostat is set incorrectly.
Solution: Lower the temperature on your thermostat, then wait to see if you feel a change. Or, try turning the thermostat off and back on, then resetting the temperature.
