If the AC Stops Cooling

1. Check the thermostat settings and batteries.
2. Make sure the outdoor unit has power and is not blocked.
3. Replace a dirty air filter.
4. Turn the system off if you hear grinding or smell burning.

If the Heat Stops Working

2. Check the furnace switch and circuit breaker.
3. Look at the pilot light or ignition (if accessible and safe).
4. Keep space heaters away from flammable materials.
