Try These Steps before You Call
Before you call, here is a brief list of items you can check before calling a service technician. This can save a trip to your house and a bill!
- Check the settings on your thermostat. Make sure the temperature set point is proper for the mode of operation, and the system switch is set for the proper mode "Heat," "Cool," or "Auto". If the fan will not shut off, make sure the fan switch is set to the "Auto" position.
- If the air flow out of the supply registers seems low, check the air filter.
- Make sure all the registers are open and not obstructed.
- Check the power disconnect and the breaker.
