Knowing if you need repair service on your furnace or AC can be daunting. Below are some tips to try that will save you money on a repair bill.

  1. Inspect the filter.

    Have you changed or cleaned your filter recently? A dirty filter is one of the most common reasons a furnace has problems and does not function properly. Dust and dirt restrict proper airflow through a furnace causing the heat exchanger to overheat and making it turn off.

  2. Check the thermostat. 

    Make sure your thermostat is set to heat.

  3. Change the batteries.

    Old batteries can cause a thermostat to stop functioning properly and revert to default programming.

  4. Verify temperature setting.

    Make sure the temperature is set higher than the current temperature in the room. 

  5. Test the thermostat.

    Set the temperature 10 degrees warmer then the temperature in the room to see if the furnace turns on.

  6. Check the circuit breaker.

    Make sure the circuit breaker isn’t tripped. A power outage or surge has not caused a breaker to trip.

  7. Inspect air ducts.

    Make sure vents are fully open and nothing is blocking proper air flow in the room.
