When Your Heat Isn't Working

  • Make sure you have a clean filter installed.
  • Check your breaker panel.
  • Do you have a display on the thermostat? If not, you may need to change your batteries.
  • Are your exhaust & intake pipes clear outside? Make sure there is no snow blocking either of these.
