Helpful Furnace Tips

Markham Heating would love to come to see you but before you make the call there are a few important things you can investigate:

  • Check to make sure thermostat is set correctly and batteries are OK.
  • Check furnace or air filter and make sure it is not excessively dirty or plugged.
  • Check to make sure the furnace switch and breaker are turned on.
  • Try turning the furnace switch off and on at the switch in the furnace room; this will reset the furnaces electronic controls. Allow five minutes for it to restart.
  • On high-efficiency gas furnaces, make sure your intake and exhaust pipes are clear of snow and ice.
  • Ensure both your furnace doors are on correctly.


Still no luck? Give us a call and we'll be over as soon as possible!
