How often should I change my furnace filter?

Depending on the size of your furnace filter and the usage of your furnace, you should change the filters around every 1-3 months.

Why is my furnace making weird noises?

  • If you hear scraping noises, something is likely loose and needs to be fixed immediately
  • If you hear popping or banging noises, it could mean you have dirty furnace burners or the air ducts are expanding and contracting
  • If you hear squealing noises, it generally means a part needs to be replaced or fixed

Why does my heating bill keep going up?

  • You have older appliances in your house
  • You’ve started using more new appliances
