  • Your Furnace is Blowing Cold Air: The most common cause is a dirty flame sensor that needs cleaning. It could also be a problem with the pilot light or electronic ignition system, or an issue with the gas supply.
  • The Furnace Burner Flame is Yellow, Not Blue: A yellow or flickering burner flame is a serious safety concern. It often indicates dirty burners or a problem with the gas-to-air mixture, which can produce carbon monoxide. If you see this, turn off your furnace and call us immediately.
  • You Hear Strange Noises: A high-pitched squealing could mean a problem with the blower motor belt or bearings. A rattling noise might indicate loose panels or hardware. A loud booming or banging sound on startup could be a delayed ignition issue, which is dangerous and requires immediate professional attention.
