When your furnace is running during cold weather, you have a good idea of what kind of noises it makes. A modern furnace won’t make a racket, but it does create a blanket white noise of air moving through the vents. When you’re near to the HVAC cabinet, you’ll be able to hear the burners running and the noise of the blower fan and its motor.
But if your furnace is making unusual sounds, ones you aren’t accustomed to hearing, you may feel worried something is wrong. Is it an emergency that needs 24/7 services from a Smyrna, DE, HVAC contractor? Or is it maybe nothing and you’re overreacting?
