Why Your Furnace May Be Making These Noises
It’s that time of year when people start turning on their heating systems to settle in for a long winter. Unfortunately, when some heaters start up, especially if it hasn’t undergone a fall heating tune-up, there are some problems that need to be assessed. A major problem you may encounter is your furnace making weird noises – check out these furnace noises you should never disregard.
Scraping Sound
If you hear a loud scratching sound that sounds like metal on metal, there is possibly something defective with the blower wheel. If you hear something like this, turn off your furnace immediately and call Stevenson Service Experts to inspect the equipment. There are multiple things that could be faulty with the blower wheel. First, it may just be loose and if the piece is not too harmed, can be tightened. Second, it might be that the blower wheel is broken and needs to be replaced. Or third, it might be that the motor mount actually broke, causing the complete blower assembly to rattle uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the silent and warm home you have come to love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a few things that could be going on. Two common things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud sounds after the furnace blower comes on. A soiled furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could end up being a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very pricey.
The other problem, stretching and contracting air ducts, is a typical noise complaint for people with metal ducts. If your equipment is making the loud pop and it is produced by your air ducts, it could be a symptom of undersized ducts, obstructed vents, or a clogged air filter. Stevenson Service Experts is happy to visit your home to diagnose your problem and get your home back in working order. Ultimately, this will also result in improved comfort as well.
Whining Noise
If you hear a whining disturbance, it could be the shaft bearings are in need of oil, there is an issue with the blower belt, or the blower motor is malfunctioning.
