Why Your Furnace May Be Making These Noises

November 23, 2016

This is the time of year homeowners start turning on their furnaces to settle in for a long winter. Unfortunately, when some heating systems start up, especially if it hasn’t had a fall heating tune-up, there are some troubles that need to be examined. A big problem you may discover is your furnace making weird noises – check out these furnace noises you should never ignore.

Scraping Sound

If you hear a loud scraping racket that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear something like this, shut off your furnace immediately and call Winnipeg Supply Service Experts to inspect the furnace. There are a few things that could be faulty with the blower wheel. First, it might just be loose and if the piece is not too damaged, 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 itself broke, causing the whole blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come to your home and take a look, and get you back to the quiet and cozy home you have come to adore.

Loud Bang When Furnace Starts

If there is a loud pop when your furnace kicks on, there are a handful of things that could be going on. Two general issues are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud noises after the furnace blower comes on. A soiled furnace burner or ignitor could holdup the burners from igniting, forcing gas to build up. When the gas finally ignites, 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 result in a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very costly.

The other problem, stretching and contracting air ducts, is a usual noise complaint for people with metal ducts. If your equipment is making the loud boom and it is caused by your air ducts, it could be an indication of undersized ducts, blocked vents, or a clogged air filter. Winnipeg Supply Service Experts is happy to come out to diagnose your problem and get your home back to order. Also, this will also give you improved comfort as well.

Whining Noise

If you hear a squealing 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.
