Why Your Furnace May Be Making These Noises

This is the time of year people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a seasonal heating tune-up, there are some problems that need to be assessed. A big problem you may discover 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 likely something faulty with the blower wheel. If you hear something like this, turn off your furnace right away 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 harmed, can be tightened. Second, it could be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount is what broke, causing the whole blower assembly to shake uncontrollably. One of our service experts 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 love. 

Loud Bang When Furnace Starts 

If there is a loud bang when your furnace turns on, there are a few things that could be going on. Two general things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud sounds after the heating blower turns on. A filthy furnace burner or ignitor could prevent the burners from igniting, resulting in gas to build up. When the gas finally ignites, it will create the loud pop you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to break. Not only could that result in a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very pricey. 

The other problem, extending and contracting air ducts, is a common noise complaint for homes with metal ducts. If your equipment is making the loud bang and it is caused by your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Winnipeg Supply Service Experts is happy to visit your home to diagnose your trouble and get your home back in shape for the winter. Ultimately, this will also give you improved comfort as well.
