Why Your Furnace May Be Making These Noises

Now is when homeowners start turning on their heaters to settle in for a long winter. Unfortunately, when some furnaces start up, especially if it hasn’t had a yearly heating tune-up, there are some troubles that need to be inspected. A major problem you may discover is your furnace making funny noises – read about these furnace noises you should never disregard.

Scraping Sound

If you hear a loud raking noise that sounds like metal on metal, there is possibly something faulty with the blower wheel. If you hear a noise 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 wrong with the blower wheel. First, it might just be loose and if the piece is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and in need of replacement. Or third, it might be that the motor mount actually broke, causing the whole blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the noiseless and cozy home you have come to love.

Loud Bang When Furnace Starts

If there is a loud pop when your furnace kicks on, there are a few things that could be occurring. Two typical things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud booms after the heating system blower comes on. A soiled furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas finally does ignite, it will create the loud boom you hear. This could result in a safety issue, especially if one of those small explosions caused the heat exchanger to deteriorate. Not only could that produce a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very expensive.

The other trouble, expanding and contracting air ducts, is a common noise complaint for people with metal ducts. If your equipment is making the loud boom and it is a result of your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Winnipeg Supply Service Experts is happy to visit your home to diagnose your problem and get your home back to order. Ultimately, this will also provide improved comfort as well.

Whining Noise

If you hear a high-pitched sound, 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.
