Now is when people start turning on their furnaces 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 examined. A big problem you may discover is your furnace making unusual noises – check out these furnace noises you should never ignore.
If you hear a loud raking noise that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear a noise like this, shut off your furnace ASAP and call Rob's Albertan Service Experts to inspect the equipment. There are multiple things that could be amiss with the blower wheel. First, it could just be loose and if the piece is not too damaged, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount itself broke, causing the complete blower assembly to rattle 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 love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace kicks on, there are a few things that could be going on. Two general issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud bangs after the furnace blower comes on. A filthy furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas finally does ignite, it will create the loud bang you hear. This could cause 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 would also have to replace the heat exchanger, which can be very expensive.
The other problem, 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 produced by your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Rob's Albertan Service Experts is happy to come out to diagnose your trouble and get your home back in working order. Also, this will also result in improved comfort as well.
If you hear a whining noise, 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. A seasonal system tune-up will help discover these issues before they become major problems so make sure you contact us at 780-800-9047 and we’ll make sure your heating equipment is ready to keep you safe and cozy all winter long.
