This is the time of year homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some furnaces start up, especially if it hasn’t received a seasonal heating tune-up, there are some issues that need to be examined. A serious problem you may run into is your furnace making unusual noises – take a look at these furnace noises you should never neglect.
If you hear a loud raking sound that sounds like metal on metal, there is possibly something faulty with the blower wheel. If you hear a noise like this, power off your furnace right away and call McElroy Service Experts to inspect the furnace. There are a couple things that could be amiss with the blower wheel. First, it might 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 might be that the motor mount actually broke, causing the whole blower assembly to shake uncontrollably. One of our service professionals would be happy to come to your home and take a look, and get you back to the noiseless and warm home you have come to love.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace kicks on, there are a handful of things that could be happening. Two common issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud bangs after the heating system blower starts up. A filthy furnace burner or ignitor could prevent the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud pop you hear. This could end up being a safety issue, especially if one of the small explosions caused the heat exchanger to break. 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 issue, expanding and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your equipment is making the loud pop and it is a result of your air ducts, it could be a sign of undersized ducts, closed vents, or a clogged air filter. McElroy Service Experts is happy to visit your home to diagnose your trouble and get your home back in working order. Also, this will also provide improved comfort as well.
If you hear a whining disturbance, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A seasonal system tune-up will help catch these issues before they become big problems so make sure you contact us at 308-210-4398 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
