This is the time of year homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a fall heating tune-up, there are some problems that need to be inspected. A serious problem you may encounter is your furnace making weird noises – take a look at these furnace noises you should never neglect.
If you hear a loud scratching sound that sounds like metal on metal, there is possibly something faulty with the blower wheel. If you hear something like this, shut off your furnace immediately and call TML Service Experts to inspect the equipment. 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 might 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 whole blower assembly to shake uncontrollably. One of our service technicians would be happy to come out and take a look, and get you back to the noiseless and comfortable home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace kicks on, there are a couple things that could be happening. Two common problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud bangs after the furnace blower comes on. A soiled furnace burner or ignitor could delay the burners from igniting, causing gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could end up being a safety issue, especially if one of the small explosions caused the heat exchanger to crack. Not only could that produce a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very costly.
The other problem, stretching and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your system is making the loud boom and it is a result of your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. TML Service Experts is happy to set up an appointment to diagnose your problem and get your home back to order. Also, this will also give you improved comfort as well.
If you hear a squealing noise, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. An annual furnace tune-up will help catch these issues before they become major problems so make sure you give us a call at 208-488-4892 and we’ll make sure your heating system is ready to keep you safe and warm all winter long.
