Now is when people start turning on their heating systems to settle in for a cold winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some issues that need to be assessed. A serious problem you may run into is your furnace making funny noises – check out these furnace noises you should never ignore.
If you hear a loud scratching sound that sounds like metal on metal, there is possibly something defective with the blower wheel. If you hear something like this, shut off your furnace right away and call Roland J. Down Service Experts to inspect the system. There are multiple things that could be wrong with the blower wheel. First, it may just be loose and if the piece is not too impaired, can be tightened. Second, it might be that the blower wheel is broken and will require replacement. Or third, it could be that the motor mount actually broke, causing the entire blower assembly to shake uncontrollably. One of our service experts would be happy to come out and take a look, and get you back to the silent and cozy home you have come to love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace turns on, there are a few things that could be going on. Two general issues are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also create loud bangs after the furnace blower comes on. A dirty furnace burner or ignitor could holdup the burners from igniting, causing gas to build up. When the gas finally does ignite, it will create the loud boom you hear. This could cause a safety issue, especially if one of the small explosions caused the heat exchanger to crack. Not only could that cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very expensive.
The other problem, extending and contracting air ducts, is a common noise complaint for homes with metal ducts. If your system is making the loud boom and it is produced by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Roland J. Down Service Experts is happy to visit your home to diagnose your trouble and get your home back in working order. Additionally, this will also give you improved comfort as well.
If you hear a squealing noise, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A routine heating tune-up will help find these issues before they become major problems so make sure you call us at 518-417-2938 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
