It’s that time of year when homeowners start turning on their furnaces to settle in for a long winter. Unfortunately, when some heaters start up, especially if it hasn’t undergone a fall heating tune-up, there are some problems that need to be examined. A serious problem you may encounter is your furnace making unusual noises – check out these furnace noises you should never ignore.
If you hear a loud scratching racket that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear something like this, turn off your furnace ASAP and call Levy & Son Service Experts to inspect the system. There are multiple things that could be amiss with the blower wheel. First, it may just be loose and if the component is not too impaired, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it may be that the motor mount itself broke, causing the whole blower assembly to rattle uncontrollably. One of our service experts would be happy to come out and take a look, and get you back to the noiseless and comfortable home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a handful of things that could be going on. Two common things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also produce loud sounds after the furnace blower comes on. A soiled furnace burner or ignitor could holdup the burners from igniting, causing gas to build up. When the gas finally ignites, it will create the loud bang you hear. This could cause a safety issue, especially if one of those 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 may be very expensive.
The other trouble, expanding and contracting air ducts, is a common noise complaint for homes with metal ducts. If your furnace is making the loud bang and it is caused by your air ducts, it could be an indication of undersized ducts, obstructed vents, or a clogged air filter. Levy & Son Service Experts is happy to visit your home to diagnose your problem and get your home back to order. Additionally, this will also give you improved comfort as well.
If you hear a squealing disturbance, 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 routine furnace tune-up will help catch these issues before they become big problems so make sure you call us at 469-250-0932 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
