This is the time of year people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some troubles that need to be examined. A big problem you may run into is your furnace making unusual noises – read about these furnace noises you should never ignore.
If you hear a loud scraping 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 Neal Harris Service Experts to inspect the equipment. There are multiple things that could be wrong with the blower wheel. First, it could just be loose and if the part 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 is what broke, causing the whole blower assembly to shake uncontrollably. One of our service technicians would be happy to come over and take a look, and get you back to the silent and comfortable home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a handful of things that could be happening. Two typical issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also cause loud noises after the heating blower turns on. A soiled furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to crack. Not only could that cause a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very expensive.
The other issue, stretching and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your furnace is making the loud pop and it is a result of your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Neal Harris Service Experts is happy to come out to diagnose your problem and get your home back in working order. Also, this will also provide improved comfort as well.
If you hear a whining sound, 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. An annual heating tune-up will help discover these issues before they become big problems so make sure you give us a call at 816-787-0500 and we’ll make sure your heating equipment is ready to keep you safe and cozy all winter long.
