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 had a fall heating tune-up, there are some issues that need to be assessed. A big problem you may encounter is your furnace making unusual noises – read about these furnace noises you should never disregard.
If you hear a loud scraping racket 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 immediately and call Epperson Service Experts Heating & Air Conditioning to inspect the system. There are a couple things that could be faulty with the blower wheel. First, it may 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 could 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 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 boom when your furnace kicks on, there are a few things that could be occurring. Two typical problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce 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 finally does ignite, 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 deteriorate. Not only could that produce a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very expensive.
The other problem, expanding and contracting air ducts, is a usual noise complaint for people 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, obstructed vents, or a clogged air filter. Epperson Service Experts Heating & Air Conditioning is happy to set up an appointment 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 system tune-up will help catch these issues before they become big problems so make sure you give us a call at 843-619-3781 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
