This is the time of year families 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 undergone a fall heating tune-up, there are some problems that need to be assessed. A major problem you may discover is your furnace making unusual noises – check out these furnace noises you should never ignore.
If you hear a loud scraping noise that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a noise like this, shut off your furnace ASAP and call Service Experts Heating & Air Conditioning to inspect the furnace. There are multiple things that could be amiss 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 is what broke, causing the whole blower assembly to rattle uncontrollably. One of our service technicians would be happy to come out and take a look, and get you back to the quiet and warm home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a couple things that could be occurring. Two typical problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also produce loud sounds after the furnace blower comes on. A dirty furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas finally ignites, it will create the loud boom you hear. This could cause 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 would also have to replace the heat exchanger, which may be very expensive.
The other problem, extending 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 produced by your air ducts, it could be a symptom of undersized ducts, obstructed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to come out to diagnose your issue and get your home back in shape for the winter. Additionally, this will also result in improved comfort as well.
If you hear a whining disturbance, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A seasonal system tune-up will help discover these issues before they become major problems so make sure you call us at 289-273-2229 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
