It’s that time of year when families start turning on their furnaces to settle in for a long 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 inspected. A major problem you may discover is your furnace making unusual noises – check out these furnace noises you should never disregard.
If you hear a loud raking sound that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a sound like this, turn off your furnace ASAP and call Service Experts Heating & Air Conditioning to inspect the system. There are multiple things that could be amiss with the blower wheel. First, it could just be loose and if the component is not too damaged, can be tightened. Second, it could 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 to your home and take a look, and get you back to the silent and cozy 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 few things that could be occurring. Two common problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud booms after the furnace blower comes on. A filthy 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 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 pricey.
The other problem, extending and contracting air ducts, is a common noise complaint for homes with metal ducts. If your equipment 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 visit your home to diagnose your problem and get your home back in shape for the winter. Ultimately, this will also provide 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.
