Now is when people start turning on their furnaces to settle in for a long winter. Unfortunately, when some heaters start up, especially if it hasn’t had a fall heating tune-up, there are some issues that need to be assessed. A major problem you may run into is your furnace making unusual noises – check out these furnace noises you should never disregard.
If you hear a loud scraping sound that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear something like this, turn off your furnace immediately and call Service Experts Heating & Air Conditioning to inspect the equipment. There are multiple things that could be amiss with the blower wheel. First, it might just be loose and if the part is not too impaired, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount actually broke, causing the complete blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come over 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 boom when your furnace turns on, there are a few things that could be going on. Two common problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also create loud bangs after the furnace blower comes on. A filthy furnace burner or ignitor could prevent the burners from igniting, causing 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 the small explosions caused the heat exchanger to deteriorate. Not only could that result in a carbon monoxide leak, but you will have to replace the heat exchanger, which could be very expensive.
The other issue, stretching and contracting air ducts, is a typical noise complaint for people with metal ducts. If your furnace is making the loud boom and it is produced by your air ducts, it could be an indication of undersized ducts, obstructed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to visit your home to diagnose your trouble and get your home back in shape for the winter. Also, this will also give you improved comfort as well.
If you hear a high-pitched noise, 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 catch these issues before they become major problems so make sure you contact us at 866-397-3787 and we’ll make sure your heating equipment is ready to keep you safe and cozy all winter long.
