It’s that time of year when families start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heaters start up, especially if it hasn’t received a yearly heating tune-up, there are some problems that need to be examined. A serious problem you may discover is your furnace making weird noises – check out these furnace noises you should never disregard.
If you hear a loud scratching noise that sounds like metal on metal, there is possibly something faulty with the blower wheel. If you hear a sound like this, turn off your furnace right away and call Stevenson Service Experts Heating & Air Conditioning to inspect the furnace. There are multiple 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 might be that the blower wheel is broken and in need of replacement. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to shake uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the silent and warm home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a handful of things that could be going on. Two general things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also produce loud booms after the furnace blower comes on. A soiled furnace burner or ignitor could prevent the burners from igniting, causing gas to build up. When the gas finally does ignite, 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’d end up having to replace the heat exchanger, which could be very expensive.
The other issue, stretching and contracting air ducts, is a common noise complaint for homeowners with metal ducts. If your system is making the loud boom and it is caused by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Stevenson Service Experts Heating & Air Conditioning is happy to come out to diagnose your issue and get your home back in working order. Additionally, this will also provide improved comfort as well.
If you hear a high-pitched 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 heating tune-up will help find these issues before they become serious problems so make sure you call us at 937-503-7896 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
