This is the time of year families start turning on their furnaces to settle in for a frigid winter. Unfortunately, when some furnaces start up, especially if it hasn’t received a yearly heating tune-up, there are some issues that need to be inspected. A major problem you may encounter is your furnace making unusual noises – take a look at these furnace noises you should never ignore.
If you hear a loud scraping noise that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear a sound like this, power off your furnace immediately and call Midway Services to inspect the furnace. There are a few things that could be wrong with the blower wheel. First, it could just be loose and if the piece is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and needs to be replaced. Or third, it could be that the motor mount actually broke, causing the whole blower assembly to rattle uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the quiet and warm home you have come to love.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace turns on, there are a couple things that could be going on. Two general things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud bangs after the furnace blower comes on. A filthy furnace burner or ignitor could delay the burners from igniting, causing gas to build up. When the gas finally does ignite, it will create the loud bang you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to crack. Not only could that produce a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very costly.
The other issue, expanding and contracting air ducts, is a common noise complaint for homeowners with metal ducts. If your equipment is making the loud pop and it is caused by your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Midway Services is happy to come out to diagnose your issue and get your home back to order. Additionally, this will also result in improved comfort as well.
If you hear a high-pitched noise, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A seasonal heating tune-up will help catch these issues before they become big problems so make sure you call us at 727-219-2471 and we’ll make sure your furnace is ready to keep you safe and warm all winter long.
