Why Your Furnace May Be Making These Noises
Now is when families start turning on their furnaces to settle in for a long winter. Unfortunately, when some heaters start up, especially if it hasn’t received a seasonal heating tune-up, there are some problems that need to be examined. A serious problem you may encounter is your furnace making funny noises – take a look at these furnace noises you should never disregard.
If you hear a loud scraping sound that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear something like this, shut off your furnace right away and call Wesley Wood Service Experts to inspect the system. There are a few things that could be wrong with the blower wheel. First, it could 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 will require replacement. Or third, it could 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 quiet and comfortable home you have come to love.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace comes on, there are a few things that could be happening. Two general issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud noises after the heating blower turns on. A dirty furnace burner or ignitor could delay the burners from igniting, resulting in 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 the small explosions caused the heat exchanger to crack. Not only could that cause a carbon monoxide leak, but you will have to replace the heat exchanger, which can be very expensive.
The other problem, stretching and contracting air ducts, is a common noise complaint for homeowners with metal ducts. If your equipment is making the loud bang and it is caused by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Wesley Wood Service Experts is happy to come out to diagnose your problem and get your home back to order. Additionally, this will also give you improved comfort as well.
If you hear a squealing sound, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A seasonal furnace tune-up will help find these issues before they become serious problems so make sure you call us at 484-401-7577 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
