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 fall heating tune-up, there are some problems that need to be examined. A serious problem you may encounter is your furnace making weird noises – take a look at these furnace noises you should never disregard.
If you hear a loud raking sound that sounds like metal on metal, there is likely something wrong with the blower wheel. If you hear something like this, shut off your furnace right away and call Wesley Wood Service Experts Heating & Air Conditioning to inspect the furnace. There are a few 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 might be that the blower wheel is broken and will require replacement. Or third, it may be that the motor mount actually broke, causing the whole blower assembly to shake uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the silent and comfortable home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a few things that could be happening. Two general things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also produce loud noises after the heating blower turns on. A filthy furnace burner or ignitor could delay the burners from igniting, causing gas to build up. When the gas does finally 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 pricey.
The other problem, stretching and contracting air ducts, is a typical 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, blocked vents, or a clogged air filter. Wesley Wood Service Experts Heating & Air Conditioning is happy to visit your home to diagnose your issue and get your home back to order. Additionally, this will also give you improved comfort as well.
If you hear a whining noise, it could be the shaft bearings are in need of oil, there is an issue with the blower belt, or the blower motor is malfunctioning. A seasonal heating tune-up will help catch these issues before they become serious problems so make sure you call us at 484-401-7577 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
