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 fall heating tune-up, there are some troubles that need to be inspected. A major problem you may encounter is your furnace making unusual noises – check out these furnace noises you should never neglect.
If you hear a loud scraping sound that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a noise like this, turn off your furnace right away and call Boehmers/Cronin Emery Home Services by Enercare to inspect the furnace. There are a couple 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 could 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 shake uncontrollably. One of our service experts would be happy to come out and take a look, and get you back to the noiseless and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a few things that could be occurring. Two common things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud sounds after the furnace blower comes on. A soiled 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 boom you hear. This could result in a safety issue, especially if one of the 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 expensive.
The other problem, extending and contracting air ducts, is a usual noise complaint for homes with metal ducts. If your equipment is making the loud bang and it is caused by your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. Boehmers/Cronin Emery Home Services by Enercare is happy to set up an appointment to diagnose your trouble and get your home back in shape for the winter. Ultimately, this will also give you improved comfort as well.
If you hear a whining disturbance, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A routine system tune-up will help catch these issues before they become serious problems so make sure you call us at 519-804-1617 and we’ll make sure your heating system is ready to keep you safe and warm all winter long.
