It’s that time of year when homeowners start turning on their heaters to settle in for a frigid winter. Unfortunately, when some furnaces start up, especially if it hasn’t had a fall heating tune-up, there are some troubles that need to be examined. A serious problem you may encounter is your furnace making funny noises – read about these furnace noises you should never ignore.
If you hear a loud raking noise that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear a sound like this, power off your furnace immediately and call Service Experts Home Services by Enercare to inspect the furnace. There are multiple things that could be amiss with the blower wheel. First, it might just be loose and if the piece 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 is what broke, causing the complete blower assembly to shake uncontrollably. One of our service professionals would be happy to come out and take a look, and get you back to the silent and comfortable home you have come to love.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace turns on, there are a couple things that could be occurring. Two common problems are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud booms after the furnace blower comes on. A dirty furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas finally ignites, it will create the loud boom 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 may be very expensive.
The other problem, extending and contracting air ducts, is a common noise complaint for homes with metal ducts. If your furnace is making the loud bang and it is caused by your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Service Experts Home Services by Enercare is happy to visit your home to diagnose your problem and get your home back in working order. Ultimately, this will also give you improved comfort as well.
If you hear a squealing noise, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. An annual system tune-up will help discover these issues before they become big problems so make sure you call us at 613-817-1591 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
