This is the time of year people start turning on their heating systems to settle in for a cold winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a yearly heating tune-up, there are some issues that need to be inspected. A major problem you may discover is your furnace making funny noises – read about these furnace noises you should never disregard.
If you hear a loud raking sound that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear something like this, power off your furnace ASAP and call Becht/Givens Service Experts to inspect the equipment. There are a couple things that could be wrong with the blower wheel. First, it might just be loose and if the component is not too harmed, can be tightened. Second, it might be that the blower wheel is broken and will require replacement. Or third, it might be that the motor mount itself broke, causing the whole 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 quiet 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 going on. Two general problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud booms after the heating system blower starts up. A soiled furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas finally does ignite, it will create the loud pop you hear. This could end up being 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’d end up having to replace the heat exchanger, which could be very costly.
The other problem, stretching and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your system is making the loud pop and it is caused by your air ducts, it could be a sign of undersized ducts, obstructed vents, or a clogged air filter. Becht/Givens Service Experts is happy to visit your home 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 sound, 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.
