This is the time of year homeowners start turning on their furnaces to settle in for a long winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some problems that need to be examined. A big problem you may run into is your furnace making unusual noises – take a look at these furnace noises you should never neglect.
If you hear a loud raking sound that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear a noise like this, turn off your furnace immediately and call Abbey Air Home Services by Enercare to inspect the system. There are a couple things that could be wrong 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 needs to be replaced. Or third, it may be that the motor mount is what broke, causing the whole blower assembly to rattle uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the noiseless and warm home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a couple things that could be occurring. Two typical things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also cause loud noises after the furnace blower comes on. A dirty furnace burner or ignitor could holdup the burners from igniting, causing gas to build up. When the gas finally ignites, it will create the loud boom 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 will have to replace the heat exchanger, which could be very pricey.
The other issue, extending and contracting air ducts, is a usual noise complaint for people with metal ducts. If your equipment is making the loud pop and it is caused by your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Abbey Air Home Services by Enercare is happy to come out to diagnose your trouble and get your home back in shape for the winter. Ultimately, this will also result in improved comfort as well.
If you hear a squealing disturbance, 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. An annual system tune-up will help find these issues before they become major problems so make sure you give us a call at 289-813-5566 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
