It’s that time of year when homeowners 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 seasonal heating tune-up, there are some problems that need to be examined. A big problem you may encounter is your furnace making unusual noises – check out these furnace noises you should never neglect.
If you hear a loud raking sound that sounds like metal on metal, there is possibly something defective with the blower wheel. If you hear a noise like this, shut off your furnace ASAP and call Abbey Air Service Experts Heating & Air Conditioning to inspect the system. There are a few things that could be wrong with the blower wheel. First, it could just be loose and if the part is not too damaged, can be tightened. Second, it may 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 complete 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 cozy home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace comes on, there are a few things that could be occurring. Two typical issues are a dirty furnace burner or ignitor. Expanding 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 break. Not only could that result in a carbon monoxide leak, but you will have to replace the heat exchanger, which could be very expensive.
The other issue, expanding and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your system is making the loud bang and it is a result of your air ducts, it could be a sign of undersized ducts, closed vents, or a clogged air filter. Abbey Air Service Experts Heating & Air Conditioning is happy to visit your home to diagnose your trouble and get your home back in shape for the winter. Ultimately, this will also provide 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 find these issues before they become big problems so make sure you give us a call at 289-813-5566 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
