Now is when families start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t had a yearly heating tune-up, there are some troubles that need to be assessed. A big problem you may run into is your furnace making weird noises – check out these furnace noises you should never disregard.
If you hear a loud raking sound that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear something like this, power off your furnace right away and call D.A. Bennett Service Experts Heating & Air Conditioning to inspect the system. There are a couple things that could be amiss with the blower wheel. First, it could just be loose and if the piece 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 could be that the motor mount itself broke, causing the complete blower assembly to shake uncontrollably. One of our service experts would be happy to come to your home and take a look, and get you back to the silent and cozy home you have come to love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace turns on, there are a handful of things that could be happening. Two general issues are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also create loud bangs after the heating system blower starts up. A soiled furnace burner or ignitor could holdup the burners from igniting, forcing gas to build up. When the gas finally ignites, it will create the loud bang you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you will have to replace the heat exchanger, which can be very pricey.
The other issue, stretching and contracting air ducts, is a common noise complaint for homeowners with metal ducts. If your furnace is making the loud bang and it is produced by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. D.A. Bennett Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your issue and get your home back in working order. Also, this will also provide improved comfort as well.
If you hear a whining sound, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt.
