It’s that time of year when families start turning on their furnaces to settle in for a long winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a fall heating tune-up, there are some problems that need to be examined. A serious problem you may run into is your furnace making weird noises – check out these furnace noises you should never neglect.
If you hear a loud scraping sound that sounds like metal on metal, there is possibly something defective with the blower wheel. If you hear a noise like this, power off your furnace ASAP and call Midland Air Service Experts to inspect the system. There are multiple things that could be wrong with the blower wheel. First, it may just be loose and if the piece is not too impaired, can be tightened. Second, it might be that the blower wheel is broken and needs to be replaced. Or third, it might be that the motor mount is what broke, causing the entire blower assembly to shake uncontrollably. One of our service technicians would be happy to come over and take a look, and get you back to the noiseless and warm home you have come to love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a couple things that could be occurring. Two common things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also cause loud noises after the heating blower turns on. A soiled 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 end up being a safety issue, especially if one of the small explosions caused the heat exchanger to deteriorate. Not only could that produce a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which can be very costly.
The other trouble, stretching and contracting air ducts, is a usual noise complaint for homes with metal ducts. If your system is making the loud bang and it is a result of your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. Midland Air Service Experts is happy to set up an appointment 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 motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A routine heating tune-up will help catch these issues before they become serious problems so make sure you give us a call at 803-399-7208 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
