This is the time of year people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a seasonal heating tune-up, there are some issues that need to be examined. A big problem you may discover is your furnace making unusual noises – take a look at these furnace noises you should never ignore.
If you hear a loud raking noise that sounds like metal on metal, there is possibly something faulty with the blower wheel. If you hear something like this, turn off your furnace immediately and call Air Engineers Service Experts to inspect the system. There are multiple things that could be amiss with the blower wheel. First, it may just be loose and if the piece is not too harmed, can be tightened. Second, it could be that the blower wheel is broken and needs to be replaced. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come out and take a look, and get you back to the noiseless and warm home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a couple things that could be going on. Two general problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud noises after the heating blower turns on. A dirty furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to break. Not only could that cause a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very expensive.
The other problem, stretching and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your system is making the loud bang and it is caused by your air ducts, it could be a symptom of undersized ducts, obstructed vents, or a clogged air filter. Air Engineers Service Experts is happy to come out to diagnose your problem and get your home back in shape for the winter. Also, this will also provide improved comfort as well.
If you hear a squealing noise, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A seasonal furnace tune-up will help find these issues before they become major problems so make sure you give us a call at 904-450-5672 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
