It’s that time of year when homeowners 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 fall heating tune-up, there are some issues that need to be examined. A big problem you may discover is your furnace making unusual noises – check out these furnace noises you should never ignore.
If you hear a loud scraping sound 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 furnace. There are multiple things that could be amiss with the blower wheel. First, it could just be loose and if the piece is not too harmed, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to shake uncontrollably. One of our service professionals would be happy to come out and take a look, and get you back to the noiseless and cozy 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 few things that could be going on. Two general problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud noises after the furnace blower comes on. A dirty furnace burner or ignitor could delay the burners from igniting, causing gas to build up. When the gas does finally ignite, 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 break. Not only could that result in a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which can be very pricey.
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 pop and it is a result of 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 visit your home to diagnose your problem and get your home back in shape for the winter. Also, this will also result in improved comfort as well.
If you hear a whining sound, 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. A seasonal furnace tune-up will help find these issues before they become big problems so make sure you contact us at 904-450-5672 and we’ll make sure your heating system is ready to keep you safe and warm all winter long.
