This is the time of year families start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heaters start up, especially if it hasn’t undergone a fall heating tune-up, there are some issues that need to be assessed. A serious problem you may discover is your furnace making unusual noises – read about these furnace noises you should never disregard.
If you hear a loud scratching racket that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear a sound like this, shut off your furnace right away and call Climate Control Service Experts to inspect the equipment. There are a couple things that could be amiss with the blower wheel. First, it could just be loose and if the part is not too damaged, can be tightened. Second, it might be that the blower wheel is broken and needs to be replaced. Or third, it may be that the motor mount actually broke, causing the complete blower assembly to shake uncontrollably. One of our service professionals would be happy to come to your home 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 bang when your furnace comes on, there are a couple things that could be occurring. Two typical things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also cause loud sounds after the heating system blower starts up. A dirty furnace burner or ignitor could prevent 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 end up being a safety issue, especially if one of these small explosions caused the heat exchanger to break. Not only could that produce a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very expensive.
The other issue, stretching and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your furnace is making the loud boom and it is a result of your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Climate Control Service Experts is happy to come out to diagnose your trouble and get your home back to order. Also, this will also result in improved comfort as well.
If you hear a high-pitched noise, 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 discover these issues before they become major problems so make sure you call us at 251-202-7503 and we’ll make sure your furnace is ready to keep you safe and warm all winter long.
