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 inspected. A major 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 defective with the blower wheel. If you hear a noise like this, turn off your furnace right away and call Climate Control Service Experts to inspect the equipment. There are a few things that could be wrong with the blower wheel. First, it could just be loose and if the component is not too impaired, can be tightened. Second, it might be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount actually broke, causing the complete 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 adore.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a few things that could be occurring. Two common issues are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud booms after the heating system blower starts up. A filthy furnace burner or ignitor could prevent 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 cause a safety issue, especially if one of those small explosions caused the heat exchanger to break. Not only could that produce a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very expensive.
The other trouble, 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, closed vents, or a clogged air filter. Climate Control Service Experts is happy to come out to diagnose your trouble and get your home back in working order. Also, this will also provide 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 furnace tune-up will help discover these issues before they become big 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 comfortable all winter long.
