Now is when families start turning on their heating systems to settle in for a cold winter. Unfortunately, when some furnaces start up, especially if it hasn’t received a yearly heating tune-up, there are some troubles that need to be assessed. A big problem you may discover is your furnace making unusual noises – read about these furnace noises you should never ignore.
If you hear a loud scraping racket that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear something like this, power off your furnace ASAP and call Service Experts Heating & Air Conditioning 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 part 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 could be that the motor mount is what broke, causing the complete blower assembly to shake uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the silent and comfortable home you have come to love.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace turns on, there are a few things that could be happening. Two typical things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also cause loud booms after the furnace blower comes on. A soiled furnace burner or ignitor could delay 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 result in a safety issue, especially if one of those 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 can be very pricey.
The other trouble, expanding and contracting air ducts, is a typical noise complaint for people with metal ducts. If your system is making the loud boom and it is a result of your air ducts, it could be a symptom of undersized ducts, obstructed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your trouble and get your home back in shape for the winter. Also, this will also provide improved comfort as well.
If you hear a high-pitched sound, 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 give us a call at 239-908-6991 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
