Now is when homeowners start turning on their furnaces to settle in for a long winter. Unfortunately, when some heaters start up, especially if it hasn’t received a seasonal heating tune-up, there are some troubles that need to be inspected. A serious problem you may discover is your furnace making funny noises – take a look at these furnace noises you should never disregard.
If you hear a loud scratching sound that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear a noise like this, turn off your furnace right away and call Golden Seal Service Experts Heating & Air Conditioning to inspect the equipment. There are a couple 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 may be that the blower wheel is broken and will require replacement. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to rattle uncontrollably. One of our service technicians would be happy to come to your home and take a look, and get you back to the noiseless and comfortable home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace turns on, there are a handful of things that could be happening. Two general problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud bangs after the heating system blower starts up. A filthy furnace burner or ignitor could prevent the burners from igniting, causing gas to build up. When the gas finally does ignite, it will create the loud bang you hear. This could result in a safety issue, especially if one of those small explosions caused the heat exchanger to crack. Not only could that result in a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very costly.
The other issue, expanding and contracting air ducts, is a common noise complaint for people with metal ducts. If your furnace is making the loud bang and it is caused by your air ducts, it could be a sign of undersized ducts, closed vents, or a clogged air filter. Golden Seal Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your issue and get your home back in working order. Ultimately, this will also result in improved comfort as well.
If you hear a whining 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 catch these issues before they become major problems so make sure you call us at 630-246-2698 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
