It’s that time of year 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 fall heating tune-up, there are some problems that need to be examined. A serious problem you may run into is your furnace making funny noises – check out these furnace noises you should never disregard.
If you hear a loud scraping sound that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear a noise like this, shut off your furnace right away and call Service Experts Heating & Air Conditioning to inspect the equipment. There are multiple things that could be wrong with the blower wheel. First, it might just be loose and if the piece is not too impaired, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount is what broke, causing the whole blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the quiet and cozy home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace turns on, there are a few things that could be happening. Two general things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud booms after the heating blower turns on. A filthy furnace burner or ignitor could prevent the burners from igniting, resulting in gas to build up. When the gas finally does ignite, it will create the loud boom you hear. This could end up being a safety issue, especially if one of these small explosions caused the heat exchanger to crack. Not only could that produce a carbon monoxide leak, but you will have to replace the heat exchanger, which could be very expensive.
The other trouble, extending and contracting air ducts, is a common noise complaint for homes with metal ducts. If your equipment is making the loud bang and it is caused by your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to visit your home to diagnose your problem and get your home back in working order. Also, this will also result in improved comfort as well.
If you hear a squealing disturbance, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. An annual furnace tune-up will help discover these issues before they become big problems so make sure you give us a call at 352-414-4006 and we’ll make sure your heating system is ready to keep you safe and warm all winter long.
