Now is when families start turning on their heaters to settle in for a frigid winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some issues that need to be examined. A major problem you may discover is your furnace making weird noises – read about these furnace noises you should never neglect.
Scraping Sound
If you hear a loud scratching racket that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear a noise like this, turn off your furnace right away and call Service Experts Heating & Air Conditioning to inspect the furnace. There are a few 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 in need of replacement. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to shake uncontrollably. One of our service professionals would be happy to come out and take a look, and get you back to the noiseless and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace turns on, there are a few things that could be occurring. Two typical problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud sounds 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 finally ignites, it will create the loud pop 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 cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which can be very expensive.
The other problem, stretching and contracting air ducts, is a typical noise complaint for people with metal ducts. If your equipment is making the loud bang and it is produced by your air ducts, it could be an indication 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 shape for the winter. Additionally, this will also result in improved comfort as well.
Whining Noise
If you hear a high-pitched disturbance, it could be the shaft bearings are in need of oil, there is an issue with the blower belt, or the blower motor is malfunctioning.
