It’s that time of year when homeowners 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 problems that need to be examined. A major problem you may run into is your furnace making unusual noises – read about these furnace noises you should never neglect.
If you hear a loud scraping noise that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear something like this, power off your furnace immediately and call Peachtree Service Experts Heating & Air Conditioning to inspect the equipment. There are multiple things that could be amiss with the blower wheel. First, it may just be loose and if the piece is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and needs to be replaced. Or third, it might be that the motor mount itself broke, causing the entire 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 warm 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 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 soiled furnace burner or ignitor could delay the burners from igniting, forcing gas to build up. When the gas finally does ignite, it will create the loud bang you hear. This could end up being a safety issue, especially if one of the small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you will have to replace the heat exchanger, which can be very costly.
The other problem, extending and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your equipment is making the loud pop and it is produced by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Peachtree Service Experts Heating & Air Conditioning is happy to come out to diagnose your issue and get your home back to order. Ultimately, this will also give you 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 system tune-up will help catch these issues before they become big problems so make sure you call us at 678-235-9699 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
