Now is when families start turning on their furnaces to settle in for a long winter. Unfortunately, when some heating systems start up, especially if it hasn’t had a yearly heating tune-up, there are some troubles that need to be assessed. A major problem you may run into is your furnace making funny noises – read about these furnace noises you should never disregard.
Scraping Sound
If you hear a loud raking sound that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear a sound like this, shut off your furnace immediately and call All American Air Service Experts to inspect the system. There are a couple things that could be amiss with the blower wheel. First, it might just be loose and if the component 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 could be that the motor mount is what broke, causing the whole blower assembly to shake uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the quiet and comfortable home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace turns on, there are a couple things that could be happening. Two common problems are a dirty furnace burner or ignitor. Extending and contracting air ducts can also cause loud sounds after the furnace blower comes on. A dirty furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud bang you hear. This could end up being a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which may be very expensive.
The other problem, stretching and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your equipment is making the loud boom and it is produced by your air ducts, it could be a sign of undersized ducts, closed vents, or a clogged air filter. All American Air Service Experts is happy to set up an appointment to diagnose your problem and get your home back in shape for the winter. Ultimately, this will also give you improved comfort as well.
