It's that time of year when聽people聽start turning on their聽heaters聽to settle in for a聽frigid聽winter. Unfortunately, when some聽heating systems聽start up, especially if it hasn’t聽undergone聽a聽yearly聽heating tune-up, there are some聽issues聽that need to be聽examined. A聽big聽problem you may聽run into聽is your furnace making聽weird聽noises -聽take a look at聽these furnace noises you should never聽ignore.
Scraping Sound
If you hear a loud聽scraping聽racket聽that sounds like metal on metal, there is聽probably聽something聽faulty聽with the blower wheel. If you hear聽a sound聽like this,聽turn off聽your furnace聽immediately聽and call聽天美传媒聽to inspect the聽system. There are聽multiple聽things that could be聽wrong聽with the blower wheel. First, it聽may聽just be loose and if the聽part聽is not too聽damaged, can be tightened. Second, it聽may聽be that the blower wheel is broken and聽in need of replacement. Or third, it聽may聽be that the motor mount聽actually聽broke, causing the聽complete聽blower assembly to聽vibrate聽uncontrollably. One of our service聽technicians聽would be happy to come聽to your home聽and take a look, and get you back to the聽quiet聽and聽cozy聽home you have come to聽expect.
Loud Bang When Furnace Starts
If there is a loud聽bang聽when your furnace聽turns聽on, there are a聽handful of聽things that could be聽occurring. Two聽general聽things聽are a dirty furnace burner or ignitor.聽Stretching聽and contracting air ducts can also聽produce聽loud聽sounds聽after the聽heating聽blower聽comes on. A聽filthy聽furnace burner or ignitor could聽delay聽the burners from igniting,聽causing聽gas to build up. When the gas聽finally does ignite, it will create the loud聽boom聽you hear. This could聽end up being聽a safety issue, especially if one of聽these聽small explosions caused the heat exchanger to聽crack. Not only could that聽cause聽a carbon monoxide leak, but聽you'd end up having聽to replace the heat exchanger, which聽can聽be very聽pricey.
The other聽issue,聽expanding聽and contracting air ducts, is a聽typical聽noise complaint for聽people聽with metal ducts. If your聽system聽is making the loud聽bang聽and it is聽caused by聽your air ducts, it could be聽a sign聽of undersized ducts,聽closed聽vents, or a clogged air filter.聽天美传媒聽is happy to聽visit your home聽to diagnose your聽issue聽and get your home back聽in shape for the winter.聽Additionally, this will also聽give you聽improved comfort as well.
Whining Noise
