Now is when people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t had a fall heating tune-up, there are some issues that need to be examined. A big problem you may discover is your furnace making weird noises – check out these furnace noises you should never disregard.
If you hear a loud raking racket that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear a sound like this, turn off your furnace immediately and call Freschi Service Experts to inspect the system. There are a few things that could be wrong with the blower wheel. First, it might just be loose and if the part is not too harmed, can be tightened. Second, it could be that the blower wheel is broken and in need of replacement. Or third, it could be that the motor mount actually broke, causing the complete blower assembly to rattle uncontrollably. One of our service technicians would be happy to come to your home and take a look, and get you back to the silent and warm home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a couple things that could be going on. Two common issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud booms after the heating system blower starts up. A soiled furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas finally ignites, 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 break. Not only could that produce a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which may be very pricey.
The other problem, expanding and contracting air ducts, is a typical 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, obstructed vents, or a clogged air filter. Freschi Service Experts is happy to visit your home to diagnose your trouble and get your home back in working order. Additionally, this will also result in improved comfort as well.
If you hear a squealing 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. A seasonal furnace tune-up will help find these issues before they become major problems so make sure you give us a call at 925-384-1303 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
