It’s that time of year when people start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heating systems start up, especially if it hasn’t undergone a fall heating tune-up, there are some troubles that need to be examined. A major problem you may discover is your furnace making funny noises – take a look at these furnace noises you should never ignore.
Scraping Sound
If you hear a loud scratching racket that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear something like this, shut off your furnace ASAP and call Orangutan Home Services to inspect the equipment. 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 damaged, 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 vibrate uncontrollably. One of our service technicians would be happy to come over and take a look, and get you back to the silent and comfortable home you have come to love.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace turns on, there are a few things that could be happening. Two common issues are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud noises after the heating system blower starts up. A soiled furnace burner or ignitor could holdup 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 cause a safety issue, especially if one of these small explosions caused the heat exchanger to crack. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very expensive.
The other issue, expanding and contracting air ducts, is a common noise complaint for homes with metal ducts. If your system is making the loud bang and it is produced by your air ducts, it could be a symptom of undersized ducts, obstructed vents, or a clogged air filter. Orangutan Home Services is happy to set up an appointment to diagnose your issue and get your home back in working order. Also, this will also result in improved comfort as well.
Whining Noise
If you hear a squealing 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 seasonal furnace tune-up will help discover these issues before they become major problems so make sure you give us a call at 602-906-0111 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
