This is the time of year homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heaters start up, especially if it hasn’t had a yearly heating tune-up, there are some troubles that need to be assessed. A serious problem you may encounter is your furnace making funny noises – read about these furnace noises you should never neglect.
If you hear a loud raking noise that sounds like metal on metal, there is possibly something defective with the blower wheel. If you hear a noise like this, power off your furnace right away and call Service Experts Commercial HVAC to inspect the equipment. There are a couple things that could be amiss with the blower wheel. First, it might just be loose and if the part is not too damaged, can be tightened. Second, it may 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 complete blower assembly to shake uncontrollably. One of our service experts would be happy to come to your home and take a look, and get you back to the noiseless and warm home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a handful of things that could be happening. Two common issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud booms after the heating blower turns on. A dirty furnace burner or ignitor could prevent the burners from igniting, resulting in gas to build up. When the gas finally does ignite, it will create the loud boom 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 cause a carbon monoxide leak, but you will have to replace the heat exchanger, which can be very expensive.
The other problem, extending and contracting air ducts, is a typical noise complaint for homeowners with metal ducts. If your equipment is making the loud pop and it is a result of your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Service Experts Commercial HVAC is happy to set up an appointment to diagnose your trouble and get your home back to order. Ultimately, this will also provide improved comfort as well.
If you hear a whining noise, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. An annual system tune-up will help discover these issues before they become serious problems so make sure you contact us at 289-201-2346 and we’ll make sure your heating system is ready to keep you safe and warm all winter long.
