Why Your Furnace May Be Making These Noises
It’s that time of year when homeowners start turning on their heating systems to settle in for a frigid winter. Unfortunately, when some heaters start up, especially if it hasn’t received a seasonal heating tune-up, there are some troubles that need to be inspected. A big problem you may encounter is your furnace making weird noises – check out these furnace noises you should never ignore.
If you hear a loud scratching noise that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear something like this, shut off your furnace immediately and call Service Experts Heating, Air Conditioning & Plumbing to inspect the furnace. There are a couple things that could be wrong with the blower wheel. First, it might just be loose and if the component is not too harmed, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount itself broke, causing the whole blower assembly to rattle uncontrollably. One of our service professionals 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 love.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a handful of things that could be going on. Two common things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud booms after the furnace blower turns on. A soiled furnace burner or ignitor could holdup the burners from igniting, forcing gas to build up. When the gas does finally ignite, it will create the loud pop you hear. This could end up being a safety issue, especially if one of these small explosions caused the heat exchanger to break. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very pricey.
The other trouble, stretching and contracting air ducts, is a common noise complaint for people with metal ducts. If your system is making the loud pop and it is produced by your air ducts, it could be a sign of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating, Air Conditioning & Plumbing is happy to set up an appointment to diagnose your issue and get your home back in working order. Additionally, this will also give you improved comfort as well.
If you hear a high-pitched sound, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. An annual system tune-up will help discover these issues before they become major problems so make sure you call us at 866-397-3787 and we’ll make sure your heating system is ready to keep you safe and warm all winter long.
