1. Furnace Making a Banging Noise
You might have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These range from gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s essential to schedule seasonal furnace maintenance with Service Max Heating & Air Conditioning. One of the tasks our techs do during this appointment is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can emit carbon monoxide, which is ordinarily released outdoors. This hazardous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Service Max Heating & Air Conditioning advises turning it off and reaching us at 360-255-5857. Significant natural gas in your furnace or a broken heat exchanger are serious troubles that should get prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air throughout your house. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Service Max Heating & Air Conditioning at 360-255-5857 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air throughout your space, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be related to something little, like an unsecure screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 360-255-5857 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be greased. We realize that maintenance often slips your mind, but our techs can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Service Max Heating & Air Conditioning can help. It’s essential to get loose ductwork taken care of quickly, because it can result in comfort issues in your residence and inflate your gas costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Shut down your furnace off now and call us at 360-255-5857 for assistance.
