When your furnace is operating properly, it should provide warmth without making too much disruption. While it’s normal to notice your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional help.
Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Buellton, California.
1. Furnace Making a Banging Noise
You may have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s essential to book routine furnace maintenance with Allstar Heating & Air Conditioning. One of the things our techs do during this service is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can leak carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Allstar Heating & Air Conditioning recommends turning it off and contacting us at 805-242-9638. Too much natural gas in your furnace or a ruptured heat exchanger are critical issues that require immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air across your house. If the ductwork wasn’t designed right or is aging, it can make a lot of noise when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Allstar Heating & Air Conditioning at 805-242-9638 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates an electrical situation, 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 is loose, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air around your rooms, and a capacitor, which starts the motor. If either of these pieces are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something little, like an unsecure screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at 805-242-9638 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, Allstar Heating & Air Conditioning can provide support. It’s critical to get loose ductwork fixed quickly, since it can make comfort issues in your home and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and call us at 805-242-9638 for assistance.
