When your furnace is operating like it should, it should give heat without generating too much sound. While it’s normal to notice your furnace making noise as it starts up, other sounds are signaling your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Buellton, California.

1. Furnace Making a Banging Noise

You might have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These range from gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over the years, so that’s why it’s critical to book annual furnace maintenance with Allstar Heating & Air Conditioning. One of the things our pros perform during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can discharge carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Allstar Heating & Air Conditioning urges you to turn it off and calling us at 805-242-9638. Too much natural gas in your furnace or a fractured heat exchanger are dangerous troubles that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air throughout your house. If the ductwork wasn’t designed right or is getting dated, it can be noisy when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Call Allstar Heating & Air Conditioning at 805-242-9638 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or chilly air throughout your residence, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 805-242-9638 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to tell you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance often slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still hearing noise, Allstar Heating & Air Conditioning can provide support. It’s critical to get loose ductwork taken care of without delay, because it can create comfort issues in your house and increase your heating costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Shut down your furnace off immediately and contact us at 805-242-9638 for help.
