When your furnace is running like it should, it should give heat without generating too much disruption. While it’s normal to catch your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional assistance.

Here are some of the most common furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Pacheco, California.

1. Furnace Making a Banging Noise

You could have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These range from gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s critical to schedule routine furnace maintenance with Clean Air HVAC. One of the things our pros do during this work is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can break your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can discharge carbon monoxide, which is normally vented away from your home. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Clean Air HVAC recommends turning it off and calling us at 925-233-6238. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous problems that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air across your residence. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Call Clean Air HVAC at 925-233-6238 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 usually means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cold air across your home, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something small, like an unsecure screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 925-233-6238 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance often slips your mind, but our pros can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Clean Air HVAC can help. It’s essential to get loose ductwork repaired quickly, because it can create comfort problems in your home and increase your energy bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and contact us at 925-233-6238 for support.
