When your furnace is running like it should, it should give warm air without making too much disruption. While it’s common to hear your furnace making noise as it begins running, other sounds are showing your furnace requires immediate professional support.

Here are some of the most reported furnace noises and what they can 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 Auburn, California.

1. Furnace Makes Banging or Knocking Sounds

You may have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over time, so that’s why it’s critical to book seasonal furnace maintenance with Forster Heating. One of the things our professionals do during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may crack your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can emit carbon monoxide, which is normally released 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, Forster Heating recommends turning it off and calling us at 530-885-8081. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide heated air across your house. If the ductwork wasn’t installed properly or is aging, it can make a lot of noise when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Contact Forster Heating at 530-885-8081 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you could detect 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 components are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be the result of something minor, like a loose screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating professionals at 530-885-8081 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Forster Heating can assist you. It’s essential to get loose ductwork fixed quickly, because it can make comfort problems in your house 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 usually means there’s an issue with your furnace’s blower. Turn off your furnace off right away and contact our professionals at 530-885-8081 for assistance.
