When your furnace is running properly, it should deliver heat without creating too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are indicating your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Auburn, California.

1. Furnace Makes a Banging Sound

You could have an urgent 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 involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s important to schedule routine furnace maintenance with Forster Heating. One of the tasks our techs complete during this service is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Forster Heating urges you to turn it off and reaching us at 530-885-8081. Excessive natural gas in your furnace or a broken heat exchanger are hazardous issues that should get 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 installed correctly or is getting dated, it can be noisy when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Contact Forster Heating at 530-885-8081 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or cold air across your home, and a capacitor, which triggers the motor. If either of these parts are fading, 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 the result of something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 530-885-8081 for support.

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 making an effort to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance often slips your mind, but our techs can get your furnace heating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Forster Heating can help. It’s important to get loose ductwork fixed fast, since it can make comfort troubles in your home and increase your utility expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off immediately and call our professionals at 530-885-8081 for help.

When you’re getting an atypical noise from your furnace, Forster Heating is ready to provide assistance. Contact us at 530-885-8081 to request your furnace repair appointment right away.
