When your furnace is running correctly, it should provide warmth without generating too much disruption. While it’s expected to notice your furnace making noise as it turns on, other disruptions are indicating your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Pella, Iowa.

1. Furnace Makes Banging or Knocking Sounds

You might have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These include gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s critical to schedule routine furnace maintenance with Van Haaften Plumbing & Heating. One of the jobs our professionals complete during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can leak carbon monoxide, which is normally vented outdoors. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Van Haaften Plumbing & Heating urges you to turn it off and contacting us at 641-628-3621. Excessive natural gas in your furnace or a broken heat exchanger are critical issues that require prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air around your home. If the ductwork wasn’t designed properly or is aging, it can be loud when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Van Haaften Plumbing & Heating at 641-628-3621 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cooled air across your residence, and a capacitor, which triggers 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 can be due to something small, like an unfastened screw, or something major, like a broken part. In either case, we advise shutting your furnace off and calling our heating pros at 641-628-3621 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing sound, Van Haaften Plumbing & Heating can assist you. It’s important to get loose ductwork taken care of fast, because it can create comfort problems in your residence and inflate your utility costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off right away and call us at 641-628-3621 for help.
