When your furnace is operating correctly, it should provide heat without creating too much sound. While it’s common to catch your furnace making noise as it begins running, other noises are showing your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making a weird 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 may have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s critical to schedule annual furnace maintenance with Van Haaften Plumbing & Heating. One of the jobs our professionals complete during this service is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can leak carbon monoxide, which is regularly emitted away from your home. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Van Haaften Plumbing & Heating recommends turning it off and calling us at 641-628-3621. Too much natural gas in your furnace or a broken heat exchanger are critical problems that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air around your house. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace is on. This can be the case 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 pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or chilly air around your rooms, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something minor, like an unfastened screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating specialists at 641-628-3621 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We realize that maintenance sometimes slips your mind, but our techs 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 the result of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Van Haaften Plumbing & Heating can assist you. It’s critical to get loose ductwork fixed quickly, as it can make comfort problems in your home and inflate your energy costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and contact our professionals at 641-628-3621 for help.
