When your furnace is running properly, it should provide warm air without making too much noise. While it’s common to catch your furnace making noise as it begins running, other sounds are indicating your furnace requires immediate professional assistance.

Here are some of the most common furnace noises and what they can 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 Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over time, so that’s why it’s important to schedule routine furnace maintenance with Van Haaften Plumbing & Heating. One of the jobs our professionals perform during this service is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup might crack your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is normally emitted outside. This toxic gas can be deadly 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 calling us at 641-628-3621. Too much natural gas in your furnace or a ruptured heat exchanger are serious issues that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air throughout your residence. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Call Van Haaften Plumbing & Heating at 641-628-3621 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical situation, 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 detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air throughout your home, and a capacitor, which starts the motor. If either of these pieces 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 related to something minor, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 641-628-3621 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We know that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing sound, Van Haaften Plumbing & Heating can help. It’s important to get loose ductwork repaired without delay, since it can make comfort issues in your home 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 racket often means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and call our pros at 641-628-3621 for assistance.
