When your furnace is operating properly, it should provide warmth without generating too much disruption. While it’s normal to notice your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Newton, 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 include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy as time passes, so that’s why it’s essential to book yearly furnace maintenance with Brookwood Inc. One of the things our pros perform during this appointment is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is regularly emitted away from your home. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Brookwood Inc recommends turning it off and contacting us at 641-316-9803. Excessive natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air around your residence. If the ductwork wasn’t designed properly or is getting old, it can be noisy when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call Brookwood Inc at 641-316-9803 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 typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cold air throughout your space, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace turns on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be related to something small, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating pros at 641-316-9803 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We know that maintenance often slips your mind, but our techs can get your furnace operating quietly again rapidly.
5. Furnace Whistles
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing noise, Brookwood Inc can provide support. It’s critical to get loose ductwork repaired fast, as it can make comfort problems in your residence and drive up your utility bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 641-316-9803 for support.
