When your furnace is operating like it should, it should give warm air without creating too much sound. While it’s common to catch your furnace making noise as it turns on, other noises are indicating your furnace needs immediate professional support.
Here are some of the most frequent furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Toledo, Ohio.
1. Furnace Makes a Banging Sound
You might have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These involve gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over time, so that’s why it’s important to schedule seasonal furnace maintenance with Northwest Services. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can emit carbon monoxide, which is normally released away from your home. This toxic gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Northwest Services recommends turning it off and calling us at 419-548-5017. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous troubles that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air throughout your house. If the ductwork wasn’t put in properly or is getting old, it can make a lot of noise when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Contact Northwest Services at 419-548-5017 and we’ll pinpoint the problem.
2. Furnace Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the right voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cooled air across your rooms, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be related to something little, like a loose screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 419-548-5017 for assistance.
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 could use some TLC. If you’ve skipped 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 professionals can get your furnace heating quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still hearing whistling, Northwest Services can help. It’s essential to get loose ductwork taken care of quickly, as it can make comfort issues in your house and increase your energy expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 419-548-5017 for help.
