When your furnace is working correctly, it should provide warm air without creating too much disruption. While it’s expected to hear your furnace making noise as it begins running, other sounds are indicating your furnace requires immediate professional support.
Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Northridge, California.
1. Furnace Making a Banging Noise
You might have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These range from gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy as time passes, so that’s why it’s important to book seasonal furnace maintenance with Enertek Air Conditioning & Heating. One of the things our techs do during this work is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can emit carbon monoxide, which is normally emitted away from your home. This hazardous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Enertek Air Conditioning & Heating advises turning it off and calling us at (818) 727-9993. Too much natural gas in your furnace or a fractured heat exchanger are dangerous troubles that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air across your residence. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Contact Enertek Air Conditioning & Heating at (818) 727-9993 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or cold air throughout your space, and a capacitor, which starts the motor. If either of these components are failing, 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 due to something minor, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at (818) 727-9993 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to get your attention it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance often slips your mind, but our techs can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still noticing noise, Enertek Air Conditioning & Heating can help. It’s critical to get loose ductwork fixed quickly, because it can create comfort troubles in your residence and inflate your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise usually means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at (818) 727-9993 for support.
