When your furnace is operating correctly, it should give heat without generating too much disruption. While it’s normal to notice your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating specialists are here to help with the best furnace repair in Lodi, California.
1. Furnace Making a Banging Noise
You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s essential to book routine furnace maintenance with Tokay. One of the jobs our techs complete during this appointment is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can leak carbon monoxide, which is ordinarily vented away from your home. This toxic gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Tokay recommends turning it off and calling us at 209-257-3156. 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 move warm air throughout your residence. If the ductwork wasn’t designed properly or is getting dated, it can make a lot of noise when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Call Tokay at 209-257-3156 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait 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 proper voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or cooled air around your space, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something little, like an unsecure screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals at 209-257-3156 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting 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 may need to be lubed. We realize that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Tokay can provide support. It’s important to get loose ductwork fixed without delay, as it can result in comfort troubles in your residence and increase your utility costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact our pros at 209-257-3156 for support.
