When your furnace is operating like it should, it should deliver warm air without creating too much disruption. While it’s normal to hear your furnace making noise as it starts up, other noises are signaling your furnace needs immediate professional help.
Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating pros are here to help with the best furnace repair in Buellton, California.
1. Furnace Making a Banging Noise
You might have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s essential to book seasonal furnace maintenance with Allstar Heating & Air Conditioning. One of the tasks our pros complete during this work is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Allstar Heating & Air Conditioning urges you to turn it off and calling us at 805-242-9638. Excessive natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air around your home. If the ductwork wasn’t designed properly or is getting dated, it can be loud when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Allstar Heating & Air Conditioning at 805-242-9638 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or chilly air throughout your home, and a capacitor, which starts the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be the result of something minor, like a loose screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at 805-242-9638 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We know that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, Allstar Heating & Air Conditioning can help. It’s critical to get loose ductwork taken care of quickly, since it can create comfort problems in your residence and inflate your heating expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s an issue with your furnace’s blower. Turn off your furnace off now and call our pros at 805-242-9638 for help.
