When your furnace is working correctly, it should provide warm air without generating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional support.
Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Odessa, Texas.
1. Furnace Making a Banging Noise
You might have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be several problems. These include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over the years, so that’s why it’s critical to set yearly furnace maintenance with Redhawk Heating & Air Conditioning. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can leak 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, Redhawk Heating & Air Conditioning recommends turning it off and reaching us at 432-237-0168. Significant natural gas in your furnace or a broken heat exchanger are hazardous troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide warm air throughout your home. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Redhawk Heating & Air Conditioning at 432-237-0168 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 typically indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air throughout your rooms, and a capacitor, which starts the motor. If either of these parts 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 small, like an unsecure screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating specialists at 432-237-0168 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still noticing whistling, Redhawk Heating & Air Conditioning can provide support. It’s critical to get loose ductwork repaired without delay, because it can create comfort troubles in your home and increase your energy costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Shut down your furnace off immediately and call us at 432-237-0168 for assistance.
