When your furnace is operating correctly, it should deliver heat without generating too much disruption. While it’s expected to catch your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional support.
Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Georgetown, TX.
1. Furnace Making a Banging Noise
You might have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These range from gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s essential to set seasonal furnace maintenance with Miller Climate Control LLC. One of the things our pros complete during this work is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may break your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily vented outdoors. This hazardous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Miller Climate Control LLC recommends turning it off and reaching us at 512-937-2001. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air throughout your residence. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Call Miller Climate Control LLC at 512-937-2001 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 often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or chilly air throughout your home, 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 could be due to something minor, like an unsecure screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 512-937-2001 for assistance.
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 neglected furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We realize that maintenance often slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still hearing noise, Miller Climate Control LLC can provide support. It’s critical to get loose ductwork fixed fast, because it can make comfort issues in your home and increase your gas bills.
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 sound typically means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and reach us at 512-937-2001 for help.
