Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Kingsville, TX.
1. Furnace Making a Banging Noise
You may have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty as time passes, so that’s why it’s essential to book yearly furnace maintenance with Four Seasons Air Conditioning and Heating LLC. One of the things our pros complete during this work is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This toxic gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Four Seasons Air Conditioning and Heating LLC advises turning it off and calling us at 361-214-1203. Too much natural gas in your furnace or a fractured heat exchanger are serious problems that require immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air around your home. If the ductwork wasn’t put in properly or is getting old, it can be loud when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Call Four Seasons Air Conditioning and Heating LLC at 361-214-1203 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air across your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something minor, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 361-214-1203 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We realize that maintenance sometimes slips your mind, but our techs can get your furnace heating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still sensing whistling, Four Seasons Air Conditioning and Heating LLC can provide support. It’s essential to get loose ductwork taken care of quickly, since it can make comfort issues in your home and increase your heating costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Shut down your furnace off right away and contact our pros at 361-214-1203 for help.
