When your furnace is operating properly, it should deliver warm air without generating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional assistance.
Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making a weird noise, our friendly heating professionals are here to assist with the best furnace repair in Magnolia, Texas.
1. Furnace Makes a Banging Sound
You might have a critical problem 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 involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s important to schedule routine furnace maintenance with JTech Mechanical. One of the tasks our technicians perform during this appointment is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can emit carbon monoxide, which is normally emitted outdoors. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, JTech Mechanical recommends turning it off and reaching us at 281-231-8768. Excessive natural gas in your furnace or a fractured heat exchanger are serious problems that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air around your house. If the ductwork wasn’t installed right or is aging, it can be loud when your furnace is on. This could be the problem if your furnace makes a banging noise when it shuts off. Contact JTech Mechanical at 281-231-8768 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently is telling you there’s 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 isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air around your rooms, and a capacitor, which triggers the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be the result of something small, like a loose screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 281-231-8768 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort 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 may need to be lubed. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again quickly.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, JTech Mechanical can help. It’s critical to get loose ductwork taken care of fast, since it can result in comfort troubles in your residence and drive up your utility bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and contact our professionals at 281-231-8768 for assistance.
