When your furnace is operating like it should, it should deliver warm air without generating too much sound. While it’s common to notice your furnace making noise as it starts up, other sounds are signaling your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to help with the best furnace repair in East Bernard, Texas.
1. Furnace Makes a Banging Sound
You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These range from gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s critical to set routine furnace maintenance with E.B. Air. One of the things our pros complete during this appointment is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can emit carbon monoxide, which is normally emitted outside. This hazardous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, E.B. Air urges you to turn it off and contacting us at 979-335-4262. Too much natural gas in your furnace or a fractured heat exchanger are critical problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air across your home. If the ductwork wasn’t designed right or is getting old, it can be loud when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with E.B. Air at 979-335-4262 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical situation, 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 is loose, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cold air throughout your home, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be due to something minor, like a loose screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and contacting our heating pros at 979-335-4262 for assistance.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be greased. We realize that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, E.B. Air can help. It’s essential to get loose ductwork taken care of fast, as it can result in comfort problems in your home and inflate your energy costs.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off now and contact our pros at 979-335-4262 for support.
