Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in East Bernard, Texas.
1. Furnace Makes Banging or Knocking Sounds
You could have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over time, so that’s why it’s essential to set seasonal furnace maintenance with E.B. Air. One of the things our professionals complete during this service is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can leak carbon monoxide, which is regularly vented outside. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, E.B. Air advises turning it off and contacting us at 979-335-4262. Too much natural gas in your furnace or a ruptured heat exchanger are critical problems that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air throughout your home. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Contact 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 frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air across your rooms, and a capacitor, which starts the motor. If either of these parts 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 related to something minor, like an unsecure screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 979-335-4262 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
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 last couple of years, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance often slips your mind, but our pros can get your furnace operating quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, E.B. Air can help. It’s important to get loose ductwork taken care of without delay, since it can create comfort issues in your home and increase your utility bills.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you hear 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 right away and call our professionals at 979-335-4262 for help.
