When your furnace is operating correctly, it should give heat without generating too much sound. While it’s expected to catch your furnace making noise as it starts up, other noises are signaling your furnace requires immediate professional help.
Here are some of the most common furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in East Bernard, TX.
1. Furnace Making a Banging Noise
You may have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal 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 becomes grimy over the years, so that’s why it’s critical to set seasonal furnace maintenance with E.B. Air, LLC. One of the jobs our techs do during this work is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, E.B. Air, LLC recommends turning it off and calling us at 979-335-4262. Too much natural gas in your furnace or a broken heat exchanger are critical problems that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide heated air around your home. If the ductwork wasn’t installed right or is aging, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with E.B. Air, LLC at 979-335-4262 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually 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 correct voltage. If wires or the box is loose, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or chilly air across your space, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating specialists at 979-335-4262 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, E.B. Air, LLC can help. It’s important to get loose ductwork taken care of without delay, as it can make comfort troubles in your house and increase your energy bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and contact our professionals at 979-335-4262 for assistance.
