When your furnace is working like it should, it should give warmth without generating too much disruption. While it’s expected to hear your furnace making noise as it turns on, other sounds are indicating your furnace needs immediate professional help.
Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Alice, TX.
1. Furnace Making a Banging Noise
You may have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s important to book routine furnace maintenance with Rescue Heating & Air . One of the jobs our professionals perform during this work 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 following gas buildup can break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can discharge carbon monoxide, which is regularly released away from your home. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Rescue Heating & Air recommends turning it off and contacting us at 361-265-4371. Significant natural gas in your furnace or a fractured heat exchanger are dangerous issues that require fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air throughout your residence. If the ductwork wasn’t designed correctly or is getting dated, it can be loud when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Call Rescue Heating & Air at 361-265-4371 and we’ll figure out 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 often indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air throughout your rooms, and a capacitor, which triggers 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 due to something small, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and calling our heating specialists at 361-265-4371 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our pros can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing sound, Rescue Heating & Air can assist you. It’s critical to get loose ductwork fixed without delay, because it can make comfort issues in your residence and inflate your heating expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and call our pros at 361-265-4371 for assistance.
