When your furnace is operating like it should, it should deliver heat without making too much disruption. While it’s normal to hear your furnace making noise as it begins running, other sounds are indicating your furnace should get immediate professional support.
Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Mobile, Alabama.
1. Furnace Making a Banging Noise
You may have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over time, so that’s why it’s critical to book seasonal furnace maintenance with Farnell Heating & Air Conditioning Inc. One of the things our professionals complete during this appointment is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise if ignition is delayed. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can leak carbon monoxide, which is normally emitted outside. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Farnell Heating & Air Conditioning Inc recommends turning it off and calling us at 251-471-2674. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that should get immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air across your residence. If the ductwork wasn’t put in right or is aging, it can be loud when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Farnell Heating & Air Conditioning Inc at 251-471-2674 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical issue, 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 needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air across your rooms, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 251-471-2674 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be greased. We realize that maintenance often slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still hearing whistling, Farnell Heating & Air Conditioning Inc can help. It’s important to get loose ductwork repaired without delay, since it can create comfort problems in your residence and inflate your heating bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Switch off your furnace off right away and call our professionals at 251-471-2674 for help.
