When your furnace is working correctly, it should provide warmth without making too much noise. While it’s common to catch your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional help.
Here are some of the most frequent furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Northridge, California.
1. Furnace Makes Banging or Knocking Sounds
You might have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over the years, so that’s why it’s essential to book seasonal furnace maintenance with Enertek Air Conditioning & Heating. One of the jobs our pros perform during this appointment is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can leak carbon monoxide, which is regularly released outdoors. This toxic gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Enertek Air Conditioning & Heating advises turning it off and calling us at (818) 727-9993. Excessive natural gas in your furnace or a ruptured heat exchanger are serious problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move hot air across your house. If the ductwork wasn’t put in right or is getting dated, it can make a lot of noise when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Enertek Air Conditioning & Heating at (818) 727-9993 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air around your residence, and a capacitor, which starts the motor. If either of these components are failing, 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 an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at (818) 727-9993 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Whistles
When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still noticing noise, Enertek Air Conditioning & Heating can assist you. It’s important to get loose ductwork taken care of quickly, as it can make comfort troubles in your house and increase your energy expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Switch off your furnace off now and call us at (818) 727-9993 for assistance.
