When your furnace is running correctly, it should provide heat without making too much disruption. While it’s common to catch your furnace making noise as it turns on, other sounds are signaling your furnace should get immediate professional support.
Here are some of the most frequent furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Omaha, Nebraska.
1. Furnace Making a Banging Noise
You might have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over the years, so that’s why it’s critical to schedule annual furnace maintenance with Interstate Heating & Air Conditioning. One of the tasks our techs do during this service 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 subsequent gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily released outside. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Interstate Heating & Air Conditioning advises turning it off and contacting us at 402-509-5940. Excessive natural gas in your furnace or a broken heat exchanger are hazardous troubles that should get immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air across your home. If the ductwork wasn’t installed correctly or is getting dated, it can be noisy when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Interstate Heating & Air Conditioning at 402-509-5940 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 often indicates an electrical situation, 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 needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air throughout your rooms, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be the result of something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 402-509-5940 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We are aware that maintenance often slips your mind, but our technicians can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still noticing noise, Interstate Heating & Air Conditioning can assist you. It’s critical to get loose ductwork repaired quickly, as it can result in comfort troubles in your house and inflate your utility 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 usually means there’s trouble with your furnace’s blower. Switch off your furnace off now and contact our pros at 402-509-5940 for help.
