When your furnace is running like it should, it should give warmth without making too much sound. While it’s common to catch your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional help.
Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Omaha, Nebraska.
1. Furnace Making a Banging Noise
You may have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over time, so that’s why it’s essential to book routine furnace maintenance with Interstate Heating & Air Conditioning. One of the things our technicians complete during this work is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can emit carbon monoxide, which is normally emitted away from your home. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Interstate Heating & Air Conditioning urges you to turn it off and calling us at 402-509-5940. Too much natural gas in your furnace or a cracked heat exchanger are dangerous problems that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air across your home. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Contact Interstate Heating & Air Conditioning at 402-509-5940 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 frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or chilly air throughout your space, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be the result of something small, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 402-509-5940 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing may need to be greased. We are aware that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing sound, Interstate Heating & Air Conditioning can assist you. It’s essential to get loose ductwork fixed without delay, because it can make comfort problems in your residence and inflate your gas expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Turn off your furnace off now and call our professionals at 402-509-5940 for support.
