When your furnace is running properly, it should give heat without making too much disruption. While it’s common to notice your furnace making noise as it begins running, other disruptions are signaling your furnace requires immediate professional help.
Here are some of the most reported furnace noises and what they might 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 Kearney, Nebraska.
1. Furnace Making a Banging Noise
You could have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over time, so that’s why it’s essential to book yearly furnace maintenance with Thurston Heating & Air Conditioning. One of the things our techs complete during this appointment is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is normally vented outdoors. This dangerous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Thurston Heating & Air Conditioning recommends turning it off and contacting us at 308-624-3485. Significant natural gas in your furnace or a cracked heat exchanger are hazardous problems that require fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air throughout your home. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Call Thurston Heating & Air Conditioning at 308-624-3485 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or chilly air across your house, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something small, like a loose screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 308-624-3485 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. 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 the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Thurston Heating & Air Conditioning can help. It’s important to get loose ductwork taken care of without delay, as it can make comfort problems in your home and increase your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s an issue with your furnace’s blower. Switch off your furnace off immediately and reach our pros at 308-624-3485 for support.
