When your furnace is working properly, it should provide heat without creating too much disruption. While it’s common to catch your furnace making noise as it begins running, other noises are signaling your furnace needs immediate professional assistance.
Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Kearney, Nebraska.
1. Furnace Making a Banging Noise
You may have a serious situation 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 several problems. These range from gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with Thurston Heating & Air Conditioning. One of the jobs our professionals perform during this service is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can leak carbon monoxide, which is ordinarily released outside. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Thurston Heating & Air Conditioning advises turning it off and calling us at 308-624-3485. Excessive natural gas in your furnace or a ruptured heat exchanger are dangerous problems that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide hot air throughout your home. If the ductwork wasn’t put in right or is getting old, it can be noisy when your furnace is on. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with Thurston Heating & Air Conditioning at 308-624-3485 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cold air around your home, and a capacitor, which starts the motor. If either of these parts are going out, 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 due to something small, like an unsecure screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists 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 on, it’s making an effort to tell you it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We are aware that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Thurston Heating & Air Conditioning can provide support. It’s important to get loose ductwork repaired without delay, since it can create comfort troubles in your home and increase your heating expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound typically means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and reach our professionals at 308-624-3485 for assistance.
