When your furnace is operating like it should, it should give heat without generating too much sound. While it’s normal to catch your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional support.
Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Rockford, Illinois.
1. Furnace Makes Banging or Knocking Sounds
You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These include gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over time, so that’s why it’s critical to set seasonal furnace maintenance with Temperature Doctors Heating & Cooling. One of the jobs our pros 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 if ignition is delayed. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can discharge carbon monoxide, which is normally vented outside. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Temperature Doctors Heating & Cooling urges you to turn it off and contacting us at (815) 914-6197. Significant natural gas in your furnace or a ruptured heat exchanger are serious troubles that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air across your house. If the ductwork wasn’t put in properly or is aging, it can be loud when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Temperature Doctors Heating & Cooling at (815) 914-6197 and we’ll pinpoint the problem.
2. Furnace Buzzes Constantly
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 uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cold air around your rooms, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something small, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at (815) 914-6197 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it requires some TLC. If you’ve forgotten 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 techs can get your furnace heating quietly again quickly.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing noise, Temperature Doctors Heating & Cooling can help. It’s important to get loose ductwork repaired without delay, because it can make comfort problems in your house and inflate your gas bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and contact our pros at (815) 914-6197 for assistance.
