When your furnace is working correctly, it should deliver warmth without creating too much noise. While it’s common to hear your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional help.
Here are some of the most reported furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating professionals are here to help with the best furnace repair in Troy, OH.
1. Furnace Making a Banging Noise
You could have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s essential to schedule seasonal furnace maintenance with Edington Heating & Cooling Inc. One of the things our professionals complete 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 takes longer than normal. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can emit carbon monoxide, which is normally emitted away from your home. This dangerous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Edington Heating & Cooling Inc advises turning it off and calling us at 937-558-9478. Excessive natural gas in your furnace or a broken heat exchanger are hazardous troubles that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air across your home. If the ductwork wasn’t designed correctly or is aging, it can make a lot of noise when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Call Edington Heating & Cooling Inc at 937-558-9478 and we’ll figure out 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 often indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cold air throughout your rooms, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be the result of something small, like an unsecure screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and calling our heating pros at 937-558-9478 for assistance.
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 could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be dilapidated or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently due to 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 noticing whistling, Edington Heating & Cooling Inc can assist you. It’s important to get loose ductwork repaired without delay, since it can create comfort problems in your house and inflate your energy bills.
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 usually means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and reach us at 937-558-9478 for support.
