When your furnace is working properly, it should provide warmth without generating too much sound. While it’s normal to hear your furnace making noise as it turns on, other disruptions are indicating your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they could 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 Neptune City, NJ.
1. Furnace Making a Banging Noise
You could have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These range from gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over time, so that’s why it’s essential to book annual furnace maintenance with Aggressive Mechanical. One of the things our professionals complete during this appointment is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can emit carbon monoxide, which is regularly emitted outdoors. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Aggressive Mechanical recommends turning it off and calling us at 732-806-5536. Excessive natural gas in your furnace or a broken heat exchanger are critical issues that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air throughout your home. If the ductwork wasn’t put in properly or is getting dated, 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. Get in touch with Aggressive Mechanical at 732-806-5536 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box is loose, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cooled air around your space, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something small, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals at 732-806-5536 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, Aggressive Mechanical can assist you. It’s critical to get loose ductwork taken care of quickly, since it can result in comfort issues in your home and increase your energy bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Shut down your furnace off immediately and reach us at 732-806-5536 for assistance.
