When your furnace is running like it should, it should give heat without creating too much sound. While it’s common to notice your furnace making noise as it starts up, other sounds are signaling your furnace should get immediate professional help.
Here are some of the most reported 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 Oxford, MS.
1. Furnace Making a Banging Noise
You could have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These range from gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s important to book yearly furnace maintenance with Franklin's Heating & Air Conditioning, Inc. One of the tasks our pros 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 when ignition is delayed. The following gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can emit carbon monoxide, which is normally vented outside. This toxic gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Franklin's Heating & Air Conditioning, Inc urges you to turn it off and contacting us at 662-281-1231. Excessive natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide hot air across your house. If the ductwork wasn’t installed properly or is getting dated, it can make a lot of noise when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Call Franklin's Heating & Air Conditioning, Inc at 662-281-1231 and we’ll figure out 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 usually indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air across your rooms, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like a loose screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating professionals at 662-281-1231 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it could use 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 professionals can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Franklin's Heating & Air Conditioning, Inc can provide support. It’s essential to get loose ductwork repaired quickly, because it can create comfort problems in your residence and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Shut down your furnace off now and contact us at 662-281-1231 for help.
