When your furnace is running correctly, it should give heat without creating too much noise. While it’s common to catch your furnace making noise as it starts up, other sounds are showing your furnace requires immediate professional assistance.
Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Oxford, Mississippi.
1. Furnace Makes Banging or Knocking Sounds
You may have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s critical to book annual furnace maintenance with Franklin's Heating & Air Conditioning, Inc. One of the tasks our techs complete during this appointment is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can emit carbon monoxide, which is regularly emitted outside. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Franklin's Heating & Air Conditioning, Inc recommends turning it off and reaching us at 662-281-1231. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move heated air across your house. If the ductwork wasn’t put in properly or is getting old, it can be loud when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Franklin's Heating & Air Conditioning, Inc at 662-281-1231 and we’ll pinpoint 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 means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air around your house, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be related to something little, like an unsecure screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros at 662-281-1231 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to alert you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be greased. We realize that maintenance frequently slips your mind, but our pros can get your furnace operating quietly again rapidly.
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 notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Franklin's Heating & Air Conditioning, Inc can assist you. It’s essential to get loose ductwork fixed quickly, as it can create comfort issues in your residence and inflate your energy expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Shut down your furnace off immediately and contact us at 662-281-1231 for assistance.
