When your furnace is operating properly, it should deliver warm air without creating too much disruption. While it’s common to notice your furnace making noise as it begins running, other sounds are showing your furnace requires immediate professional support.
Here are some of the most common furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Hattiesburg, MS.
1. Furnace Making a Banging Noise
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 mean there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over time, so that’s why it’s essential to set annual furnace maintenance with Oak Grove Heating & Air Conditioning. One of the tasks our pros complete during this work is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is normally vented away from your home. This toxic gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Oak Grove Heating & Air Conditioning urges you to turn it off and reaching us at 601-292-9763. Significant natural gas in your furnace or a ruptured heat exchanger are serious troubles that necessitate immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air around your home. If the ductwork wasn’t designed right or is aging, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Oak Grove Heating & Air Conditioning at 601-292-9763 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or chilly air around your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something little, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 601-292-9763 for help.
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 needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, Oak Grove Heating & Air Conditioning can help. It’s critical to get loose ductwork taken care of without delay, as it can make comfort issues in your residence and drive up your utility expenses.
6. Furnace Making a 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 a problem with your furnace’s blower. Switch off your furnace off instantly and call us at 601-292-9763 for assistance.
