1. Furnace Making a Banging Noise
You may have a serious 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 few problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over time, so that’s why it’s essential to schedule yearly furnace maintenance with ACS Heating and Air Conditioning. One of the things our techs complete during this service is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can emit carbon monoxide, which is regularly vented outside. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, ACS Heating and Air Conditioning advises turning it off and reaching us at 770-450-1539. Excessive natural gas in your furnace or a fractured heat exchanger are critical problems that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air throughout your house. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Contact ACS Heating and Air Conditioning at 770-450-1539 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cold air throughout your space, and a capacitor, which turns on the motor. If either of these pieces 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 may be the result of something little, like an unsecure screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 770-450-1539 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. We know that maintenance often slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, ACS Heating and Air Conditioning can provide support. It’s important to get loose ductwork taken care of quickly, because it can make comfort issues in your residence and inflate your energy costs.
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 noise frequently means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and reach us at 770-450-1539 for assistance.
