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 may indicate 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 becomes grimy as time passes, so that’s why it’s essential to set routine furnace maintenance with ACS Heating and Air Conditioning. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is normally released away from your home. This dangerous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, ACS Heating and Air Conditioning urges you to turn it off and calling us at 770-450-1539. Excessive natural gas in your furnace or a cracked heat exchanger are critical issues that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air around 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 can be the case if your furnace makes a banging noise when it shuts off. Contact ACS Heating and Air Conditioning at 770-450-1539 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 means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the right voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air throughout your home, and a capacitor, which starts the motor. If either of these pieces are going out, 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 little, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 770-450-1539 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still sensing sound, ACS Heating and Air Conditioning can provide support. It’s essential to get loose ductwork repaired fast, since it can result in comfort troubles in your home and increase your energy costs.
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 noise often means there’s trouble with your furnace’s blower. Turn off your furnace off right away and reach our pros at 770-450-1539 for support.
