When your furnace is running correctly, it should provide heat without generating too much noise. While it’s expected to hear your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Odessa, Texas.
1. Furnace Makes a Banging Sound
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 couple of problems. These include gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty as time passes, so that’s why it’s critical to set seasonal furnace maintenance with Redhawk Heating & Air Conditioning. One of the tasks our technicians complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can emit carbon monoxide, which is regularly emitted outdoors. This dangerous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Redhawk Heating & Air Conditioning recommends turning it off and reaching us at 432-237-0168. Too much natural gas in your furnace or a broken heat exchanger are hazardous issues that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air around your home. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Redhawk Heating & Air Conditioning at 432-237-0168 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often 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 correct voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air throughout your space, and a capacitor, which starts the motor. If either of these parts 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 the result of something small, like a loose screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating pros at 432-237-0168 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to alert you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We know that maintenance often slips your mind, but our professionals can get your furnace operating quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still sensing noise, Redhawk Heating & Air Conditioning can assist you. It’s critical to get loose ductwork taken care of quickly, because it can create comfort troubles in your house and inflate your energy bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact us at 432-237-0168 for assistance.
