When your furnace is running correctly, it should deliver warm air without generating too much sound. While it’s common to catch your furnace making noise as it begins running, other sounds are signaling your furnace should get immediate professional assistance.
Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Odessa, Texas.
1. Furnace Making a Banging Noise
You might have a serious issue 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 several problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s important to book seasonal furnace maintenance with Redhawk Heating & Air Conditioning. One of the things our technicians complete during this appointment is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is regularly released outside. This dangerous gas can be lethal 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. Significant natural gas in your furnace or a fractured heat exchanger are serious troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver heated air throughout your home. If the ductwork wasn’t installed right or is aging, it can be loud when your furnace is heating. This can be the case 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 observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air around your house, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be due to something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 432-237-0168 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s running, 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 realize that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still noticing sound, Redhawk Heating & Air Conditioning can help. It’s critical to get loose ductwork fixed quickly, because it can make comfort issues in your house and increase your utility bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and reach us at 432-237-0168 for help.
