When your furnace is operating like it should, it should deliver warm air without creating too much noise. While it’s normal to hear your furnace making noise as it begins running, other sounds are indicating your furnace needs immediate professional support.
Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Tomball, TX.
1. Furnace Making a Banging Noise
You might have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s essential to schedule routine furnace maintenance with Premium Air Services LLC. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is regularly vented outside. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Premium Air Services LLC advises turning it off and calling us at 713-364-9957. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous issues that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver hot air throughout your home. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Premium Air Services LLC at 713-364-9957 and we’ll pinpoint 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 typically is telling you there’s an electrical situation, 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 needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air throughout your home, and a capacitor, which starts the motor. If either of these components 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 the result of something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating professionals at 713-364-9957 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be dilapidated or a bearing may need to be lubed. We know that maintenance frequently slips your mind, but our technicians 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 because of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing whistling, Premium Air Services LLC can assist you. It’s important to get loose ductwork taken care of without delay, because it can create comfort issues in your residence and drive up your heating bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Shut down your furnace off right away and reach our professionals at 713-364-9957 for help.
