Banging, Screeching and Rattling: What 6 Ordinary Furnace Noises Indicate

When your furnace is operating properly, it should give heat without generating too much disruption. While it’s normal to notice your furnace making noise as it turns on, other disruptions are showing your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they could be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Tomball.

1. Furnace Making a Banging Noise

You might have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s essential to book routine furnace maintenance with Premium Air Services LLC. One of the things our pros perform during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily vented outdoors. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Premium Air Services LLC urges you to turn it off and contacting us at 713-364-9957. Significant natural gas in your furnace or a broken heat exchanger are serious issues that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air throughout your residence. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is on. This might be the issue 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 wait 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 depends on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cold air across your residence, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it might be due to something little, like a loose screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros 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 running, it’s making an effort to tell you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance frequently slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing whistling, Premium Air Services LLC can help. It’s important to get loose ductwork fixed without delay, because it can create comfort issues in your home and increase your energy expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice 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 immediately and contact our professionals at 713-364-9957 for support.
