When your furnace is working correctly, it should provide warm air without making too much noise. While it’s normal to catch your furnace making noise as it turns on, other sounds are signaling your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Tomball, Texas.

1. Furnace Makes Banging or Knocking Sounds

You might have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These involve gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s essential to book yearly furnace maintenance with Premium Air Services LLC. One of the things our professionals perform during this work is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can emit carbon monoxide, which is normally emitted away from your home. This dangerous gas can be deadly 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 calling us at 713-364-9957. Too much natural gas in your furnace or a cracked heat exchanger are critical issues that require prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed right or is aging, it can make a lot of noise when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Contact Premium Air Services LLC at 713-364-9957 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cold air across your home, and a capacitor, which turns on the motor. If either of these parts 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 could be due to something minor, like a loose screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 713-364-9957 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 could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing noise, Premium Air Services LLC can help. It’s essential to get loose ductwork repaired quickly, as it can make comfort problems in your home and inflate your gas bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off right away and reach us at 713-364-9957 for support.
