Strange noises could be warning signs that something is wrong, and you’ll want to address the issue right away.

Higher bills could indicate that you have a gas line leak.
A whistling sound coming from your gas lines or gas appliances is one of the most common signs of a leak, especially if you also smell sulfur or rotten eggs. Other common signs of a gas leak include:
Typically, worn-out gas lines or connectors (which connect gas appliances to supply pipes) cause gas line leaks. However, improper appliance or gas line installation, weather corrosion, and broken pipes can also cause leaks.
Solution: If you suspect you have a gas leak, you may be in danger. Leave your home immediately, and call 911 and your gas company right away. After dealing with emergency leaks, you can hire a professional plumber to install new gas lines or repair your existing ones to ensure they operate efficiently and safely.
Is the whistling sound mostly coming from your gas fireplace?
If you hear the whistling sound near a gas appliance such as a fireplace, an obstruction in the gas supply might be the cause.
Even tiny dirt or dust particles can disrupt gas flow through the line. When this happens, the pressure of the gas moving against the object obstructing the line produces an audible whistling noise.
Solution: Have a licensed professional come to your home to inspect your gas lines. To prevent future issues, try to keep your gas appliances and their attachments as clean as possible. Hiring a contractor for regular maintenance can help with this.
It can be normal to hear slight whistling noises coming from your gas meter. But, if it’s constant, there’s still the chance that it could be a problem. We’ll explain how a gas meter can cause a whistling noise:
To measure the amount of natural gas you use, your utility company installs a meter between the main gas line and the distribution lines that send gas to various appliances in your home. A standard gas meter works by measuring the force of the gas that moves through the pipeline, and the dials on the meter move faster as the flow increases.
Every gas meter has many moving parts that enable it to do its job. If one of these parts isn’t working correctly, your gas meter could make strange noises or malfunction. For example, the natural gas that flows through your meter sometimes contains trace amounts of other gasses, which can damage the plastic parts inside your meter. The damaged parts can produce strange noises as the gas runs through the meter, like whistling or squeaking.
Solution: If you suspect something might be wrong with your gas meter, don't attempt to fix it yourself. Tampering with your gas meter is illegal in Florida. Instead, call your gas company to send out a technician to repair or replace the noisy gas meter.
Is your gas meter regulator whistling?
Again, if the whistling sound is coming from your gas meter, you might have a noisy gas pressure regulator (also called a meter regulator).
A meter regulator controls the flow of incoming gas to your meter. In short, it ensures your meter supplies your home with gas that flows at a reliable and constant pressure.
Although it can be alarming to hear whistling sounds coming from your meter regulator, it’s not usually a sign of a problem unless the smell of gas accompanies it. The sound can sometimes result from:
These changes cause a rubber piece inside the regulator called the rubber diaphragm to vibrate and, therefore, whistle.
Solution: Although a whistling meter regulator may not indicate a problem, it’s worth calling your gas company anyway, just in case. They can send a technician out to inspect it.
Is your gas line made from Corrugated Stainless Steel Tubing?
If you have a newer home, your gas appliances may receive their gas supply via flexible gas lines called Corrugated Stainless Steel Tubing (CSST). Any kinks or sharp 90-degree bends in these lines can cause something called “bottlenecking," a buildup of gas that creates vibrations in the gas line and produces a whistling sound. Even if there are no bends in the line, you might still hear whistling if the gas pressure is too high.
Solution: A licensed contractor can come to your home, inspect your gas lines, and correct any issues caused by bottlenecking or high gas pressure.
