How Can I Tell if My Furnace is Leaking Gas in Springfield, MA? Symptoms of Exposure & More

A gas furnace is a great and reliable source of warmth for many households, especially during colder months. While they are generally safe when maintained and operated correctly, there is always a potential risk of a gas leak. Recognizing the signs of a gas leak and knowing where they can occur can be the difference between safety and danger. Ambient Heating & Air Conditioning will share signs of a gas leak, and where they are most likely to occur.

What are the Symptoms of Gas Leak Exposure?

• Distinctive Odor: Natural gas is odorless, but for safety reasons, a scent is added to it, often described as a “rotten egg” smell. If you detect this scent around your furnace or within your home, it is a clear sign of a potential leak.
• Hissing or Whistling Sounds: A sound of hissing or whistling near the gas lines or the furnace itself can be another sign of escaping gas.
• Visible Dust or Dirt Near Gas Lines: If you observe dust or debris being blown or stirred up around the gas lines, it might be caused by the gas leak’s force.
• Dead Indoor Plants: A sudden and unexplained decline in the health of indoor plants can be a sign of increased levels of natural gas in the environment.
• Physical Symptoms: Exposure to a gas leak can cause dizziness, nausea, fatigue, and difficulty breathing. If you or your family members experience these symptoms suddenly, especially when the furnace is running, it might be due to a gas leak.
• Higher Gas Bills: A sudden spike in your gas bill without an increase in usage can hint at a gas leak, as more gas is lost to the environment.

Where is the Most Common Place for a Gas Leak?

• Gas Supply Line: The primary line supplying gas to your furnace is a common point where leaks might occur, especially at connection points or if the line itself gets damaged.
• Control Valve: The gas control valve controls the flow of gas into the furnace’s burner. Over time, wear and tear or defects can cause it to malfunction, leading to potential leaks.
• Pilot Light or Gas Burner: If the pilot light goes out frequently or the gas burner fails to ignite consistently, there might be a gas leak in these components.
• Heat Exchanger: The heat exchanger can develop cracks or holes over time, allowing gas to escape. While this is more common in older units, it is essential to monitor and maintain the heat exchanger’s integrity in all furnaces.
• Joints and Connections: Any point where components connect can become weak or deteriorate over time, making them potential sites for gas leaks.

What to Do If You Suspect a Gas Leak from Your Furnace

Turn off the main gas supply immediately and ensure adequate ventilation by opening windows and doors. Don’t switch on lights or any electrical appliances. Refrain from using phones within the house or any actions that could create a spark. It’s safer to vacate your home until professionals can assess the situation. Once you’re in a safe location, call emergency services or your gas company. Then, get in touch with a licensed HVAC technician to inspect, diagnose, and repair the issue. Scheduling regular furnace inspections can identify potential problem areas before they escalate into serious issues, reducing the risk of gas leaks.
