Gas Leak Detection

What to Do Right Now If You Smell Gas

• Leave the building immediately — don’t stop to gather belongings
• Don’t operate any switches, lights, or electronics inside the home
• Don’t use your phone until you’re outside and away from the building
• Call 911 from outside, then SoCalGas at 1-800-427-2200
• Wait outside until SoCalGas confirms the meter has been shut off
• Once SoCalGas has made it safe to return, call HVAC Services Team for full leak inspection and repair

How Gas Leak Detection Works

A certified technician uses a calibrated combustible gas detector to scan every gas connection, fitting, appliance hookup, and pipe section in the home. When a leak is located, the exact pressure loss is confirmed with a manometer test before any repair work starts. All repairs are pressure-tested again after completion to confirm the line is fully sealed.

What Causes Gas Leaks in Simi Valley Homes

• Corroded or aging gas fittings — common in Simi Valley homes built before 1990 with black iron pipe
• Loose or failed appliance connections (stove, water heater, furnace, dryer)
• Shifting soil or tree root pressure on underground gas lines
• Deteriorated flexible connectors on gas appliances — these degrade over time and are often overlooked in older homes

After the Repair

Once the leak is sealed and pressure-tested, the technician checks the surrounding area for residual gas and confirms all appliances are reconnecting and firing safely. If the leak was near your furnace or heating system, a combustion check is also run to confirm nothing was affected during the outage.
