Your Guide to Safe and Reliable Home Gas Systems
Heritage Home Service is proud to serve homeowners across New Hampshire, Maine, and Massachusetts with trusted plumbing, HVAC, and electrical expertise — including professional gas line services. Natural gas is a clean and efficient energy source for heating, cooking, and hot water, but it must be handled with the highest level of care.
Understanding the basics of your home’s gas system and knowing how to spot warning signs can keep your household safe and prevent dangerous emergencies.
How a Residential Gas System Works
While each home’s setup varies, most natural gas systems follow a similar structure:
- Gas Supply Line: Natural gas is delivered to your property through a buried utility line or a propane tank system.
- Gas Meter & Regulator: The gas passes through a meter, which tracks usage, and a regulator, which ensures consistent pressure entering your home.
- Main Gas Shutoff Valve: Located near the meter or tank, this valve allows the gas supply to be turned off during emergencies or repairs.
- Interior Gas Piping: From there, gas travels through a network of interior pipes that supply appliances like furnaces, water heaters, dryers, stoves, and fireplaces.
- Appliance Connectors & Valves: Each appliance has its own shutoff valve and flexible connector.
This system operates under low pressure but requires precise installation and regular maintenance to remain safe and efficient.
Common Gas Appliances in New England Homes
Natural gas and propane are widely used across New Hampshire, Maine, and Massachusetts for:
- Home heating — furnaces, boilers, and space heaters
- Water heating — tank and tankless units
- Cooking appliances — ranges, ovens, and outdoor grills
- Fireplaces and gas log sets
- Backup generators
Because gas lines often run through basements, crawl spaces, or exterior walls, they can be vulnerable to wear, corrosion, or accidental damage over time — especially in older homes.
Recognizing the Warning Signs of a Gas Leak
A gas leak is a serious emergency. If you ever suspect a leak, leave your home immediately and call your gas company or 911, then contact Heritage Home Service for inspection and repair.
Common signs of a gas leak include:
- Distinct “rotten egg” odor: Utility companies add mercaptan, a sulfur-like scent, to help detect leaks quickly.
- Hissing or whistling sounds near gas lines or appliances.
- Dead or discolored vegetation above buried lines.
- Unexplained increase in gas bills indicating continuous leaks.
- Dizziness, headaches, or nausea experienced indoors.
Do not attempt to find or fix the leak yourself. Avoid using light switches, phones, or any electronics inside the home — sparks could ignite escaping gas.
Preventing Gas Line Problems
Routine inspections and smart habits are the best defense against gas emergencies. Heritage recommends:
1. Annual Professional Inspections
A licensed technician should check for corrosion, loose fittings, damaged connectors, or aging pipes at least once a year.
2. Know Where Your Shutoff Valve Is
Every homeowner should know the location of the main gas shutoff and how to operate it safely in an emergency.
3. Keep Areas Around Gas Lines Clear
Avoid storing boxes or flammable materials near gas meters, regulators, or appliance connections.
4. Be Cautious During Home Projects
Drilling or nailing into walls, digging in your yard, or remodeling can damage hidden gas lines. Always call 811 before digging and work with qualified professionals on interior renovations.
5. Upgrade Aging Gas Piping
Older black iron or steel pipes can corrode over time. Replacing them with modern, code-compliant materials improves safety and performance.
The Importance of Professional Gas Line Service
Unlike many other home maintenance tasks, gas line installation and repair should never be a DIY project. Mistakes can have catastrophic consequences.
Heritage Home Service’s licensed technicians are trained to:
- Install new gas lines for appliances, additions, or outdoor kitchens
- Repair or replace damaged piping safely and up to code
- Perform pressure tests to check for leaks or irregularities
- Re-route or upgrade old gas lines in older New England homes
- Install gas shutoff valves and regulators to meet modern safety standards
We handle every job with precision, ensuring your home’s gas system operates safely and efficiently.
Real-World Example: A Close Call in Portland, ME
Earlier this year, a homeowner in Portland, Maine, called Heritage after noticing a faint sulfur smell near their furnace. Our technician arrived the same day and found a corroded connector that had begun leaking near the shutoff valve.
We immediately shut off the gas, replaced the connector, pressure-tested the entire system, and restored service — all within a few hours. Catching the issue early prevented what could have been a dangerous situation.
