Gas Leak Repair and Services for HVAC, Boiler, and Water
Gas Leak Repair & Services for HVAC in Greater Vancouver
A gas leak is the one HVAC fault you should never wait on. Natural gas lines feed furnaces, boilers, water heaters, and fireplaces throughout Greater Vancouver homes, and a leak at any fitting, valve, or connector is both a fire risk and a carbon-monoxide risk. ROMA Heating & Cooling’s gas-licensed (TSBC) technicians have located and repaired gas leaks across the Lower Mainland since 1999. This page explains what to do right now if you smell gas, what causes leaks, and how we find and fix them safely.
If you smell gas, act first and read later. Once the area is safe, call (604) 704-0300 for licensed gas leak diagnosis and repair.
If You Smell Gas — Do This First
Natural gas is given a sulphur, rotten-egg odour so you can detect it. If you smell it indoors:
- Do not use anything that could spark — light switches, appliances, garage doors, or phones inside the home.
- Do not light matches, candles, or the stove.
- Open doors and windows on your way out if it is safe to do so.
- Leave the building and keep others away.
- From outside, call FortisBC’s 24-hour emergency line at 1-800-663-9911, or 911 if there is immediate danger.
- Once the area is confirmed safe, call a licensed technician to find and repair the source.
Common Sources of HVAC Gas Leaks
Most leaks we find trace back to a small number of failure points along the gas train:
- Corroded or loose pipe fittings — threaded joints and unions loosen or corrode over time, especially in older homes and damp basements.
- Failing flexible connectors — the flexible appliance connector behind a furnace, range, or water heater can crack or work loose.
- Faulty gas valves — a worn or sticking gas valve on a furnace, boiler, or water heater can leak by.
- Cracked manifolds or burners — heat cycling can stress the burner assembly and manifold.
- Disturbed joints after renovations — work near gas lines can loosen connections that were previously sound.
Warning Signs of a Gas Leak
| Warning Sign | What It Often Indicates |
|---|---|
| Rotten-egg / sulphur smell | Escaping natural gas — act immediately |
| Hissing near a gas line or appliance | A leak at a fitting, valve, or connector |
| Higher-than-normal gas bills | Possible slow, ongoing leak |
| Dead or dying houseplants near a line | Gas displacing oxygen at the soil/area |
| Headaches, nausea, or dizziness indoors | Possible combustion gases / carbon monoxide — leave and call |
| Yellow (not blue) burner flames, soot | Incomplete combustion — have the appliance checked |
A gas leak and a carbon-monoxide problem can occur together. Working CO alarms on every level of your home are an essential backup to your senses.
How ROMA Detects and Repairs Gas Leaks
Finding a leak is precise work, and guessing is not safe. Our process:
- Detect — we use calibrated electronic gas detectors and a leak-test solution along fittings and connectors to localise the leak.
- Pressure-test — where needed we isolate and pressure-test the gas line to confirm where it is losing tightness.
- Repair — we remake or replace the failed fitting, connector, or valve to code, using the correct components for your appliance.
- Verify — we re-test the line for tightness, check appliance combustion, and confirm safe operation before we leave.
Gas Services We Provide
Beyond emergency leak repair, our gas-licensed technicians handle the full range of residential gas work:
- Gas line installation, extension, and relocation for furnaces, boilers, water heaters, ranges, fireplaces, and BBQ/outdoor lines.
- Gas appliance connections and disconnections during installs and renovations.
- Gas valve and flexible-connector replacement.
- Combustion and safety inspections, including CO testing on heating appliances.
Carbon Monoxide: The Hidden Risk of a Gas Fault
Not every gas hazard has a smell. Incomplete combustion in a furnace, boiler, water heater, or fireplace can produce carbon monoxide (CO) — a colourless, odourless gas. Because you cannot detect CO with your senses, it is essential to know the warning signs:
- Symptoms that ease when you leave the house — headaches, dizziness, nausea, or fatigue that lift outdoors and return inside.
- Yellow or flickering burner flames instead of crisp blue, plus soot or scorching around an appliance.
- Excess condensation on windows near a gas appliance.
- A CO alarm sounding — never ignore it; evacuate and call for help.
Fit CO alarms on every level of your home and near sleeping areas, and have your gas appliances inspected annually. If a CO alarm sounds, treat it like a gas leak: get everyone out and call for emergency help.
How to Prevent Gas Leaks and Combustion Problems
Most gas faults are preventable with routine care:
- Annual appliance servicing — we inspect connections, valves, burners, and combustion on your furnace, boiler, water heater, and fireplace.
- Use licensed technicians for any gas work — renovations and DIY connections are a frequent source of leaks; gas-fitting must be done to code by a TSBC-licensed technician.
- Keep appliance areas clear and ventilated — never store solvents or combustibles near a gas appliance, and keep combustion-air openings unobstructed.
- Replace ageing flexible connectors — older connectors behind ranges and water heaters can crack; we replace them with current-rated connectors.
- Maintain working CO and smoke alarms — test them regularly and replace them at the manufacturer’s stated interval.
Why Gas Work Must Be Done by a Licensed Technician
In British Columbia, gas-fitting is regulated work that must be carried out by a TSBC gas-licensed technician — and for good reason. Beyond the legal requirement, three things separate a safe gas repair from a dangerous one:
- Correct diagnosis — a calibrated detector and a verified leak test find the true source, instead of chasing a smell to the wrong fitting.
- The right components, installed to code — connectors, valves, and pipe sized and joined correctly for the appliance and the load.
- A confirmed tightness test — the line is pressure-tested after the repair and the appliance’s combustion is checked, so you know it is genuinely safe, not just no longer smelling.
Our technicians are gas-licensed and insured, and every gas repair we complete is verified for tightness and safe combustion before we leave the property.

Frequently Asked Questions
What should I do if I smell gas in my home?
Treat it as an emergency. Do not light flames, switch lights or appliances on or off, or use your phone indoors. Open doors and windows if you can do so safely, leave the building, and from outside call FortisBC’s 24-hour emergency line at 1-800-663-9911. Once the area is made safe, call a licensed technician to find and repair the source.
What causes a gas leak in HVAC equipment?
Common sources are corroded or loose gas-line fittings, a failing flexible connector at the appliance, a faulty or worn gas valve, a cracked manifold or burner, and joints disturbed during renovations. Older homes and DIY connections are frequent culprits.
How do you find a gas leak?
Licensed technicians use calibrated electronic gas detectors and a leak-test solution on fittings, then pressure-test the line where needed. We isolate sections to pinpoint the exact leak rather than guessing, and confirm the line is tight after the repair.
Is a small gas smell really dangerous?
Yes. Natural gas is explosive in the right concentration and incomplete combustion can produce carbon monoxide. Even a faint, persistent gas smell should be investigated immediately — never wait to see if it gets worse.
Do I need a licensed technician to repair a gas line?
Yes. In British Columbia, gas-fitting work must be done by a TSBC gas-licensed technician. Beyond the legal requirement, proper diagnosis, parts, and a verified tightness test are what actually keep your home safe.
