When this is an actual emergency
Not every gas technician problem is a 2 AM call. These are the situations where waiting until morning costs more in damage than the after-hours premium costs in dispatch.
- Rotten-egg smell anywhere inside or outside the house.
- Hissing or whistling near a gas appliance, meter, or buried gas line.
- Carbon-monoxide detector alarm or symptoms (headache, nausea, dizziness affecting multiple occupants).
- Visible flame outside a furnace, water heater, or stove burner.
- Dead vegetation or bubbling mud over a buried gas line in the yard.

What to do while you wait
Four practical steps for the 30–60 minutes between calling and the truck arriving. Most of the damage in an emergency happens in this window — small actions matter.
- Get everyone (including pets) out of the house immediately — do NOT search for the leak source.
- Do not flip switches, light matches, use phones, or start vehicles inside the garage.
- From OUTSIDE the house, call Columbia Gas of Ohio at 1-800-344-4077 — they dispatch free for any suspected leak.
- Stay away until Columbia Gas confirms the building is safe — they will tag the appliance if it caused the leak.
When to call the utility company first
Columbia Gas of Ohio handles statewide natural-gas emergency response — 1-800-344-4077, 24/7, free. They will shut off your meter, find and tag the source, and ventilate the house. They do NOT repair appliances or piping inside the house — that is the licensed gas tech's job, scheduled after Columbia Gas clears the property. Duke Energy Ohio handles the same role in the Cincinnati / SW Ohio gas territory (1-800-543-5599); Dominion Energy Ohio / Enbridge Gas Ohio covers Cleveland metro and far-NE Ohio (1-877-542-2630).
Honest cost expectations for after-hours
Columbia Gas response is FREE — they would rather respond to a false alarm than miss a real leak. The licensed gas-tech repair afterward is the paid work. Common ranges: appliance gas-valve replacement $250–$500, flex line replacement $150–$350, full gas-line section repair $400–$1,200, CSST bonding fix $300–$700, gas-meter relocation (coordinated with Columbia Gas) $800–$2,500. After-hours premium adds $100–$200.
Reputable Ohio gas technicians disclose the after-hours premium BEFORE the truck rolls. A pro who refuses to quote the dispatch fee or service-call fee on the phone is the wrong choice for an emergency — call the next pro on your shortlist instead.
Frequently asked — emergency gas technicians
Why does Columbia Gas come out for free?
Public-safety mandate. Ohio regulates gas utilities through the Public Utilities Commission; emergency dispatch is part of the rate base every customer pays. Columbia Gas would rather pay for a false alarm than miss a leak that causes an explosion.
Is there a separate gas-tech license in Ohio?
No. Ohio handles gas work through the OCILB trades — plumbing contractors for gas piping, HVAC contractors for gas-fired appliances. 'Gas tech' on a ProFix profile is a specialty flag, not a separate license. Confirm OCILB at the Ohio eLicense Center before any repair.
Can I keep using the rest of the gas appliances if only one is leaking?
Columbia Gas will tag the leaking appliance and may shut off either the appliance valve or the whole meter, depending on the leak. Do not bypass a Columbia Gas red tag — the appliance is unsafe until the licensed tech fixes it and the utility confirms.
How do I know it's actually a gas leak and not just a stove I left on?
Both deserve a call. A stove left on (unburned gas) smells the same as a pipe leak because both have the same odorant. If the smell persists after you turn off all gas appliances at their valves, leave and call Columbia Gas.
Should I pay for a 'home gas-line inspection' upsell?
Be skeptical. Reputable gas techs inspect during normal service calls and tag specific issues with photos and pressure-test data. A door-to-door pitch for whole-house inspection in your neighborhood is usually a sales tactic — verify the company at /verify before paying.
