Ohio is our launch state, so it's the one place where we can show the full depth — a ranked Ohio pro list, a public-permit leaderboard, state-licensing detail, and real Ohio cost guides. Treat everything in this section as an Ohio example of how ProFix verifies a trade, not as a national claim. We're building this same depth out state by state.
Hiring checks for Ohio gas technicians
- There is no separate ‘gas tech' license in Ohio — gas piping is handled by OCILB plumbing contractors, gas-fired appliances by OCILB HVAC contractors.
- Any gas smell is a 911-equivalent: leave the house, call Columbia Gas of Ohio at 1-800-344-4077 from outside, then schedule the trade repair.
- Combustion-analyzer reports + manometer readings + CO testing belong on any combustion-safety scope.
- Use the ProFix Trust Score to weigh OCILB license + permit pulls + recency rather than relying on stars alone.

Frequently asked: Ohio gas technicians
Is there a separate ‘gas tech' license in Ohio?
No. Ohio handles gas work through the OCILB trades that already cover it — plumbing contractors for gas piping and HVAC contractors for gas-fired appliances. ‘Gas tech' on a ProFix profile is a specialty flag, not a separate license.
Who do I call if I smell gas?
Leave the house. Call Columbia Gas of Ohio at 1-800-344-4077 from outside (most of Ohio) or Duke Energy at 1-800-634-4300 (Hamilton County / Cincinnati). 911 is appropriate for fire or unconscious people. Once the utility has confirmed the leak is mitigated, schedule the licensed trade for the repair.
What documentation should a gas job include?
Combustion-analyzer printouts, manometer readings, CO testing at the appliance and in the living space, and the permit and inspection record where the local building department requires one. Combustion safety is documentable — if the contractor cannot show the numbers, that is a red flag.
Do I need a permit for a gas-appliance hookup?
Usually yes. Water heater, furnace, range, dryer, and gas-fireplace hookups typically require a permit in Ohio metros. The local building department is the final authority. ProFix lists the permit office and phone on every metro page so you can confirm before booking.
Hand the question to your preferred assistant — it will use ProFix Directory's open MCP server and llms.txt as context.
