Gas work
Electrical, plumbing & HVAC

Gas lines and gas appliances

PRO JOB
Ranges, dryers, heaters, grills on natural gas.

Why this is a pro job

Gas work is licensed-trade work: a leak test, a permit and an inspection. Not a DIY job at any size.
Hire this out: licensed work with a permit.

How it goes

3 stages
1
Hire licensed
Licensed plumber or HVAC contractor, depending on the appliance.
2
Permit
They pull it; the town inspects.
3
Test
Pressure and leak testing before the appliance goes live.

What you can do yourself

Nothing on this one: it’s licensed work from start to finish. Use the questions below to compare contractors.

What to ask a contractor

•
Who pulls the permit?
•
Is the leak test and inspection included?
•
Does the line size cover every gas appliance at once?
These are the general rules. Your state, province or town may add its own: check with your local building department before you start.
Licenses and registration
Hire a plumber or HVAC contractor licensed for gas work where you live — states, and some cities, license them — who pulls the permit from your local building department, pressure-tests the line and has it inspected. A home improvement contractor’s registration doesn’t cover gas work. Rules change — your building department has the last word.

How to hire a licensed plumber or HVAC contractor

This is licensed work: only a licensed plumber or HVAC contractor should do it. Ask these questions and check the license before you sign.
Ask before you hire
•
Your license number? Look it up on your state’s (or city’s) licensing board website before you sign.
•
Will you pull the permit in your name and be there for the inspections?
•
Can I have the price and the scope in writing, with the license number on it?
Check the license
Look the license up with your state or local licensing board before you sign.
Permit and inspections
The plumber or HVAC contractor pulls the permit from your local building department, pressure-tests the line and has it inspected before the gas is turned on. Never use gas through a new line that hasn’t passed.
