In Suwanee, a gas smell means leave the house first, then call 911 and Atlanta Gas Light at 877.427.4321 from outside. New appliance lines, repairs on your side of the meter and pressure tests are plumber work, so call the number on this page to be connected with a local plumber in Suwanee.

The Suwanee setup
The City of Suwanee's utilities page says it plainly: Atlanta Gas Light maintains the natural gas distribution system, and residents choose a certificated marketer. So the company on your bill may change, but AGL is always the one to call about a leak.
Suwanee's homes are young. Census survey data put the median build year at 2003, with only about 3% built before 1980. Most houses here use corrugated stainless tubing run to a manifold, often feeding two furnaces, a water heater, a range and a fireplace. The usual jobs are adding capacity for new appliances, fixing a leak at a manifold or connector, and confirming the tubing has its bonding wire to the electrical grounding.
The city requires permits for changes to plumbing systems and names water heater replacement as an example. Permits and inspections go through the city's online portal.
What kind of gas job is it?
| Job | What's involved |
|---|---|
| Replace a range or dryer connector | New listed connector and leak check |
| Add a gas range where there was electric | New branch, shutoff and pressure test |
| Switch to a tankless water heater | Load calculation, often a larger line, permit |
| Outdoor grill or fire pit | Buried or protected line, shutoff, test |
| Standby generator | Sizing for total load, possible meter upgrade |
Signs of a problem
- A rotten-egg smell. Get out and call from outside.
- Hissing at the manifold or behind an appliance
- Appliances that lose flame when others run
- Yellow flames or soot
- Bills rising without reason
Timing notes
Homes built in the early 2000s are now at the age when original water heaters and furnaces are being replaced, which is the natural time to rethink pipe sizing. Add-ons are easier when planned together. Generators and outdoor kitchens are often installed in spring; book ahead, as a meter upgrade from AGL may be part of the schedule.
Calling the number on this page puts you in touch with an independent local plumber who does gas work in Suwanee. Have a list of every gas appliance in the house and the one you want to add; with manifold systems, the plumber can often add a port rather than tapping into an existing branch, which keeps each appliance on its own supply and its own shutoff.
