Gas Installation Service
Licensed Gas Installation Service in Swannanoa
O’Sheas Plumbing runs new gas and propane lines and connects gas appliances in Swannanoa and Black Mountain.
New Gas Line or a Gas Appliance Hookup?
Ian’s NC Plumbing Class I Contractor license, L.34576, covers our gas installation service in Swannanoa, and the work is insured. Before the new appliance is bought, it’s worth settling whether you need a new run or a hookup to the line you’ve got.
Start at the spot where it’ll go. A capped gas stub there means a gas appliance hookup could be all it takes. That only holds if the line behind the cap can feed the new appliance with everything else on it running. Where no pipe reaches, or the one that does is too small, you’re looking at gas line installation instead. We put in new gas lines and propane lines, and we connect gas appliances to lines that are already there.
Sizing the line against everything it already feeds is easy before the cooktop arrives and a real headache after it’s installed. Put a gas cooktop or gas dryer on a line too small for the total load, and its flame runs low whenever the furnace fires.
Natural Gas or Propane at Your Address
What fuels the house now decides the parts and the route, because each gas appliance is set up to burn one fuel. A range built for natural gas needs its conversion parts before it’ll run on propane, and the same goes the other way.
Not sure which one you’ve got? The house usually shows you:
Where there’s no gas main on your road, propane is the fuel, and the tank goes where a delivery truck can reach it. That isn’t always close to the house, so we handle the propane line installation from the tank to each appliance.

Adding a gas range, dryer or grill? Call, and we’ll check that the line can carry it with everything else that runs on gas.
Trouble on a Gas Line You Already Have
Maybe the line’s acting up, or you’ve stopped trusting it since a remodel. Either way, we start with gas leak detection to find any spot where gas is getting out, then move on to gas line repair. Swap out a fitting on a hunch, and the real leak can still be somewhere else on the line.
An older house can have a gas line that grew a branch at a time, and Kimberly Woods homes were typically built between 1960 and 1980. Before another appliance goes on, the line gets traced and tested, so any weak fitting shows itself before the new one’s lit.
Gas Runs Up Hills and Around Roots
The meter or tank and the appliance can sit on different levels on a mountaintop lot like those at Deer Run Estates. The run climbs between them in black iron pipe or CSST, with every joint and the gas shutoff valve left within reach. The whole run gets tested before the appliance is lit, and Ian’s on site for that test and for the first flame.
Big lots mean long gas runs, and most lots in Wildcat Cliffs cover between 1 and 5 acres. A longer run delivers less gas at the far end, so the pipe’s sized for its length and total load before a trench is dug.
A buried line to a grill, fire pit or standby generator pad crosses ground full of roots in Buffalo Mountain’s wooded yards. The route bends around the big ones, and buried utilities get marked through NC 811 before a shovel’s in the ground.
As the licensed plumber on the job, Ian gets the permit for the gas work. Have the appliance’s model and its spot picked out when you call (828) 348-5820, and Sarah takes it down for Ian, Sundays included.

Did you know?
The first gas company in the Americas was the Gas Light Company of Baltimore, incorporated by Rembrandt Peale on June 17, 1816. Its first gas streetlamp wasn’t lit until February 7, 1817, at North Holliday and East Baltimore streets.
FAQs About Gas Installation Service in Swannanoa
Being careful about gas is the right instinct, and we’d rather answer a question early than fix a guess later. Don’t see what you’re looking for? Ask a question here.
A gas line’s cost follows the length and route of the run, how many appliances it feeds and the pipe size that load needs. Tying into an existing line takes less work than a new run off the meter or propane tank. Crawl space runs are simpler than routes through finished walls or an outdoor trench. Every new line also gets a pressure test before it’s put in service.
Yes. A gas line split tees off an existing line and extends a new branch to the kitchen, sized for the added load. A South Asheville customer had Ian split off the line feeding the furnace and extend it to a new gas cooktop. He called it “our favorite upgrade in our house.” The line gets a pressure test before the cooktop is connected.
Black iron pipe is rigid threaded steel, the traditional choice for gas lines and still common in basements and exposed runs. CSST is flexible corrugated stainless tubing that routes through walls and crawl spaces with fewer joints. Code requires CSST to be tied into the home’s electrical grounding. O’Sheas Plumbing picks the pipe that fits the route and the appliance load.
If you smell gas in your Swannanoa home, leave the house first, without flipping switches or using anything that could spark. From outside, call your gas utility or 911. Once the utility has made it safe, call O’Sheas Plumbing at (828) 348-5820 for the repair on your side of the meter. Gas leak detection and gas line repair fall under Ian’s NC plumbing license.
You need someone licensed for fuel piping. The NC plumbing board includes fuel piping privileges in its plumbing and heating licenses, and it issues a separate Fuel Piping license for people without one. Ian’s gas line work in Swannanoa falls under his Plumbing Class I Contractor license, L.34576. Ask any installer which license covers their gas work, then look it up on the board’s site.
A proper gas appliance hookup includes a shutoff valve at the appliance and a new flexible appliance connector. A sediment trap goes in where code calls for it. Each joint gets a leak test before the gas range, gas dryer or water heater runs. Older homes may need the line extended first.
O’Sheas Plumbing pressure tests new gas piping in Swannanoa before any appliance is connected. The line is capped, pressurized and watched on a gauge or manometer for any drop. A loss means a leak, which gets found and fixed before the test is repeated. Only then does the gas get turned on and each appliance get lit and checked.
Yes. O’Sheas Plumbing installs propane lines to standby generators, ranges, dryers and water heaters around Swannanoa. The run is sized for the generator’s full load, with a shutoff valve at the unit. Ian handles the gas piping, while the generator’s wiring and transfer switch belong to an electrician.
A sediment trap, sometimes called a drip leg, is a short capped pipe below the appliance connection. Debris and moisture in the gas drop into it instead of reaching the appliance’s controls. Code calls for one on many gas appliances, and they’re often missing on older installs. O’Sheas Plumbing adds one when a Swannanoa hookup lacks it.
Your gas utility owns and services the meter and the regulator at it. Piping and appliance connections past the meter are work for a licensed plumber. The Asheville-area gas utility changed ownership in 2024, so check a recent bill for the right name and number. For gas line repair on your side, call (828) 348-5820.
