Local Service
Serving All of Charleston
Charleston is one of Franklin County’s two county seats, sitting on Highway 22 east of Barling and Fort Smith where Highway 217 crosses through town. Our trucks run that Highway 22 corridor every week: the neighborhoods in town near Charleston Public Schools and Main Street, the homes along Highway 22 back toward Barling, and the rural places on the county roads toward Lavaca, Branch, and Paris.
Franklin County equipment works hard — long humid summers, cold snaps and the occasional ice storm, and a mix of older farmhouses, brick ranches, and newer builds. We work on all of it: central systems, heat pumps, mini-splits, package units, and commercial equipment, with fully stocked service trucks and technicians licensed in both states.
Where we work in and around Charleston
- In-town neighborhoods near Charleston Public Schools and the Main Street business district
- Homes along Highway 22 toward Barling and Fort Smith
- Properties along Highway 217
- Farms, shops, and barndominiums on the county roads toward Lavaca and Branch
- Quick runs to Lavaca, Barling, Greenwood, and Paris
Charleston is a straight shot east of Fort Smith on Highway 22 — a regular run for our crews, not a special trip.
