Local Service
Serving All of Lavaca
Lavaca sits along Highway 96 just north of Highway 22, east of Barling and Central City on the way to Charleston, with the Arkansas River to the north and the Fort Chaffee training land to the west. Our trucks work the Highway 22 corridor east of Fort Smith most weeks: the neighborhoods in town around Main Street and Lavaca High School, the newer homes on the edges of town, and the rural places on the county roads out toward Central City, Charleston, and the river.
Lavaca equipment works hard — long humid summers, cold snaps and the occasional ice storm, and a mix of older brick ranches, farmhouses, mobile homes, 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 Lavaca
- In-town neighborhoods around Main Street and the Lavaca schools
- Newer homes and subdivisions on the edges of town
- Properties along Highway 96 and out Highway 22 toward Charleston
- Farms, shops, and rural homes on the county roads toward Central City and the Arkansas River
- Quick runs to Barling, Fort Smith, Charleston, and Greenwood
Lavaca is a short drive east of Fort Smith and Barling — our crews are on that side of the river most days, so it is a regular part of the route, not a special trip.
