Mainline Service is a family-owned and operated electrical and HVAC contractor that has served the Piedmont Triad region since 1965. Based in High Point, NC, the company provides reliable solutions for residential, commercial, and industrial clients across dozens of local communities. With nearly six decades of operation, Mainline Service has established itself as an integral part of the area's home service infrastructure.

Key Services for High Point Homes and Businesses

The company offers a comprehensive range of services tailored to the specific needs of the Piedmont Triad. For electrical work, this includes circuit breaker and electric panel installation and repair, which are common upgrades in the area's older neighborhoods like Oak Hill and Uptowne. Their expertise in wire and outlet installation addresses the needs of both historic homes and new developments in areas such as Palladio and Johnson Street.

HVAC services form another core component of their work. Given the region's humid summers and variable winters, system maintenance, repair, and installation are in constant demand. Mainline Service handles everything from routine check-ups for homes near Oak Hollow Lake to complete system replacements for commercial clients along the South Main Street corridor.

Specialized installations reflect modern local trends. Electric vehicle charging station installation supports growing adoption in communities like Jamestown and Kernersville. Generator installation provides backup power solutions important for homes in more rural parts of their service area like Stokesdale and Wallburg.

Areas Served Throughout the Piedmont Triad

Their extended service area covers a significant portion of central North Carolina, reaching residents and businesses in Winston-Salem, Salisbury, Thomasville, Statesville, Asheboro, and Kernersville.

The company's operational familiarity extends to dozens of additional communities, from Clemmons and Lexington to smaller towns like Denton and Pilot Mountain. This broad geographic knowledge allows their technicians to understand the varying infrastructure characteristics found across the region, from the brick ranch homes common in Archdale to the newer constructions in areas like Advance.
