Piedmont Service

What Piedmont Service does

Piedmont Service Group is a privately held HVAC mechanical services company headquartered in Raleigh, North Carolina, founded in 1971 as Piedmont Trane Air Conditioning. The company specializes in energy-efficient HVAC solutions, building automation, and facility performance services for commercial, industrial, institutional, and government clients across Virginia, North Carolina, and South Carolina, operating nine locally managed branch offices and leveraging the Service Logic national network for multi-location enterprise accounts. Its product portfolio centers on core HVAC services augmented by proprietary modules including Building Sentinel™ (analytics), Visual Intelligence (cloud-based service reporting), ThermaClear® (oil-fouling treatment), and the CMS Controls division (building automation integration supporting BACnet, LonMark, MODBUS, and major OEM protocols). Certifications include ENERGY STAR partnership, GSA Schedule 03FAC contractor status, and alignment with ASHRAE, UL, and ASTM standards.

The company's revenue model is a hybrid of recurring maintenance contracts, project-based design/build and retrofit work, planned equipment maintenance, and energy optimization professional services. Customer segments span commercial, industrial/manufacturing, mission critical facilities, healthcare, education, government, and retail, with named enterprise accounts including PNC Bank (100+ NC branches), Quintiles/IQVIA (LEED Silver HQ), Liberty Property Trust, Eagle Transport, and B/E Aerospace. The go-to-market is direct enterprise field sales through locally managed branches, supplemented by content marketing, case studies, industry affiliations (ASHRAE, BOMA, IFMA, AEE), and community involvement. Reported customer outcomes include 20% energy savings for Eagle Transport ($11,200 annual), 51% energy reduction for St. Francis of Assisi, and a 90% long-term client retention rate. The Kelly family has been central to ownership since Larry Kelly's 1972 purchase of the 8-employee firm; current leadership includes President Chris Turner and CFO Cristian Sanchez (joined 2025).
