Kelso Industries

Kelso Industries is an American partnership platform that acquires and supports local HVAC, mechanical, electrical and plumbing (MEP+) companies. Founded in 2021 by childhood friends Steve Carroll and Steven Nicholson, the group operates more than 30 companies nationwide, employs over 3,500 people and reports annual revenue in excess of $1.2 billion.

Each operating company keeps its own name, brand and local relationships, while drawing on the platform's collective resources: enhanced buying power, leadership development programmes and access to national-scale capabilities. Acquired firms cover heating, ventilation and air conditioning, mechanical services, electrical work and plumbing, serving customers through local expertise backed by the wider group.

For employees, the arrangement is intended to widen career paths and provide training and development within a family-of-companies structure. Kelso states core values of partnership, innovation, excellence and safety, and emphasises deepening customer relationships alongside the preservation of each business's legacy. Business owners joining the platform are able to transition their careers while creating new opportunities for their staff.

The company operates across the United States and describes itself as a preferred MEP+ solutions partner, delivering combined heating, ventilation, air conditioning, mechanical, electrical and plumbing services.
