Partners Group, a global private markets firm, announced on August 10, 2026, that its two US HVAC portfolio companies, DiversiTech and PremiStar, have experienced substantial growth since their acquisition in 2021. DiversiTech, a manufacturer and distributor of HVAC parts and supplies, has seen revenues increase by 60%, while PremiStar, a commercial HVAC services provider, has doubled its revenues over the same period. This performance underscores the robust demand for cooling solutions amid rising temperatures and other market dynamics.
The growth is attributed to several tailwinds in the US HVAC market. The increasing frequency of extreme weather events has heightened the importance of HVAC system maintenance to maximize performance and efficiency. Additionally, the aging installed base of HVAC units, the push for more energy-efficient upgrades, and the adoption of building automation solutions are driving demand for both parts and services. These factors have contributed to EBITDA growth of 14% CAGR for DiversiTech and 22% CAGR for PremiStar.
Partners Group has leveraged its investment platform to identify and implement best practices across both companies, focusing on transformational value creation plans. These plans include investments in operations, supply chains, and technology, as well as executing selective add-on acquisitions to support future growth. Wolf Scheider, Head of Private Equity at Partners Group, noted, "Across our HVAC portfolio, we are seeing organic, disciplined growth. As heat waves become a defining challenge of how we live and work, demand for HVAC parts and maintenance is rising. Our portfolio companies are essential to helping communities and enterprises adapt to these conditions, with meaningful growth runway ahead as value creation initiatives mature."
The strong financial performance of DiversiTech and PremiStar reflects broader trends in the HVAC industry, where climate change and regulatory pressures are reshaping demand. With extreme weather becoming more common, the need for reliable cooling systems and their maintenance is critical. This positions Partners Group's portfolio companies to capitalize on long-term growth opportunities, as they provide essential services that help society adapt to a warming world.
