Partners Group, a global private markets firm, announced on August 10, 2026, that its two US-based HVAC portfolio companies, DiversiTech and PremiStar, have experienced substantial growth since their acquisition in 2021, driven by rising demand for cooling solutions amid extreme weather conditions. 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. Both companies have delivered impressive EBITDA growth, with compound annual growth rates of 14% and 22%, respectively.
The strong financial performance reflects broader tailwinds in the US HVAC market. Increasingly frequent extreme weather events are highlighting the critical role of HVAC system maintenance in maximizing unit performance and efficiency. Additionally, the rapidly aging installed base of HVAC units, the push for more energy-efficient upgrades, and the rise of building automation solutions are further fueling demand for both parts and services. These factors create a favorable environment for companies like DiversiTech and PremiStar, which are essential to helping communities and enterprises adapt to changing climate conditions.
Partners Group has leveraged its investment platform to identify and implement best practices across both portfolio companies, driving transformational value creation plans. These plans include investments in operations, supply chains, and technology, as well as executing selective add-on acquisitions to expand capabilities and market reach. This disciplined approach has enabled organic, sustainable growth, positioning the companies for continued success.
Wolf Scheider, Head of Private Equity at Partners Group, commented, "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 implications of this growth extend beyond the companies themselves. For businesses and property owners, the increased demand for HVAC services underscores the importance of regular maintenance to ensure systems operate efficiently, especially during extreme weather. For the industry, it signals a robust market for HVAC parts, services, and upgrades, driven by regulatory pressures for energy efficiency and technological advancements. For investors, it demonstrates the potential of private equity to capitalize on climate-related trends and generate strong returns through operational improvements.
Partners Group, with approximately 2,000 professionals and over $186 billion in assets under management globally, continues to focus on identifying attractive investment themes and transforming businesses into market leaders. The success of its HVAC portfolio companies exemplifies its operationally oriented approach and its ability to navigate changing market dynamics. As extreme weather events become more common, the demand for cooling solutions is likely to persist, providing ongoing opportunities for growth in this sector.
