Impact Climate Technologies (ICT), backed by Ardian — one of Europe's largest private equity firms — has been quietly building a national commercial HVAC platform through multiple acquisitions in 2025 and 2026. The most recent tracked deals include the acquisition of Heat Transfer Systems of Georgia (Alpharetta, GA) and Larry Wunsch & Associates (LWA) of San Antonio, Texas. ICT is a commercial HVAC holding company whose acquisitions are expanding its coverage from the Southeast into Texas.
Ardian is not a name most HVAC industry participants are familiar with — it is a French PE firm managing over $160 billion in assets with investments across infrastructure, private equity, and real estate globally. Its decision to build a US commercial HVAC platform through ICT is another data point in the story of global institutional capital recognising HVAC services as a premium, durable investment category.
Who Is Impact Climate Technologies?
Impact Climate Technologies is Ardian's vehicle for building a commercial HVAC services platform in the United States. The company focuses on commercial HVAC installation, maintenance, and service — targeting building owners, property managers, and institutional facilities operators that require reliable, technically sophisticated climate control for their facilities.
ICT's model aligns with the broader commercial HVAC roll-up thesis: mission-critical service demand, long-duration maintenance contracts, building owner relationships with multi-year retention, and geographic expansion through acquisition of established regional contractors with deep local market positions.

The Two Recent Acquisitions
• Heat Transfer Systems of Georgia (Alpharetta, GA): An Alpharetta-based commercial HVAC provider expanding ICT's Georgia presence in a market with significant commercial construction activity and data centre development. Alpharetta is part of the North Atlanta technology corridor where significant commercial HVAC demand — from tech companies, healthcare, and commercial real estate — is concentrated.
• Larry Wunsch & Associates (LWA, San Antonio, TX): A commercial HVAC and plumbing equipment representative and distributor serving San Antonio and the surrounding South Texas market. LWA will continue operating under its existing name and leadership while ICT provides strategic, operational, and sales resources to support growth and expand ICT's Texas presence.
Why Ardian Is in US Commercial HVAC
Ardian's decision to build a US commercial HVAC platform reflects several factors that make the US market attractive to European institutional investors:
• Market size and growth: The US commercial HVAC market is heading toward $70 billion by 2030 at above-average growth rates. For a fund managing $160 billion, allocating capital to a $70 billion growing market with premium service margins is a straightforward investment thesis.
• Fragmentation: The commercial HVAC services market is overwhelmingly served by independent regional contractors with no institutional ownership — exactly the consolidation opportunity that PE platforms exploit through systematic acquisition and platform value creation.
• European analogue: Ardian manages assets across European commercial building services markets where similar consolidation dynamics have played out. Its European experience provides a validated playbook for the US commercial HVAC consolidation cycle.
• Data centre tailwind: As in Europe, US data centre construction is the fastest-growing commercial HVAC demand driver. Ardian's infrastructure investment experience gives it particular conviction in the data centre demand thesis.
