FirstCall Mechanical, backed by SkyKnight Capital, is one of the newest entrants in the commercial HVAC platform category — a company building a national commercial building services business through systematic acquisition of established commercial mechanical contractors. FirstCall appears in the CTC Acquisitions 2026 PE Roll-Up Tracker as an active commercial platform with verified acquisition activity, joining the growing list of commercial-focused platforms including Service Logic (Bain Capital + Mubadala), Impact Climate Technologies (Ardian), Crete United (Ridgemont), Astra Service Partners, and PremiStar (Partners Group).
SkyKnight Capital is a New York-based private equity firm that also co-invested in NearU Services alongside Freeman Spogli & Co. — the Southeast-focused residential home services platform covered previously in this publication. The two investments together — NearU (residential) and FirstCall Mechanical (commercial) — give SkyKnight exposure to both sides of the HVAC services market simultaneously.
The Commercial HVAC Platform Thesis
FirstCall Mechanical represents a specific commercial HVAC investment thesis that SkyKnight and its commercial-focused PE peers are executing in parallel: the commercial HVAC services market is less consolidated than residential, has characteristics that justify premium valuations (mission-critical demand, long-duration service contracts, building owner relationships), and is entering a demand acceleration driven by data centre construction and healthcare expansion that creates above-market growth potential.
The commercial HVAC platform thesis differs from residential in specific ways:
• Customer type: Commercial platforms serve building owners, property managers, and facilities managers rather than homeowners. Customer acquisition is relationship-driven rather than marketing-driven — the sales cycle is longer but produces more durable, higher-value contracts.
• Revenue model: Commercial service agreements are typically multi-year contracts covering preventive maintenance, emergency service, and repair — generating recurring revenue that is more predictable and higher-margin than residential replacement-driven revenue.
• Technical complexity premium: Commercial HVAC — large rooftop units, chillers, building automation integration, data centre precision cooling — is more technically complex than residential, creating barriers to entry that support premium pricing for qualified contractors.
FirstCall Mechanical, backed by SkyKnight Capital, is building a commercial HVAC platform through systematic acquisition of established commercial mechanical contractors — entering a commercial services market that is less consolidated than residential while benefiting from the data centre and healthcare construction demand that is generating above-market commercial HVAC growth in 2026.
SkyKnight's Dual-Track HVAC Strategy
SkyKnight's simultaneous investment in NearU Services (residential, Southeast-focused) and FirstCall Mechanical (commercial) is unusual among HVAC-focused PE firms. Most investors take either a residential platform approach or a commercial platform approach — the two markets have different customer types, operational models, and M&A execution requirements that typically don't combine efficiently in a single portfolio company.
By holding separate residential and commercial platforms, SkyKnight captures the structural growth in both segments — residential recovery from the current correction and commercial acceleration from the data centre wave — without attempting to combine operationally distinct businesses under a single roof. It is a portfolio-level view of the HVAC market rather than a single-platform investment.
