Altman Air Conditioning, founded in 1985, is a commercial HVAC and mechanical services provider serving South Florida. The add-on strengthens Flow's Florida presence and complements Cortez, an existing Flow platform company serving commercial customers across the state. Altman will keep operating under its existing name while gaining access to Flow's broader technology and operational resources.

Quad-C invested in Flow Service Partners, a multi-region HVACR and plumbing services platform, in November 2024. Flow Service Partners, backed by Quad-C Management, has acquired Altman Air Conditioning, a commercial HVAC and mechanical services provider serving South Florida, for undisclosed terms. Founded in 1985, Altman brings more than four decades of commercial HVAC and mechanical services expertise to the Flow platform, having built a loyal customer base through responsive service for demanding commercial environments.

The deal complements Cortez, an established Flow Service Partners company serving commercial customers across Florida, and is intended to expand the services, expertise and resources available to customers of both companies. "Altman represents the qualities we value in a partnership: an experienced team, a strong market position and a proven history of serving complex commercial customers," said Jack Walker, partner at Quad-C. "This investment advances Flow's strategy of building density in attractive markets and supporting high-quality local operators with the capital and resources needed to grow.".
