NEW YORK — Gamut Capital Management, a middle-market private equity firm, has signed a definitive agreement to acquire Airtron Heating & Air Conditioning, which designs, installs, and services HVAC systems, from NRG Energy Inc.

Airtron is one of the country’s largest installers of HVAC systems in new residential construction, with expansive geographic coverage across 13 metropolitan areas in Texas, the Midwest, and Mid-Atlantic regions. With a broad range of products and extensive service capabilities, Airtron also offers ongoing maintenance services, providing coverage to end customers for the duration of a system’s lifecycle, a press release from Gamut said.

Airtron had been acquired by NRG as part of its acquisition of Direct Energy in 2021. Notwithstanding its ownership by corporate organizations, Airtron has largely operated as an independent business, the press release said. Since 2019, Airtron has been led by Jeff Morrow, who will assume the position of CEO.

“We are proud of the progress we’ve achieved to reach this point. We would like to thank NRG for their partnership in positioning us for this next chapter, and we are excited to partner with Gamut to usher in a phase of accelerated growth,” Morrow said. “As a stand-alone business, we are fully dedicated to strengthening our customer and supplier relationships and are excited to enhance our service offerings through re-investment in the company.”

“We are excited to partner with Jeff and the Airtron team to further build on the market- leading, best-in-class HVAC platform that has been established over its successful history and strengthened under the ownership of NRG,” said Michael Hanigan, a partner at Gamut. “As a stand-alone organization, we are encouraged by the multiple avenues of growth available to both accelerate the business' evolution as a full-service provider of HVAC installation and maintenance offerings as well as further expand Airtron’s partnership capabilities with key home builders through strategic acquisitions.”
