Lennox to acquire HVAC Division of NSI Industries
18th August 2025
USA: Lennox has signed a definitive agreement to purchase the HVAC division of NSI Industries, a leading provider of electrical, HVAC, and network infrastructure product solutions, for approximately $550m.
NSI Industries’ HVAC platform includes Duro Dyne, Supco, and other leading component and accessories brands.
According to Lennox, the acquisition from Sentinel Capital Partners enhances the company’s ability to deliver a comprehensive, integrated portfolio of parts and supplies across North America.
Established in 1975, and based in Huntersville, North Carolina, NSI Industries was acquired by Sentinel Capital Partners in 2022.
“This acquisition strengthens our ability to deliver complete lifecycle solutions for residential and commercial customers and reinforces our position as a one-stop partner for the HVAC industry,” said Lennox CEO Alok Maskara. “By adding trusted heritage brands including Duro Dyne and Supco into our portfolio, we are responding to the needs of our customers who have asked for a broader parts and supplies offering.”
The acquisition is expected to close in the fourth quarter of 2025, subject to regulatory approvals.
