Lennox Swallows NSI's HVAC Biz: £440 Million Deal

Lennox Swallows NSI's HVAC Biz: £440 Million Deal
Published:

Lennox International is set to bolster its climate control empire by acquiring NSI Industries' HVAC division in a move that has some old hands wondering if choice will soon be a thing of the past.

Lennox, a big noise in the climate control game, is stumping up $550 million – roughly £440 million at today's rates – to acquire NSI Industries’ HVAC division. This means Duro Dyne and Supco will soon be flying the Lennox flag. The acquisition, expected to close in the fourth quarter of 2025, is, as always, subject to regulatory approval.

According to Lennox, this purchase will create a "one-stop partner for the HVAC industry", offering a broader range of parts and supplies.

Bigger is Better?

Alok Maskara, CEO of Lennox, reckons this acquisition strengthens the firm's ability to deliver complete lifecycle solutions for residential and commercial customers, reinforcing their position as a one-stop partner for the HVAC industry. He added that adding brands like Duro Dyne and Supco responds to customer demands for a broader parts and supplies offering. Sounds like marketing guff to me.

Duro Dyne, billed as a market leader in HVACR components and accessories, and Supco, known for technician-focused HVACR parts, both operate manufacturing and distribution across the United States and Canada. The acquisition aims to complement Lennox’s existing product lines, offering more options for residential and commercial clients.

Team Spirit?

John MacQuarrie, President of NSI Industries HVAC, seems chipper about the transition, stating that his team members are excited to join Lennox. He believes the resources Lennox brings will help ensure their legacy of success, built over 70+ years by their team members and channel partners, continues. He believes the cultures of excellence and innovation will yield greater benefits, which is always nice to hear; although, I'll believe it when I see it.

The official line is that this acquisition will benefit customers with more integrated solutions. Lennox is clearly betting on synergy and economies of scale, which sounds grand on paper.

The proof, as always, will be in the pudding. Will this lead to genuine innovation and better service, or simply fewer independent suppliers and higher prices down the line? Only time will tell if this move strengthens Lennox’s hand or just makes the game less interesting for everyone else. More information about the acquisition can be found at investor.lennox.com.
