On June 18, 2026, Lennox entered a definitive agreement to purchase Heat Controller from Platinum Equity. The deal includes the Comfort-Aire and Century brands and is expected to close later this year pending customary regulatory approvals, with financial terms remaining undisclosed.
The acquisition bolsters Lennox’s ability to serve small and mid-size HVAC distributors across North America by adding Heat Controller’s broad product portfolio and strong brand recognition. The deal is aimed at enhancing equipment availability, customer service levels and cross-selling opportunities within Lennox’s existing network.
This sale marks Platinum Equity’s final exit from its Motors & Armatures investment, following a prior divestiture of the MARS parts division for $650 million in 2025. Platinum Equity’s transformation efforts included strategic add-on acquisitions, cost-saving initiatives and leadership enhancements to maximize value before divesting Heat Controller.
