Daikin Industries and its U.S. subsidiaries have been named as defendants in a lawsuit filed in the United States District Court for the Eastern District of Michigan on March 20, 2026. The case alleges that multiple companies conspired to artificially increase prices for HVAC equipment sold in the United States, potentially affecting purchasers since January 1, 2020.
The subsidiaries involved are Daikin Comfort Technologies North America, Inc. (Texas), Daikin Applied Americas Inc. (Minnesota), and Thermal-Netics LLC (Michigan). These entities were served with the complaint on and after March 30, 2026, while Daikin Industries itself has not yet been served but disclosed the case based on public docket information.
The lawsuit was filed by Alyssa Berg of Minnesota on behalf of a proposed nationwide class of HVAC equipment purchasers. The complaint seeks damages and other relief, although no specific monetary amount has been disclosed.
Daikin stated that if it is formally served, it will take appropriate action after analyzing the claims. The company added that it is currently difficult to estimate the potential impact of the lawsuit on its business results and will disclose further information if necessary.
