QuoteHagens Berman has filed a class-action lawsuit on behalf of consumers accusing seven of the nation's leading HVAC manufacturers of conspiring to fix prices of HVAC equipment, including air conditioner condensers, heat pumps, furnaces, air handlers, rooftop units, split systems, chillers and variable refrigerant flow systems. The lawsuit names Bosch, Trane, Carrier, Daikin, Lennox, Rheem and AAON as defendants stating they fraudulently concealed their conspiracy that began in the onset of the COVID-19 pandemic, obscuring their unlawful anticompetitive behavior amid supply chain disruptions. The class action accuses defendants of secret meetings, information sharing and more to drive the price of HVAC equipment to "historic levels."
Major brand names listed in the complaint include:
Bosch (including subsidiaries JC Residential and Light Commercial LLC and Johnson Control-Hitachi Air Conditioning North America LLC)
Trane (including subsidiary Mitsubishi Electric Trane HVAC US)
Carrier (including Viessmann Manufacturing Co.)
Daikin (including ThermalNetics LLC)
Lennox (including subsidiary Allied Air Enterprises LLC)
Rheem (including its division Heat Transfer Products Group LLC) and
AAON (including subsidiary BASX Inc.)
