McQuay International

McQuay International

McQuay International is a global corporation that designs, manufacturers and sells heating, ventilation and air conditioning (HVAC) products, systems, parts and services for commercial buildings. Since 2006 McQuay has been a subsidiary of Daikin Industries, Ltd.

McQuay world headquarters are located in Minneapolis, MN, USA. Products are sold by a global network of sales representatives and distributors.



McQuay was incorporated in 1933 with manufacturing and headquarters in Minneapolis, MN. Initial success was built on the first classroom unit ventilator and the first hermetic compressor for air conditioning use.

During 1941-1945 McQuay manufacturing facilities were converted to support the U.S. war effort. In the later 1940s and 1950s, McQuay products and sales grew as the demand for commercial air conditioning increased. U. S. manufacturing facilities were expanded to meet this demand.

McQuay became a multi-national corporation during the 1960s by beginning overseas sales and licensing operations in Canada, England, Scotland, and Australia. In 1965, McQuay established a new division in Italy, McQuay Europa, to manufacture 50 Hz equipment.

Through mergers and acquisition in the 1970s, ‘80s, and ‘90s the McQuay product line grew to include more types of commercial HVAC and large capacity equipment, as air conditioning became viewed more as a requirement than a luxury in buildings of all types.

In 1992 McQuay received the Stratospheric Ozone Protection Award from the U.S. Environmental Protection Agency in recognition of McQuay being the first to design and manufacture chillers with HFC-134a, a refrigerant with no ozone depletion potential.[1]

In 2006 McQuay was acquired by Daikin Industries, a global manufacturer of both commercial and residential air conditioning equipment based in Osaka, Japan. Daikin had annual sales of $13 billion dollars in 2009.[2]

Daikin was named one of the 100 most sustainable corporations for three years in a row by Corporate Knights, Inc., from 2007 through 2009.[3]

In 2010 McQuay acquired HydroKool LLC of Phoenix, Arizona, a designer and manufacturer of pre-packaged, pre-engineered custom HVAC solutions.[4]

In 2010 the Daikin and McQuay Applied Development Center was certified as LEED Gold.[5]
