About Us


MWSK was founded in 1974 under the name Millander-Wilke, Inc. In 1990, our name was changed to MWSK Equipment Sales Inc. to honor the founders and to allow the continuity of identity as owners are added or retire.


MWSK Equipment, Inc. markets and sells high quality and unique air conditioning, heating and energy conservation equipment.  Our sales engineers are graduate engineers with experience in the HVAC industry and the New York City HVAC market, ranging from eight to forty years.  We call on owners, mechanical engineers, construction managers and mechanical contractors in order to promote the sale of our products.  We work closely with design engineers to meet their design needs with our products as the basis of design.  We then follow up with the actual purchases, handle all technical and installation questions during the installation process and provide startup, in-warranty and maintenance services.
