In 1985, while conducting a graduate HVAC seminar at the Massachusetts Institute of Technology (MIT), Bill Wright entered into a partnership with the Air Conditioning Contractors of America to design software for HVAC Manual J load calculations. As the original technical software partner of ACCA, Wrightsoft Corp became the first HVAC software company to create a computerized version of their Manual J, Manual D, and Manual N calculation methods. The Air Conditioning Contractors of America and Wrightsoft released the very first Manual J Load calculation software (Right-J) in February 1986. Corporate Logos
