Wrightsoft's Right-Suite Universal is the long-standing gold standard for HVAC system design, combining ACCA-approved Manual J load calculations, Manual S equipment selection, and Manual D duct sizing into a single Windows-based platform. The flagship Right-Draw tool lets designers sketch or import floor plans and automatically propagates changes across every module.
Beyond core load calcs, Right-Suite Universal covers room-by-room analysis, zoning design, radiant and hydronic system layout, code compliance reporting, and equipment performance data from hundreds of manufacturers.
Acquired by MiTek Industries in 2017, Wrightsoft continues to invest in its duct-design automation and sales-close tools. Its depth of features makes it the reference software that other HVAC design tools are benchmarked against.
