Software Ordering

eDesign Suite Software is available on a license basis. There is a first-year license fee and then renewal fees in subsequent years to keep the license active. Payment of the license fees entitles the licensee to use the software, to receive regular program updates and to receive technical support from our staff of HVAC engineers.
