Carrier offers a family of HVAC System design/engineering software products called eDesign.

eDesign contains a collection of programs created specifically for the HVAC system designer. These programs are crafted to increase productivity and accuracy, improve analysis capabilities and job documentation, and add a level of "marketability" to a designer's estimates.

Individual programs are available to assist in heating & cooling load estimating, annual building operating cost estimating and economic life cycle analysis.

The eDesign programs are written by HVAC systems engineers for HVAC systems engineers, and are supported by more HVAC system engineers with years of field application experience.
