Manual load calculations can consume most of a contractor’s day without the right technology. MiTek® Wrightsoft® software completes the same ACCA-compliant calculations in about an hour, freeing contractors to bid more projects and serve more customers.
“Partnering with ACCA empowers us to provide contractors with cutting-edge tools that exceed industry best practices,” says MiTek leadership. Since 1984, the company has developed HVACR design software that automates complex calculations while maintaining industry standards for accuracy and compliance.
Solving the time problem that limits growth
Engineer Bill Wright developed Wrightsoft after recognizing that ACCA manual calculations created a bottleneck for contractors who wanted to scale their operations. Wrightsoft became the first software to automate Manual J® calculations, establishing the foundation for modern HVACR design workflows.
Today’s Wrightsoft platform handles Manual J®, D®, and S® calculations for residential and commercial projects. The software produces precise load calculations and complete system layouts while ensuring designs meet ACCA methodology requirements.
Measurable impact on contractor productivity
One contractor’s experience demonstrates the difference: “I’ve always been a proponent of proper sizing of air conditioning equipment. For a standard 3,000 square-foot, 4-bedroom house, doing the load calculations manually would take many hours. Then I found Wrightsoft, and by using their RightJ and RightD, I was able to produce load calculations and duct design in about an hour.”
This time reduction allows contractors to complete more proposals, reduce customer wait times, and take on larger project volumes. Accurate calculations also minimize callbacks and ensure systems perform as designed, supporting long-term customer satisfaction.
Adapting to industry changes
As building codes evolve and heat pump installations increase, MiTek continues updating Wrightsoft to address new requirements and technologies. The software accommodates traditional HVACR systems and emerging technologies without requiring contractors to learn multiple platforms.
MiTek’s commitment to ACCA methodology ensures that designs remain compliant with industry standards regardless of regulatory changes or technological advances.
Expanding capabilities through integration
MiTek is investing in Building Information Modeling (BIM) integration to connect HVACR design with broader construction workflows. This development aims to improve collaboration between contractors, builders, and other trades while reducing costly miscommunications.
When design software integrates with project management and installation processes, contractors can deliver more consistent results while streamlining their operations from initial quote through final installation.
For contractors who need to balance design accuracy with operational efficiency, Wrightsoft provides the tools to accomplish both objectives without compromise.
