Grading the Installation of HVAC Systems In the past, certified RESNET HERS® Raters had to rely on the nameplate data of an HVAC system in calculating the efficiency of a home. It is generally understood that in many instances the HVAC system is not installed per the manufacturer’s specification. This means that far too often the home’s HVAC did not perform as efficiently as the rating indicated. This has all changed with the adoption by ANSI of the RESNET/ACCA/ICC Standard for Grading the Installation of HVAC Systems. The standard sets a realistic level of the performance of an HVAC system in the reference home and awards the increased performance of a system based upon the inspection and testing of the system by a certified RESNET HERS® Rater. Grade I installation could reduce HERS® Index Scores by as much as 6 points! (depending on climate zone) Achieving a Grade I installation is also credited in the qualification of a home for the federal 45L tax credit for energy efficient homes.
