Required Documentation:
• Leakage Testing Reports: Documentation, including pre- and post-duct leakage testing results, demonstrating the effectiveness of the duct sealing in reducing leakage.
• Air Balance Report: A copy of the air balance report showing the percentage or CFM of leakage at operating pressure before and after the duct sealing project.
• Professional Verification: An invoice or certification from a commercial HVAC professional confirming the completion of the duct sealing work.
• The capacity of the HVAC unit(s).
Important Consideration:
• Large commercial, light industrial and heavy industrial buildings should consider applying through the custom project section.
- Applicability: Eligible for retrofit/repair in small commercial buildings.
- Baseline Efficiency: The baseline leakage level is listed in the table. If a percentage falls between the two proposed ones, it will be considered as the lower percentage. If a percentage is less than 15 percent, it will not qualify.
- Qualifying Efficiency Requirement: Leakage reduction must be quantifiable, aiming for a leakage reduction to 8 percent by considering both supply and return ducts, where the reduction is measured as the decrease in CFM (at operating static pressure) relative to the total CFM before sealing.
- Exclusions:
- Redundant or backup HVAC units.
- New construction projects.
- Other requirements: Only air leakage to unconditioned spaces qualifies for this incentive.
