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%, it will not qualify.
• Qualifying Efficiency Requirement: Leakage reduction must be quantifiable, aiming for a leakage reduction to 8% 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.
