A blower door test measures whole-building air leakage through the building envelope (ACH50, CFM50 per ASTM E779). A duct leakage test measures air leakage from the HVAC duct system to outside, performed with a DuctBlaster or Pressure Pan per RESNET Standard 380. ENERGY STAR, NGBS, and most code-official pathways require both. HECS performs both at the same site visit on the same day.
HECS verifies the service against the applicable Ohio state energy code, ASHRAE standards, and program-specific certification requirements. Our field verification, certified report, and submission package follow the specific code path your project is required to meet (IRC, IECC, IECC Stretch Code, ENERGY STAR v3.0 or v3.1, NGBS 2015 or 2020, EarthCraft, RESNET). We also flag any local amendments and review them with your code official before submission.
If a measured ACH50 or CFM50 exceeds the prescribed limit (ENERGY STAR 3 ≤ 3 ACH50 for LIHTC, NGBS Green ≤ 5 ACH50, code-official typically ≤ 5 ACH50), HECS documents the failure with photos and identifies the highest-leakage assemblies. We then work with your GC to schedule a targeted re-test of sealed assemblies. Re-tests are quoted at a fixed fee per visit; most projects pass after one targeted re-seal of penetrations, attic access points, and garage-to-house boundaries.
Yes. We coordinate blower door scheduling and access with the CxA of record, the general contractor, the insulation contractor, the air-sealing subcontractor, and any local code officials.
