Why blower door testing matters in Louisville KY
Louisville sits on the Ohio River and sees high humidity most of the year, which makes building envelope airtightness a health and durability issue, not just an energy issue. Hot, humid summer air leaking through a leaky envelope condenses inside wall cavities, feeding mold and degrading insulation R-value. A blower door test quantifies that leakage so HVAC sizing, moisture management, and insulation strategy are correct. Louisville has 8,000+ ENERGY STAR-certified homes and ~2,000 NGBS-certified projects in Kentucky, and blower door testing is the primary verification for each.
ENERGY STAR v3 + NGBS-2023 + 45L blower door requirements
ENERGY STAR v3.1 (Single-Family New Homes) requires blower door test results ≤ 3 ACH50 in CZ 4A. NGBS-2023 requires ≤ 5 ACH50 for Bronze and ≤ 3 ACH50 for Silver/Gold. Pre-2026 45L (now expired) required ≤ 3 ACH50 with envelope package compliance. HECS issues blower door test reports accepted by every ENERGY STAR HSP, RESNET rating provider, NGBS verifier, and HBA Green Building Council in KY.
HECS blower door test process in Louisville
Schedule via (859) 983-7382. A two-person crew arrives in a calibrated blower door rig (Retrotec Q4 or equivalent), sets up the door fan, runs the multi-point test sequence (1, 2, 3, … 50 Pa target pressure), records the CFM50 results, and produces the RESNET-grade report the same day. We coordinate with your HVAC, insulation, and drywall trades so the test runs at the right build stage.
