Blower Door Testing in Chicago, IL | HECS

Blower Door & Duct Leakage Testing in Chicago, IL is delivered by HECS — an NCI-certified, Kentucky-based testing firm serving Illinois and the broader Midwest since 2009.

Chicago is a 5-hour drive from our Louisville office; for Chicago projects we typically partner with a local field tech to minimize travel cost.

Why Chicago property owners choose HECS for blower door

Local code officials, builders, developers, and program administrators across Illinois trust HECS for third-party blower door because we deliver:

• NCI-certified field technicians — every HECS tech holds current NCI Certified Commercial Air Balancer credentials. The person who takes the readings is the person who signs your report.
• Fixed-fee proposals in 24 hours — not estimates, not time-and-materials. We quote travel cost up front, so the invoice matches the proposal.
• Reports that pass program review — ENERGY STAR, NGBS Green, EarthCraft, 45L IRS Form 8908, FORTIFIED IBHS submission, code-official review. We deliver in the format your reviewer needs.
• Local code expertise — Chicago projects typically reference the 2019 Chicago Building Code (one of the most stringent in the nation) with 2018 IECC for energy. IHDA (Illinois Housing Development Authority) requires NGBS Green, ENERGY STAR, or LEED for LIHTC-funded multifamily.
• One project manager for the whole job — TAB, blower door, energy cert, FORTIFIED: we coordinate scheduling so you make one phone call, not five.
