This page is the IL hub for Blower Door Testing. From here you can jump to any IL city landing page, our Blower Door & Duct Leakage Testing service detail page, and the underlying code / certification framework we follow across all IL projects.
HECS delivers Blower Door Testing across every metro area in IL, including the cities listed at the top of this page. Most IL projects are completed within 4-8 weeks of engagement letter.
HECS quotes every project on a fixed-fee basis after a free scoping call. Cost depends on building size, project complexity, and program requirements. Travel cost is quoted up front. Call (859) 983-7382 or email [email protected] for a project-specific quote within 24 hours.
Yes. HECS field technicians hold RESNET Certified HERS Rater credentials (valid through December 2026) and operate as an IBHS FORTIFIED Home Evaluator, RESNET Certified HERS Rater, ENERGY STAR Multifamily Reviewer, NGBS Green Certified Verifier, and EarthCraft Certified Verifier. Every report is signed by a credentialed technician — never outsourced.
HECS verifies Blower Door Testing against the IL energy code, IL building code, and any local amendments. For LIHTC-funded multifamily, we coordinate with the state-specific housing finance agency (KHC / IHCDA / OHFA / THDA / IHDA depending on state) on certification requirements. References from IL code officials and CxA firms are available on request.
