HECS delivers Blower Door & Duct Leakage Testing across Tazewell County and east of Peoria along I-74. HECS is an NCI-certified, Louisville-Kentucky-headquartered testing firm serving Illinois since 2009. County-specific service includes a free scoping call, a fixed-fee 24-hour proposal, and a certified report that passes program review in the first round.
Local code officials, builders, developers, and program administrators across Illinois trust HECS for third-party Blower Door Testing because we deliver:
HECS quotes Blower Door Testing projects on a fixed-fee basis after a free scoping call. Cost depends on building size, project complexity, and program requirements. Most Tazewell County projects fall within our standard Midwest service rate. Call (859) 983-7382 or email hecs@hecsusa.com for a project-specific quote within 24 hours.
HECS serves the Peoria metro from our Louisville KY headquarters; most projects are a 5-hour drive. Travel cost is quoted up front in the proposal and bundled with related projects when possible.
HECS field technicians hold RESNET Certified HERS Rater credentials (valid through December 2026). HECS is also an IBHS FORTIFIED Home Evaluator, RESNET Certified HERS Rater, ENERGY STAR Multifamily Reviewer, NGBS Green Certified Verifier, and EarthCraft Certified Verifier. Every HECS report is signed by a credentialed technician — never outsourced, never subcontracted for the signature.
Yes. HECS regularly coordinates Blower Door Testing with local code officials, commissioning authorities (CxA), and HERS raters across Illinois. We deliver reports in the format your reviewer requires and attend coordination meetings when requested. References from Tazewell County-area code officials and developers are available on request.
Most Blower Door Testing engagements in the Tazewell County metro schedule within 2-4 weeks of contract signing. Pre-construction document reviews and pre-drywall inspections are typically scheduled first; final / performance-test visits follow the contractor close-out schedule. Call (859) 983-7382 with your project timeline and we will confirm availability within 24 hours.
If a measured value is outside the prescribed tolerance (e.g., ACH50 over the ENERGY STAR 3 ACH target, or duct leakage to outside above RESNET 380 thresholds), HECS documents the failure with photos and identify-codes for the offending building assemblies. We then work with your GC to schedule a targeted re-test of the failed assemblies after sealing. Re-tests are quoted at a fixed fee per visit (most projects pass after one targeted re-seal). Call (859) 983-7382 to discuss a specific failure-mode case.
Call (859) 983-7382 or email hecs@hecsusa.com with your project type, building size, and inspection schedule. Most scoping calls take under an hour. Within 24 hours you receive a fixed-fee proposal — not an estimate — with deliverables, schedule, and the credentials of the tech who will sign your report.
Most blower door tests in the Tazewell County metro schedule within 1-2 weeks of contract signing. Single-site visits can typically be scheduled in 3-5 business days. Pre-drywall visits are typically scheduled first; final / performance visits follow the contractor close-out schedule. Call (859) 983-7382 with your timeline and we confirm availability within 24 hours.
Yes. HECS carries general liability, professional liability (errors and omissions), and workers compensation coverage at limits that satisfy every Illinois multifamily and commercial GC contract requirement. We file a Certificate of Insurance (COI) within 1-2 business days after engagement letter. Bonded at the state level where required.
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 Illinois 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. Our reports follow the format your reviewers require and we attend coordination meetings when asked. References from Illinois-area code officials and CxA firms are available on request.
