HVAC testing and balancing measures specific system performance (airflows, hydronic flows, temperatures, pressures) per AABC / NEBB / NCI standards. A pressure test is a pass/fail leak test on duct or piping envelope. Most Knoxville projects need TAB + a separate duct leakage test for ENERGY STAR or code compliance.
HECS verifies the service against the applicable Tennessee state energy code, ASHRAE standards, and any program-specific certification path your project requires. Our field verification, certified report, and submission package follow the specific code path your jurisdiction enforces.
If a measured value is outside the prescribed tolerance (airflow ±10% of design, hydronic ±5%, NC noise level per ASHRAE 62.1), HECS documents the specific deviation, recommends the corrective adjustment, and re-tests those points at no charge for the first re-visit. The certification report only ships once all critical measurements pass.
Yes. We coordinate TAB scheduling and access with the CxA of record, the general contractor, the HVAC subcontractor, and the code official as needed. References from Knoxville-area CxAs and GCs available on request.
