Optimizing HVAC Performance and Indoor Environmental Quality

An improperly balanced HVAC system leads to excessive energy consumption, uneven thermal comfort, pressure differential drift, and potential regulatory non-compliance. Our certified TAB technicians use advanced, NIST-traceable instrumentation to execute precise measurements, adjustments, and documentation across all commercial, industrial, and critical life science air and hydronic systems. Whether you are commissioning a newly installed mechanical plant or executing complex retrofits, our team brings deep technical capabilities to align your infrastructure perfectly with engineering specifications.

Our Pressure Calibration Process

A Rigorous Step-by-Step Metrology Protocol

  1. Phase 1

    Plan Review & Data Gathering

    Analyzing mechanical engineering drawings, equipment submittals, and design specifications to map out the facility’s air and water loops.

  2. Phase 2

    Initial System Survey & Readiness Check

    Inspecting the mechanical installation to ensure filters are clean, belts are tensioned, and systems are fully operational prior to testing.

  3. Phase 3

    Field Testing, Adjusting & Balancing

    Executing systematic adjustments on air handlers, pumps, fans, and terminal units to bring all systems into strict design tolerance.

  4. Phase 4

    Certified Engineering Report Handover

    Delivering a comprehensive, audit-ready TAB report complete with final flow data, equipment nameplate details, and instrument calibration records.

Frequently Ask Questions

  • What standards do you follow for TAB services?

    Our testing and balancing procedures comply with industry standards set by NEBB, AABC, and ASHRAE.

  • Why is professional system balancing important?

    ? Proper TAB ensures energy efficiency, extends equipment life, maintains required room pressure relationships, and resolves occupant thermal comfort issues.

  • When should HVAC systems be balanced?

    TAB is essential during initial facility commissioning, after major HVAC retrofits or renovations, or when changing building layouts that impact thermal loads.

  • What documentation is provided upon completion?

    You receive a detailed certified balancing report containing all air and water flow measurements, final equipment settings, and instrument traceability data.
