Air Balancing
Supply, return, exhaust, and relief air balancing to AABC procedures, with a focus on critical healthcare environments.
- OR, ICU, NICU & diagnostic spaces
- Isolation room pressurization & ACH verification
- VAV, CAV, and induction systems
Keeping critical healthcare spaces safe and compliant.
Independent testing and balancing for hospitals, pharmacies and laboratories across Ontario and the Greater Toronto Area.

Testing, Adjusting & Balancing Services
Comprehensive TAB and commissioning support for healthcare, pharmaceutical, laboratory, and complex commercial projects across Ontario and the GTA.
Hydronic Balancing
Precise balancing for chilled water, hot water, glycol, and condenser water systems to optimize ∆T and system performance.
- Primary/secondary and decoupled systems
- Pump curves, flows, and energy optimization
- OR and critical reheat coil verification
Duct Leakage & Investigative TAB
SMACNA duct leakage testing and investigative TAB for persistent pressure, comfort, or IAQ issues in critical areas.
- SMACNA CL 3 / 6 / 12 duct leakage testing
- OR cores, exhaust risers, specialty systems
- Diagnostic TAB for existing healthcare facilities
Specializing in Healthcare & Pharmaceutical Facilities
Healthcare ventilation is not standard TAB. AWPB has balanced over 25 million square feet of Canadian hospitals, clinics, and pharmaceutical facilities where minor airflow or pressurization errors can create real risk for patients, staff, and product integrity.
Critical Environments
- Operating Rooms & Procedure Suites
- ICU / NICU & critical care units
- Airborne isolation & protective environments
- Endoscopy & bronchoscopy areas
Labs & Pharma
- GMP clean rooms & support spaces
- Hospital & oncology pharmacies
- USP 797 / 800 compounding rooms
- Biosafety cabinets & fume hoods
Our field procedures align with CSA Z317.2 and current infection prevention & control (IPAC) guidance. Data is recorded in a way that engineers, facility teams, and accreditation bodies can read quickly: clear room-by-room results, pressure and airflow summaries, and targeted deficiency lists tied to specific rooms and systems
Typical Healthcare TAB Scope
- Review design documents and sequences for critical spaces.
- Balance associated AHUs, VAVs, terminals, and hydronic systems.
- Verify room pressurization and ACH for OR/AIIR/PE rooms.
- Coordinate with controls/BAS teams.
- Issue deficiencies and performance observations.
Need to resolve a persistent pressure or IAQ problem? AWPB also provides investigative TAB for existing healthcare facilities.
What Design Teams Can Expect
During Testing and Balancing
We provide clear, field-based feedback during testing so design teams understand how systems are performing under real operating conditions. Our role is to verify airflow (or hydronic flow), pressures, HVAC equipment performance as well as room performance against the intended targets and communicate any constraints that affect achievable results.
- Transparent reporting of measured values and tolerances
- Identification of field conditions affecting target flows and/or pressures
- Clear documentation to support post-TAB decisions
- Coordination with mechanical and controls teams during testing
