GreenTech Air Balancing is an independent HVAC Testing, Adjusting & Balancing (TAB) firm based in Kanata, Ottawa. We measure, adjust and document airflow and water flow in commercial, institutional and industrial buildings across the city — Kanata, Nepean, Barrhaven, Stittsville, Orléans, Gloucester, Vanier, the Glebe, Westboro and downtown — and in Eastern Ontario (Arnprior, Renfrew, Pembroke, Cornwall, Kingston, Brockville). Because we do not sell or install equipment, our reports are impartial, and they are written the way Ottawa consulting engineers and general contractors expect: measured vs design, percentage of design for every terminal, fan and pump, deficiencies and limitations.
Ottawa projects we have balanced include an Amazon distribution centre, the Rideau Centre, Carleton University, the University of Ottawa, La Cité College, a Walmart Supercentre and Ottawa International Airport terminal facilities. We work for mechanical and general contractors on new construction and tenant fit-outs (Division 23 05 93), for consulting engineers who need a third-party TAB report, for dental and medical clinics preparing an OHP inspection, for restaurants with kitchen hood and make-up air problems, and for property managers with comfort complaints in existing buildings.

We begin with a detailed review of the HVAC systems to understand design intent, current operating conditions, and performance gaps. Our team evaluates airflow, waterflow, static pressure, and control sequences to establish an accurate baseline before any adjustments are made.
Using industry-standard TAB instruments, we perform precise field measurements across the entire system — diffusers, grilles, VAV boxes, terminal units, hydronic loops, and mechanical equipment. Each measurement follows recognized balancing procedures to ensure repeatable and reliable results.
Once optimal performance is achieved, we compile a comprehensive report including measured data, compliance verification, system observations, and corrective recommendations. Our documentation is structured for engineers, consultants, and facility managers to support long-term building efficiency.
