Air Balancing is the process of testing and fine-tuning your HVAC system to make sure it's actually delivering the comfort and efficiency your building deserves. After installation or major work, systems often run imbalanced—some areas get too much air, others get too little. CalHERS Energy measures, adjusts, and documents everything so your system works as designed. Why You Need Professional Air Balancing If you've recently installed new HVAC equipment, expanded a building section, or your tenants are complaining about hot/cold zones and drafts, it's time to balance. You might also need it if you're seeing unexpectedly high energy bills or preparing for inspection sign-off. What We Measure On Your System We use calibrated instruments to check: • Airflow at every vent, return grille and exhaust point • Fan performance and motor load • Pressure throughout the ductwork • Outside air intake and fresh air levels • Room pressurization where required • Control setpoints and damper positions • Noise levels and airflow patterns Every measurement is tied back to your engineer's design and the building codes so you know exactly where your system stands. How We Balance Your System Step 1 – Planning: We review your building plans and HVAC design to understand what you're trying to achieve. This becomes our target. Step 2 – Initial Testing: We measure how your system is running today so we can see what needs adjustment. Step 3 – Tuning: We adjust dampers, fan speeds and outside air settings to get each room and zone as close to design specifications as practical, while keeping noise and energy use reasonable. Step 4 – Final Testing & Report: We re-measure everything and document the results in a clear report showing your system is balanced and ready. Step 5 – Inspection Support: We're here to answer questions from inspectors or engineers and keep your project on track. We Work Across Every Building Type: Office buildings, schools, hospitals, restaurants, hotels, manufacturing facilities, cannabis operations, and more. If it has ductwork and air handlers, we can balance it.
Our TAB work is performed in alignment with ASHRAE procedures, and we understand how our results tie into California Title 24, plan check requirements, Mechanical Acceptance Testing and commissioning. Where required, we coordinate with your engineer, HERS/ECC rater and commissioning agent so everyone is working off the same verified numbers.
Air balancing measures and adjusts HVAC airflow at every supply and return register to match design specifications within +/-10% tolerance. Certified technicians use calibrated flow hoods and digital tools to ensure uniform temperature distribution and reduce energy consumption by 15-30%.
Air balancing typically requires 1-3 days for most commercial buildings. A 50,000 sq ft office takes approximately 2 days. Complex facilities with multiple air handlers or VAV systems may need 4-5 days.
Air balancing is mandatory for California commercial new construction and HVAC system alterations over 40,000 BTU. Warning signs you need TAB include temperature variations exceeding 3 degrees between zones and utility bills 20%+ above benchmarks.
