HVAC Testing Adjusting and Balancing (TAB) Services

HVAC Testing, Adjusting & Balancing (TAB)

HVAC Testing, Adjusting & Balancing (TAB) is a critical process that verifies whether heating, ventilation, and air-conditioning systems are performing as per design intent. At Aerosys HVAC, we deliver NEBB-certified HVAC TAB services that align HVAC systems with globally accepted performance standards for accuracy, safety, and energy efficiency.

Our TAB services focus on validating real-world HVAC performance, not assumptions. By combining calibrated instrumentation, proven testing methodologies, and certified expertise, we ensure HVAC systems deliver consistent comfort, reliable indoor air quality, and long-term operational efficiency.

What TAB Really Means for Your HVAC System?

HVAC Testing, Adjusting, and Balancing is the systematic process of measuring and regulating airflow and hydronic flow within HVAC systems. The objective is to confirm that air and water distribution across equipment and occupied spaces matches approved design specifications.

In HVAC installations, even minor imbalances in airflow or water flow can result in uneven temperatures, ventilation deficiencies, excessive energy consumption, and reduced equipment life. TAB addresses these issues by fine-tuning system performance and restoring balance across all components.

Why TAB Isn’t Optional Anymore?

Effective HVAC TAB requires precise instrumentation, standardized procedures, and certified professionals. As a NEBB-certified TAB company, Aerosys applies industry-recognized testing protocols to verify HVAC system performance against measurable benchmarks.

TAB confirms that HVAC systems operate safely, efficiently, and at their rated capacity. It also provides documented evidence of compliance, which is essential for commissioning, audits, regulatory approvals, and long-term facility management.

What We Test, Adjust, and Validate?

HVAC TAB services encompass comprehensive testing, measurement, and performance validation across air-side and water-side systems. This includes measuring airflow rates across air handling units and terminal devices, verifying hydronic flow rates in chilled water and hot water systems, and evaluating heat transfer performance of coils and exchangers.

TAB also involves balancing ventilation systems to eliminate hot and cold pockets, correcting temperature inconsistencies across zones, and validating pressure relationships where required. All testing activities are performed using calibrated instruments and documented through detailed TAB reports.

Where TAB Has the Highest Impact?

HVAC TAB is especially critical for facilities with complex mechanical systems, including commercial buildings, industrial plants, pharmaceutical cleanrooms, healthcare facilities, and data centers.

In these environments, HVAC performance directly impacts occupant comfort, indoor air quality, regulatory compliance, and operational continuity. TAB ensures HVAC systems perform reliably under varying load conditions while meeting applicable codes, standards, and project requirements.

Operational and Energy Efficiency Benefits

A properly balanced HVAC system delivers measurable operational benefits. HVAC TAB improves indoor air quality by ensuring correct ventilation rates and airflow distribution. It enhances thermal comfort by maintaining consistent temperatures across occupied areas.

From an energy perspective, optimized airflow and hydronic balance reduce unnecessary fan and pump energy, leading to lower operating expenses and improved system reliability. Over time, TAB contributes to extended equipment life and reduced maintenance costs.

Value of HVAC TAB Data and Reporting

The data generated through HVAC TAB provides valuable insights for mechanical engineers, facility managers, and property owners. A comprehensive TAB report highlights system performance, identifies deficiencies, and outlines opportunities for optimization.

TAB reports also establish a reliable performance baseline that supports future system upgrades, energy efficiency initiatives, and HVAC commissioning activities. This data-driven approach minimizes guesswork and supports informed decision-making.

Benefits of HVAC TAB for New and Existing Facilities

For new facilities, HVAC TAB ensures systems are balanced as per approved design intent prior to handover. It confirms equipment operates at rated capacity and identifies installation or design issues early, reducing post-occupancy corrections.

For existing facilities, HVAC TAB establishes actual airflow and water flow distribution and compares current performance against original design intent. This helps identify issues affecting comfort, energy efficiency, or process reliability and enables targeted improvements without unnecessary capital expenditure.
