Discuss This ServiceWhy this service matters
Define the requirement before arriving in the field.
Testing, adjusting and balancing is the field process used to verify how an HVAC system actually performs compared with its design intent. It is not simply a final set of airflow readings. Effective TAB evaluates equipment operation, distribution-system performance, balancing-device positions, control response and the relationships between connected spaces.
Micron combines methodical measurement with practical mechanical-system knowledge. That broader view helps contractors, engineers and owners identify whether a deficiency originates at the equipment, duct or piping system, terminal device, controls sequence or room boundary.
Service planning
A defined scope and a prepared facility.
Final methods and acceptance criteria depend on your facility, equipment, operating state and applicable requirements.
What the scope may include
Supply and return airflow
Exhaust relationships
Room pressure investigation
Verification and findings
Preparing for the visit
Room and system layouts
Access and operating state
Design performance criteria
Controls readiness
Performance considerations
Conditions that shape the result.
Understanding the surrounding system helps prevent a test result from being interpreted without the context needed to correct it.
Renovation or system change
Re-establish air and water distribution after equipment, controls or space-use modifications.
Comfort or pressure complaints
Investigate hot and cold zones, inadequate airflow, exhaust imbalance or unstable room relationships.
Clear documentation
Results your team can use.
Before the visit, we align the report contents with the people who will review it. This reduces ambiguity about tested conditions, acceptance criteria, deficiencies and retest status.
Equipment and terminal-device measurements compared with design values
Documented final settings and balancing-device positions by scope
Deficiency log with field observations and items requiring other trades
NEBB report format when specified and included in the contracted scope
Frequently asked questions
Plan the visit with fewer surprises.
View the complete Test & Balance capabilityWhen is an HVAC system ready for TAB?
Equipment should be installed and started, filters clean, controls functional, dampers accessible, ceilings substantially complete and systems operating in the intended mode. Early readiness review prevents avoidable remobilization.
Can TAB correct every airflow problem?
No. Balancing devices can redistribute available capacity, but TAB cannot create missing fan capacity, repair major duct restrictions, correct incomplete controls sequences or replace deficient design. Those conditions should be identified and assigned for correction.
What is the difference between air balancing and hydronic balancing?
Air balancing measures and adjusts supply, return, outside and exhaust air. Hydronic balancing measures and adjusts water flow through pumps, coils and distribution circuits. Many systems require both disciplines to reach intended performance.
