Seventeen services, one standard: measure everything, certify every number, and deliver the report the next day. All work is performed by NEBB certified technicians with calibrated instrumentation.
Our total system balance services ensure HVAC air and hydronic water systems operate at their specified design conditions. We test, adjust, and balance air and water distribution throughout the system to achieve proper flow, pressure, temperature, and equipment performance. Our comprehensive approach helps optimize system operation, comfort, efficiency, and reliability.
Our HVAC system optimization services help improve the performance, efficiency, and reliability of existing mechanical systems. Through detailed testing, analysis, and adjustment of air and water systems, we identify opportunities to correct deficiencies, improve system optimization, and achieve more consistent comfort while reducing unnecessary energy consumption.
Our air and water systems troubleshooting services help identify the root causes of HVAC performance issues. Through detailed testing, measurement, and analysis, we evaluate airflow, waterflow, pressures, temperatures, equipment performance, and system operation to pinpoint deficiencies. We provide practical recommendations to help restore proper system performance, improve comfort, and resolve persistent HVAC issues.
Our pre-construction and existing system survey services help identify potential issues before construction or renovation begins. We review mechanical drawings and specifications while evaluating air and water distribution requirements, equipment access, balancing provisions, and test points. For renovation projects, we can perform pre-demolition surveys to document existing operating conditions, system capacities, and equipment functionality — a valuable baseline for determining the suitability of equipment intended for reuse, while helping identify deficiencies and reduce costly surprises during construction.
Our HVAC test and analysis reports provide a clear, detailed assessment of system performance and operating conditions. We compile field measurements, equipment data, system deficiencies, and performance observations into an easy-to-understand report that helps owners, engineers, and contractors identify issues, make informed decisions, and verify that HVAC systems are operating as intended.
Stairwell pressurization testing verifies that smoke control systems are operating as designed to maintain required pressure within exit stairwells during a fire event. Testing includes measuring stairwell pressure differentials, airflow, and system performance under applicable operating conditions to confirm compliance with project specifications, applicable codes, and life-safety requirements.
Indoor Air Quality (IAQ) testing evaluates environmental conditions within occupied spaces to identify potential air quality concerns and support compliance with applicable building standards and LEED requirements. Testing may include measurement of temperature, humidity, carbon dioxide, particulate matter, and other relevant indoor environmental factors. Results provide objective data to identify potential issues, support corrective actions, and document indoor environmental conditions for building owners, contractors, and project teams.
Smoke control testing verifies the performance of smoke management systems under simulated fire conditions to ensure they operate as designed. Testing may include verification of smoke exhaust, supply air, pressure differentials, airflow, fan operation, dampers, and associated controls. Results help confirm system performance and compliance with applicable codes, project requirements, and life-safety standards.
Fume hood testing verifies that laboratory exhaust systems are operating properly and providing the required containment and protection for laboratory personnel. Testing includes measuring face velocities, airflow, and exhaust performance while verifying proper operation of associated controls and alarms. Results help confirm compliance with project requirements, applicable standards, and laboratory safety guidelines.
Our duct air leakage testing (DALT) services verify the integrity and airtightness of ductwork systems. Using calibrated test equipment, we pressurize duct systems to specified test pressures and measure leakage to confirm compliance with project specifications and industry standards. Testing helps identify deficiencies before systems are concealed and supports proper system performance, energy efficiency, and quality control.
Vibration and sound testing evaluates HVAC equipment and system operation to identify excessive vibration and noise that may impact equipment performance, occupant comfort, or surrounding spaces. Testing can include vibration measurements at equipment and supporting structures, as well as sound level measurements within occupied areas. Results provide objective data to identify potential issues and support corrective measures to achieve acceptable equipment and acoustic performance.
Controls verification evaluates HVAC control sequences and device operation to support accurate testing, adjusting, and balancing. Verification may include reviewing setpoints, confirming equipment and terminal unit responses, checking damper and valve operation, and verifying that systems respond appropriately to control commands. This service helps identify controls-related issues that could affect system performance, airflow, waterflow, and overall building operation.
Commissioning support services provide independent testing and verification of HVAC systems throughout the commissioning process. TAB services support commissioning teams by documenting equipment performance, verifying airflow and waterflow, identifying system deficiencies, and assisting with functional performance testing. This collaborative approach helps ensure HVAC systems operate as designed and meet project requirements, specifications, and owner expectations.
Retro-commissioning evaluates the performance of existing HVAC systems to identify operational deficiencies, control issues, and opportunities for improved efficiency and reliability. Testing and analysis may include equipment performance, airflow and waterflow, system controls, and operating sequences. Findings provide building owners and facility teams with actionable recommendations to improve system performance, occupant comfort, and energy efficiency without requiring major system upgrades.
Third-party testing provides independent verification of HVAC system performance, helping ensure systems meet design requirements, project specifications, and applicable standards. Testing may include independent verification of airflow, waterflow, equipment performance, and system operation, providing owners, contractors, and commissioning teams with objective results and an unbiased assessment of system performance.
Labeled and color-coded schematic drawings provide a clear visual representation of HVAC air and hydronic systems, documenting equipment, ductwork, piping, airflow, and waterflow paths. These drawings can be developed as part of the TAB process to identify system components, clarify distribution paths, and document field conditions and measured performance. They provide owners, contractors, and facility personnel with a valuable reference for system operation, troubleshooting, and future maintenance.
Next-Day TAB Reports provide fast, detailed documentation of testing, adjusting, and balancing results, typically delivered by the next business day following the completion of field testing. Reports clearly document measured conditions, deficiencies, adjustments, and recommendations, allowing contractors, commissioning teams, and owners to quickly review results and address issues without delaying project schedules.
