Certified Testing, Adjusting, and Balancing

We are NEBB (National Environmental Balancing Bureau) certified for air and water balance.

Testing, adjusting and balancing is an essential part of any heating, ventilating, and air conditioning (HVAC) installation. All facilities require correct flow of air and water to provide optimum operating conditions, comfort levels, and energy efficiencies from building systems.

Benefits Include:

  • Lower your operating costs by reducing energy usage
  • Increase your staff's productivity by improving their comfort level
  • Prolong the life of your equipment
  • Verify room pressurization or air changes for health and safety requirements
  • Assisting design engineers in determining available capacities for future renovations or building additions
  • Maintain a "healthy building"
  • Optimizing performance of mechanical systems
  • Troubleshooting system performance and problems with all types of HVAC systems
  • Providing long-term solutions to HVAC problems, not short term fixes
  • Verifying proper operation of building controls
  • Adjusting systems to maintain minimal temperature variances throughout spaces for overall comfort
  • Rebalancing of existing systems that are no longer operating properly after years of modifications, upgrades and other changes that have been made.


Frequently, building systems fail to perform to the satisfaction of the building owner and occupants.

What doesn't go right:

  • Building management control systems may not meet the needs of the office and management staff.
  • Electrical systems may not deliver dependable power supply at varying load requirements.
  • HVAC systems may not maintain the desired temperatures and ventilation rates in building spaces.
  • Life safety systems may generate frequent "false alarms."
  • Hydronic systems may not provide hot and cold water supply at desired temperature and pressure.
