Frequently Asked Questions

What exactly is it that you do?

Our certified and trained technicians use specialized air and hydronic flow measuring equipment on-site to test your building’s mechanical equipment. Using the testing data, our technicians calibrate the control systems to ensure proper air flow throughout the areas served by the system.


Why do systems need re-balancing? Shouldn’t they just operate as designed?

Mechanical systems never operate as designed on paper due to variances in climate, pressure and occupancy or from installation deviations. Occupants/users also tweak small things over time (like individual intake/vent covers) that, in accumulation, impact the overall system performance. As such, every system requires an initial calibration and periodic re-calibration.

Why can’t my in-house facilities team or the contractor who installed my system perform the testing and balancing?

Testing and balancing of large/complex systems is highly technical and time-consuming. It requires specialized training and equipment. Our certified technicians use regularly calibrated testing equipment to ensure accurate and repeatable measurements. Our technicians use that data and their training to rebalance your entire system while on-site. If your mechanical system requires a repair, our independent and non-biased data also helps resolve the issue with third parties.


When should we contact you? Some of the most common reasons are:

  • Before installation of a new system, the retrofitting of an existing system or a repair

  • The rooms in your building feel unbalanced (hot/cold spots, inconsistent air flow, etc.)

  • For annual pressure and/or fume hood testing for hospital Joint Commission certification

  • For annual fume hood testing for Department of Public Health regulation compliance 

  • For annual cleanroom performance testing for ISO certifications

  • To comply with NFPA and insurance requirements for fire damper testing

  • If you would like to evaluate your energy usage for potential energy savings

What information do you need for a price estimate?

We will require your basic contact information, the project timing, scope, and mechanical/planning drawings. You can submit a request through our website or email us directly at
