Professional Air Balance: HVAC performance based solutions and design

Mission critical · Infrastructure · Consultative

Facilities that perform exactly as designed.

We assess, commission, balance and run the mechanical systems behind military bases, hospitals, schools and data centers, so the infrastructure you depend on does what it was built to do.

Why PAB

No fancy presentations. Real answers.

PAB was founded out of frustration with the service large testing and balancing firms deliver. We send seasoned people who have run mission-critical operations, and we tell you plainly what we find.

Case study · International School of Beijing

Clean indoor air, whatever the outdoor reading.

Thirty-five new fresh-air handlers with HEPA filtration and positive building pressurization cut indoor fine-particle levels from 17 to 3 µg/m³, holding steady even when outdoor readings topped 270.
