What We Do

Precision, certified.
Nine disciplines. One standard.

Every system we touch is tested against its design intent, adjusted with calibrated instrumentation, and documented in a certified report your engineers can build on.

01

HVAC Test & Balance

HVAC Test & Balance

Using precision instrumentation, we test and adjust the air and water moving through your systems until they meet design specifications — cutting maintenance costs, extending equipment life, and driving down energy consumption.

02

Life Safety Testing

Life Safety Testing

Thorough, certified testing of your life safety systems — verifying that detection and notification equipment will protect building occupants when an emergency strikes, with comprehensive inspection reports.

03

Critical Room Certification

Critical Room Certification

Operating rooms and critical care spaces demand annual certification. We verify pressure relationships, air changes per hour, and ventilation performance so your healthcare facility stays compliant and your patients stay protected.

04

HVAC Analysis Reports

HVAC Analysis Reports

When a system underperforms, we find out why. Performance testing pinpoints the root cause, establishes true system capacities, and delivers engineered recommendations to restore efficiency.

05

Commissioning & Retro-Cx

Commissioning & Retro-Commissioning

For new construction and existing buildings alike, we verify that every HVAC subsystem operates the way it was engineered to — protecting your investment and locking in energy performance from day one.

06

Kitchen Hood Certification

Kitchen Hood Certification

Commercial kitchen exhaust systems are tested end-to-end, including capture and containment assessment — keeping your kitchen safe, compliant, and performing at full strength.

07

Duct Leak Testing

Duct Leak Testing

By pressurizing your ductwork, we prove whether it was installed and sealed correctly — verifying energy efficiency compliance and stopping conditioned air from disappearing into your ceiling.

08

Stairwell Pressurization

Hover to explore

Stairwell Pressurization

Required by code in high-rise buildings, pressurized stairwells keep exit routes smoke-free during a fire. We test pressurization performance and door operation so occupants can always get out.

09

Sound Testing

Sound Testing

Mechanical systems should be felt in comfort, not heard in every room. We measure and document sound levels so your spaces meet their acoustic requirements.

The Case for Balance

Unbalanced air is money out the door.

A building that isn't properly balanced overworks its equipment, overspends on energy, and underdelivers on comfort — every single day. Proper testing and balancing pays for itself, then keeps paying.

The potential 20-year cost savings for a properly balanced 100,000 sq ft building:

How We Work

A discipline, not a drive-by.

Plan & Review

We study your mechanical drawings and design intent before a single instrument comes off the truck.

Field Testing

Calibrated instrumentation measures the air and water actually moving through the system — not what the drawings hope is moving.

Balance & Adjust

Every terminal, damper, and valve is adjusted until the system performs to specification.

Certified Report

You receive complete, certified documentation — the record your engineers, inspectors, and owners can rely on.
