Services
Testing Adjusting Balancing (TAB)
We systematically test and optimize HVAC systems to ensure proper airflow and water distribution. Our NEBB-certified technicians use precision instruments to measure performance against design specifications. This process improves energy efficiency, occupant comfort, and system longevity while reducing operational costs.
Building Envelope Testing
Our team conducts comprehensive air leakage assessments to identify energy-wasting gaps in building envelopes. Using advanced diagnostic tools, we help achieve compliance with energy codes and improve indoor climate control. This service reduces heating/cooling costs and prevents moisture-related issues in commercial structures.
Infrared Thermal Imaging
We employ Level 1 thermography to detect hidden building system defects without invasive methods. This non-contact technology identifies electrical faults, insulation gaps, and moisture intrusion points. Our certified technicians provide actionable reports to prevent equipment failures and energy losses.
Healthcare Facility Verification
Specialized testing ensures healthcare HVAC systems maintain proper air changes and room pressurization. We verify compliance with infection control standards through precise airflow pattern analysis. This critical service supports patient safety and regulatory compliance in medical facilities.
Sound & Vibration Analysis
Our engineers measure and diagnose mechanical system noise and vibration issues. This proactive testing identifies equipment malfunctions before they cause major failures. We provide solutions that improve system performance while maintaining occupant comfort in commercial buildings.
