Services
Air Balancing
Our air balancing service measures and adjusts cubic feet per minute (CFM) airflow rates at HVAC system inlets and outlets. This ensures temperature uniformity, proper ventilation, and energy efficiency while meeting ASHRAE standards. We identify and correct pressure imbalances that affect occupant comfort and system performance.
Hydronic Balancing
We measure and optimize gallons per minute (GPM) water flow rates in hydronic systems to ensure proper heat transfer. This service improves occupant comfort by maintaining consistent space temperatures and reduces energy consumption through optimized pump operation and temperature splits.
Duct Leak Testing
Our duct leakage testing quantifies air loss at specified internal pressures using SMACNA protocols. We identify leaks that cause energy waste, comfort issues, and pressurization problems while ensuring compliance with LEED and energy code requirements.
Sound Testing
We conduct baseline and operational sound measurements to identify HVAC noise sources. This service ensures compliance with sound pressure level requirements and prevents long-term occupant health risks from excessive noise exposure in commercial environments.
Design Reviews
Our pre-engineering surveys provide data-driven insights for HVAC system design. We analyze existing system performance, create detailed flow measurements, and produce coil performance reports to support informed design decisions during renovation projects.
