Air Systems
Ensuring Superior Indoor Air Quality & Performance
Specialized in air system testing, balancing, and optimization to ensure your HVAC systems operate at peak efficiency. Proper airflow distribution, air quality, and pressure balance are crucial for a comfortable and safe indoor environment. Our expert team conducts thorough testing, calibration, and adjustments to meet industry standards and improve overall system performance.
Testing & Balancing
Fans
Imbalanced or malfunctioning fans can lead to poor ventilation, noise issues, and reduced system efficiency. Our experts conduct fan testing and balancing to restore optimal performance.
- Fan speed and vibration testing
- Airflow measurement and correction
- Ensuring proper static pressure and efficiency
Calibration with BMS
Variable Air Volume (VAV)
VAV systems optimize airflow based on demand, but incorrect calibration can lead to inefficiencies. We calibrate VAV units to integrate seamlessly with your Building Management System (BMS) for precise control.
- Air volume and pressure calibration
- Integration with BMS for real-time monitoring
- Energy-efficient operation and comfort control
Testing & Balancing
DX System
Direct expansion (DX) systems require precise tuning to ensure proper cooling performance. We provide testing, refrigerant level checks, and airflow balancing to maximize efficiency.
- Verification of cooling capacity and airflow
- Checking refrigerant levels and pressure
- Ensuring optimal temperature regulation

Sound Level Analysis & Temperature Measurements
Unwanted noise from HVAC systems can be disruptive. Our sound level analysis helps identify and mitigate excessive noise while temperature measurements ensure consistent indoor climate control.
- Measurement of HVAC system noise levels
- Temperature distribution assessment
- Solutions for noise reduction and comfort enhancement
Testing & Balancing
Room & Building Pressure
Maintaining correct air pressure inside a room or building is essential for ventilation efficiency and occupant safety. Our pressure testing and balancing ensures that air movement is controlled and regulated effectively.
- Positive/negative pressure balance adjustments
- Preventing air infiltration or exfiltration issues
- Optimizing HVAC system for energy efficiency
Gratis International delivers expert MEP testing, balancing, and commissioning services—ensuring building systems run safely, efficiently, and as designed.
