This week in Texas, our founder Siwei Chen from Greentech Engineering Heating & Air Conditioning successfully completed the NCI Air Balancing Training in Texas — a nationally recognized certification program by the National Comfort Institute (NCI). This advanced training equips HVAC professionals to measure, balance, and verify airflow for maximum comfort, efficiency, and indoor air quality in real homes.
At Greentech, we believe that great HVAC performance starts with precise system design and verified airflow. The NCI Air Balancing Training helps contractors identify restrictions, improve duct performance, and deliver balanced comfort for every room. By applying these high-performance HVAC principles across the Dallas–Fort Worth (DFW) area, our team continues to raise the standard for reliability and energy savings.
💡 Why NCI Air Balancing Training in Texas Matters for DFW Homeowners
Most homeowners never realize that poor airflow can lead to uneven heating, high energy bills, and premature equipment wear. Through the NCI Air Balancing Training in Texas, our certified team learns to pinpoint these airflow issues and correct them using proven field measurements — not guesswork. This ensures every Greentech installation meets both ACCA and Daikin Comfort Pro performance standards.
🧠 What Is NCI and Why It Matters
—Why NCI Air Balancing Training Matters for Texas HVAC Contractors
Founded in 1992, the National Comfort Institute (NCI) is widely recognized as the leader in HVAC performance-based training, certification, and standards.
Rather than focusing only on equipment brands or replacement, NCI teaches contractors how to measure, verify, and optimize system performance through proper airflow, static pressure testing, and duct balancing.
For HVAC professionals like Greentech, this training bridges the gap between traditional installation and truly engineered comfort systems — where science, testing, and data ensure your home performs exactly as designed.

💡 What Siwei Chen Learned from NCI’s Residential Air Balancing Program
During the 3-day course, participants worked hands-on with live HVAC systems and diagnostic instruments. The training covered:
✅ Airflow Measurement Techniques – Using flow hoods, manometers, and static pressure testing to verify performance.
✅ System Balancing – Adjusting dampers, ducts, and registers so each room receives the right airflow and temperature.
✅ Duct Design Diagnostics – Identifying undersized, leaky, or restrictive ducts that limit system efficiency.
✅ Fan and Blower Performance Analysis – Ensuring the blower delivers designed airflow according to ACCA Manual D standards.
✅ High-Performance Verification – Measuring Total External Static Pressure (TESP) to document actual results.
This training ensures that every Greentech installation — from new HVAC replacements to complete duct redesigns — follows measurable, performance-based standards rather than guesswork.
🌬 Why Air Balancing Matters for Homeowners
## Why NCI Air Balancing Training in Texas Matters for HVAC Professionals
Most homeowners notice the signs of unbalanced airflow without realizing the cause:
-
One room feels hot while another stays cold
-
Airflow seems weak in upstairs rooms
-
The AC or furnace runs longer than expected
-
Energy bills rise even though comfort doesn’t improve
These issues are often the result of poor duct design or improper airflow calibration.
That’s why air balancing — the process of measuring and adjusting airflow throughout the duct system — is so important.
When done correctly, homeowners can expect:
✅ Consistent room temperatures
✅ Quieter system operation
✅ Better indoor air quality
✅ Improved energy efficiency
✅ Longer equipment lifespan
Through NCI-certified methods, Greentech Engineering Heating & Air Conditioning ensures your comfort system performs to its full potential — verified by data, not just appearance.This Texas-based training ensures every Greentech Engineering HVAC system delivers balanced airflow.
