Execution Process

1. Equipment Procurement & Delivery: Direct OEM dispatch to site with factory quality certificates and inspection.
2. Sleeve, Support & Piping Installation: Rigging heavy outdoor units and laying insulated copper loops with anti-vibration isolation.
3. Indoor Unit & Duct Fixing: Positioning AHUs/FCUs with laser-level alignment and acoustic sound attenuators.
4. Pressure & Vacuum Dehydration: Triple evacuation down to 500 microns followed by precise electronic refrigerant charging.

Frequently Asked Questions

What brands of HVAC & Chiller systems do you supply and install?

We work directly with leading tier-1 brands including Daikin, Blue Star, Mitsubishi Electric, O General, Voltas, Carrier, Midea, Samsung, Zeco, and Hitachi, offering full manufacturer warranty coverage.

How do you prevent refrigerant leaks over long runs?

We strictly enforce nitrogen-purged brazing to prevent internal copper oxide scaling, followed by a 500 PSI nitrogen holding test over 48 hours before vacuum dehydration.
