Before releasing refrigerant, we pressurize the system with dry nitrogen to detect even microscopic leaks. The system is monitored under stable pressure to ensure complete sealing. This prevents future gas loss and guarantees long-term reliability inside walls and ceilings.

After pressure testing, we evacuate the system using a professional vacuum pump and micron gauge to below 500 microns. This removes air and moisture from the pipes. Proper evacuation prevents acid formation, protects the compressor, and ensures maximum cooling efficiency.

Each copper refrigerant line is insulated individually. Separate insulation prevents condensation, reduces thermal loss, and improves system efficiency. This also protects walls and ceilings from moisture damage over time.

Flare connections are tightened using a calibrated torque wrench according to manufacturer specifications. Correct torque prevents both under-tightening (which causes leaks) and over-tightening (which damages fittings). This ensures secure and durable refrigerant connections.
