Our experienced refrigerant specialists are equipped to handle all types of gas top-up and refrigerant services:
Our service begins with a thorough air conditioning performance assessment. We test cooling output and temperature, measure refrigerant pressure and levels, inspect for visible leaks or damage, evaluate system efficiency, check electrical components and controls, and assess overall system condition. This detailed assessment determines whether you need a simple gas top-up, leak repair, or more extensive refrigeration work to restore proper cooling.
Restore cooling performance with professional refrigerant gas top-ups. We evacuate remaining refrigerant safely, pressure test the system for leaks, recharge with correct refrigerant type and quantity, verify proper pressure and performance, test cooling efficiency and temperature, and ensure your air conditioning operates at optimal capacity with the right refrigerant charge for maximum efficiency and cooling power.
Stop refrigerant loss with professional leak detection and repair services. We use electronic leak detectors to locate leaks, apply UV dye for difficult leak identification, pressure test systems to confirm leaks, repair pipe joints and connections, replace damaged coils or components, and fix refrigerant leaks properly before recharging to prevent ongoing gas loss and performance degradation.
Update outdated systems with refrigerant conversion services. We convert R22 systems to modern alternatives, upgrade to environmentally friendly refrigerants, retrofit systems for R32 or R410A, replace incompatible components where needed, ensure system compatibility with new refrigerants, and help you transition from phased-out refrigerants to approved modern alternatives.
Keep commercial cooling systems operating efficiently with professional refrigerant services. We service commercial air conditioning systems, maintain chillers and cooling towers, top up cold room and freezer refrigerant, service retail refrigeration equipment, provide scheduled refrigerant maintenance, and deliver commercial-grade refrigerant services that minimize downtime and maintain proper temperatures for business operations.
Ensure environmental compliance with proper refrigerant handling and recovery. We recover refrigerants during repairs and servicing, dispose of old refrigerants legally, maintain refrigerant handling records, comply with Australian refrigerant regulations, use certified recovery equipment, and follow environmental best practices for all refrigerant work protecting the environment and ensuring legal compliance.
Ensure leak-free operation with professional pressure testing and commissioning. We vacuum test systems before charging, pressure test for leaks and integrity, verify proper refrigerant flow, commission new installations correctly, test all safety controls and switches, and ensure refrigeration systems operate safely and efficiently with correct pressures and temperatures throughout.
Maintain optimal cooling performance with scheduled refrigerant maintenance. We provide annual gas level checks, regular leak inspections, pressure testing services, performance monitoring, preventative maintenance programs, and scheduled refrigerant servicing that prevents performance loss, extends system life, and ensures reliable cooling throughout Darwin's hot climate.
