Our Process

How It Works

01

System Survey & Baseline

We carry out a full site inspection and baseline performance read — flow/return temperatures, buffer vessel, COP and control settings — then log faults and accessibility issues before any work begins.

02

Detailed Service & Testing

Compressor and inverter checks, refrigerant circuit pressure and leak detection, fan and heat-exchanger clean, electrical supply and isolator checks, defrost cycle review and thermostat/control calibration.

03

Tuning, Report & Recommendations

We optimise flow temperatures, control logic and schedules for seasonal performance, issue a detailed service report with findings and recommend parts or further works to maintain efficiency and compliance.
