VRV / VRF Maintenance KL & Selangor — Daikin · Mitsubishi · Toshiba
A VRV system in a KL Grade-A office runs 14 hours a day, 6-7 days a week, in tropical humidity. Manufacturer recommended maintenance interval is quarterly. Skip a service cycle and you accelerate compressor wear, drift refrigerant balance across the multi-zone loop, and risk a partial-shutdown failure that takes a floor offline for 48-72 hours. We run quarterly AMC schedules calibrated to your system runtime profile and refrigerant type.
