Our experienced air conditioning specialists are equipped to handle all types of multi-split system installations, repairs, and maintenance:
Planning to climate control multiple rooms efficiently? We assess your home layout, room sizes, and usage patterns to design the perfect multi-split configuration. We recommend the ideal combination of indoor units (wall-mounted, ceiling cassette, or floor console) connected to a single outdoor unit, ensuring optimal performance and energy efficiency.
When one or more zones in your multi-split system stop working, we quickly diagnose and repair the issue. Common problems include refrigerant leaks, faulty indoor unit controls, communication errors between units, compressor issues, and airflow problems. We repair individual indoor unit failures, outdoor unit problems, refrigerant leaks, and electrical faults.
Regular maintenance extends the lifespan of your multi-split system and prevents costly breakdowns. With multiple indoor units sharing one outdoor compressor, proper servicing is essential to maintain efficiency across all zones. Our comprehensive maintenance service includes cleaning all indoor unit filters, inspecting outdoor unit coils, checking refrigerant levels, and testing individual zone controls.
Need to add another room to your existing multi-split system? We can assess whether your current outdoor unit has capacity for additional indoor units, or recommend upgrading to a larger system to accommodate more zones. We handle adding new indoor units, upgrading to higher efficiency models, and installing Wi-Fi smart controls.
Multi-split systems are inherently efficient, but improper setup can increase running costs. We conduct detailed energy audits to optimise your system's performance across all zones - including zone-by-zone measurements, thermostat review, insulation assessment, and usage pattern analysis.
Perfect for offices, retail spaces, restaurants, and medical facilities, commercial multi-split systems offer flexible climate control without major renovations. We design and install systems tailored to your business needs, with options for after-hours operation scheduling and individual zone control.
When your multi-split system fails during extreme weather, multiple rooms lose climate control at once. We offer same-day emergency repairs across all region, with technicians available 7 days a week including public holidays—with rapid response, fully stocked service vehicles, and upfront pricing.
