If your split system isn’t cooling like it used to, our technicians can quickly diagnose and repair the issue — from gas leaks and regassing to faulty boards, fans, or sensors. We focus on cost-effective, practical repairs that extend your unit’s life without unnecessary upselling. Whether it needs a simple service or a major component replaced, you’ll get honest advice and clear options. If repair makes sense, we’ll fix it right — and if it doesn’t, we’ll recommend the most economical replacement solution.

When it’s time to upgrade your air conditioner, Polar AC provides reliable split-system replacements built to handle Darwin’s heat and humidity. We mainly install Daikin, Fujitsu and Mitsubishi Electric systems, known for efficiency and durability. Our service includes safe removal and full decommissioning of your old unit, recovery of refrigerant in accordance with ARCtick requirements, and a clean, compliant installation of your new system. From selecting the right size unit to final testing and handover, we make sure your new aircon runs perfectly from day one.

Regular aircon cleaning keeps your system efficient and your air healthy. Our deep-clean process removes mould, dust, and bacteria from coils, fans, and filters — restoring strong, clean airflow and improving cooling performance. Using low-pressure washing and antibacterial treatments, we make sure every part of your indoor unit is sanitised without damage. Clean systems run cooler, cost less to operate, and last longer — keeping your home comfortable and fresh all year round.
