Hiring a Air Conditioning Technician in Seven Hills

Before hiring any air conditioning technician in Seven Hills, use this checklist to protect yourself and ensure you're working with a properly licensed and insured professional.

1. Verify their ARC Refrigerant Handling Licence — Under Australian law, only technicians holding a current Refrigerant Handling Licence (RHL) issued by the Australian Refrigeration Council can purchase, handle, or dispose of refrigerant gases. Ask for their ARC licence number and verify it on the ARC online register. Operating without this licence is a federal offence under the Ozone Protection and Synthetic Greenhouse Gas Management Act.
2. Ask for a heat load calculation before accepting a quote — A professional technician should perform a heat load calculation — accounting for room size, ceiling height, insulation, window orientation, and glazing type — before recommending a system size. A technician who quotes based on a rule-of-thumb ("you need a 7 kW for that room") is likely to recommend an undersized or oversized unit, both of which increase running costs and reduce comfort.
3. Confirm they hold the correct electrical licence for connection work — Installing a split system or ducted unit requires electrical connection work (hardwiring the indoor and outdoor units, installing an isolator switch). This work must be performed by a licensed electrician or a technician who also holds an electrical licence. Ask the technician whether they will complete the electrical work themselves or engage a separate electrician.
4. Ask about refrigerant type and energy star ratings — Newer systems use R32 refrigerant, which has a lower global warming potential than older R410A units. Ask the technician to explain the energy star rating of the proposed system and compare running cost estimates. A 1-star difference can equate to hundreds of dollars per year in electricity costs for a ducted system.
5. Check whether they offer a maintenance service plan — Air conditioning systems require annual servicing — cleaning filters, checking refrigerant levels, and inspecting electrical connections — to maintain efficiency and warranty coverage. Ask whether the technician offers a scheduled maintenance plan and what it includes, as many manufacturer warranties are voided if the system is not serviced annually by a licensed technician.
