Who can do the work. Plumbers and gasfitters in Victoria are licensed by the Building and Plumbing Commission, and electrical workers by Energy Safe Victoria. Under the Plumbing Regulations 2018, refrigerated air-conditioning work covers installing, replacing, repairing, maintaining, testing and commissioning the equipment that heats or cools a building, from compressors, condensers and fan coil units to refrigerant pipework, any ductwork and roof flashing the job needs, and split system heat pump water heaters. A restricted mechanical services class covers installing and commissioning single-head splits up to 18 kW of cooling, ceiling cassettes and add-on condensers for ducted systems. Anyone handling the refrigerant also needs an ARC licence: the full licence covers refrigeration and air conditioning work generally, while the restricted split system licence is limited to installing and decommissioning single-head splits and two-part heat pumps under 18 kW. Energy Safe's fact sheet on air conditioning says the electrical work goes to a registered electrical contractor, unless a system is swapped for one of equivalent power in the same spot without altering the cables, which a restricted electrical worker licensed for refrigeration and air conditioning can do. At the end of the install, the customer should be handed a Certificate of Electrical Safety and a plumbing compliance certificate.
Gas, electrification and VEU. Announcing that new homes would go all-electric in July 2023, the Victorian Government said the state has the highest residential gas use in Australia. Since 1 January 2024, planning permits for new homes and residential subdivisions only connect to all-electric networks. Under Victorian Energy Upgrades, activity 6 covers installing a high-efficiency reverse cycle air conditioner, with scenarios set by what's taken out (a ducted gas heater is one of them), and activity 28 covers replacing gas heating ductwork. The Essential Services Commission's activity guide requires the product to be on the VEU Register of Products, a refrigerant with a global warming potential under 700 in units below 15 kW, and, for residential categories, a warranty of at least five years. The same guide says removing a gas heater needs a gasfitter, and the electrical work on a new reverse cycle install needs an A-grade electrician. Providers and anyone marketing for them must not claim to work for the program, the commission or the government, or say an installation is mandatory. Those are the lines a VEU page has to stay inside.
Rentals and apartments. Consumer Affairs Victoria's minimum energy efficiency standards for rentals phase in from 1 March 2027. For cooling, that means a non-ducted electric air conditioner or heat pump with at least a 3-star cooling rating for the climate area, or a ducted system with a Total Cooling Seasonal Performance Factor of 3.8 or more, at the start of a new rental agreement, and in every rental from 1 July 2030. For heating, a fixed heater that fails beyond repair is replaced with a non-ducted electric unit rated at least 2 stars for heating, or ducted electric heating with a Heating Seasonal Performance Factor of 3.2 or more. Every upgrade under the standards is eligible for a VEU discount, and exemptions include installs that heritage laws or owners corporation rules don't permit and, for heating, a property without room for the outdoor compressor. In the City of Melbourne, the council's heritage design guide lists air conditioners among the services and ancillary fixtures it expects to be installed so they can be removed without damaging significant fabric. That council takes in Carlton, East Melbourne, North Melbourne, Parkville and Kensington, among other neighbourhoods.
Heat, noise and call-outs. The Bureau of Meteorology recorded 46.4°C at Melbourne on 7 February 2009, an all-time record for the site, after a late-January run of three consecutive days above 43°C. The Department of Health issues heat health warnings by forecast district when the Bureau warns of a severe or extreme heatwave, and every metropolitan council, from Wyndham to Cardinia and from Hume to the Mornington Peninsula, sits in the Central district. While a warning is current, EPA Victoria's prohibited times for air conditioners don't apply, although a council officer can still judge the noise unreasonable; complaints go to the council, not the EPA. If you take breakdown calls during a heatwave, your home page should say so in its first lines.
Where we fit. WebCraft Studio is an Adelaide team on Hutt St, and we work with Melbourne businesses by phone and email; one of our current clients is a Melbourne coaching practice. We haven't built a site for a heating and cooling business yet, so the examples below are the nearest we have. You send your registration and licence numbers, the suburbs you cover and photos of finished installs, and we send back a draft link to check on your phone.
