Replacing gas heating with reverse-cycle air conditioning: incentives and tips

Why people are switching

Reverse-cycle air conditioners move heat rather than burning fuel, so they can deliver several units of heat for each unit of electricity used. They also cool in summer, run on your own solar, and — if you remove gas entirely — let you stop paying the daily gas supply charge.

Incentives that may help

• Victoria — Victorian Energy Upgrades has offered discounts for replacing gas heating with efficient reverse-cycle systems, including ducted.
• NSW — the Energy Savings Scheme supports efficient air conditioner upgrades through accredited providers.
• ACT — the Sustainable Household Scheme has offered zero-interest loans; the ACT has also stopped new gas connections in most new developments.
• Elsewhere — check the energy.gov.au rebates finder.

Planning the switch

• Size the system for heating, not just cooling — especially in cold climates.
• Choose a model with good heating performance in your climate zone.
• Check whether existing ducts can be reused, or need replacing.
• Ask about switchboard capacity and electrical work.
• Arrange safe disconnection and capping of the gas appliance.
• Consider replacing gas hot water too, to remove gas completely.

Pairing with solar

Running heating and cooling during the day with solar — for example pre-heating the house in the afternoon — can reduce costs further. Larger solar systems often make sense for all-electric homes; see what size solar system you need.
