About

Reverse Cycle Notes is an independent information site for Australian households pricing a heating, cooling or hot water upgrade. It explains how installers price split, multi-head and ducted reverse cycle systems and heat pump water heaters, how national and state incentives work, what the Victorian gas rules mean for existing homes, and how to compare running costs with the arithmetic shown.

The site is written for owner-occupiers, landlords and renters who want to understand a quote before they sign. It covers residential systems only. It does not cover commercial HVAC maintenance, rooftop solar or batteries in depth, or insulation and windows, except where they affect sizing and running costs.

All prices and savings are illustrative examples to show the method, not market rates, quotes or recommendations. Incentive programs, licence rules and gas policy change, so every guide names the official source to check. We do not rank brands or installers, and we do not receive payment for leads from incentive providers. Nothing here is financial, legal or technical advice; for safety issues or disputes, contact a licensed tradesperson, your state regulator or a consumer agency.
