Split Systems & Refrigerated Ducted — We Install Both.

All Electric Homes installs the full range of residential reverse-cycle HVAC systems — from single-room split systems to whole-home refrigerated ducted solutions replacing existing gas heating infrastructure.

Single Zone
Reverse-Cycle Split System
Best for: Targeted room heating/cooling

Wall-mounted indoor unit with outdoor compressor. Heats and cools a single zone with exceptional efficiency. Ideal for living rooms, bedrooms, or open-plan spaces. Available in capacities from 2.5kW to 9kW per unit.

  • Heats and cools — one unit, one installation
  • COP of 3.0–5.0+ (highly efficient)
  • App and smart-home compatible on most brands
  • Quiet — under 22 dB indoor on select models
  • Multi-split options for 2–5 zones
  • Solar-schedulable on compatible systems
Whole-Home
Refrigerated Ducted System
Best for: Gas heating replacement

A refrigerated ducted system uses the existing ductwork from your gas ducted heater to deliver heating and cooling to every room from a single outdoor unit and central controller. The most complete gas heating replacement available.

  • Full home heating and cooling — one system
  • Uses existing ductwork (in most cases)
  • Zone control — heat or cool individual rooms
  • Eliminates gas ducted heater entirely
  • Qualifies for Victorian rebates
  • Annual service plan available from AEH
Why Replace Gas Heating

Why Reverse-Cycle Beats Gas Ducted Heating.

Gas ducted heating was the Victorian standard for decades — but reverse-cycle air conditioning now outperforms it on cost, efficiency, comfort, and emissions. Here's the comparison.

400%

Dramatically More Efficient

A reverse-cycle system delivers 3–4 units of heating for every 1 unit of electricity consumed. A gas heater converts at best 85% of gas energy to heat — and releases the rest as flue gas.

❄️
Both

Year-Round System

Gas heating only heats. Reverse-cycle provides both heating in winter and cooling in summer from the same system — replacing your need for a separate air conditioner.

💰
$900/yr

Lower Running Costs

A Victorian household replacing gas ducted heating with reverse-cycle saves approximately $700–$1,100 per year on heating energy costs — and eliminates the gas supply standing charge.

🌿
60%+

Lower Emissions

On Victoria's current grid, reverse-cycle heating produces approximately 60% fewer emissions than gas ducted heating — a figure that continues to improve as renewable generation increases.

☀️
Solar

Solar Compatible

Pre-heat or pre-cool your home during peak solar generation hours. Reverse-cycle uses electricity — meaning you can effectively heat your home from your own rooftop solar system.

🏠
Safer

No Combustion in the Home

Gas ducted heating burns fuel inside the home. Reverse-cycle produces no combustion gases, no CO risk from flue degradation, and no particulate emissions.

Common Questions

Frequently Asked Questions

Can a refrigerated ducted system use my existing ductwork?
In most cases, yes. Existing ductwork from a gas ducted heater can be repurposed for a refrigerated ducted system — this significantly reduces installation cost and disruption. AEH inspects the existing ductwork during the assessment to confirm condition, sizing, and suitability. In some older homes, ductwork may require partial replacement or supplementation, which AEH will identify and quote for upfront.
Does reverse-cycle heating work in cold Victorian winters?
Yes. Modern reverse-cycle air conditioners are designed to operate effectively down to -15°C ambient temperature — well below Melbourne's coldest overnight temperatures. Heating performance (COP) does reduce slightly in extreme cold, but remains significantly more efficient than gas heating at all temperatures encountered in Victoria. AEH sizes systems to maintain comfortable indoor temperatures on the coldest Victorian days.
What brands does AEH install for ducted systems?
AEH installs leading refrigerated ducted HVAC brands including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, and ActronAir. Brand selection is based on system performance, warranty terms, and suitability for your home configuration. For split systems, AEH works with the same brands plus Samsung and LG. Your consultant will recommend options across price points during the quoting process.
How much can I save replacing gas ducted heating with reverse-cycle?
Savings vary by household, system size, and usage pattern. A Victorian household replacing a gas ducted heater (including gas standing charge) with a reverse-cycle system typically saves $700–$1,100 per year on heating energy costs. If solar panels are paired with the new system, pre-heating or pre-cooling the home during solar generation hours reduces running costs further — often close to zero on mild days.
How long does a refrigerated ducted installation take?
A full refrigerated ducted installation (including removal of the old gas heater) typically takes 1–2 days for a standard residential home. The gas line is capped on day one, and the new system is installed and commissioned within the same visit or the following day. AEH coordinates all trades — refrigeration mechanic, electrician, and plumber if gas capping is required — in a single managed project.
Do reverse-cycle systems require regular maintenance?
Yes. Reverse-cycle systems should have filters cleaned every 1–3 months (a simple task the homeowner can do) and professional servicing annually. Annual servicing checks refrigerant levels, cleans the coil, inspects electrical connections, and ensures the system is operating at rated efficiency. AEH offers annual service plans for all installed systems. Regular servicing extends system lifespan and maintains manufacturer warranty.
