Open space and farmland still frame Heatherton: much of the agricultural land along Old Dandenong Road forms part of one of metropolitan Melbourne’s green wedges, and Victorian Places notes the suburb “has not been greatly affected by metropolitan housing subdivisions”.
The 2021 Census counted 81.7% of occupied dwellings as separate houses. Air conditioning Heatherton homes is therefore mostly a whole-house job: ducted air conditioning, or gas ducted heating paired with cooling, sized to the full floor plan rather than a single room. We install both, and the sizing starts with a free on-site quote.


For a detached house, ducted reverse cycle air conditioning is the whole-home option: one outdoor unit, ducts through the roof space and an outlet in each room, heating in winter and cooling in summer. Sizing is where an install goes right or wrong, so we measure the home and ask which rooms you actually use before recommending a capacity.
Winter deserves as much thought as summer. The Bureau’s Moorabbin Airport station, with 54 years of records from 1971 to 2026, shows a July mean minimum of 6.3°C.
Heritage is unlikely to shape most installs. The suburb has no heritage precinct, just individually listed places such as the Market Gardens Tram Plateway, the former Heatherton Primary School and a house on Kingston Road, and Kingston’s local heritage policy says nothing specific about air conditioning units.
If the house also runs gas hot water, note that from 1 March 2027, when a gas hot water system in an existing home breaks and cannot be repaired, it must be replaced with an electric alternative such as a heat pump, unless an exemption applies. We install heat pump hot water as well, and Victorian Energy Upgrades rebates may apply to eligible upgrades.

Ducted reverse cycle air conditioning heats and cools the whole home from one system, with the indoor unit out of sight in the roof and an outlet in each room. MyAir zoning lets you run only the rooms you are using. We install brands including Daikin, ActronAir, Mitsubishi Electric and Panasonic, and Victorian Energy Upgrades (VEU) rebates may apply to eligible upgrades.
A split system heats and cools one room with no ductwork, and a multi head system runs several indoor units from one outdoor unit. They are a good fit for apartments and smaller homes.
We install and replace gas ducted heating, including Braemar and Bonaire systems, with heat zoned to the rooms you use.
Ducted evaporative cooling brings fresh, cooled outside air through the whole home. We install Coolair and Braemar evaporative systems.
