How much does air conditioning cost in Geelong?
Split systems are what Geelong searches for most, and supplied and installed they cost $1,125–$2,325 for a 2.5 kW bedroom unit, $1,300–$2,600 at 3.5 kW and $1,675–$3,250 for a 5 kW living-room model. A big open-plan area takes the 7 kW size at $2,050–$4,175, and a basic ducted system serving every room costs $7,450–$13,000. With July days averaging just 14.4 °C (BOM averages), the heating side of a reverse-cycle unit matters here at least as much as the cooling, and that changes how it should be sized. GST is included.

Geelong air conditioning: a split per room or ducted, two splits or a multi-split, and the climate
A split in each room or ducted, in a Geelong house
Three 3.5 kW split systems, supplied and installed, come to $5,850 at the typical price in our Geelong table, against $7,450–$13,000 for a basic ducted system and $11,150–$20,450 for a premium zoned one. Most Geelong homes are houses: in the ABS 2021 Census 86.7% of dwellings in Geelong are separate houses, the highest share of the 15 cities we cover.
Two splits or a two-head multi-split in Geelong
A two-head multi-split is $3,725–$7,000 installed in our Geelong table. Two separate 2.5 kW splits come to $3,350 at the typical price, less than the multi-split's typical $5,100. A four-head multi-split is $6,500–$11,150.
Geelong's climate zone and rainfall
Geelong is in zone 6 of the Australian Building Codes Board climate map, mild temperate, and is the driest of the 15 cities we cover, with 510.3 mm of rain a year on Bureau of Meteorology averages.

What Affects Air Conditioning Costs in Geelong
Size it for July, not January
January, Geelong's warmest month, averages 26.0 °C, while July reaches only 14.4 °C and falls to 6.4 °C overnight (BOM averages). Heating is the bigger job, so ask the installer to size the unit for a winter evening; one that can warm the room in July will handle summer without strain. The heat-load calculation belongs on the written quote, not a guess from the floor area.
VEU discounts for leaving gas heating
Victorian Energy Upgrades offers as much as $1,610 off when an efficient reverse-cycle system takes over from a gas room heater that is not ducted, rising to $5,530 where it replaces or removes ducted gas heating. Every Victorian household can claim it, private rentals included, as long as any system being replaced is more than 2 years old and the new unit carries at least a 5-year warranty.
Working with an accredited provider
The VEU discount comes through an accredited provider, who confirms which models qualify, puts the discount in the quote and handles the paperwork. If you would rather use your own installer, they must team up with an accredited provider before any work starts. Disconnecting an old gas heater is gasfitting work, and the Building and Plumbing Commission is the body that licenses gasfitters.
Three-bedroom houses and ducted
Stand-alone houses are 86.7% of Geelong dwellings, and 46.4% have three bedrooms, where the national share is 39% (ABS 2021 Census). That is the home a basic ducted system at $7,450–$13,000 is built around, and zoning so bedrooms and living areas run separately costs $11,150–$20,450. Without roof space for ducts, a four-head multi-split is $6,500–$11,150.
Back-to-back or a long run
The simplest split install is back to back, with the head inside and the condenser outside sharing a single wall. Long pipe runs, a second storey or a condenser on a bracket or roof all add labour. Each unit needs its own circuit, run by an electrician licensed with Energy Safe Victoria, so have any switchboard work priced up front. Fitting a unit you bought yourself is $650–$1,400.
Swapping out an old unit
Swapping a tired split for the same type, with the old one taken away, costs $1,400–$2,800; removal and disposal on its own is $93–$325. Ducted evaporative cooling for the whole house is $2,600–$6,500, but it only cools, so it does nothing for Geelong's winters and does not qualify for the VEU reverse-cycle discount.
Keeping it running
Servicing a split, clean included, is $93–$300, and a ducted system service $185–$510. Small repairs run $140–$465, while a regas or bigger fault costs $280–$1,125. In Geelong a reverse-cycle unit often works through both seasons, so a service fits best in the gap between winter heating and the first hot spell of summer.
