Bunbury needs both: cooling for warm to hot, dry summers and heating for cool, wet winters, when the rain peaks from May to September. That makes reverse cycle the natural fit for a lot of homes, with evaporative worth weighing for dry summer afternoons. Living near the harbour, the bay or the open ocean changes how an outdoor unit should be protected.

Bunbury's heating and cooling facts

Summer and winter

Bureau of Meteorology-sourced averages for Bunbury (1995 to present) give a mean maximum of 29.9 degrees in January and 30.0 in February, and a July mean minimum of 7.3.

Humidity

Afternoon humidity averages 44% in January and 65% in July. Summer afternoons are a touch more humid than Perth Metro's 39%, and winters are damp.

Climate zone

NCC 2016 puts Bunbury in zone 5, warm temperate, the same as Perth. Albany and Pemberton, further south, are zone 6.

Three kinds of water

Geographe Bay curves from Cape Naturaliste and ends near Bunbury, sheltered from Indian Ocean swells by the cape. The GAA's corrosion guide rates calm salt water such as a harbour foreshore as C4, 50 m to 1 km back from a sheltered bay as C3, and the first 200 m from a surf beach as C5.

Housing

At the 2021 Census, 76.2% of the City of Bunbury's occupied homes were separate houses, 19.1% townhouses, terraces or semis and 3.7% flats or apartments. More than a third (34.1%) were rented, a bigger share than Greater Perth's 26.6%.

Gas

ATCO's Mid-West and South-West gas distribution systems serve Bunbury, so gas heating is an option where your street is connected.

The jobs that come up most in Bunbury

Reverse cycle for both seasons. Splits and ducted systems suit a climate that needs summer and winter covered, and the heating side deserves as much attention as the cooling when July nights average 7.3 degrees. Compare the red heating stars on the energy label as carefully as the blue.

Servicing, especially near the water. Salt works on outdoor coils and casings, and which water you live near changes how hard. See air conditioning service in Bunbury.

Evaporative, with care. It can work on dry summer days, but CHOICE says it isn't recommended for humid or wet climates, and Seeley says reverse cycle copes better with coastal and mixed weather. Get an honest view from an installer who fits both.

Rentals. With about a third of Bunbury homes rented, plenty of jobs start with a landlord. Any new install is the owner's decision, so a written OK comes first.

Low-lying homes near the water

When ex-tropical cyclone Alby passed on 4 April 1978, water breached Bunbury's sea wall, flooding 100 homes, and 130 residents were evacuated. If your outdoor unit sits on the ground in a low spot close to the water, ask the installer whether a raised pad or a wall bracket would be the safer place for it.

Who does the work

WA's rules apply here as in Perth. The refrigerant side needs an Australian Refrigeration Council licence, and the switchboard protective device and fixed wiring for a new unit need a licensed electrical contractor, whose EC number belongs on their ads and vehicles. The WA licence page covers it in more detail.

What we'd do

Our take for Bunbury

We'd choose a reverse cycle system on its heating figures as much as its cooling, because Bunbury's wet winters ask for both. Near the harbour or an ocean beach, we'd want coastal coil protection and a yearly service that includes the outdoor unit. And if a cooler was on the table, we'd have someone who installs both kinds talk us through which suits our street.

Questions people ask

Is evaporative cooling a good idea in Bunbury?
It can be on dry summer days. Bunbury's January afternoons average 44% humidity, a little higher than Perth Metro's, and CHOICE doesn't recommend evaporative for humid or wet climates. Our evaporative or refrigerated guide helps you decide.
Does living near the bay affect my outdoor unit?
Yes, and how much depends on which water. The GAA rates calm harbour foreshores as C4, and surf beaches as C5 for the first 200 m. See our coastal homes guide.
Do I need heating in Bunbury?
Most homes will want it. July nights average 7.3 degrees and the winters are wet. Reverse cycle or gas both work, and Bunbury is on ATCO's gas network.
Who can install air conditioning in Bunbury?
An ARC-licensed technician for the refrigerant, plus a licensed electrical contractor for the switchboard and fixed wiring, as WA requires everywhere. You can check the electrical licence on Building and Energy's online search.
