An old rail town, a new university precinct and every kind of house in between
Petrie's housing tells the story of the suburb, and each chapter needs a slightly different air con plan.
Petrie grew from Tom Petrie's Murrumba homestead on the Pine River, founded in 1858 as a stop on the road to the Gympie goldfields. The town was known as North Pine until the station took the Petrie name in 1911. The housing boom came after the APM paper mill opened in December 1957 on old dairy land.
That means many streets are lined with homes from the second half of the twentieth century, often built when a ceiling fan was the only cooling anyone expected. Newer housing has since gone in on former pine plantation and farmland, and the mill site itself is now home to the University of the Sunshine Coast Moreton Bay campus, opened in 2020, inside The Mill at Moreton Bay priority development area.
For air con, that mix matters. A mid-century home may have a small switchboard and solid walls that rule out some unit positions. A newer home usually has a modern board and easy roof access. A shop or office near where Gympie Road, Dayboro Road and Anzac Avenue meet has different hours and heat loads again.
Connex Electrical is based in nearby Mango Hill, a short drive from Petrie, and has been installing air con across the old Pine Rivers district since 2014. Also see EV charger installation in Petrie and Electrician Petrie.
Homes from the mill era
Homes built from the late 1950s onward often have a switchboard that predates modern safety switches, so we check the board and spare capacity first.
If there is room, a new RCBO protected circuit costs $180 to $400 incl. GST. If not, we explain the switchboard upgrade options so you can decide before anything is booked.
New builds on former farm and plantation land
Newer Petrie homes tend to be the simplest installs, with spare board capacity and lightweight walls, so a standard back-to-back split is often possible. Larger homes may suit multi-head or ducted, quoted after a free assessment.
Shops, offices and consulting rooms
Small commercial spaces need a unit sized for people, equipment and afternoon sun through shopfront glass. The building owner may also need to approve the outdoor unit position.

Petrie air conditioning FAQs
My Petrie house was built in the 1960s. Can it take a split system?
Usually yes, but we check the switchboard and wiring first. Many older boards have space for a new protected circuit, which costs $180 to $400 incl. GST. If the board is full or outdated, we explain the upgrade options before quoting the install.
Can you install air con in my shop or office near the Petrie town centre?
Yes. We install wall split systems in small shops, offices and consulting rooms, quoted after a free assessment because glass, equipment and occupancy all change the unit size. The building owner may need to approve the outdoor unit position.
I rent a room to a student. Is a small split worth it?
For a single bedroom, a small inverter split is an efficient way to keep a tenant comfortable without cooling the whole house. A 2.5 kW unit suits many standard bedrooms, but we confirm the size using the room, windows and orientation. Our sizing guide explains the basics.
Which wall is best for the indoor unit in an older home?
Ideally an external wall with a clear outdoor area behind it, so the install stays back-to-back and at the standard price. Solid internal walls or brick between rooms can mean a longer pipe run, which is quoted after a free assessment.
Should I choose a split or ducted system for a new Petrie home?
If you mainly want to cool bedrooms and one living area, separate splits are often the most cost-effective. For most of the house with discreet ceiling outlets, ducted may suit better. Our guide to the best air conditioner for Queensland helps you compare.
Do you cover Lawnton, Kallangur and Dakabin as well?
Yes. Those suburbs surround Petrie and sit within easy reach of our Mango Hill base, so we work in all of them regularly.
