From a patchwork of units to a cooling plan for the whole house
In an established family suburb, the question is often not whether to have air con, but how to make the setup you have work better.
Murrumba Downs was once part of Thomas Petrie's Murrumba property, farmed by his family for close to a century. The name comes from a Yugarabul word meaning good or good place. It sits between Fresh Water Creek to the north and the North Pine River to the south, with the Bruce Highway on its eastern side, and its station on the Redcliffe Peninsula line opened in 2016.
It is a well established family area. Undurba State School opened in 1978 and had more than 1,000 students by 2017, and Murrumba State Secondary College followed in 2012. Homes that have been through decades of family life often have air con that was added one room at a time, by different installers, with different brands and very different ages.
A whole-house review often pays off. Replacing the oldest, least efficient units first, sizing each room properly and deciding whether a multi-head or ducted system now makes more sense than five separate splits can lower running costs and tidy up the outside of the house. We look at what you have and give you an honest view on what to keep.
Connex Electrical is based in Mango Hill, right next to Murrumba Downs, and has been installing air con across Moreton Bay since 2014. Also see EV charger installation in Murrumba Downs and Electrician Murrumba Downs.
Which old units should go first?
Units that are noisy, struggle on hot days, leak water, or use older refrigerants are usually the first to replace. We check each one and give you an honest repair or replace view.
If a unit is still working well, we leave it alone and simply service it.
Several splits, multi-head or ducted?
Several separate splits give independent control and spread the risk if one fails. A multi-head puts several indoor units on one outdoor unit, saving wall space outside. Ducted hides the indoor equipment in the ceiling and suits a whole-house approach with zoning.
Multi-head and ducted are quoted after a free assessment.
Tidying up the outside of the house
Years of add-ons can leave a wall covered in pipe ducts, cables and condensers. When we replace units we can remove redundant pipework, consolidate positions and neaten covers so the outside looks cared for again.

Murrumba Downs air conditioning FAQs
Is it worth replacing a 15 year old air conditioner that still works?
It depends on how it performs. If it is noisy, struggles in summer or needs repairs, a modern inverter split will usually be quieter and cheaper to run. If it still cools well and has been serviced, there may be no rush, and we will say so.
Can I convert several wall splits to ducted air con?
Often, yes, if the roof space and layout allow for the indoor unit and ductwork. We assess the ceiling, the switchboard and the zones you want, then quote after a free assessment. Old wall units are removed and refrigerant recovered.
We have four outdoor units on one wall. Can that be tidied up?
Yes. When replacing units we can consolidate them onto a multi-head system or reposition them, and remove redundant pipes and ducts. It is quoted after a free assessment.
Can I use my existing pipework with a new unit?
Sometimes. It depends on the pipe size, its condition and the refrigerant in the new unit. Pipe that is damaged, undersized or has been open to the air is replaced, which protects the new system.
Will my switchboard cope with more air con?
We calculate the load from all your units, not just the new one. If the board has room, a new RCBO circuit costs $180 to $400 incl. GST. If not, a switchboard upgrade costs $1,320 to $3,850 incl. GST.
Do you install air con in extensions and rumpus rooms?
Yes. Extensions often have their own orientation and insulation, so we size the unit for that room specifically. Our sizing guide explains the basics.
Do you also cover Griffin, Lawnton and Kallangur?
Yes. They all border Murrumba Downs and sit close to our Mango Hill base. See our Griffin air con page for newer-home advice.
