Cooling a Hendra family home

Air conditioning a Hendra home usually starts with one question: whole-house ducted or a split in each room? Around 80% of homes here are detached houses, many of them older timber places and Queenslanders on jacaranda- and poinciana-lined streets. Ask three installers and you’ll probably get three answers, and at least one of them won’t ring back.

Pick wrong and you’re either cooling rooms nobody’s in, or living with a wall unit that can’t reach the hallway and bedrooms.

That’s where we come in. We’ve vetted the installers already, so you get one who works on timber homes, explains the trade-offs plainly and quotes upfront.

Hendra began as farmland growing citrus, grapes and pineapples, with dairies too, before estates such as the 1887 Hendra Railway Station Estate and the 1926 Petersen Estate carved it into house blocks. Roughly three in four homes are owner-occupied, so most aircon jobs in Hendra are long-term decisions rather than quick landlord swaps.

Ducted or splits? How it usually shakes out

Ducted makes the most sense when you want most of the house cooled, there’s workable roof or underfloor space, and you’d rather have discreet vents than wall units. Zoning lets you shut off rooms you’re not using. For a larger family home, zoned ducted often lands around $12,000 to $22,000, indicative only.

Splits win when you only need two or three rooms done, when the roof space is tight, or when you’d like to start with the main bedroom and add more later. In an older timber house without insulation, a split per room is often the more efficient choice, because you only cool the space you’re actually in.

Common questions

Hendra aircon FAQs

My Hendra house is old timber with no ceiling insulation. Will aircon even work?

It will, but it has to work harder. Uninsulated ceilings and timber walls let heat in quickly, so the installer should size for that rather than floor area alone. Many owners start with bedroom splits and look at insulation separately. A properly sized inverter unit in a closed room still makes a real difference on a humid night.

Which aircon setup should a four-bedroom Hendra family look at first?

It depends on how you use the house. If everyone’s home in the evenings and you want most rooms cool, zoned ducted is popular. If it’s mainly bedrooms at night, separate splits can cost less to buy and run. Ask the installer to quote the option they’d recommend and explain why it suits your layout.

We’re renovating. Should we replace our old aircon at the same time?

Often, yes. If the old unit is over 12 to 15 years old, uses R22 refrigerant or struggles on hot afternoons, a renovation is a good moment to swap it, especially while walls are open for new pipe routes. Modern inverter systems use less power for the same cooling. Our aircon replacement page has indicative costs.

Is the industrial pocket in north-east Hendra covered too?

Put it in the form and we’ll look for the right person. For workshops, offices and small commercial spaces, we look for an installer who does commercial air conditioning rather than only home splits. Give us the rough floor area, how many people use the space and whether there’s three-phase power, and they’ll come back with a written quote.
