Local knowledge

Split systems along the rail line, from Waitara units to Lindfield bungalows

Most split jobs on the Upper North Shore sit close to a station. Hornsby has towers around the station and Westfield, Waitara is mostly newer apartment blocks with a large share of renters, and Gordon and Lindfield have unit blocks along the Pacific Highway. None of these have ceiling space for ducting, so a single or twin-head split is the practical fit. The outdoor unit position is set by the balcony layout and the body corporate, and we work through that approval with you before anything is ordered.

Placement in these blocks is trickier than it looks. Waitara's courtyards and balconies sit between buildings and get little direct sun, so a condenser there works in cool, damp air and needs clear space around it to breathe. Heating matters in these flats too. Winter mornings are cold across the district, and a compact reverse-cycle head in the living room is often the only heating a small unit has, so we size it for July as well as January and check which way the windows face.

In the house streets, splits cover jobs that do not justify ducting. Thornleigh's newer townhouses near the station have tight ceiling cavities, so a multi-head system with one outdoor unit usually serves the bedrooms and the living area. In Normanhurst and St Ives, plenty of homes still run original single-head splits near the end of their working life, and a rear extension or add-on room often needs a head of its own. Owners of the big Federation homes also use a split for a self-contained study that sits apart from the main zoning.

Scope of work & pricing

What's included, and what moves the price

A single-head split for a Waitara or Asquith unit bedroom or living room is $1,800–$3,200 installed, depending on capacity and how far the pipe has to travel to the balcony. A multi-head system with three heads, the usual answer for a Thornleigh townhouse or the bedrooms of a Lindfield bungalow, runs $5,500–$8,500 installed. Book the $99 in-home assessment and the fee comes off the bill when you go ahead.

Frequently asked

Common questions about split system air conditioning in Upper North Shore

Will my Hornsby or Waitara body corporate approve a split system?

Most blocks allow them, but each has its own rules on where the outdoor unit goes, how pipes cross common walls and when trades can work. We give you the unit size, the proposed condenser spot and the pipe route in writing, which is what most strata committees ask to see, and we wait for approval before booking the install date.

Is a split system enough to heat a unit through an Upper North Shore winter?

For a one or two bedroom unit, usually yes. A reverse-cycle inverter split heats efficiently, and in a compact floor plan one head in the living area can carry the flat through cold mornings, with a second head for the main bedroom if it sits at the far end. We check room sizes and window aspect before recommending a capacity.

I rent out a unit in Waitara. Can you handle the replacement for my tenant?

Yes. Tenanted units need a quick, documented swap, so we arrange access with the tenant or managing agent, remove the old unit and leave a written record of what went in. That paperwork suits your property manager and the strata file. Tell us the brand and age of the existing unit when you book so we bring the right bracket and fittings.

Should I use a multi-head or separate splits in a Thornleigh townhouse?

A multi-head system suits townhouses where there is only one sensible outdoor unit position, which is common near the station. One condenser can run heads in the living area and two bedrooms while keeping the courtyard or balcony clear. Separate splits make more sense when rooms sit at opposite ends of the home and the pipe run back to one condenser would be too long.

My St Ives home has an old split that barely copes. Replace it or go ducted?

It depends on how much of the house you want comfortable. If only the living room matters, a new inverter split in the same position is the cheaper fix. If the family wants the bedrooms warm on winter mornings too, the roof space in most post-war brick homes in St Ives suits ducted, and we can quote both options side by side.
