Is Split System Installation right for your Willoughby home?
Family homes and units close to Chatswood — and that housing mix shapes the right system choice. Typical Sydney cost: $1,500–$3,500 fully installed

The system we recommend is the one that fits those facts — backed by fixed written pricing and a workmanship warranty.
What affects the price in Willoughby
- Every Willoughby home is different, so honest split system installation pricing has to account for your specific job: home size and ceiling height, insulation and glazing, how many zones or rooms you want conditioned, and the installation access at your property.
- The price ranges above reflect real completed jobs across the North Shore. Your free on-site quote converts them into a single fixed written price for your home — valid for 30 days, no obligation.
Local conditions in the North Shore
- North Shore homes are typically large — four, five, six bedrooms over two storeys — which makes zoning the single most important design decision. A well-zoned ducted system lets you cool the living areas by day and bedrooms by night without paying to condition the whole house.
- Leafy blocks and established gardens also give us flexibility on outdoor-unit placement, and the area's heritage pockets mean we're experienced at discreet, sympathetic installations that keep street appeal intact.

Free on-site assessment
We visit your Willoughby property, measure rooms, check roof space, switchboard and access, and talk through how you use the home.

You receive a system design matched to your home and a fixed written price — itemised, valid for 30 days, no obligation.

Handover & support
We commission the system, walk you through the controls and zoning, and remain a phone call away for warranty and servicing support.
What size split system do I need?
Capacity is measured in kilowatts (kW). Undersized systems run constantly and never quite get there; oversized systems short-cycle, which wears the compressor and leaves rooms clammy. As a general guide for Sydney homes:
- Small bedroom or study (10–20m²): 2.0–2.5kW
- Large bedroom or small lounge (20–30m²): 3.5kW
- Medium living room (30–45m²): 5.0–6.0kW
- Large open-plan living (45–65m²): 7.0–8.0kW+
What affects the price of installation?
- Back-to-back vs complex: simple same-wall installs are the baseline; long pipe runs add cost
- Storey height: second-storey indoor units need scaffolding or brackets
- Electrical: older switchboards may need a dedicated circuit
- Outdoor unit location: ground pad, wall brackets or roof mounting
- Strata rules: apartments may need body-corporate approval before we start
