Northwind Climate was founded in Chatswood and has been the go-to HVAC specialist across the North Shore and Northern Beaches for over fifteen years. We work exclusively on residential projects — no commercial shortcuts, no apprentice-only crews, no subcontracting the parts that matter.

Every system we install is custom-designed to the thermal load of your home. That means properly sized equipment, correctly designed ductwork, and commissioning that goes beyond a factory-default controller handover. We're not here to sell you the biggest unit. We're here to give you the quietest nights, the most consistent temperatures, and the lowest running bill we can engineer.

All work is carried out by fully licensed technicians. ARC-certified refrigerant handling as standard. Every installation comes with our 10-year workmanship warranty — backed in writing, not just claimed on a website.

What we do

Full-scope
climate services

From a single reverse-cycle split to a whole-home ducted system with zoning and smart control — we design, install, service, and repair it all.

Ducted Air Conditioning
Whole-home climate control with concealed ductwork, zoned control, and near-silent operation. Designed to the thermal load of your specific home — not the builder's default spec.
Learn more
Reverse-Cycle Split Systems
Premium wall-split and floor-console systems from leading manufacturers. Efficient year-round heating and cooling for individual rooms or open-plan living spaces.
Learn more
Multi-Head & Zoning
One outdoor unit, multiple indoor heads — each zone independently controlled. Ideal for double-storey homes or additions where ducted isn't practical.
Learn more
Smart Home Integration
Control your climate from anywhere with HomeKit, Google Home, or BACnet-compatible controllers. Scheduled, sensor-driven, or voice-activated — we commission it properly.
Learn more
Servicing & Maintenance
Annual service plans that keep your warranty intact and your system running at peak efficiency. Filter cleans, coil inspections, refrigerant checks, and full performance reports.

Fault Diagnosis & Repair
Warm air when you need cooling? Unit won't start? We diagnose and repair all major brands. Same-day callouts available across the North Shore when booked before noon.

How we work

From first call to
final commission

01
Site assessment
We visit your home, assess the thermal load, inspect your ceiling and wall cavities, and understand how each room is actually used. No call-centre quoting — every design begins in person.
02
Custom design
We calculate the correct system size using AS/NZS 3823 methodology — not rule-of-thumb. You receive a written design brief including equipment selection, duct routing, and zoning logic before a cent is committed.
03
Clean installation
Our technicians install to builder-grade finish standards. Penetrations are sealed, cables are concealed, and outdoor units are located and mounted for minimum visual and acoustic impact.
04
Commissioning & handover
Every system is tested at full load before we leave. We walk you through zoning, schedules, and the controller — not a QR code to a YouTube video. Warranty documentation is provided on the day.

A cross-section of the work we do across the North Shore — from heritage terrace restorations to new Killara double-storeys.

Ducted · Zoned
Whole-home ducted — Killara
12.5kW inverter ducted system, 6-zone control, fresh-air intake. Installed during renovation — all ductwork concealed in the new ceiling void. Sub-40dB in every bedroom.

Multi-head
5-head multi-split — Mosman
Heritage home — no ceiling cavity access. Single slim outdoor unit, five wall-mounted heads. Each room independently controlled. Piping concealed in custom-painted conduit channels.

Smart · Ducted
Smart-zoned ducted retrofit — Pymble
Replaced a failing 1990s central system with a modern 16kW inverter ducted unit and 8-zone motorised damper control. Integrated with the owner's Apple HomeKit system — temperature is managed by room-occupancy sensors and a custom schedule. Running cost dropped 34% versus the old system in the first summer of operation.

What North Shore
homeowners say

The whole-home ducted system Northwind installed last winter has been genuinely transformative. The bedrooms are so quiet you can barely tell it's on — and it hit the temperature set-point in under twelve minutes on a 38-degree day. Couldn't recommend more highly.

Killara · Ducted installation
We have a 1920s Mosman home with no ceiling cavity, and every other quote we got was a disaster of exposed piping or "not really possible." Northwind designed a multi-head solution that's essentially invisible. The attention to the piping routing was extraordinary. Worth every dollar.

Mosman · Multi-head installation
Annual service for three years running and we've never had an unplanned breakdown. The written condition reports are a nice touch — our strata committee actually uses them as part of the building's maintenance log. Genuinely professional operation.
