Cherrybrook's 1980s and 90s estate homes were built big before ducted air became standard, which makes it one of northern Sydney's busiest retrofit suburbs. We fit high-capacity zoned systems into two-storey floorplans, manage the three-phase question early and keep metro-station-driven renovations on schedule.
From the first quote to commissioning, residential air conditioning in Cherrybrook is carried out by NSW-licensed contractor partners under Quotcha's coordination.
What we do
Cherrybrook is part of our wider Hornsby Shire air-conditioning service area.
Local context
Local conditions change what split system air conditioning in Cherrybrook costs to install and service, and what ducted air conditioning in Cherrybrook involves.
Typical Cherrybrook homes run 250 to 350 square metres over two storeys. Whole-home comfort needs 16kW to 20kW ducted capacity with day-night zoning; anything smaller ends up running flat out on February afternoons.
Larger systems, pool equipment and EV chargers stack up quickly against a single-phase supply. Many Cherrybrook installs either add three-phase or specify load management; we model the whole household load, not just the AC.
Several estates have covenant expectations about visible external equipment. Side-elevation condenser placement and colour-matched conduit keep installs neighbourly and compliant. The display-village estates off Shepherds Drive wrote those expectations into their sale contracts, and long-term residents still hold newcomers to them.
Since the metro opened, renovation activity has surged. Coordinating AC rough-in with builders mid-renovation is routine for us, and always cheaper than cutting into fresh plasterwork afterwards. The 2019 station opening reset what buyers expect of these homes.

FAQs
Most need 16kW to 20kW with at least four zones. The deciding factors are ceiling insulation quality, window area facing west and whether the home office and bedrooms run simultaneously. A room-by-room load calculation settles it; floor-area rules of thumb consistently undersize these homes.
Above roughly 16kW, three-phase becomes the clean answer, and if a pool heat pump or EV charger is on the horizon it is worth doing once. Smart load management can defer it on smaller systems; we price both paths so you can decide with real numbers.
Far less than its size suggests when zoning is used properly. Running two of five zones draws a fraction of full capacity, and an inverter throttles down once rooms reach temperature. The expensive habit is cooling all 300 square metres to sleep in two bedrooms; set schedules and let the zones work.
For a typical bedroom (10–15m²), a 2.0–2.5kW split system is sufficient. Living areas (25–40m²) generally need 5.0–7.0kW. Open-plan living/kitchen areas may need 7.0–9.0kW. West-facing rooms with afternoon sun exposure should size up by 0.5–1.0kW. A proper heat load calculation is recommended.
