Berwick's housing, in numbers
Estate homes
Wikipedia says the rural land around Berwick was subdivided for first-home buyers, with new developments from the 1990s into the 2000s, including the Alira and Timbarra estates.
A country town that boomed
Victorian Places says Berwick was still like a large country town in the mid 1980s. Its population went from 25,461 in 2001 to 44,779 in 2011, and the 2021 Census counted 50,298.
Big houses, mostly mortgaged
52.8% of Berwick homes had four or more bedrooms and 38.1% had three. 46.2% were owned with a mortgage, 28.5% outright and 22.0% rented.
Hardly any apartments
Only 0.3% of occupied dwellings were flats or apartments. Body corporate approvals rarely come into a Berwick job; roof space, zones and power supply do.
What a Berwick house usually needs
Zones that match how you live. A big house with two living areas wastes heat when every vent runs at once. The ACT Government says heating only the rooms in use can be better for efficiency, and ActronAir warns that zoning without the right temperature sensors can end up less efficient. Our zoning and controllers page covers the set-up.
Replacing an original gas heater. If the heater is as old as the house, compare a like-for-like gas unit with ducted reverse cycle. The ACT Government guide says gas ducts are too narrow to reuse for reverse cycle, so switching means new ductwork through the roof. See ducted heating replacement.
Cooling the whole house. Add-on cooling sends cooled air down the heater's own ducts, and Rinnai advises telling your dealer if you might add it later, so a new heater can be sized for it. Ducted reverse cycle does both jobs from one outdoor unit.
Before you sign for a Berwick ducted system
Ask for the duct layout, the zone plan and the outdoor unit's spot in writing. A quote signed at your kitchen table can count as an unsolicited agreement with a 10 business day cooling-off, even though you asked for the visit. Our cooling-off guide explains it. Take your time: a system this size should suit the house for many winters.
What we'd do
If it were our Berwick home
We'd get two quotes that cover the same rooms: a new gas ducted heater with add-on cooling, and ducted reverse cycle with zones. We'd ask each installer for a heat load, a zone plan and photos of the existing ducts, and we'd decide in autumn rather than in the middle of a cold snap.
