Ducted in Fairfield homes

Ducted in Fairfield is mostly a job in the roof of a 1950s or 60s house. The pitched tiled roofs have room for a full-size fan coil and rigid ducting, and because the houses are low-set and rectangular the duct runs are short and even, which helps the system cool the far bedrooms as well as the lounge. We zone by how the house is actually used: the front living areas as one zone, the bedrooms as another, and where a rear extension or sunroom has been added, a third zone so it can be shut off when nobody is in it. The fibro cottages need one honest conversation first: without ceiling insulation the system works twice as hard, so we recommend sorting that before or alongside the install, and size the unit for the house as it is on a 40 degree day.

Heat is the whole design brief here. With no sea breeze the outdoor unit works through a long hot afternoon, so we place it on the south or east side of the house where the shade is, off the concrete that radiates back at it, and clear of the granny flat door if there is one. Running cost is roughly $1–$2 per hour whole-home, and in a Fairfield summer the zoning is what keeps that bill sensible: cool the bedrooms only overnight, run the living zone in the afternoon, and let the inverter idle rather than cycling. In winter the same system heats a low-set brick house far more cheaply than the plug-in heaters most of these homes still rely on when the nights go near zero.
