Ducted in Dulwich Hill homes

Ducted reverse-cycle in Dulwich Hill is mostly a Federation bungalow job. These houses have hipped terracotta roofs with enough cavity height for a fan coil above the hallway and flexible duct out to the bedrooms and the rear living extension most of them have picked up over the years. Slate roofs and the semis are tighter, and there we look at a slim-line chassis or a bulkhead run before we rule ducted out. The outdoor unit goes to the rear yard or the side passage, which suits the heritage streets around Arlington Oval where nothing can be visible from the footpath, and it keeps the compressor away from the front bedrooms.

Zoning matters here because of how the heat behaves. Dulwich Hill's inland position means the afternoon breeze that cools the harbour suburbs rarely reaches these streets, so the west-facing rooms hold heat into the evening while the shaded front rooms stay comfortable. A four-zone layout that separates living areas from bedrooms, and the western rooms from the eastern ones, lets a family cool only the rooms in use and keeps the running cost near the roughly $1–$2 per hour whole-home figure. For homes on the Marrickville side under the flight path, ducted also solves the closed-window problem in every room at once instead of one split at a time.
