Baulkham Hills homes, by the numbers
Mostly houses
At the 2021 Census, 75.4% of occupied homes were separate houses, 13.3% semis or townhouses and 11.3% flats or apartments.
Plenty of rooms
48.3% of dwellings had four or more bedrooms, and the average was 3.5. That's a lot of house for one system to heat and cool evenly.
Owners, for the long haul
32.6% of homes were owned outright and 43.0% with a mortgage. Only 22.3% were rented, so most households can make the call themselves.
Suburban since the 1960s
The area was land grants and farms until urban development sped up from the 1960s.
Western climate
The ABCB's map puts The Hills Shire in climate zone 6. AdaptNSW says Western Sydney averages 10 to 20 days a year above 35 degrees and 10 to 20 nights below 2.
Ducted or splits for a Baulkham Hills house?
Ducted reverse cycle heats and cools the whole house from one outdoor unit, with zones to separate bedrooms from living areas. ActronAir says zones can differ by only 4 degrees and the system runs in one mode at a time.
Splits suit a house where only two or three rooms are used at once. The ACT Government says several splits can be zoned simply by switching on the ones you need. Our split or ducted tool helps you weigh it up.
Coming off gas ducted heating? The ACT Government guide says the old gas ducts can't be reused for reverse cycle: they're too narrow and may have age-related problems. Allow for new ductwork in the quote.
Before you sign a Baulkham Hills quote
- Is the heat load worked out room by room, including the west-facing rooms?
- How many zones, which rooms are in each, and where do the temperature sensors go?
- Does the house need a switchboard upgrade or 3-phase power for this system?
- What insulation rating will the ducts have? The ACT Government recommends at least R1.5.
- What heating output does it give on a near-freezing morning?
What we'd do
If it were our Baulkham Hills home
We'd decide how the house is actually used before choosing a system. If most rooms are busy on winter evenings, we'd go ducted reverse cycle with sensible zones; if it's mostly the living room and a couple of bedrooms, we'd price good splits too. Either way we'd want a specialist who designs whole-house systems for Hills District homes. Licence-checked installers like that can see your job, and the one who takes it is the only one who gets your details. If 48 hours pass with no taker near Baulkham Hills, the job may be shown to installers elsewhere in NSW.
