What's different about Narellan
Some of Sydney's coldest nights
Camden Airport's July mean minimum is 3.0 degrees, against 8.9 at Observatory Hill in the city. In the far west, places such as Camden and Richmond see a relatively large gap between day and night temperatures.
Climate zone 6
The ABCB's map shades the Camden council area as zone 6, mild temperate, along with Campbelltown, Liverpool and Penrith. It's a heating-and-cooling climate, not a cooling-only one.
Houses on former farmland
Narellan sits about 60 km south-west of the CBD at 90 m above sea level. Farmland gave way to suburban growth here, and at the 2021 Census 90.6% of homes were separate houses.
A good share of renters
36.6% of Narellan homes were rented in 2021. If that's you, the owner decides on any new system, so start with the agent.
Old estates nearby
Studley Park, Camelot (Kirkham) and Kirkham Stables are heritage-listed sites in Narellan. If your home is on or next to one, check with Camden Council before an outdoor unit goes up.
What a Narellan ducted quote should show
- The heating capacity in kW as well as the cooling capacity, and how it was worked out for your house
- How many zones, and which rooms are in each, so you can heat bedrooms at night without heating the living area
- Where the outdoor unit goes, with air around it and room to service it
- What happens to any old ducts or heater, including removal
- The installer's NSW licence number and the business's ARC RTA number, which starts with AU
Why heating capacity is the number to watch
Mitsubishi Electric says an outdoor unit gathers frost in cold, damp weather and pauses for up to 10 minutes to clear it. That's normal, so don't mistake it for a fault on a cold Narellan morning.
Rinnai warns that an undersized system gives too little heating or cooling and wears out sooner, while an oversized one short cycles. A ducted specialist should show you the working. Our ducted air conditioning in Sydney page and the zoning guide go further.
What we'd do
Our take for Narellan
We'd treat heating as the main job and cooling as the second, and we'd ask for both capacities in writing. We'd zone the bedrooms separately for those cold nights. If the house came with an older system, we'd get a quote that sets repair beside replacement. Then we'd want a ducted specialist who works in the south-west. Send us the job: licence-checked installers near Narellan who do that work will see it, and only the one who takes it gets your contact details. If nobody close to Narellan takes it within 48 hours, installers elsewhere in NSW may see it too.
