Campbelltown asks a lot of an air conditioner. Its old weather station recorded 45.8 degrees at one end and minus 5.6 at the other, and July nights averaged 3.2. Reverse cycle covers both, as long as it's sized for the heating as carefully as the cooling. With half of Campbelltown's homes rented, permission often comes first.

Campbelltown's homes

A planned satellite city

Half rented

49.0% of occupied homes were rented, and public housing estates are scattered across the area.

Climate zone 6

On the ABCB's map, the Campbelltown council area is zone 6, the mild temperate zone of Sydney's west.

Renting in Campbelltown

NSW Fair Trading says a tenant can make changes only if the lease allows it or the landlord gives written permission. A split system needs holes through the wall, so it isn't one of the minor changes a landlord can't unreasonably refuse. Fair Trading also notes extra restrictions for social housing and strata properties.

So ask in writing, attach the installer's plan, and say who pays. In social housing, ask your housing provider before booking anyone.

Owners: what to weigh up

In a house, ducted reverse cycle with zones heats and cools the whole place from one outdoor unit; splits suit a home where only a few rooms are used at once. Our split or ducted tool helps you decide. Replacing an old unit? The NSW Energy Savings Scheme may offer an upfront discount through an installer partnered with an Accredited Certificate Provider. See the ESS guide.

What we'd do

Our take for Campbelltown

We'd get the heating capacity at 2 degrees and the cooling at 35 in writing, and choose on both. Renters, we'd sort the landlord's written yes before getting quotes. Send us the job and licence-checked installers in south-west Sydney who do that work will see it; the one who takes it is the only one who gets your details, and if nobody near Campbelltown takes it within 48 hours, installers elsewhere in NSW may see it as well.

Questions people ask

Do Campbelltown homes need heating as well as cooling?
Yes. July nights averaged 3.2 degrees at the old Campbelltown station, and the record low is minus 5.6. A reverse cycle system does both, but check it's sized for the heating as well.
My landlord said no to a split. What now?
A landlord can refuse a change that goes through walls. If you think a refusal of a genuine minor change is unreasonable, NSW Fair Trading says you can take it to NCAT, but a split system usually isn't a minor change.
