Covering North Rocks and the Hills District.
North Rocks is big established brick homes, and most of our work is replacing ageing ducted.

North Rocks is a settled, leafy pocket of big brick homes from the 60s through the 80s, a lot of them on generous blocks near the Parramatta side of the Hills. They run ducted, and most of the systems are now well into replacement age. That's the bulk of our North Rocks work. We've done the Hills since 1991 with our own crew.

Replacing Ageing Ducted in a North Rocks Home

Most of the big brick homes here are on a ducted system that's now twenty-plus years old. Once the compressor or board goes it's not worth chasing, and a modern inverter cools the big floor plans far better for less. The ducting in these deep roof cavities is nearly always sound, so a replacement is mostly new units and a controller. We also retrofit ducted into the homes that never had it.

We run Panasonic, Daikin and Actron, Mick runs the Hills installs since 2009.

Check our sizing calculator and pricing guide. We also cover Baulkham Hills, Northmead and North Parramatta, and for repairs see our ducted repairs page. Our main North Rocks page covers all our local services.

Ducted Replacements in North Rocks

Replacement is most of what we do in North Rocks. The big brick homes here are nearly all on an ageing ducted system, and once it's twenty-plus years old and dropping parts, a new inverter is the smarter spend. The ductwork usually stays, so a ducted air conditioning replacement in North Rocks is mostly new units and a controller, often a one-day job.
