Split system installation in Kelmscott

One of Perth's older south-east suburbs, Kelmscott spreads along the Canning River and up against the foothills - and its long-settled brick homes and bigger semi-rural blocks each ask something different from a split system.

Split system air conditioning for Kelmscott homes

A big share of split system installation Kelmscott work lands on the established brick-and-tile homes that have been here for decades. These are solid houses, but they were built long before high-draw aircon was the norm, so the most common surprise isn't the wall - it's the meter box. Older switchboards through this part of the City of Armadale often have no spare capacity, and a new high-output head needs its own dedicated circuit. Because Otter Air is dual-licensed for both air conditioning and electrical, we run that circuit, upgrade a tired board where it's needed, and mount the indoor and outdoor units in the one visit - so you're not left chasing a separate sparky after the aircon crew has packed up.

Kelmscott also has plenty of the larger, semi-rural blocks that run toward the foothills, plus a steady stream of newer double-storey builds on infill subdivisions. The bigger properties often mean the ideal condenser spot sits a fair way from the room being cooled, so we plan line runs and drainage carefully rather than forcing the unit somewhere awkward. Two-storey homes usually want cooling upstairs as well as down, where a well-sized multi-head system - one condenser, neat runs through the roof space or cavity - beats bolting boxes onto every wall.

Tucked inland against the Darling Scarp, Kelmscott gets long, hot, still summers with little of the sea breeze the coast enjoys, so correct sizing matters more than corrosion here. Whether it's a fresh install, cooling a master and main living zone, or replacing a tired old unit that's lost its bite, we give honest, upfront advice on air conditioning Kelmscott households can rely on.

“Phenomenal service provided by Matt! The works was done on schedule and to a professional standard. The price was also very reasonable for the works done. I highly recommend for anyone looking to get aircon work done, and I wish Otter Air Conditioning the best for their future endeavours.”
