Split system installation in Kewdale

Kewdale sits in Perth's established inland south-east, a flat, well-serviced suburb close to the airport and freight precincts - and a mix of older homes and infill that each call for a slightly different split-system approach.

Split system air conditioning for Kewdale homes

Much of residential Kewdale is original brick-and-tile from the post-war and mid-century era, often on generous, level blocks. These homes are comfortable to work on, but many still run older switchboards that were never set up for modern air conditioning. As a dual-licensed air conditioning and electrical contractor, Otter Air handles the full job in-house - we run a dedicated circuit and bring the board up to standard at the same visit, so you are not juggling a separate electrician. The most common request we see here is cooling a master bedroom plus the main living zone, where a well-sized split system does the heavy lifting without the cost of full ducted.

Being inland and away from the coast, Kewdale gets the hotter, drier end of Perth's summer, with long stretches of heat building through the afternoon and little sea breeze to take the edge off. That makes correct unit sizing and condenser placement genuinely matter - an undersized system simply runs flat out and never catches up. We position outdoor units for airflow and quiet running, and keep line runs tidy and as short as the layout allows.

Kewdale's newer infill and double-storey rebuilds bring their own considerations: routing line sets to upstairs rooms and, in some cases, a multi-head setup to cool several rooms from one outdoor unit. Whether you are replacing a tired old wall unit or fitting out a renovated home, our air conditioning Kewdale service covers honest sizing advice, clean cable runs and full electrical compliance from the one team.

“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.”
