Split system installation in South Lake

Split system air conditioning for South Lake homes

South Lake took shape through the 1970s and 80s, so the streets are dominated by single-storey brick-and-tile homes on standard suburban blocks. These houses suit a wall-mounted split well, but the original switchboards often weren't built with reverse-cycle air conditioning in mind. Adding a dedicated circuit, and upgrading an ageing board where needed, is routine work for us. Because Otter Air is dual-licensed in both air conditioning and electrical, the whole job stays with one team rather than being split between a fitter and a separate sparkie.

As an inland Cockburn suburb close to Bibra Lake and the Beeliar wetlands, South Lake cops the full force of hot, still summer afternoons without a coastal sea breeze to take the edge off. That makes correct sizing important, since an undersized head unit just runs flat out and never quite catches up. The most common requests we see are cooling a master bedroom and open-plan living area together, or replacing a tired old unit that has started leaking or tripping the breaker.

Where homes have been extended or rebuilt as double-storey on the original block, a multi-head system is usually the smarter answer, letting us zone the bedrooms upstairs and living areas below from a single outdoor condenser. Whatever the layout, our air conditioning South Lake installs are planned around tidy pipe runs, neat wall brackets and proper condensate drainage, so the finished job looks as good as it performs.

“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.”
