Split system air conditioning for Gosnells homes

A big share of Gosnells sits on the original 1970s and 80s housing stock: double-brick, tiled-roof family homes with separate living areas and a switchboard that hasn't been touched in decades. When we quote a split system installation Gosnells locals usually want one of two things sorted: cooling the main living and kitchen zone that the whole family ends up crowding into, and getting the master bedroom comfortable for sleeping through a hot inland night. Sitting well back from the coast in the south-east, Gosnells cops the dry, baking summer heat off the Darling Scarp rather than any sea breeze relief, so correctly sizing the unit to the room actually matters here.

The older homes are exactly where being dual-licensed pays off. A tired original switchboard often can't take another high-draw circuit, and a lot of installers have to book a separate sparky and tack the cost on. Because Otter Air is licensed for both air conditioning and electrical, we run the new dedicated circuit, sort the switchboard and mount the head and outdoor unit in the one visit. We're based just up the road in Huntingdale, so air conditioning Gosnells callouts are genuinely local for us.

Newer parts of Gosnells tell a different story. Subdivided blocks and double-storey builds usually suit a multi-head setup, letting us feed several rooms upstairs and down from a single outdoor compressor and keep pipe runs tidy down a brick cavity or external wall. Whether it's a fresh install or swapping out a noisy, end-of-life unit, we'll give honest advice on what genuinely fits your home.
