Split system air conditioning for Willetton homes
Willetton is a settled inland suburb in Perth's south-east, part of the City of Canning and bordered by suburbs like Leeming, Bull Creek, Riverton and Rossmoyne, with the Canning River corridor not far to the north. Being well away from the coast, salt-air corrosion isn't a worry here, so the focus is on getting the right capacity into homes that bake through the long, dry inland summers and hold heat well into the evening.
Much of the original housing stock is generously sized 1970s and 80s brick-and-tile on large blocks. These homes often run older switchboards that simply weren't designed for an extra air conditioning load, so a new dedicated circuit is usually part of the job. Because Otter Air is dual-licensed in both air conditioning and electrical, we do that switchboard and circuit work in-house - no waiting on a separate sparky and no finger-pointing if something needs sorting. A common Willetton brief is cooling a master bedroom plus the main open living zone with a well-placed wall split.
The suburb also has its share of renovated and double-storey rebuilds, and these suit a multi-head setup - one outdoor unit feeding indoor heads upstairs and down, with line runs concealed neatly through the roof space or cavities. We just as often handle changeovers, swapping a tired, noisy old unit for a quiet, energy-efficient inverter model. Whatever the scenario, air conditioning Willetton work gets the same tidy, compliant approach from licensed local technicians.
