Split system air conditioning for Mount Nasura homes

Mount Nasura sits on the rising ground of the City of Armadale, an established, well-treed inland suburb tucked against the base of the Darling Scarp. It runs warmer through summer than the coastal suburbs and cools off sharply on winter nights, so most homes here lean on reverse-cycle for both seasons rather than cooling alone. That makes correct sizing the difference between a unit that quietly holds temperature and one that runs flat-out all afternoon - we measure the room, the aspect and the glazing before we recommend a capacity.

The housing is largely original brick-and-tile on generous blocks, much of it built before high-load appliances were standard. We regularly open a switchboard in Mount Nasura and find no spare capacity or an ageing board that needs a dedicated circuit run for the new condenser. Because Otter Air is dual-licensed in both air conditioning and electrical, we handle that switchboard work and circuit in-house in the one visit - no second trade, no second booking. On the sloping and elevated lots common up here, we also plan tidy line runs and proper condenser mounting so the outdoor unit sits level and drains cleanly.

Typical jobs run from a single head cooling a master bedroom or open-plan living area, through to a multi-head system zoning a double-storey home or a larger family house on a bigger foothills block, where longer pipe runs need to be allowed for. Whether you're replacing a tired old unit or fitting air conditioning Mount Nasura homes have never had, we quote the full job up front, including any electrical work.

“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.”
