Split system air conditioning for Armadale homes
Armadale's housing is a real mix, and that's what shapes a split install here. There are plenty of established brick-and-tile homes from the 1970s and 80s on generous blocks, alongside the newer double-storey estates that have spread out toward the foothills and the southern fringe in recent years. The older homes often have separate, closed-off rooms - so a single head in the master and another in the living area usually does the job better than one oversized unit trying to push air around walls. We size each head to the room rather than overselling, which keeps your running costs down through a long inland summer.
The newer two-storey builds are a different story. Heat rises, and upstairs bedrooms can sit several degrees warmer than the ground floor, so we're often planning condenser positions and routing refrigerant lines up an external wall or through a roof space to reach those rooms cleanly. For big open-plan living-and-kitchen zones, a larger single head or a multi-head setup tends to make the most sense. Either way, we plan tidy line runs so the finished job looks neat, not like an afterthought stuck on the brickwork.
One thing that genuinely matters in Armadale's older homes: the switchboard. A lot of them weren't built with high-draw appliances in mind, and a new split system frequently needs its own dedicated circuit. Because Otter Air is dual-licensed for both air conditioning and electrical, we handle the wiring, the circuit and any switchboard upgrade in-house on the same visit - no waiting on a separate sparky. That's a big part of why people choose us for air conditioning Armadale: one team, one quote, one accountable job from the wall bracket to the breaker.
