Split system air conditioning for Forrestdale homes

Forrestdale is one of those suburbs with two very different faces, and that shapes how we approach a split install. Across the older, rural-residential part of the suburb you'll find larger lots with the home set well back from the street and outbuildings dotted around. On blocks like these the practical challenge is usually distance: getting refrigerant lines and the condensate run from an indoor head to a sensibly placed outdoor unit can mean a longer pipe run than a standard suburban job. As a dual-licensed air conditioning and electrical contractor, we can also run a new dedicated circuit back to the switchboard ourselves rather than leaving you to chase a separate sparky.

Closer to the Harrisdale and Piara Waters boundary, Forrestdale's newer estate homes tend to be double-storey on tighter lots. Here the common request is a multi-head split system - one outdoor unit feeding a head in the upstairs main bedroom and another in the open-plan living below - which keeps the wall footprint tidy and avoids cluttering a small alfresco with multiple condensers. We plan head placement and the riser route up front so the install is neat and the running costs stay sensible.

Being well inland and away from the coast, Forrestdale homes cop genuinely hot, dry summer days, so most owners want refrigerated cooling that actually copes when it counts - whether that's a single room, a master-plus-living combo, or replacing a tired old unit that no longer keeps up. Older brick-and-tile homes sometimes have an original switchboard that needs attention before a new circuit goes in, and because we hold both tickets, that's handled in-house. If you're weighing up air conditioning Forrestdale options, we'll size the system to the room and the orientation, not just sell you the biggest box.
