Split system installation in Mardella

Out on Mardella's semi-rural blocks, a well-placed split system is often the most practical way to cool a sprawling single-level home - and getting the line run and electrical side right matters more here than in a tight suburban lot.

Split system air conditioning for Mardella homes

Mardella sits on Perth's south-eastern rural fringe within the Serpentine-Jarrahdale shire, neighbouring Byford, Oakford, Mundijong and Cardup. It's acreage and rural-residential country rather than dense suburban estate, so the homes here tend to be larger, low-set and spread across big blocks. That layout shapes every split system installation Mardella locals ask us about: rooms are bigger, ceilings are often higher, and the indoor and outdoor units can sit a long way apart. We size the head unit to the actual room volume - not a rule of thumb - so a generously proportioned open-plan living area or master suite actually holds its temperature through a hot inland summer.

Being well inland, Mardella runs hotter and drier than coastal Perth, with no salt-air corrosion to worry about but real demand on a unit through the peak of summer. A common job out here is cooling the master and main living zone first, then adding a second head later, or replacing a tired older unit that's lost its puff. On the larger blocks, the outdoor condenser sometimes needs to sit further from the indoor head than a standard run allows, so we plan longer pipe and cable routes properly rather than forcing a compromise position.

Because we're dual-licensed in both air conditioning and electrical, the wiring side of air conditioning Mardella homes is handled in-house. Older brick-and-tile and rural homes can have switchboards that won't take another load, so we run the new dedicated circuit, fit the isolator and bring the board up to standard without subcontracting it out - one team, one accountable job, start to finish.
