Split System Installation in Ocean Grove

Salt attacks the aluminium fins on an outdoor coil and the fixings that hold the unit up. It reduces heat transfer first, then eats through the fins, and a standard condenser on an exposed Ocean Grove elevation can be visibly powdered within a few years while an identical unit inland looks new.

So we specify a coil with corrosion protection, stainless or hot dip galvanised brackets and sealed enclosures as the baseline here. It is a small proportion of a $2,500 to $7,500 installation and it is the part that decides whether the unit reaches its expected ten to fifteen year life.

About one dwelling in five sat empty on census night, so a meaningful share of homes here are holiday properties. Access has to be arranged rather than assumed, and an owner who lives elsewhere cannot open a door on the morning of the install.

We work around that with a key or code arrangement agreed in advance, a nominated week rather than a same day promise, and photographs of the completed work and the paperwork sent through afterwards. It works well as long as it is planned rather than improvised.

South of Thacker Street the 1887 grid gives regular blocks of 600 to 750 square metres with usable side access, so there is room for more than one condenser and separate systems are on the table. The complication is the protected Moonah and Bellarine Yellow Gum canopy.

Trees are good news for the heat load, because a shaded west wall is a smaller room to condition. They are less good for the outdoor unit, which collects leaf litter in the coil and needs clearance and cleaning it would not need on a bare block.

The newer north east was planned at higher density with minimal side clearance, so the outdoor position question looks like the growth estates rather than the old grid. Often one path, one viable position, and a neighbour wall close enough that placement decides whether anyone complains.

Where the block offers one position, a multi head serving two to five heads is the practical answer. All heads share a compressor, so they cannot run in different modes and part load efficiency is lower, but one well placed outdoor unit beats three badly placed ones.

Installed cost runs $2,500 to $7,500 depending on capacity and head count, with the coastal specification included rather than added later. Reverse cycle heats a room for roughly 28 to 36 cents an hour against 50 to 72 cents for ducted gas. Victorian Energy Upgrades discounts come off the invoice directly, no income test, property at least two years old, $200 including GST minimum contribution, and the program changed on 30 September 2026.

Ocean Grove is about 85km from our Altona workshop, the furthest part of the region we cover. We book work here in planned blocks with a nominated week and no same day attendance, because at that distance anything else is a promise nobody keeps.
