Split System Installation in Armstrong Creek

On a lot this width, a condenser in the side path is a running compressor a couple of metres from a neighbour bedroom window. It is the single most common reason we move a proposed position, and it is far easier to solve before installation than after a complaint.

The practical rules are simple. Keep the unit away from bedroom windows on both sides, avoid boundary corners where two hard surfaces reflect sound back out, and mount it so no vibration is carried into the frame. Inverter condensers run around 50 to 60 decibels at a metre, which is fine at a distance and noticeable at two.

There is no subfloor here, so new circuits and pipe routes go through the roof space and down inside a wall cavity. On a new truss roof that is straightforward work, but it does limit where a run can drop down, because a truss layout and a slab together leave fewer options than an older house on stumps.

We plan the route at the quote. A head on an internal wall may need a longer run and a condensate pump where gravity fall is not available, an indicative $250 to $500. Knowing that before the equipment is chosen is what keeps the price stable.

Modern insulation genuinely reduces the heat load, so an Armstrong Creek bedroom often takes 2.5kW where a Corio bedroom the same size wants 3.5kW. The offsetting factor is glass. Estate homes have large window and sliding door areas, often single glazed, and tight setbacks mean neighbouring houses provide no shading.

Geelong is drier than Melbourne, sitting in the Otway rain shadow, and summer heat here comes with strong sun and little cloud. A west facing living area with a large slider is the room that decides the system, and it is regularly a size larger than the floor plan implies.

Where the side path holds one condenser and the rear yard is small, a multi head serving two to five heads keeps the outdoor footprint to one unit and one set of clearances. On these lot widths it is frequently the sensible answer.

Where the rear yard has room behind the garage, separate single head systems are worth the second outdoor unit. They run at their best efficiency in each room, and a fault takes out one room rather than every conditioned space in the house.

This matters more in Armstrong Creek than anywhere else in the region. Victorian Energy Upgrades requires the property to be at least two years old, so a house handed over last year does not qualify, no matter how efficient the equipment is. On older parts of the estate the discount applies, comes off the invoice directly, has no income test and carries a $200 including GST minimum contribution. The program changed on 30 September 2026.

Installed cost runs $2,500 to $7,500 depending on capacity and head count. Armstrong Creek is about 70km from our Altona workshop, so we book work here in planned blocks and give you a nominated week rather than an hour.
