Split System Installation in Newport

Newport period blocks generally have a driveway or path down one boundary and a real rear yard. That sounds mundane until you compare it with Footscray or Yarraville, where a single rear condenser position dictates the whole design.

Here we can usually place two or three outdoor units with proper airflow clearance and service access, which keeps single head systems on the table. Singles are more efficient at part load, they let rooms run at different temperatures and in different modes, and one failure does not take out the whole house. Where the space exists, that is the better system, and in Newport the space usually exists.

Weatherboard and early brick construction with little or no wall insulation is the norm in this stock. Ceilings are typically 2.7 to 3.0 metres in the older homes, which adds volume over a post war house, and the ceiling insulation is usually either original, compressed, or missing above a later extension.

That is where we start. Restoring ceiling insulation in a Newport period home is the cheapest capacity available and it regularly drops a living room from 7.1kW to 5.0kW. We check the roof space before quoting a number, because sizing a system for a house you intend to insulate is a different calculation from sizing it for the house as it stands.

Newport is close enough to the water that salt reaches outdoor gear. It is milder than Seaholme or the Altona foreshore, but it is enough that plated brackets and standard coils age faster here than they do in Sunshine or Braybrook.

Our standard is a condenser with corrosion protection on the coil and stainless or galvanised mounting hardware, positioned where the building offers some shelter from the prevailing weather. A fresh water rinse of the outdoor coil each spring costs nothing and adds years to it. Mature street trees also matter here, less for shading the unit than for the leaf litter that blocks a condenser coil over an autumn.

Each indoor head needs a dedicated circuit and an isolator. In a Newport home with an original board, that is the moment to replace the board rather than squeeze in one more circuit, because residual current protection across the whole house is worth far more than the incremental cost while an electrician is already on site.

On the money, a split system is $2,500 to $7,500 installed depending on capacity and head count. Victorian Energy Upgrades discounts come off the invoice directly, with no income test, on properties at least two years old, with a $200 including GST minimum customer contribution. Announced changes commence 30 September 2026 and amounts are confirmed in writing at quote. Refrigerant work is under ARC licence and the electrical connection under REC 37223.

Running cost is where the case is made. Reverse cycle returns 3 to 4 units of heat per unit of electricity while gas converts only 80 to 92 percent of its fuel, so heating a room costs roughly 28 to 36 cents an hour instead of 50 to 72 cents for ducted gas. For most Newport households that is $200 to $450 a year, and more again if the gas supply charge goes with it.
