Below the typical range for this service.
Ducted running cost depends on the system's power draw (not just its size rating), hours run, your electricity tariff, and insulation. Zoning and a good thermostat setting are the biggest levers you control.
💰 Ways to save
- Use zoning to cool or heat only the rooms you are in, the biggest single saving.
- Set the thermostat sensibly, each degree closer to outside temperature cuts running cost noticeably.
- Good insulation and sealing reduce the load, so the system runs less to hold the temperature.
