Choosing the right system for Ultimo
The right ducted air conditioning setup for a Ultimo property depends on the building first and the brand second. Free on-site assessment and system sizing, usually within 24–48 hours
Our technicians work across the Inner City every week, so the recommendation you get is grounded in what actually performs in local homes like yours — not what's sitting in a warehouse. Every quote is free, on-site and fixed in writing.
What affects the price in Ultimo
- Every Ultimo home is different, so honest ducted air conditioning pricing has to account for your specific job: home size and ceiling height, insulation and glazing, how many zones or rooms you want conditioned, and the installation access at your property.
- The price ranges above reflect real completed jobs across the Inner City. Your free on-site quote converts them into a single fixed written price for your home — valid for 30 days, no obligation.
Local conditions in the Inner City
- Most inner-city homes were built long before ducted air conditioning existed, so retrofitting takes careful design — slim-line units, creative duct routing and quiet outdoor placement. Body-corporate approval is part of nearly every apartment job, and we handle that paperwork as standard.
- Summer humidity rolling in off the harbour means dehumidification matters as much as raw cooling here. Correctly sized inverter systems handle both; oversized ones do neither well.
