Upgrade existing ducted systems with refrigerated cooling, smart zoning and modern controls — comfort transformed without a full replacement.
Many Sydney homes run ducted heating or ageing ducted systems with a single thermostat and no zoning. An add-on cooling or zoning upgrade reuses your existing ductwork to deliver modern, room-by-room comfort at a fraction of the cost of starting again.
Evercold assesses your ducts, airflow and roof space, then fits motorised dampers, smart zone controllers and — where wanted — app control. The result feels like a new system: even temperatures, quieter running and meaningfully lower bills.
Condition only the rooms in use — zoning typically cuts energy use significantly.
Your existing ducts stay; we upgrade the plant and controls around them.
Schedules, sensors and phone control bring an older system into 2026.
We measure and rebalance every outlet so upgrades actually deliver.
Ducts, plant and airflow assessed honestly — we'll tell you what's worth keeping.
Zoning plan, damper layout and controls matched to how you live.
Dampers, controller and any new plant fitted cleanly in a day or two.
Airflow tuned and every zone verified to temperature.
Often, yes — if the ductwork is sound and sized adequately. We assess duct condition, insulation and fan capacity first, and give you a straight answer before quoting.
It depends on the number of zones and access, but retrofitting dampers and a smart controller is a fraction of a full system replacement. We quote fixed, after a site inspection.
Modern zone controllers are largely brand-agnostic. We regularly integrate with Daikin, ActronAir, Brivis and similar plants.
Most zoning retrofits are completed from the roof space in one to two days with no wall or ceiling damage.
Yes — we offer app-connected controllers with schedules, room sensors and energy insights.
