A ducted air conditioning system hides the indoor unit in the ceiling void and feeds cooled air through a network of insulated ducts to grilles in each room. From the floor below, all that is visible is a low-profile vent. Most British and European owners building or refurbishing a villa on the Costa del Sol pick ducted for the same reason: the rooms feel cooler and quieter, the ceilings stay clean, and the controller manages the whole house from one place rather than a remote in every bedroom.
How a ducted system differs from wall splits
A wall split is one indoor unit serving one room. A ducted system is one large indoor unit serving multiple rooms through ductwork. The outdoor condenser is similar in both cases, but the ducted indoor unit is a high-static fan-coil mounted out of sight, with rectangular grilles in the ceiling rather than a plastic head on the wall. For a four-bedroom villa, a ducted install replaces what would otherwise be four or five separate wall splits, four or five remotes and a row of outdoor units on the side wall.
Where ducted fits, and where it does not
Ducted suits properties where the false-ceiling allowance is built in or can be added during refurbishment. Newer villas on the New Golden Mile, in Sotogrande and across the Marbella urbanisations are usually designed around a ducted system from day one. Older townhouses in Mijas Pueblo or Fuengirola with concrete soffits and no service void are far harder, and a multi-split is normally the better answer there. Apartments rarely take ducted because there is no floor or roof above to run pipework into. Where a property does suit ducted, the install gives the cleanest finish of any AC type, with no plastic units on the walls and no remote on the bedside table.
Zoning is what makes the running cost work
Without zoning, a ducted system cools every room whether it is occupied or not. With zoning (motorised dampers in the ductwork plus a thermostat in each room) the system only cools what the household is actually using. An empty guest wing through January takes no energy. A north-facing study at the back of the house can run cooler than the south-facing lounge. Spanish-built Airzone is the controller we fit most often because the integration with Toshiba, Fujitsu, Mitsubishi and Panasonic is solid and the wall thermostats are clearly labelled in English or Spanish to suit the household.
What an EnviroCare ducted install includes
A typical install takes three to five working days for a four-bedroom villa, depending on the ductwork run lengths and whether new electrical capacity is needed at the consumer unit. The work covers the indoor fan-coil unit, insulated rigid or flexible ductwork sized to the airflow, ceiling diffuser grilles in each room, the return-air grille, the outdoor unit on anti-vibration mounts, the refrigerant pipework brazed and pressure-tested under vacuum, the condensate drain to an external soakaway or waste pipe, the electrical circuit with RCD certified by a registered electrician, the Airzone controller and per-room thermostats, full commissioning and the F-Gas paperwork on file. We protect floors and finishes through the build, snag the ceiling line at handover and walk through the controls room by room.
What it costs to run
A correctly sized ducted system with zoning runs at lower cost than the equivalent set of wall splits because the household only conditions the rooms in use. The single biggest driver is whether the property is held cool overnight or set to come on at 2pm when the sun hits the south wall. Most owners settle on a schedule of cooling in the bedrooms from late evening to early morning and the lounge from mid-afternoon, which keeps the unit working in cycles rather than fighting a hot house from a cold start.
