How much does a ducted AC system with Airzone smart control cost in Benalmádena?

Request a property-specific written quotation. Equipment, access, cable routes, protection, documentation and any remedial work determine the scope. A case study is not a fixed-price offer or a guarantee of savings; financial comparisons require your demand, tariff and realistic operating assumptions.

How long does ducted AC installation take for an apartment?

The schedule is agreed after surveying the property. Access, construction work, equipment availability, testing and any distributor or authority requirements can affect completion. Do not assume that another project's duration will apply to your installation.

What electrical and refrigerant certificates are provided for AC installation?

All AC installations include: a Certificado de Instalación Frigorífica documenting refrigerant type and charge weight, a Boletín Eléctrico covering all electrical works, and a manufacturer's commissioning report.

How does Airzone zoning save energy compared to standard AC?

Standard ducted AC cools or heats the entire property to a single setpoint — even empty rooms. Airzone adds motorised dampers to each zone's ductwork and smart thermostats in each room, so the system only conditions occupied spaces. In a 4-bedroom apartment where 2 bedrooms are typically unoccupied during the day, this delivers 35–45% energy savings versus a standard single-zone ducted system.

The Challenge

This 4-bedroom Benalmádena apartment on the Costa del Sol had no air conditioning at all — the previous owner had relied on natural ventilation and ceiling fans. Spanish summers in Benalmádena reach 35–38°C for 8–10 weeks, making the apartment genuinely uncomfortable and reducing lettings potential during peak season. The client needed a multi-zone climate control solution that could be installed cleanly in an apartment with a non-negotiable aesthetic — no visible external pipework, no surface-mounted ductwork, and a controller interface compatible with the property's existing smart home system.

The Solution

Multi-zone air conditioning with Airzone smart control for 4-bedroom apartment. Individual room temperature control.

Technical Specifications

Ducted AC system with 6 zones
Airzone smart dampers and controls
Individual room thermostats
Mobile app control
Energy monitoring system

Our Installation Process

Apartment Survey & Cooling Load Calculation

We surveyed all rooms for ceiling height, window area, and solar exposure to calculate individual zone cooling loads. The south-facing living room (28m²) presented the highest cooling demand at 4.2kW at peak summer conditions. Total building cooling load: 9.8kW across 4 zones. We specified 4 independent ceiling cassette units to allow individual zone control without overcooling unoccupied bedrooms.

Cable & Pipework Routing Plan

All refrigerant pipework and electrical cables were routed through the building's existing ceiling voids, accessed by temporarily removing sections of the suspended ceiling. External condensing units were positioned on the apartment's private south-facing terrace, connected through a single 80mm core-drilled penetration per unit — each sealed with fireproof acoustic compound and finished with a paintable grille externally.

Airzone Smart Controller Integration

Each cassette unit was fitted with a concealed Airzone thermostat in the ceiling. The Airzone central controller provides both individual room temperature control and integration with Alexa and Google Home. The system was also configured for the existing KNX smart home bus, allowing zone temperatures to be part of the apartment's existing automation scenarios — including a 'holiday mode' that sets all zones to 28°C protection mode when unoccupied.

Testing, Balancing & Handover

Each zone was tested for airflow balance, temperature differential, and noise levels. The system was set to maximum cooling with doors closed to verify no temperature bleed between zones. Commissioning data — pressures, superheat, subcooling — was recorded for warranty records. The client was trained on the Airzone app and received the REBT Boletín Eléctrico, refrigerant installation certificate, and Mitsubishi warranty registration.

Assess airflow, capacity and compatible controls

Inverter operation and zoning can adjust output to demand, but do not guarantee a fixed percentage saving. Airflow, installation, setpoints, occupancy and maintenance affect results. Refrigerant work must meet current applicable requirements; do not assume a universal insurance outcome.
