Which is better, split or ducted air conditioning?

Splits are cheaper and let you cool rooms independently. Ducted systems distribute air more evenly, hide inside the false ceiling and allow per-room zoning; in exchange they require enough false-ceiling depth and a higher initial investment.

Can a heat pump replace a gas boiler?

In a well-insulated home, yes: the aerothermal pump produces domestic hot water and backs up heating more efficiently than a traditional gas boiler. In poorly insulated homes, the boiler is still competitive on peak demand.

Thermal comfort and air conditioning

Residential climate control in Málaga and the Costa del Sol

Climate control resolves thermal comfort for the home: split or ducted air conditioning, heat pump for domestic hot water and underfloor heating. We work alongside the authorised fluorinated-gas installer for the equipment commissioning.

What it involves

In the Costa del Sol, air conditioning is no longer optional from June to September, and the heat pump is gradually displacing traditional heating. Two different problems — cold and heat — now solved by increasingly integrated equipment.

The main decision is where to place the outdoor unit (façade, patio, roof), where to route the refrigerant lines and condensate drain, and which indoor units fit the existing layout best. For the gas charge and commissioning we work with installers holding the fluorinated-gas qualification (RITE and RD 115/2017), as the regulation requires that specific authorisation.

01 Approach

More than a split on the wall

Modern climate control goes beyond the traditional wall split: an aerothermal heat pump produces domestic hot water and heating at high efficiency; ducted systems distribute cold and hot air evenly across the home. The choice depends on the type of property, intended use and available budget.

Typical scope

What this service includes

We install the most common climate systems in residential properties and coordinate the required building work.

ac_unit

Split and multi-split

Individual units per room (one outdoor + several indoor). Standard in flats and partial renovations, with refrigerant line routed along façade or wall.

air

Ducted system in false ceiling

Single unit per floor with ducts hidden in a plasterboard false ceiling. Even distribution, invisible finish and linear grilles.

heat_pump

Aerothermal heat pump

Aerothermal equipment to produce domestic hot water and back up heating. An efficient alternative to the traditional gas boiler.

thermostat

Reversible underfloor heating

Hydraulic underfloor system with independent circuits per room and a general manifold. Compatible with heat pump.

filter_alt

Ventilation and filtering

Air renewal with enthalpy recovery in well-insulated homes and appropriate filters in areas with pollen or urban dust.

settings_remote

Control and zoning

Per-room thermostats, app control and ducted zoning to operate only the spaces in use.

Climatised zones

Per-room zoning and usage profile

Zoned climate control lets temperature and schedules match the real use of each room, saving energy and reducing noise where it is not needed.

king_bed Bedrooms

Quiet units with adaptable airflow, night-time scheduling and individual control.

weekend Living room

Higher cooling capacity due to larger volume and occupancy; adjustable louvre for even reach.

kitchen Kitchen

Climate control complementary to the hood ventilation; specific equipment with grease filter when relevant.

soap Wet areas

Air treatment in dressing rooms and bathrooms with supply duct and return grille.

garage Penthouses and ground floors

Specific solutions for floors more exposed to radiation or humidity by level.

Ducted climate control

Comfort you feel, equipment you forget

Indoor units, ducts and grilles sit in the false ceiling, calibrated by thermal load per room. Only the diffusers remain visible when the project is handed over.

Worth knowing

Before deciding the scope

Climate control has specific technical and regulatory constraints to review before quoting.

badge

Authorised installer

Handling fluorinated gases requires professional authorisation. We coordinate the works with authorised installers; we do not perform that part without that authorisation.

gavel

Façade and building management

Outdoor units on the façade usually require building management approval. In some municipalities and protected developments they are limited to internal patios.

water_drop

Condensate drain

Every indoor unit generates condensate in cooling mode. The drain network needs the right fall and to connect to a suitable outlet.

bolt

Dedicated electrical circuit

Heat pumps and ducted equipment need their own electrical circuit with the right protection, planned from the electrical installation stage.

Installation sequence

Phased installation, from thermal load to commissioning

Climate control is designed before being installed: correct sizing avoids oversized noisy equipment or undersized inefficient equipment.

Equipment selection

Choice between split, multi-split, hidden ducts or aerothermal based on layout, surface area and budget.

Commissioning

Gas charge where applicable, tightness test, airflow verification and system start-up.

Documentation

Installation certificate, user manual and preventive maintenance plan delivered.

Outdoor unit

Where the heat is actually exchanged

The outdoor unit is placed on vibration-damping brackets, with insulated copper piping and an unobstructed clearance for air flow. Correct siting is what keeps the system quiet and efficient.

Planning

Checklist before contracting climate control

Five decisions that drive equipment, installation and final comfort.

01
straighten Duct routing

If opting for ducted systems, decide routes before closing the plaster, with supply- and return-grille orientation.
02
bolt Electrical power

Confirm the panel can host the dedicated outdoor-unit circuit, with the correct breaker and free slot.
03
water_drop Condensate drainage

Direction and slope of the condensate pipe to stack or shaft — avoids drips and ceiling stains.
04
ac_unit Outdoor unit location

Internal patio, roof or façade with community approval; distance from the bedroom to minimise noise.
05
smart_display Control system

Individual thermostats, app control or home-automation integration — decided before pulling control wiring.

In depth

Residential climate control in Málaga: air conditioning, aerothermal and underfloor heating

Climate control on the Costa del Sol combines long summers with heat peaks and high radiation, mild winters with cool nights inland and high relative humidity in coastal areas. Correct equipment sizing requires a load calculation per room taking into account orientation, surface area, insulation and expected occupancy. An oversized split cycles in short bursts, consumes more and makes more noise; an undersized one never reaches the set temperature.

In new builds or complete renovations we work with aerothermal units (air-to-water heat pump with outdoor unit and buffer tank) for heating, cooling and domestic hot water from a single machine, paired with reversible underfloor heating or low-temperature radiators. In partial renovations the usual approach is air-based: wall split, multi-split (one outdoor, several indoor) or hidden ducts in false ceiling with linear grilles. The choice depends on the allowable scope of works and the finish required.
