Instalación de aire acondicionado en Benalmádena

Installing air conditioning on the Costa del Sol carries a demand you won't find inland: salt-laden air. On the front line between Marbella and Estepona, outdoor units without anti-corrosion treatment lose years of service life, which is why we fit coils protected with Blue Fin or Gold Fin coatings. The equipment also works the opposite way to northern Spain: it cools through a long summer and heats a mild winter, where a heat pump delivers an exceptionally high SCOP. We install split, multisplit, ducted systems hidden in false ceilings and aerothermal units, always sizing capacity to the home's real orientation, glazing and insulation. When the system is built into a renovation, the pre-installation is resolved before ceilings and walls are closed, with no later mess or surprises.

Split, multisplit, ducted or aerothermal: which system fits

A 1x1 split conditions a single room; for three or four bedrooms a multisplit (one outdoor unit feeding several indoor heads) is usually smarter than covering the facade with machines. If the renovation includes a false ceiling, ducted systems are the most elegant choice: only the grilles are visible and air distribution is even and quiet. Aerothermal technology goes further, covering climate control, underfloor heating and domestic hot water from a single heat pump. We size by thermal load, not floor area: the old rule of 100 frigorías/m² falls short against large south-facing windows. We work with Daikin, Mitsubishi Electric, Fujitsu and Panasonic, prioritising inverter ranges and anti-corrosion protection on the coastline.

How we install, step by step

We start by setting out the run of the refrigerant line (insulated copper pipe) and the condensate drain, with a continuous fall to prevent drips and damp. In a renovation, that pre-installation is embedded before ceilings and partitions are closed. We fix the outdoor unit on brackets with anti-vibration mounts, pull a vacuum with a pump and run a nitrogen pressure test before releasing the gas: skipping this step is the industry's most common mistake and ends up wrecking the compressor. We wire a dedicated protected electrical circuit, charge or verify the refrigerant, and commission the system measuring pressures and temperature split. A simple split is done in a day; a ducted system takes two or three, coordinated with the false ceiling.

Efficiency, refrigerant and soundproofing

The energy label no longer talks about raw frigorías but about SEER (cooling) and SCOP (heating): the higher they are, the less the unit consumes across a full season. Inverter technology modulates the compressor instead of switching on and off, and it is the difference between a controlled bill and a runaway one during an Andalusian summer. On refrigerant, R-32 (GWP 675) is still the standard, but the new European F-gas rules (EU Regulation 2024/573) are pushing towards R-290 (propane, GWP 3) in small units by 2027-2029. For a restful home, we set indoor units to night mode and mount outdoor units on silent blocks, away from bedrooms and the neighbour's party wall, also managing fan orientation.

Regulations, permits and warranty

Installing air conditioning with fluorinated gas is not unregulated work: Spain's RD 115/2017 requires an RITE-authorised company and technicians holding the fluorinated-gas handling certificate. Buying the unit online and installing it without accreditation leaves the job with no compliance certificate and voids the manufacturer's warranty. On the Costa del Sol there is an extra step: placing the outdoor unit on the facade, courtyard or roof of a shared building usually needs the community of owners' authorisation, and some urbanisations demand specific locations or screening. We check and arrange this before drilling. Our own in-house team, never subcontracted, signs off the installation, leaves the paperwork in order and backs it with a 5-year guarantee, beyond the equipment's own.
