Marbella · Since 2000 · Daikin Authorised Partner

HVAC specialists.
Marbella, since 2000.

We're a small, specialist team covering air conditioning, heating, heat pumps, water treatment, ventilation, and pools across the Costa del Sol. Not a franchise, not a generalist contractor — a company that does one thing properly.

Our Story

Built on technical expertise and a long memory

Oasis Energy Solutions has been operating on the Costa del Sol since 2000. Over 26 years we've worked across residential, commercial, and industrial projects — from single-room split installations to full M&E packages for new-build villas.

We're based in San Pedro de Alcántara and cover Marbella, Estepona, Benahavís, Fuengirola, Mijas, and the wider Costa del Sol. The bulk of our work comes from repeat clients and referrals — which, after 26 years, says something about how we operate.

We don't take on everything. We focus on the areas where we have genuine depth: HVAC design and installation, heat pump systems, pool heating, water treatment, and ventilation. We don't do solar. We don't do general electrical. We do what we're good at.

Credentials

Authorised by the brands we install

These aren't self-declared — they're manufacturer authorisations that require training, standards compliance, and ongoing certification.

Daikin Authorised Partner

One of approximately three Daikin Authorised Partners in the Marbella area, and around nine on the Costa del Sol. Factory-trained on VRV, ducted systems, Altherma heat pumps, and the full Daikin range. Full manufacturer warranty on every Daikin installation we carry out.

Mitsubishi Electric Approved Installer

Approved Installer status for Mitsubishi Electric systems — including City Multi VRF, ducted units, and the full split and multi-split range. Qualified to design, install, and commission Mitsubishi Electric systems to factory specification.

Airzone Elite Installer

Elite Installer status for Airzone zone control systems. We design and install Airzone Flexa (ducted AC zoning) and Airzone Acuazone (heating and DHW) — giving clients independent temperature control in every room from a single system.

How We Work

What you can expect

1

We visit before we quote

We don't price from a floor plan or a phone call. We visit the property, assess the space, and design the right system — then give you a fixed written price that covers everything.

2

Our own technicians, always

Every installation is carried out by our own qualified team. We don't subcontract. The technicians who install your system are available for maintenance and repairs throughout its life.

3

No surprises on completion

The price we quote is the price you pay. We handle all documentation: installation certificate, F-Gas records, and manufacturer warranty registration. Everything in order from day one.

4

Bilingual — English and Spanish

We work in both languages across the full project lifecycle — quoting, installation, documentation, and ongoing support. No translation layer required.

👆 Option A — Team photo, no individual names

Clean and professional. Shows the team as a unit. No commitment to keep individual bios current.

Alex Rittener — Owner, Oasis Energy Solutions

Alex Rittener

Owner & General Manager

I founded Oasis in 2000, having moved to the Costa del Sol from the UK. The original focus was commercial M&E — fit-outs, new builds, industrial projects. Over time the residential market grew significantly, and today it's the core of what we do, alongside ongoing commercial and new-build work.

I'm directly involved in every project at the quoting and design stage. My job is to make sure we specify the right system, price it properly, and deliver what we said we would.

Oasis team

Our field team of qualified HVAC engineers carries out all installations and maintenance work across the Costa del Sol. We don't subcontract — everyone who works on your project is part of the Oasis team.
