We fit split and multi-split systems in villas and apartments across Cascais, Estoril, Carcavelos and the whole Linha — by F-gas certified installers, with a VAT invoice and written warranty. One system cools in summer and heats in winter. Free, itemised quote within 24 hours.
Brought to you by the local team behind AC Rental Lisbon — years of keeping Lisbon homes and apartments comfortable.
Cascais and Estoril bring their own quirks — salt air, big villas and strict condomínios. Here's what we plan for before we quote.
From Guincho to Estoril and Carcavelos, salt corrodes poorly-protected outdoor units. We advise sheltered placement and, where it's worth it, units with anti-corrosion treatment so they last by the sea.
For a moradia we usually plan a multi-split: several indoor units on one outdoor condenser, with copper pipework run discreetly between floors. We map the route and the outdoor spot first, so there are no surprises.
In apartment blocks, placing the outdoor unit on the façade can need condomínio approval. We help find a compliant spot — balcony, light well or technical zone — and flag it before any work.
You don't lift a finger beyond the form. We size it, quote it honestly, and handle the certified install end to end.
Area, number of rooms and your building type — about a minute in the form. That's all we need to start.
We work out the right system for your place and send it, itemised, within one working day.
A vetted F-gas certified installer fits it cleanly — a single-split in a few hours, a multi-split over one to two days.
You're fully covered, warranty in writing. Need a service or another room later? We're a message away.

As a guide, a single-split for one room is installed from about €550 (9,000 BTU) up to €1,000 (18,000 BTU); a whole-home multi-split runs roughly €1,500–4,500 depending on the number of rooms. Cascais and Estoril tend to sit at the higher end. Your exact price depends on the property — that's what the free quote is for.
Yes. In villas we usually plan a multi-split — several indoor units connected to one outdoor unit, with the copper pipework run discreetly between floors. We assess the route and the outdoor-unit location before quoting so there are no surprises on the day.
Near the sea — Guincho, Estoril, Carcavelos — salt air corrodes poorly-protected units. We recommend sheltered placement and, where it makes sense, equipment with anti-corrosion treatment to extend the machine's life close to the coast.
In apartment blocks, mounting the outdoor unit on the façade can require condomínio approval. We help find a compliant location — balcony, light well or technical area — and if a fixed unit isn't possible we point you to the portable rental alternative.
Yes. In Portugal, air conditioning must be installed by an F-gas (gases fluorados) certified technician. Every install is carried out by a certified, insured installer who issues a factura c/IVA and provides the workmanship warranty.
We send the quote within 24 hours. Once you confirm, we book the install: a single-split is usually fitted in a few hours and a whole-home multi-split can take one to two days. We confirm dates in the quote.
