Looking to install AC in a Lisbon flat? We fit split and multi-split systems across the whole city — from the historic centre of Alfama, Baixa and Chiado to modern Parque das Nações — by F-gas certified installers, with a VAT invoice and written warranty. In protected streets we plan the outdoor unit to fit the rules. One system cools in summer and heats through the damp 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.
A Lisbon install is rarely a house with a garden — it's a flat, often in an old building, often with condomínio rules. Here's what we plan for before we quote.
In Alfama, the Baixa Pombalina, Chiado and Graça, mounting the outdoor unit on the façade can be restricted by the condomínio or the council. We plan discreet, compliant placement — a light well, terrace or technical zone — and flag it before any work.
Most Lisbon homes are flats, so the real question is where the outdoor unit goes: balcony, marquise, light well or a well-fixed bracket. Where façade space is tight, a multi-split puts one unit outside for the whole home instead of one per room.
Lisbon flats rarely have central heating and feel cold and damp from December to March. A heat pump cools in summer and heats in winter with about three times less electricity than a plug-in heater — comfort all year from one system.
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. In the historic centre, façade access and pipe runs can push it to the higher end. Your exact price depends on your building — that's what the free quote is for.
Usually yes, but with care. In protected zones, putting the outdoor unit on the façade can be restricted by the condomínio or council rules. We assess the building and advise a compliant placement — light well, courtyard, roof or technical area — that respects the rules and the façade. If a fixed unit truly isn't allowed, we point you to the portable alternative.
Common in central Lisbon. We work through the options building by building: internal light well, marquise, common roof, a discreet side wall or a well-fixed bracket, with the copper pipework kept short and tidy. If there's genuinely no viable spot, we tell you honestly.
Inside your flat, no. For the outdoor unit on the façade or common areas, many Lisbon buildings require condomínio approval, and classified zones can have council rules. We help you understand what applies to your building and choose placement that avoids trouble later.
Yes. Every split we fit is a heat pump: it cools in summer and heats in winter with about three times less electricity than an electric heater. In a Lisbon flat with no central heating, that's proper, affordable winter warmth — and it helps with the damp.
Yes. In Portugal, AC must be installed by an F-gas (gases fluorados) certified technician. Every install is done by a certified, insured professional who issues a factura c/IVA and gives the workmanship warranty.
