Straight answer: a single-split for one room is installed from about €550 (9,000 BTU), while a whole-home multi-split runs roughly €1,500–4,500 depending on the number of rooms. These are installed prices — equipment plus fitting by an F-gas certified technician — and Lisbon and Cascais sit at the higher end.

Just moved to Portugal and getting three wildly different numbers? You're not imagining it. Most installers hide the price behind "request a quote", so newcomers can't tell a fair figure from a padded one. Here's the honest version, up front. For one room, budget €550–1,000 for a single-split, sized to the room. For a whole apartment or house, a multi-split lands between €1,500 and €4,500 for most T1–T3 homes, and higher for larger properties. Everything you see here is the finished, installed price — the same numbers on our AC Installation Lisbon homepage — not equipment-only "from" pricing that balloons once the fitter arrives.
The honest rule of thumb: for one or two rooms, separate single-splits are usually the cheapest way in. From three or four rooms up, a multi-split — several indoor units sharing one outdoor unit — often works out better value overall: one outdoor unit instead of four, a tidier façade, and less labour per room.

Annual maintenance (clean + gas check): ~€60–180 per unit. Prices are indicative guide ranges, not a quote.
Each extra indoor unit adds equipment and labour — this is the single biggest driver.
Beyond the standard ~3 m, extra copper piping is charged per metre.
Your own balcony is cheap; a high façade needing scaffolding or a shared roof costs more.
Daikin/Mitsubishi sit at the top; Gree/Haier are more affordable for the same room.
If piping and holes already exist, installation can be 30–50% cheaper.
In Alfama, Baixa & Chiado, outdoor units on the façade may be restricted.
A low headline number that isn't certified work is the most expensive AC you can buy: in Portugal, air conditioning must legally be installed by an F-gas (gases fluorados) technician. An uncertified job risks fines, leaks and a voided manufacturer warranty. Our ranges bundle the parts that actually protect you — read the full process on our installation guide.

A little. Central Lisbon apartments and Cascais villas often mean longer pipe runs and trickier façade access, so they sit at the higher end; Almada, Setúbal and newer builds can come in lower. We cover all of it.
If you rent, live in a protected historic building where an outdoor unit isn't allowed, or only need cooling for the summer, paying €550+ to install may not add up. Our sister company AC Rental Lisbon delivers portable air conditioning across Lisbon — same-day, no installation, no drilling — often the cheaper route for tenants.
As a guide, a single-split for one room is installed from about €550 (9,000 BTU), €700 (12,000 BTU) or €1,000 (18,000 BTU). A whole-home multi-split runs roughly €1,500–4,500 depending on how many rooms you cool. Lisbon and Cascais tend to sit at the higher end. The figures are installed prices — equipment plus fitting by an F-gas certified installer. Your exact number depends on your building, which is what the free quote is for.
Both. The ranges we publish are installed prices: they include the unit itself and the labour of the certified technician, using the standard run of copper piping. Your written quote itemises everything so there are no surprises at the end. Genuinely extra items — long pipe runs or scaffolding — are listed separately and up front.
Two reasons. First, the buildings: older Lisbon apartments and Cascais villas often mean longer pipe runs, awkward façade access or condominium rules that push up labour. Second, demand is high in these areas. That's why we quote the higher end of each range for central Lisbon and the coast, and confirm the exact figure once we understand your specific flat.
A single-split 9,000 BTU unit, installed from about €550, is the best-value fixed option for one bedroom or study up to roughly 25 m². If you rent, live in a protected historic building, or only need cooling for a few weeks, a fixed install may not be worth it — a portable rental from our sister company AC Rental Lisbon is often cheaper and needs no drilling.
For most owners, yes. A modern split is a heat pump: it cools in summer and heats in winter with about three times less electricity than an electric heater, so it replaces both a fan and a winter heater and cuts your heating bill. It also tends to make an apartment more comfortable and easier to rent or sell. For tenants the maths is different — renting a portable unit usually makes more sense.
The main extras are: copper piping beyond the standard ~3 m (charged per metre), scaffolding or rope access where the outdoor unit sits on a high façade, and occasionally a wall bracket or condensate pump. Ongoing, budget roughly €60–180 per unit per year for a clean and gas check to keep it efficient and under warranty. Everything appears on your quote before you commit.
