A multi-split runs several indoor units from a single outdoor condenser — so you climate the whole flat while keeping just one machine on the façade or balcony. It's the tidy, value choice from three rooms up, and often the only approvable option in historic centres. Fitted F-gas certified, with a VAT invoice and warranty. Free quote in 24h.

A multi-split is the same heat-pump technology as a single-split — just shared smartly across rooms. Here's when it's the right call.
Two to five indoor units run off a single condenser, so there's one machine outside instead of one per room — decisive when façade or balcony space is tight, which in Lisbon it usually is.
Neater pipework and a single point of noise outside. Condomínios and landlords far prefer one discreet unit to a façade full of condensers — it's often what gets an install approved.
Below three rooms, single-splits can be simpler. From three up, one larger outdoor unit usually beats buying three separate ones — you pay once for the condenser and share it.

Yes — that's its main advantage. Two to five indoor units share a single outdoor condenser, so there's one machine outside instead of one per room. In historic centres like Alfama, Baixa and Chiado, cutting to one outdoor unit can be what makes an install allowable at all.
Up to the outdoor unit's capacity. A multi-split is sized for a set number of indoor units, so if expansion is likely we size the condenser with headroom now. If your plans are very uncertain, single-splits added over time can be more flexible — we advise honestly in the quote.
Yes. Every indoor unit is a heat pump: it cools in summer and heats in winter with about three times less electricity than an electric heater. One system keeps the whole home comfortable all year.
Yes. AC in Portugal must be installed by an F-gas (gases fluorados) certified technician. Every multi-split is fitted by a certified, insured installer who issues a factura c/IVA and provides the workmanship warranty.
