Alfama is Lisbon's oldest quarter — winding lanes, protected façades and thick old walls. Installing AC here takes local know-how: we plan the outdoor unit around the rules, handle the tricky access, and where a fixed install genuinely isn't allowed we tell you honestly and point to a portable alternative. F-gas certified, VAT invoice and warranty. Free, honest advice within 24 hours.
Brought to you by the local team behind AC Rental Lisbon — years of keeping Lisbon homes and apartments comfortable.
Alfama, Mouraria and Castelo are among the most protected, most awkward-to-access streets in Lisbon. Here's how we approach them honestly.
On many streets, an outdoor unit on the street-facing façade simply isn't allowed. We look for an internal courtyard, light well or rear elevation — and if there's genuinely no compliant spot, we say so rather than fit something that gets you in trouble.
Narrow lanes, steep steps and no lift make the physical job harder. Our teams plan the carry and keep the copper run short and clean, so the work is tidy despite the constraints.
Old thick walls actually hold temperature well. Many Alfama flats are short-term rentals — a heat pump cools in summer and heats in winter, keeping guests comfortable year-round from one discreet system.

Annual maintenance (clean + gas check): ~€60–180 per unit. Prices are indicative guide ranges, not a quote. For the full breakdown see our AC installation cost guide.
From Alfama and the Sé to Mouraria, Castelo and Graça — the historic heart of Lisbon, handled with care.
This is the historic core — read our detailed guide to AC in a historic Lisbon apartment, see the main AC installation in Lisbon page, or if a fixed unit isn't possible consider portable AC rental.
Often yes, but not always. In protected streets an outdoor unit on the street façade may not be allowed. We assess your building for a compliant spot — internal courtyard, light well or rear elevation — and if none exists we tell you honestly and suggest a portable alternative rather than an install that breaks the rules.
For the outdoor unit on a façade or common area, usually yes — the condomínio and, in classified zones, the câmara can have a say. Inside your flat, no. We help you understand what applies to your specific building before any work.
It's part of the job here. Our teams plan the access, the carry up the stairs and the pipe route in advance, keep the copper run short, and leave the work clean. Tight logistics are normal in Alfama — experience is what makes it smooth.
Then we say so — we won't fit something non-compliant. A good alternative is a portable air conditioner from our sister company AC Rental Lisbon: no drilling, no outdoor unit, delivered across the historic centre. It's often the sensible route for protected buildings and short stays.
For many hosts, yes — guests increasingly expect AC and it shows in reviews. A heat pump cools in summer and heats in the cooler months, comfortable year-round from one unit. Where a fixed install isn't possible, a portable keeps guests happy in the meantime.
Yes. AC in Portugal 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.
