Sintra's microclimate is its own beast — cooler, greener and far damper than Lisbon. We install heat-pump air conditioning that cools in summer, heats efficiently in winter and helps dry out the damp, fitted by F-gas certified installers with a VAT invoice and warranty. 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.
Sintra isn't just Lisbon with hills. The microclimate and the older, protected buildings shape what we install.
Sintra holds moisture — stone houses feel cold and damp for months. A modern heat pump doesn't just cool in summer; it heats efficiently in winter and helps keep humidity down, so the house feels dry and healthy.
Parts of Sintra are UNESCO-listed and heritage rules are strict. We plan discreet placement for the outdoor unit and, where a façade fitting isn't allowed, work out a compliant alternative before quoting.
Quintas and older homes often have poor insulation and long internal runs. We size the system to the real building — not a spec sheet — so it actually keeps you comfortable without running flat out.
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 and the building. Older Sintra houses with long runs can sit higher — the free quote gives you the exact figure.
Yes. A modern split is a heat pump, and in cooling or dry mode it removes moisture from the air. Run sensibly through the damp months it keeps humidity down and the house feeling dry — a real difference in Sintra's climate. For heavy damp we can also advise a dedicated dehumidifier.
Yes — that's the point of a heat pump. It heats in winter with about three times less electricity than an electric heater, so a Sintra home stays warm and dry all year on low running costs, from a single system.
Often, yes, but with care. In heritage and protected zones the outdoor unit placement can be restricted. We advise on discreet, compliant placement and, where a fixed unit truly isn't allowed, point you to a portable alternative.
Yes. In Portugal, AC must be installed by an F-gas (gases fluorados) certified technician. Every install is done by a certified, insured installer who issues a factura c/IVA and gives the workmanship warranty.
We send the quote within 24 hours. After you confirm, a single-split is usually fitted in a few hours and a whole-home multi-split over one to two days. We confirm the dates in your quote.
