Do your guests have good air conditioning habits?

Mostly, no. 89% of British households and 84% of German households have no air conditioning at home (YouGov, August 2026). Those two countries sent 8,4 million of the 15,7 million international tourists who stayed in the Balearics in 2025, and 88% of the Mallorca villas they rent list air conditioning. Most of the people using your AC this summer do so without the habits that come from living with it, and without ever seeing the bill.

Where your guests live, and where they stay

This summer a map of household air conditioning across Europe went round social media. We checked its pattern against the primary sources and drew our own.

• Where your guests live: Britain 11%, Germany 16%, France 30% of households with AC.
• Where your guests stay: holiday rentals, which are close to fully equipped. 87% of active Airbnb listings in Mallorca list AC, 88% of its villas and 92% of villas in Menorca. In Málaga it is 94% and in Sevilla 97%.
• Who they are: Germans (4,9 million) and Britons (3,5 million) were 53% of the Balearics' international tourists in 2025. Across Spain, the UK, France and Germany together made up 45% of 96,8 million.

What guests do at home on a hot day

The English Housing Survey asked households that overheat how they keep cool. 90% open the windows, 75% close the blinds and 59% switch on a fan. 7% use air conditioning.

That is the reflex guests pack in their suitcase. In the villa it meets equipment they rarely use:

• The window still opens. Fresh air is how a hot room gets cooled at home, so terrace doors stay open with the AC running.
• Colder looks faster. Without a feel for AC, 16°C seems like the quick way to cool down. A split unit does not reach comfort much sooner at 16°C. It runs longer and harder chasing a colder target.
• The AC stays on when they go out. At home there is no AC to leave on. On holiday the unit keeps cooling an empty room through a day at the beach.
• There is no meter in sight. At home the energy bill shapes behaviour. On holiday the price is all-inclusive.

None of this is careless. Guests are doing what works at home with equipment they rarely use. Guests who set 16°C can increase AC energy use by up to 70% compared to a 24°C setting.

Why the gap will stay open for a while

AC is spreading in the north. In Germany, Verivox measured 13% of households in 2023 and 19% in 2024, and more than two thirds of German units are portable. It is still a low base. Your 2027 guests will still mostly come from homes without fixed air conditioning.

Build the habit into the room

Guests who do not live with AC cannot be expected to know how to use it well, and they should not have to. The answer is to make the sensible choice the only one available, before the season starts.

• A floor on the temperature. A lower limit of 22°C keeps every room inside the recognised comfort band of roughly 22–26°C. Guests still choose their own temperature and fan speed above it. To someone arriving from a home without AC and a 33°C afternoon, 22°C feels cool.
• A timer for the empty room. The unit switches itself off after the time you choose, so an AC left running while everyone is at the beach stops drawing power.
• Set by the person who pays the bill. You set the limits once and hand the remote over with the room. Every stay runs inside them, with nothing for the guest to learn and nothing for staff to explain.

The two limits work together: the floor handles the cold setting, the timer handles the hours nobody is there. A holiday rental operator in Ibiza built Narveo after years of watching guests leave the AC running at 16°C all day, and the founder still uses it in his own properties.

How the Narveo Smart AC Remote sets those limits

The Narveo Smart AC Remote replaces the remote that came with your split unit. It ships preset to a recommended 22–25°C band, guests set any temperature inside it, and a timer switches the unit off after the time you choose.

Set up in under 2 minutes. No app. No WiFi. No installation. €69 per unit, and it pays for itself in one summer, within 30–75 days in a typical season.

The saving is €190–450 per AC unit per season: 20 units = €3.800–9.000. Coastal, cooling-only properties such as island villas sit near the floor of that range and year-round inland properties near the top. Work out your own season in the savings calculator.

Frequently asked questions

When Narveo is not the right solution

Narveo works with split air conditioners that guests operate by infrared remote, room by room. It does not control ducted central air or hotels run from a building management system. Properties in cool climates, or with little AC use, will recover less than the range suggests. A temperature limit and a timer do not close a terrace door, so a clear note at check-in still helps.
