Why Europe Doesn't "Do AC" Like the US (And How to Stay Cool Anyway)
Why your European hotel room might not feel as cool as you expect
If you’ve traveled to Europe in the summer, you’ve probably had this moment: you open the door to your hotel room (maybe even at a beautiful five-star property) and realize there’s no air conditioning, or the AC that is there isn’t doing much. It catches a lot of travelers off guard, because in the US, AC is just… there. In Europe, it’s an exception more often than the rule. Here’s why, and what you can actually do about it.
It’s Not the Hotel’s Fault — It’s the Charm You Came For
Much of Europe’s hotel inventory sits inside buildings that are decades or centuries old — the same character and history that make a trip to Europe worth taking in the first place. Retrofitting a 400-year-old palazzo or a historic townhouse with ductwork isn’t a quick fix; it’s often expensive, sometimes structurally impossible, and frequently restricted by historic preservation laws.
So even well-run, high-end properties may simply not have the infrastructure for central air. It’s really no one’s fault. It’s the trade-off that comes with staying somewhere centuries old instead of somewhere built last year — and for a lot of travelers, that trade-off is exactly the point. It’s part of the same story behind why 4- and 5-star hotels in Europe don’t always look or feel like their US counterparts — the ratings reflect a different set of standards and priorities altogether.
In Some Countries, It’s Actually the Law
This part surprises people: in several European countries, AC isn’t just uncommon; it’s legally restricted.
Spain, Italy, and Greece all currently limit how cold air conditioning can be set in public buildings during summer, typically no lower than around 27°C (80°F). The rules trace back to 2022 energy-saving measures introduced during the European energy crisis, and while the specific decrees have been revised and renewed since, the underlying practice has largely stuck. They typically apply to shops, transit stations, offices, and hotel common areas like lobbies and restaurants. Hotel guest rooms are generally treated as private space and exempt, meaning you can usually still control the temperature in your own room.
Because these rules shift periodically, the exact numbers can vary by year and country. It’s important to note that countries in Southern Europe, where it gets the hottest, are thinking about adopting similar measures in the near future. The pattern to remember is simple: even where AC exists, public and shared spaces may feel warmer than you’d expect by US standards, regardless of the property’s star rating.
Heads up: AC regulations across the EU are a moving target and get revised often. Depending on when you’re reading this, it’s worth doing a quick search for the latest news on AC rules in your destination before you go just to make sure nothing’s changed since this was published.
In Some Countries, There’s Just Not Much Need
Then there’s a different reason entirely: climate. Countries like Germany, Austria, Switzerland, and the UK generally have short, mild summers, with only a few genuinely hot weeks each year. Building out full AC infrastructure for a short stretch of warm weather is a significant cost for a benefit that’s only needed occasionally, so most homes, and many hotels, simply haven’t invested in it. It’s less a gap and more a rational trade-off. In Alpine regions specifically, that often means relying on cool mountain air and open windows instead.
The UK shows the same pattern outside the Alps: as of a 2026 University of Reading study, only about 4.3% of homes in England use air conditioning, even as heatwaves have become more frequent. Across the continent as a whole, only about 20% of buildings have air conditioning today, compared to roughly 90% in the US.
The Regional Cheat Sheet
This isn’t every country we work in — browse our full list of European destinations for that — but here’s the general pattern by region:
- Southern Europe (Italy, Spain, Greece, Portugal) — Highest AC availability but check whether it’s building-wide or unit-specific and know that public spaces may be capped by law even when your room isn’t.
- Central and Alpine Europe (Germany, Austria, Switzerland) — AC is genuinely rare outside major hotel chains, since it’s typically only needed a few weeks a year.
- UK and Ireland — AC is still uncommon in homes and many hotels, though installations are rising quickly as summers get hotter. Confirm before booking, especially outside major chain hotels.
- Central and Eastern Europe (Czechia, Poland, Hungary, Slovakia, Slovenia, and neighboring countries) — A similar story to Alpine Europe: shorter, milder summers mean AC is less of a given, though this varies quite a bit by city and property.
- The Nordics (Sweden, Norway, Denmark, Finland) — Historically among the least likely to have AC at all, for the same climate reasons as Central Europe, though that’s beginning to shift as summers warm.
- Major cities vs. smaller towns — Larger international-brand hotels are more likely to have reliable cooling than boutique or countryside properties.
- Private rentals and apartments — Assume no AC unless it’s explicitly confirmed in the listing.
How to Stay Cool Anyway
None of this means you’re stuck sweating it out. A few things that genuinely help:
- Pack a portable fan. Small battery or USB-powered fans are inexpensive, pack flat, and make a real difference overnight or while out sightseeing in the heat.
- Bring a cooling towel. These stay cool for hours with just a splash of water and are great for midday sightseeing breaks.
- Choose breathable fabrics. Lightweight cotton and linen beat synthetic blends in the heat, and dry faster too.
- Use the room strategically. Close shutters or blinds during the hottest part of the day to block direct sun, then open windows in the early morning and evening to let cooler air in.
- Expect windows without screens. Many older European buildings don’t have window screens, so an open window for airflow can also mean the occasional bug. A small travel repellent or a compact mosquito net can help if that bothers you.
- Ask about AC fees. Some hotels, particularly in Italy, charge a nightly surcharge — often around €10 (roughly $11 USD) — for in-room air conditioning. It’s worth confirming at booking so there’s no surprise at checkout.
- Ask before you book. If AC matters to you, ask specifically what kind of cooling a property has — building-wide, in-room unit, or none — rather than assuming.
- Consider shoulder season. Traveling in May, June, or September instead of peak July/August means cooler days, smaller crowds, and often better rates.

The Bottom Line
Air conditioning in Europe isn’t broken, and it’s not something to apologize for — it’s a mix of old buildings, real energy rules, and climates that genuinely don’t need it most of the year. Knowing that ahead of time turns a frustrating surprise into just another part of the European travel experience.
Plan Ahead, Stay Cool
The best way to avoid an AC surprise is to ask about it before you book. If you’re a traveler reading this, we recommend booking with your local or preferred Travel Advisor to experience Europe without any unnecessary hiccups — they’re usually the expert, and they’ll know which properties deliver reliable cooling and which ones don’t.
