Does It Have AC? Heat-Readiness Atlas for Renting or Buying a Home in Europe (2026): 27 Countries, Viewing Checklist and Lease Clauses

An 11-chapter atlas you read online or print, with a spreadsheet, for tenants, expats and buyers looking at a home in Europe who want to know whether homes in that country have air conditioning, how hot this particular home will get, and what to ask before they sign.

In Cyprus nearly every home has air conditioning; in Sweden almost none does, and in Belgium or Austria a flat under the roof can be unbearable for a fortnight with nothing on the wall but a radiator. Listings do not help: "air conditioning" may be one tired unit in the living room, "pre-installation" means pipes and no machine, "heat pump" may not cool at all. This atlas gives you the country, then a method for the home in front of you.

Every country figure names its source: Eurostat cooling degree days (nrg_chdd_a), the share of household energy used for cooling in 2024 (nrg_d_hhq) and household electricity prices for the second half of 2025 (nrg_pc_204), all read on November 7, 2026; July highs, ownership estimates and local rules come from the Claude AC country pages and are labelled as such. The heat-risk score is our method, said so on the page, not a standard. We do not let, sell or install homes or air conditioners and take no commission.

• Four lease clauses (units let with the home, repair in summer, the right to install, shading), four questions for a seller and three messages ready to send.

Who it is for

• Tenants and expats moving to another European country who want to know whether homes there have air conditioning, and what to ask before signing a lease
• Buyers comparing homes or countries who want to judge, at the viewing, how hot a dwelling will get and what it will take to cool it
• Anyone who has found a top-floor flat, an attic or a home with big windows and wants a method rather than a guess

Introduction

"Does it have air conditioning?" gets very different answers across Europe. In Cyprus and Malta nearly every home does. In Sweden almost none does, and the few that cool do it with a heat pump bought for winter. In Belgium, Germany or Austria a flat under the roof can be unbearable for a fortnight a year with nothing on the wall but a radiator. The listing rarely helps: "air conditioning" may mean a 20-year-old unit in one room, "pre-installation" may mean pipes and no machine, and "heat pump" may mean a system that cannot cool at all.

This atlas gives you the answer for the country, then the method for the home in front of you. Chapter 1 sets out the four figures behind each country sheet and a table of all 27 countries. Chapter 2 turns the country and the dwelling into a heat-risk score with four levels, from "fans and shading will do" to "do not sign without cooling or the right to install it". Chapters 3 to 5 are the 27 country sheets, from Ireland to Cyprus. Chapter 6 is a 20-point checklist for the viewing; chapter 7 covers a unit that is already installed; chapter 8, who has to say yes before you fit one. Chapter 9 works out the electricity of a summer at your country’s price. Chapter 10 gives four lease clauses to ask for and four questions for a seller, and chapter 11 three messages ready to send.

How to use it: read your country’s sheet, then take chapters 2 and 6 to the viewing. Print it (Ctrl+P or Cmd+P, then "Save as PDF", or print on paper). The 27-country table, the heat-risk score and the summer cost calculator are also on your access page as a spreadsheet.

The figures were read from Eurostat on November 7, 2026: cooling degree days by country (dataset nrg_chdd_a, updated May 8, 2026), the disaggregated final energy consumption of households (nrg_d_hhq, 2024, updated June 9, 2026) and household electricity prices for the second half of 2025, consumption band 2,500 to 4,999 kWh, all taxes included (nrg_pc_204). July highs, ownership estimates, heat records and local frameworks come from the Claude AC country pages and are labelled as such. The rules quoted were checked on EUR-Lex the same day. Every calculation is shown; hours of use and machine efficiencies in the worked examples are example inputs, not measurements of a real home.

Chapter 1: How to read the atlas: four figures per country

A country does not have one summer: Lisbon and the Alentejo, Milan and Palermo, Brussels and Liège do not need the same answer. The figures below describe the country as a whole; chapter 2 adds the local adjustment and the dwelling.

The four figures

1. Cooling degree days (Eurostat). Each day whose mean temperature reaches 24 °C counts, and adds its mean minus 21 °C; a day at a mean of 27 °C adds 6. The yearly total measures how much cooling a climate asks for. The EU averaged 111.6 a year over 2016–2025. The atlas gives the ten-year average and the last two years, because one hot summer (2018 in the north, 2024 in the south-east) can be several times a normal one.
2. The share of household energy used for cooling (Eurostat, 2024). What households actually spend on cooling, out of all their energy at home (heating, hot water, cooking, appliances). It says how far cooling has become normal: 0.84% for the EU, 15.98% in Cyprus. A zero means none was recorded in the national energy balance, which for some countries reflects how the data are collected rather than the absence of any unit.
3. The typical July high in the main cities and the heat on record (Claude AC country pages): what a summer feels like, and what a bad one did.
4. AC ownership and the local framework (Claude AC estimates, in words, never a false-precise percentage): how likely a listing is to have cooling, and who has a say before one is fitted.

Each sheet adds the household electricity price for the second half of 2025, the electricity of 100 hours of cooling at that price (chapter 9 explains it) and the words that mean air conditioning, heat pump or pre-installation in that country’s listings.

The heat band

The atlas sorts the 27 countries into six bands by their average cooling degree days, and gives each band its points for the score of chapter 2.

The 27 countries at a glance

Sorted from the lowest to the highest cooling need. CDD: Eurostat cooling degree days, average of 2016–2025 and the 2024 value (2025 is on each country sheet). Cooling share: the share of household energy used for cooling in 2024. July high: typical, main cities. €/kWh: the Eurostat household electricity price, second half of 2025, all taxes. "100 h": the electricity cost of 100 hours of cooling at an average output of 1.5 kW, with a split (SEER 6.5) and with a portable (EER 2.6), as in chapter 9. n/a: not published by Eurostat. *Serbia is placed by its July high.

What the figures cannot tell you

• The region. National averages hide the hottest places: the south of France, the Po valley, the Spanish and Portuguese interior, the Danube and Pannonian plains, Vienna. Chapter 2 adds one point for a town clearly hotter than its country and removes one for the coast or the mountains.
• The dwelling. A top-floor flat with west windows in Brussels can be hotter in a heatwave than a shaded ground floor in Athens. That is what the score is for.
• Next summer. The ten-year averages smooth out the record years. The sheets give 2024 and 2025 so you can see how far one summer can go.

Frequently asked questions

How do I receive the guide?

Right after payment you are taken to your guide page, with the spreadsheet to download. Bookmark it: the link stays valid and always shows the latest version. To keep a PDF, save it from your browser (Ctrl+P or Cmd+P, then "Save as PDF"): the layout is made for printing. Stripe emails you the receipt, and "Find my purchases" at the bottom of every page sends the link again.

Is VAT included? Is it a subscription?

€29 is the total you pay, VAT included, once. There is no subscription and nothing is charged later. Your card details go to Stripe and never reach us.

Does it tell me whether a particular flat has air conditioning?

No document can: that is the agent’s or the landlord’s answer. The atlas tells you how likely it is in the country, what the listing words really mean (installed units, pre-installation, a heat pump that may not cool), and gives you the questions and the message to get a written answer before the viewing.

I already have the Europe AC buyer’s pack. Is this the same?

No. The buyer’s pack chooses, sizes and prices the machine for a home you already live in. This atlas comes before: which country and which home, how hot it will get, what is already installed, who must agree to a unit, and what to put in the lease. The two sit well together if you then install.

My country is not in the atlas. Is it still useful?

The 27 sheets cover the countries of the Claude AC Europe section. Outside them, the heat-risk score, the viewing checklist, the chapter on installed units, the lease clauses and the summer cost method work anywhere; you only need your own electricity price.

Are the lease clauses legally valid?

They are wording to propose, not standard terms. Depending on your country, the law may already say the same thing, or may forbid part of it. Have both parties sign the lease or an addendum, and check with a tenants’ association or a lawyer if the stakes are high. Nothing in the atlas is legal advice.

What is the guarantee?

The guide is guaranteed as described: if it does not open or contains an error, we fix it, and if we cannot, we refund you in full (refund policy in the terms of sale). Write to admin@tech-bharat.com. A duplicate payment is always refunded.
