Despite Spain being a country where summers are increasingly hot, the housing stock equipped with air conditioning in Spain is 47% of the total, according to a study published by idealista.com.
But there are huge differences depending on the point of the country where we focus. In the province formed by Lanzarote, Fuerteventura, and Gran Canaria, only 14% of homes have air conditioning.
In the western province of Santa Cruz de Tenerife, the percentage rises to 20% of homes.
To obtain these results, idealista analyzed more than 613,000 homes for sale and rent that were advertised in its database in June 2026.
Málaga leads the provincial ranking with 71% of its homes on the market equipped with air conditioning, followed by Balearic Islands (69%), Seville (68%), and Córdoba (64%).
The province of Madrid reaches 61%, while Alicante (60%), Valencia (57%), Jaén (54%), Almería (53%), Murcia (52%), Badajoz (51%), and Castellón (50%) also widely exceed the national average of 47%.
At the opposite extreme, the northern provinces show lower air conditioning rates. Asturias, Cantabria, and Burgos lead the ranking of least air-conditioned provinces with barely 1% of their homes, while Álava, Lugo, and A Coruña also do not exceed 2%.
The data for provincial capitals are similar. In the city of Seville, 74% of homes on the market have air conditioning, and in Córdoba, 72% do. They are followed by Palma, with 68%; Valencia, with 67%; Madrid, with 66%; and Jaén, with 65%.
The group of cities where more than 60% of the stock is air-conditioned is completed by Barcelona and Málaga (61%), while Murcia (59%), Alicante (58%), Ciudad Real, and Toledo (55% in both cases) also show high rates.
On the opposite side are the cities in the north of the peninsula, where, despite being traditionally cooler at this time, they are also prone to heatwaves. In Burgos, A Coruña, and Oviedo, only 1% of homes on the market have air conditioning. Santander, Vitoria, and Lugo barely exceed 2%, while Pontevedra has 3%.
Differences between purchase and rental
It is significant that the housing stock for sale and rent have different air conditioning rates. In Spain, 58% of homes for rent have this amenity, while only 43% of those for sale have it.
The most probable explanation for this difference is that tenants value air conditioning as an extra, while when buying a home, it is not as critical, since its installation is economical in relation to the acquisition cost.
Thus, 86% of homes for rent in the city of Seville have a climate control system, compared to 65% of those for sale. In Córdoba, 82% of homes for rent have it, compared to 68% of those for sale. In Madrid, 77% of homes for rent have air conditioning, while 57% of those for sale also have it. In Barcelona, 79% of homes for rent are air-conditioned, compared to 55% of homes for sale.
At the bottom of the table, the situation is similar. Teruel and Oviedo are the only capitals where none of the homes for rent have air conditioning, while Burgos, Lugo, and Vitoria register practically testimonial percentages.
