It’s becoming clear how hot Spain gets during summer and for many pulling down the shutters down or using a fan doesn’t cut it. So what should homeowners and renters consider before thinking of installing an air-conditioner?
So you’ve probably realised that the only way you are going to survive the next two months is by installing an air conditioning unit. And quick.
But what are the rules? Is there anything stopping you and why on earth didn’t the previous occupants install one?
Well, for starters, they may have done and then decided to take it with them to their next residence. So don’t jump to the conclusion that just because there isn’t one, doesn’t mean there wasn’t.
However, there are rules and regulations in every building so you need to check.
If you rent the property:
If you are renting, first of all check your contract and see if there are any clauses about air-conditioning units. If there is no clause expressly forbidding air conditioning units, there may be something about making any kind of alterations to the property.
Article 23 of the Spanish Urban Leasing Law (Ley de Arrendamientos Urbanos or LAU) establishes that the tenant may not carry out works that modify the property without the written consent of the landlord.
It’s not clear exactly whether installing an air conditioner is classified as a “modification” by law but the only way to avoid problems is to check with your landlord. Try to reason with them that the property is too hot and becoming unliveable, and that future tenants are likely to experience the same issues.
To avoid problems and potentially having to remove the air conditioner and return the property to its original state at the end of the tenancy, write a written request, providing details of air-conditioning unit, its brand, dimensions, etc and where you plan to install it and ensure you get written consent.

If you own the property:
You might think it would be easier if you own the property but you may still have to check what rules apply to air conditioning units in your building and seek permission from the comunidad – residents community.
Comunidad rules and regulations:
Unfortunately, these differ from building to building depending on the whim of the homeowner’s association.
Sometimes, air conditioning units are banned from the façade of the building for reasons of aesthetics. Other times there are rules in placed as to where exactly the units can be place in order to limit noise.
If there are no particular ‘statutes’ laid down by the homeowners’ association then you will still need permission and this can be sought with a request put to an “owners’ meeting”. Usually, a majority vote is all that is needed for consent.

Rules set by your town hall
Some local councils lay down laws about air conditioning units, the type that can be installed and their location.
There could be rules about the distance they should be from a neighbours window and also about how noisy they are and what hours they can be used.
So always check with your ayuntamiento to avoid sanctions.
What next?
Once you have the consent you need and have checked the rules in your local area, then find the air conditioning unit you want.
Usually air-cons are installed on balconies, so you need to make sure you have enough space. If you don’t or don’t have a balcony then it may need to be attached to the wall of your building instead.
If you want air-con in multiple rooms, you can get a split converter and tubes installed to various indoor units in your home.
What’s the cost?
According to the Habitissimo website, the average cost of installing an air conditioner in Spain in 2025 is €2,300, with the lowest price being €800 and the highest €5,000.
An air conditioner consumes between 1 and 2 kWh per hour, with an average cost of between €50 and €100 per month per household during the summer (July to September), according comparison site Kelisto.
In order to keep costs low, experts agree that you shouldn’t turn the temperature of the unit down to less than 22C, and 24-26C is best.
As you need to keep the doors closed for it to work well, you really need one unit per room you want to cool. If you can’t afford to install one in every room, think about which rooms may need it the most – a bedroom or home office for example.

Air-conditioners can be noisy, so check the noise level before choosing one.
If you discover it’s just too complicated to install an air conditioning unit, then you may want to opt for a pingüino – or a penguin as portable air conditioning units are dubbed in Spain. Basically the bigger they are, the more effective but some require an outlet hose that can go through a window.
Bear in mind too that they can be expensive to run.
If all else fails, just do what the Spanish do. Roll down the shutters, turn off the lights and siesta through the hottest part of the day.
