Air conditioning not cooling? The simple trick to fix it in Spain without calling a technician.

The heat wave announced last week by the State Meteorological Agency ( AEMET ) continued this Monday with twelve stations in the state agency's network reporting maximum temperatures above 41ºC and four exceeding 42ºC, according to the summary of significant phenomena prepared by AEMET spokesman José Luis Camacho .

More specifically, the stations with temperatures above 42ºC were Ribadavia in Ourense, which reached 42.8ºC; Montoro, Vega Armijo , in Córdoba (42.7ºC); Bailén in Jaén ; and Villanueva del Arzobispo, both in Jaén (both with 42.1ºC). That's saying something.

And the worst part is that the weather forecast doesn't look like it's going to improve in the coming weeks. That's why many Spaniards have taken measures to avoid the effects of this summer period: from staying hydrated to wearing lightweight, light-colored clothing and seeking cool, shady spots ...

And, of course, use the fan and air conditioning. A large percentage of Spanish society has a major problem with the latter. Even when the fan is set to maximum, the air still doesn't cool down as it should .

Fortunately, there's a quick and easy solution that has gone viral on social media—especially TikTok—in just a few days and that we can do ourselves at home , without having to hire a technician or spend money. It involves cleaning the air conditioning filter.

Apparently, the problem with the appliance not cooling may be related to the indoor unit's filters not being cleaned. The procedure is very simple . The first step is to open the appliance's lid, without being afraid to use a little force to open it.

In second place, We must carefully remove the filter and wash it immediately. We should do this with water only, without using sponges, brushes, or our hands , as this could damage it. In addition, it's advisable to install a surge protector and check the thermostat and its location.

If, after following these recommendations, the air conditioner still isn't cooling properly , it's likely that it has lost its freezing gas or has a more serious problem. In this case, we should contact a professional technician for a thorough inspection of the unit .
