Expert warns against setting air conditioning to 16°C after heat

As Europe endures intense summer heat, climatization expert Alejandro Hellín warns that setting an air conditioner to 16°C after returning to a hot home does not cool faster but increases electricity consumption. He advises letting the unit work under normal conditions instead of extreme settings Source: El Español. The Institute for Energy Diversification and Saving (IDAE) recommends 26°C as the ideal temperature for comfort and efficiency Source: Clarín.

Common mistakes

• Setting the thermostat to 16°C: The unit won't cool the room faster, but the compressor's extra effort raises energy use Source: La Vanguardia.
• Constantly switching the unit on and off: This is inefficient; experts recommend stable, prolonged operation Source: Clarín.
• Neglecting ventilation: Ventilating during cooler hours (early morning or night) reduces reliance on air conditioning Source: El Español.

Installation advice

Hellín notes that three separate units can cost about the same as installing a ducted system, which provides uniform temperature throughout the home. He uses ducted installation himself and claims he does not pay an exorbitant electricity bill Source: La Vanguardia.

What's next

With ongoing heatwaves, following these guidelines can help households reduce energy costs and environmental impact. The Spanish government's MITECO maintains guidance on extreme heat health risks Source: Clarín.
