Air conditioning usage and efficiency guidelines

Overview

Guidelines for air conditioning usage emphasize health, energy efficiency, and proper maintenance.

To prevent respiratory issues and thermal shock, experts recommend maintaining indoor temperatures between 24°C and 27°C. The Sociedad Española de Medicina de Familia y Comunitaria (semFYC) warns that maintaining a difference of more than 6-8°C between indoor and outdoor environments can lead to dry mucous membranes, throat irritation, blood pressure alterations, fatigue, and dizziness. These risks are particularly high for children, the elderly, pregnant women, and those with chronic cardiovascular or respiratory conditions.

Energy efficiency is heavily influenced by thermostat settings. Reducing the temperature by even one degree can increase energy consumption by approximately 6% to 8%. Energy consultant Alex Bermudez notes that leaving units on overnight has a minimal impact, costing only a few cents per night. To optimize efficiency, Bermúdez recommends maintaining a constant temperature between 23°C and 25°C. In France, the agency ADEME suggests not dropping below 26°C, noting that increasing the temperature from 23°C to 26°C can reduce cooling needs by two-thirds.

For overnight use, specific household tips can mitigate physical discomfort. To avoid dry eyes, nose, or throat, users are advised not to let fan airflow blow directly onto the body, suggesting oscillation modes instead. Regarding air conditioning, it is recommended to avoid positioning beds directly under vents to prevent localized chilling. Utilizing sleep modes or timers can help adjust to changing temperatures during the night, while monitoring humidity levels remains important to combat dry indoor air.
