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. While air conditioning can improve sleep quality and filter allergens, medical experts clarify that it does not directly cause viral respiratory infections like the flu. However, continuous cooling removes indoor humidity, which can dry out nasal mucous membranes. 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, users are advised to use oscillation modes~~ Proper maintenance is critical for fans to avoid direct airflow on the body, which can cause dry eyes, nose, or throat. To prevent localized chilling, beds should not be positioned directly under air conditioning vents. Utilizing sleep modes or timers can help adjust to changing temperatures during the night.

Neglected equipment can accumulate dust mites and impurities, potentially triggering rhinitis or allergic reactions. ~~To mitigate these risks, professionals~~ Furthermore, neglected devices can consume up to 30% more electricity due to accumulated dust, pollen, and moisture. Professionals recommend washing air filters every four weeks with water and neutral soap, and performing comprehensive technical servicing every six months. For safety, the power supply should be disconnected from the main electrical panel before any inspection.
