There could be several reasons why hotels often keep the air conditioning (AC) running even when guests close the windows or request adjustments:
Air Circulation and Freshness: Running the AC helps maintain a constant circulation of fresh, filtered air throughout the room, which can improve indoor air quality and comfort.
Humidity Control: AC systems also help control humidity levels in the room, preventing excess moisture that could lead to mold and mildew growth.
Temperature Regulation: Hotels aim to provide a consistent and comfortable temperature for guests regardless of the outside weather conditions.
Quick Cooling: Turning off the AC might lead to a stuffy or warm room, especially if the weather is hot outside. Keeping it running allows for a quick cool-down when guests return to their rooms.
Energy Efficiency: Modern HVAC systems are designed to be energy-efficient, and the cost of running the AC continuously might not be significantly higher compared to the energy required to power it on and off frequently.
Guest Preferences: Some guests might prefer a cooler room for sleeping or working, and by keeping the AC running, hotels cater to a broader range of preferences.
Hotel Policies: Hotels often have standardized policies regarding room temperature to ensure a consistent experience for all guests.
Maintenance Considerations: Running the AC continuously might help prevent potential issues that could arise from frequent on/off cycles.
However, it's important to note that not all hotels follow the same practices, and individual policies can vary. If a guest finds the room temperature uncomfortable, it's best to communicate their preferences with the hotel staff, who might be able to adjust the AC settings or offer alternative solutions. Some hotels now offer more advanced climate control systems that allow guests to set their desired temperature within specific limits, giving them more control over their room's environment.
