The ideal setting depends on balancing comfort and efficiency. For most people, a comfortable range in summer is 23–25°C, while in winter it’s 20–22°C. These settings help your air conditioner run efficiently without overworking. Keep in mind that comfort can vary depending on the room, the system type, and personal factors — young children, the elderly, or people with health conditions may prefer slightly different temperatures.
