During summer, air-conditioning systems must maintain what maximum temperature in resident areas?

The maximum temperature that air-conditioning systems should maintain in resident areas during summer is typically set at 85 degrees Fahrenheit. This standard is recommended to ensure comfort and safety for residents, especially in areas prone to high temperatures. An indoor temperature above this threshold can lead to discomfort, heat stress, and potential health risks, particularly for vulnerable populations such as the elderly or those with pre-existing health conditions.

Air-conditioning systems are designed to create a balance between energy efficiency and occupant comfort. Setting the maximum allowable temperature at 85 degrees F is a way to ensure that air conditioning systems are not overburdened, while still maintaining a reasonably comfortable environment within homes and facilities. Temperatures higher than this can make indoor spaces uncomfortable, leading to complaints and a potential decrease in overall well-being for the residents.
