OSAKA, Japan--(BUSINESS WIRE)--Daikin Industries, Ltd., a leading global HVAC&R (Heating, Ventilation, Air Conditioning, and Refrigeration) manufacturer, has conducted the inaugural "Daikin World Air Survey." It primarily highlights how people in 12 cities worldwide perceive and use air conditioners in their daily lives, exploring the differences and commonalities among these cities. The aim of the survey is to raise awareness of air conditioners and air, which are crucial for maintaining a comfortable and healthy life, among a global audience.

Based on the survey, Daikin calculated the “average number of hours of air conditioner use when spending all day at home in the hottest month of the year.” People in Houston were found to use air conditioners the longest with 17.2 hours, and a surprising 41% of Houston residents used them for 24 hours. The cities with the second and third longest hours of use were Riyadh, Saudi Arabia, at 14.9 hours, and New York at 12.6 hours. It seems to be commonplace for people in the U.S., where central air conditioning systems are widely adopted, to “leave their air conditioners on all the time” rather than turning them on and off frequently.
