willis carrier's igloo in the 1939 new york world's fair gave visitors a glimpse into the future of air conditioning, but before it became popular, world war ii began. during the post-war economic boom of the 1950s, air conditioning began its tremendous growth in popularity. today, air-conditioning and hvac is a staple in many american homes. ceiling fans and air conditioning are often used in conjunction; in summer, a ceiling fan allows the thermostat to be set several degrees higher; in winter, a fan can be set to a low speed on reverse direction to bring down stratified heat from the heating system.

the r38 was the first subway car fleet to have air conditioning installed. the last ten cars delivered (4140–4149) came factory equipped with stone safety 10-ton split system air conditioning system featuring the compressor/condenser units mounted under the cars, while the evaporator units were installed on the top interior ends of the car in 1967. the first six air conditioned cars came into service on the f train on july 19, 1967. the six-week experiment was a success after past failures and air conditioning would soon, but not immediately, become standard equipment on new rolling stock built for the system, since the first 200 r40 cars were built without air conditioning. the air conditioned cars cost $40,000 more than the non-air conditioned cars. from this point on, the new york city transit authority began adopting air conditioning as standard equipment on all new cars, and older model cars were retrofitted with ac units to make life much more bearable throughout the subway system. the stone safety air conditioning system was adopted from their standard railroad and commuter coach air conditioning systems, and it proved very successful.
