Anecdotal evidence but my ex boyfriend was an HVAC technician and frequently serviced suburban households. He was always stunned at how cold most customers wanted their homes in the summer. "theyre like chubby little eskimos in front of the TV" he used to chuckle, and most would ardently refuse energy saving ideas like acclimating to 75 degrees in the home, installing ceiling fans, or opening windows instead of running the HVAC system. Most people would just run the system constantly until the blower died or the compressor burned up every six or seven years.
Summertime is supposed to get a little warm :).
