Window type aircon (inverter)

[dr. d]

when we were kids, our use of the aircon was dictated from above.
"ten hours lang ang aircon. 8 pm to 6 am. and absolutely no aircon in the daytime."
yes, the aircon did last several years, but we weren't too happy with its limited use.

i suspect,
the limited use of aircon was to save on electricity... increased aircon longevity was a happenstance secondary effect.
heh heh.
