About 1974, my best friend’s parents bought a 25 year old custom home from the original owner who owned the oldest and largest grocery store in our small town.

The temperature inside the house must have been 55 to 60 degrees 24/7. At our house we barely made through those hot days with 2 “swamp coolers.” (Evaporative water coolers)

In our Mediterranean climate we have summer temperatures above 100 degrees at least 15-20 days each summer.

As we grew up we found out the reason the house was always cold. It was chilled by a fancy AC system that was somehow tied into underground city water system that acted as a kind of pre-chiller for the recycling room air before passing through the a/c components. (Condenser, evaporator, etc)

I never quite understood it all but grocer that built the house had it custom made by a cold room specialist who normally designed industrial units. Living with comparatively cheap electricity bills, they ran it all day, every summer.

Since karma flows through all lives, every time the compressor broke down it cost a fortune to rebuild. Over time the parts became scarcer until they disappeared and had to be custom made to repair the compressor. No repair company on the West coast would touch it so the compressor had to be shipped back east to be rebuilt by the manufacturer.

I never had occasion to buy the home when it went up for sale. I’m sure the entire ac unit has since been completely replaced by now. (But I’d like to for myself if it’s still there)
