The PoD isn't for air conditioning to not be developed, but for it to be less common. For example, France is a wealthy developed country with low electricity prices, but air conditioning isn't common there.
Fewer million people emigrate to hot American states south of the Amazon-Dixon Line.
Far fewer white folks in Southern California, which means that Latinos might still dominate.
No gentrification of Atlanta means far fewer corporate headquarters moving from Northern States.
Without air conditioning, fewer factories migrate to the Virginias, the Carolinas, etc. meaning that Rust Belt cities retain much of their 1960s-vintage economic clout.
Lower population density means fewer deaths when Hurricane Katrina hits New Orleans.
Fewer old folks retire to Florida and Arizona.

Arizona can use a swamp cooler not as comfortable but better then fans.

If you go down the route of A/C being feasible but uneconomic for small-scale use, computing may be a case where the heat load forces you to accept the cost. That makes server farms more expensive to run, of course.
Liquid cooling with forced-draught radiators is an option too, of course; whether that's preferable to expensive air conditioning systems depends on cost.
It's also not as common in some parts of the US. In Washington State you can buy cars that don't have air conditioning. When I lived in Massachusetts, my place didn't have air conditioning (I bought a wall unit).
Perhaps rather than a technological POD, have some seriously whacko cultural troglodytes make a successful case for Air Conditioning being unhealthy, for whatever reason (like anti-vaxxers on steroids). Then you would have the tech, merely unused due to cultural norms. People might even brag about sweating in the summertime.
The first recognized cases of Legionnaires' disease occurred in 1976 in Philadelphia, Pennsylvania. Among more than 2000 attendees of a Legionnaires' convention held at the Bellevue-Stratford Hotel, 221 attendees contracted the disease and 34 of them died.[38]
In April 1985, 175 people in Stafford, England, were admitted to the District or Kingsmead Stafford Hospitals with chest infection or pneumonia. A total of 28 people died. Medical diagnosis showed that Legionnaires' disease was responsible and the immediate epidemiological investigation traced the source of the infection to the air-conditioning cooling tower on the roof of Stafford District Hospital.
Legionaires Disease. There was a flutter of concern about the connection with ducted A/C in the hotel where there were several respiratory related deaths during an American Legion convention in 1976.
Likewise in northern Ohio. Of all the rental houses I lived in during my years in Cleveland, only ONE of them had central air. In the rest I relied on the lake breeze (I lived within half a mile of the shoreline), fans, and cold showers. I'm sound-sensitive, so window air conditioners really weren't an option for me -- listening to that much noise will destroy my sanity faster than sweltering heat and humidity will.In Massachusetts, it's unusual to have central AC, but it's considerably more common in new(er) or nicer homes. I live in a place that was built around 1960, and it has a central air system from that era that I still can't believe survived this long.
You can live without air conditioning in New England if you must, but there are at least a few weeks in the summer in which the heat and humidity combined makes that an utterly miserable experience.
But swamp coolers won't work where you have real swamps, like Florida, high heat and humidity
All you need is to have a major hotel install AC in the mid-Fifties and have one of these things happen? Might work, if the panic mill gets going on it.
