When was the boom for AC units?

[Guest guest]

Do you remember what year it was (approximately) when AC units became

so affordable that ordinary people started to buy them on a large scale?

If I remember well, in my country it was the beginning of 1990s.

Before that time one couldn't just walk into a store and buy an AC

unit for himself. Sure, they existed in large state institutions such

as banks, post offices but I suppose those were well maintained.

I think all my problems started with the mass production of AC units.

Their rise in popularity has brough about the downfall of my health.
