Sure, but since the rises are not just in areas that are doing a lot of air conditioning, that can't account for more than a small fraction of the rises. After all the rise is being seen without air conditioning, and when you take that amount out of the rise seen in the south, you end up with the rise that can be due to air conditioning, and that can't be all that much.

Besides, for the years I lived in south Florida, I only remember being able to turn off the air conditioner for a few days each year, and that was in late December and early January, before the virus showed up. South Florida is one of the places that is seeing a rise, now, but didn't see a huge initial outbreak, despite the fact that most everybody would have been using air conditioners since February.

So, while it does make sense, I don't buy it as a significant factor in the recent outbreaks.
