With the troubles in Ukraine slowly drawing NATO into the conflict, France has more immediate concerns than air conditioning at the Summer Olympics. President Macron has not ruled out sending regular French troops to Ukraine. If the Ukrainian military fails in their ability to stop the Russian invasion, the NATO countries will have to decide whether to let Russia succeed. I think Macron and the British may be looking at the Crimean War as a model, when British, French, and Ottoman troops were used to stop Russian expansion into former Ottoman territory. If that happens, it is probable the Olympics will be suspended, as they were in 1940 and 1944.
At the very least, I'll send NATO troops to Kyiv. So at least the Ukrainian government will survive in Kyiv even if it becomes a rump state.
