 But as you said, we've been talking a lot about those heat waves. You know, to be fair, over the last five decades, the country has faced more than 700 heat waves. But many say that this summer's heat, severe and unrelenting heat is among the worst. And as a result, some say that sales of air conditioners could grow by some 60 percent this summer. That's up from the usual 25 to 30 percent. So it's more than double the growth of the usual year.
