How unfortunate for you. In my kitchen, it is 73ºF and comfortable. Outside my kitchen, it is currently 98ºF. So the A/C is working. But it runs all day on days like this, no spare capacity. If you fail to crank it up by 10AM on a day like today, it won't keep up. But the worst I've seen here is high 70's inside on a 90º+ day where we didn't start it until noon or 1PM.

It's a new unit, much more efficient than the one it replaced. And on more moderate days (80's, humid) it has less trouble keeping up with it. We only really get 5-10 days this hot each season.
