Stop in for a cup of coffee

My a/c barely keeps up in triple digit temps. And by keeps up I mean 80 in the house. 92 forecasted for the high today, coolest day of the week. Think I’ll take the Duster to work.
I set our thermostat to 77°. Seems to be just right. It was under charged last year and wouldn't keep up. I gave it a shot if R22 this spring and it is working good even with 90° temps. It is a old system though. I am guessing 40-50 years old. ( we have lived here 25 years and it was old when we moved in) LOL
