I had friend over and try to lower my temp to 72 and it took awhile to get several degrees lower. I thought I had a problem.
I had my A/C checked by Chuck Farrell and he said everything was fine. He said even newer units were having problems in this extreme heat. My unit is 18 years old.
I said it must have one foot on the banana peel and the other foot in the coffin.

He recommended having it replaced in the winter months and to watch my bills as they will be higher than usual in this extremely hot summer.
Man, it's been hot, hot, hot.
