With the outside air at 90 and a RH of 50%, the inside temp at 80, with a
differential of 1.5 degrees, my A/C is on for 30 minutes and off for 40
minutes.

Is this 3t A/C sized correctly? I would like to know because the A/C is
getting old and I want to replace it with a new one. If this one is sized
correctly I will know what size to look for .

Thank you

You might want to poke around the web sites of a few mfgs to see if they have
