Re: Another a/c issue.
Your problem sounds similar to what I used to experience. When it's in the 90s outside, the AC would run continuously but it would never get below 77 indoors.
Check the air temperature right after the evaporator when the AC is running. It should be around 55. If higher, your AC has problems. If around 55, check the temperature at the vents. If it's around the same temperature but the room is much warmer, heat is getting into the house faster than you can pump it out.
I have an old rancher with maybe 12" of batt insulation. I paid 1K to have insulation upgraded to R-49 of blown insulation. It looks like they put in closer to 2 ft. I also replaced the non functional attic vent with a gable fan.
Now my 10 year old AC can cool down to 70F when outside's in the 90s.
