Did he check the capacitor?

Subject: [DIY] Home AC question
Not sure what is wrong. Home AC is not cooling properly. We had the outside compressor changed out last year after a compressor locked due to losing all Freon and honestly it has not cooled good since.
I had a repairman out about a 3 weeks ago Freon was a little low so he topped it off. Unit was back working like last year but still not cooling good. Thermostat on 70 and house would get to 75 to 76 in later afternoon.
Friday called him back as unit was not cooling again. Raining Friday so he came back Saturday. He said it was froze up and low on Freon again. Turned compressor off for 3 to 4 hours. He could not find a leak so added stop leak and topped off Freon.
After stop leak and Freon topped off unit was not cooling at all, house was getting hotter. Went out and looked and low pressure line to compressor was iced over so turned unit off and called again.
He came out again today. Freon was holding pressure so leak is stopped, hopefully. He changed high pressure line filter by compressor as he determined it was restricted.
Unit is still not cooling. Measured air temp at return and it was 80 degrees. Air temp from 2 different vents was 72 degrees. So only 8 degree change. House was at 80 degrees with outside temp around 90 degrees.
Return air filter is recently replaced, 3 weeks ago., and Freon is good.
I have noticed the air from outside condensing unit is not warm and the high pressure line is not warm at all. I confirmed on neighbors unit the air being blown up from outside compressor is slightly warm and the
High pressure line is slightly warm, but min are not. I would figure if compressor was not compressing Freon repairman could tell this on his gages so may be nothing as neighbors unit is about 20 years old.
Not sure where to go from here. Inside evaporator coil is horizontal in the attic, so I cannot check or clean the inside without removing.
Any suggestions for things to check before replacing A coils (evaporator coils)?
