1. Refrigerant Pressures: LOW = 45 Psi, HIGH = a bit more than 200 psi in idle.
2. Pressures below that, the A/C doesnt cool at all.
3. Dryer filter new.
4. When the car is Idle no cooling. (even in cold days)
5. When engine is at 2K RPM or above, cool a little. (cool well in cold days)
6. With the car moving around 30 MPH or above, cool a little better.(cool very well in cold days)
7. All above if I turn my A/C on with the car in low temperature and NEXT I go to a hot, sunny place.
8. If I turn my a/c on after the car was parket in sun, no cooling for a long time.
9. THe compressor clutch is engaged. The system in ON. THe car is less powerful (means the A/C compressor is ON).
10. Idle RPM from 700 to 800.
11. I put 65 psi of refrigerant... started to cool a little better, but weak yet. With 65 psi I cant accel... THe compressor goes off.
12. With 65 psi I can feel the alumunium conector freezing and with water...
13. I turned the pressure back to 45 psi. If not, the compressor would go off every second.
I'm sure that the system is ON. When I push the button A/C, the green light appears, I can hear a sound of clutch engaging, I go to the engine compartment and I can see the clutch spinning, and I can feel in cold days that the system works in IDLE, but very weak. So when I have a hotter day, no cooling at all at IDLE. I'll tight up my belt this weekend as was suggested to me by an expert guy. But, beside that, Has anyone else some idea of the problem it could be? Thanks!

Just answered at the 95 Civic post on second page. Readers - techs go to the last few posts at this thread to get the jist of this which is now a 93 and not a 95 Civic.

Quick summary: The correct charge is unknown in this car and should start the charge from scratch and this system will self destruct if not tended to!!
