2002 Honda Civic AC Compressor replaced - still not cool en

My AC started blowing warm. Took it to the mechanic and although they couldn't find it right away, they thought I might have a slow leak so they charged it and put in some dye. 3 weeks later, blowing warm again. This time they said my compressor needed to be replaced, so I had them do it. Picked up my car and drove for 45 minutes with AC on MAX in 75 degree weather and it never got particularly cool - it felt better outside my car. To my way of thinking I should have been freezing by then, so I took it back. They said they checked it out again, evacuated and recharged it - claimed they drove it and measured temps in the 30's. Again, I had the same issues. For the record I am very sensitive to cold and am cold at 70 degrees due to a thyroid problem and I have not even been slightly cool in this car since the repair. I can rest my hand on the vent the whole time and it doesn't get anywhere close to where I can't stand it but they claim the "cool" drove them out of the car. Next, I took it to a Honda dealer who said the previous mechanic had overcharged the system so they evacuated and recharged. They said they drove for 15 miles and recorded temp of 46 - of course, the day they worked on it, it was 60 degrees outside. For me, it is slightly cooler, but stilll not cold. Drove 18 miles from work yesterday with temp of 85 outside and again it never really got very cool and what cool there was took almost the entire ride to attain. My AC was always great and I used to be too cool very quickly, like 5 or 10 minutes. My husband has a Dodge Caravan and that thing is so cold within 5 minutes that I can't stand it and his car has the original compressor. Is there something else that could be wrong with my Civic. At this point, I have paid $2000 between both mechanic shops and with a long hot Maryland summer ahead, I really need my AC to work as it should.
