AC air not cold after work done

I have a 2011 Honda Civic LX 1.8l. I just had a new compressor, evaporator, expansion valve, and dryer put in. The air coming out still isn't ice cold, only cool about 65 degrees. I blew out the lines before putting in those components. It's about 95 degrees Fahrenheit here and the high side was at around 180 and low-side about 38. Compressor kicks on, no leaks. It takes about 2.7 ounces of oil and the new compressor had 2.5 ounces so i only put in about a quarter of an ounce. The refrigerant capacity also is .98 lbs of R134f. It has .94 lbs. Is there something I'm missing here?

Is the fan coming on? Those pressures seem a tad on the low end especially for 95°f, but I do AC more by the seat of my pants.

Yup Blower fan blowing no problem there. We were in the shade too on that day so it might have been like 90 degrees haha

I meant the condenser fan. Sorry, should have been more clear.

I would start looking at the blend door and motor. Some vehicles have a recalibration process. its not the fan. if the fan was not working properly the pressures would be high, yours are ok. maybe even a little low.

If I get heat coming out when i turn the temperature knob, would that still be a blend door problem?

You're 100% correct. A non functioning fan would result in higher pressure. 

The pressure seems a bit low to me as well. I would be tempted to give it another shot of 134a...
I assume that after the repairs you pulled a good vacuum on the system before charging it up?

Yes i have a Robinair machine. That automatically pulls a vacuum on the system.
