Question:
My AC unit is blowing cool air, but my room temperature is not getting cooler… The blower seems to be working fine, however there is some condensation on the cooper line inside the house.

Your thermostat is working properly if it cycles the machine off and on around 1-2 degrees of the set point.
As stated earlier, measure the temperature at the thermostat with another thermometer, if the set point and the thermometer match to within approx 2 degrees your thermostat is working fine. If not then further investigation is necessary.
It could be that the machine cannot handle the heat load and the thermostat never gets a chance to cycle the machine off, keep this in mind before condemning the t/stat.
After all I’ve said so far it is probably likely that the A/C unit is struggling with the heat load but the only way to find out is to call a reputable and experienced /qualified technician and get them to check it out. At least then you will know one way or another.
