Summer is nearly here and I took the car to maintenance shop for AC Freon recharge and learned that the AC compressor was on its a way out, being the car is 20 years old. Mechanic replaced the compressor with the new one, hooked it all up and got really nice cold air 44F degrees coming out of the vent on passenger side but the drivers side vents only shows 10-12 degrees higher than the passenger side vents. Blend actuators doors are working fine. What could this be the problem? Is it something may be clogged somewhere in the vent pipes and if that so how do I check it?
AC temperature is about 10-12 degrees higher on driver side.

What you're seeing is a classic symptom of a slightly low freon charge. I've seen it before, and adding a little more (a few ounces) helped the problem.
Also, it helps to make sure the condenser in front of the radiator is really clean. There are YouTube videos of using a can of coil cleaner (available at your local hardware / home improvement store) on a car with a working AC that showed lower high side pressures after cleaning, which indicates the cleaner coil was doing a better job of removing heat from the refrigerant.

The condenser should be replaced along with the compressor. ?
But Edwin beat me to it yes you are low on freon.
