Liquid line restriction

Hi All,

My unit does not seem to be cooling. Had someone come take a look at it, and here are the tech's notes from troubleshooting:

Client indicates system does not cool. When checking the system over the pressures were 146 low and 234 high super heat was 38 and subcooling was 0. The liquid line was sweating at the evaporator coil . Checked temperatures across the filter drier and got a 3 degree difference across it. Also have a 10 degree temperature difference from the liquid line at the evaporator coil and the liquid line at the condenser. Need to quote client to replace filter drier, and to also check the capullary tube to. The filter drier is built into the the liquid line in side the condensing unit.

Based on this, he indicated that he was pretty sure that the filter dryer is clogged up because there should not be any temp difference across the filter dryer.

Now my question is, could the filter dryer be restricting flow or could it be the liquid line from the condenser to the evaporator?

Follow up question is that the filter dryer is inside the condensing unit. It can be gotten to it easily, but can it be replaced? I don't want to buy a new condensing unit just to address a clogged up filter dryer.
