Cool & not cold A/C problem solved

Recently, with the 90+ temperatures in New Jersey, it became obvious that the A/C in our 1994 9000 Aero (75,000 miles) was putting out cool, but not cold, air. Took the car to my indie and he quickly diagnosed the problem being due to excessive high side pressure in the system, being caused by a clogged expansion valve and receiver dryer. Replaced those parts, recharged the system and the A/C output temperature improved by almost 10 degrees. So for those of you whose A/C performance has begun to deteriorate somewhat, keep in mind that it is apparently fairly common that the problem may be caused by a clogged expansion valve and receiver dryer, and not necessarily a leak in the system.
