I just had someone replace my old leaking AC compressor on the 98 Explorer. It doesn't blow the air as real icy cold as before. Any idea?

Did that someone not vacuum and properly recharge the system to the correct capacity?

Are you certain it's not still seeping out somewhere else?

It could also be perceptional.

I've done A/C work on my own vehicles and sometimes thought something was still wrong. Buy a small pocket thermometer and insert it into a center dash outlet. Let the system run and, while driving, you'll hopefully notice a much cooler reading. Typically ten or more degrees cooler than ambient air temps.

Is there anything tunable under the hood if all the vacuum & recharge was done properly?

Nope. If the system was properly charged and the system is cycling, there's little to be done.

It's a good idea to also replace the dryer/receiver and Thermostatic Expansion Valve (TXV), when you have major air conditioner work done.
