Hey Hat,
There are a few DIY things to check/repair on the 964T A/C that will make it a little more efficient.
Drop the valence under the condenser and remove the road debris that gets trapped between the body and the condenser back side. Get a brush on your shop vac and vacuum the coils while your in there. Also, make sure that the seal between the condenser and the front bumper cover hasn't disintegrated.
Make sure that all your damper motors are working properly so that your not putting cold air on the windshield or the floor.
The last item is the center vent. There is a seal between the vent assembly and the duct coming from the climate control fan/damper module in the trunk that also disintegrates and allows cold air to partially bypass the vent assembly. To check/renew the seal you will have to remove the dash pad but that's a 10 minute job.
Enjoy.
