Will see...

A little disappointed in the outlet temps. I checked my temperature and direction HVAC doors and everything seems to be working. I'd guess the gaskets are toast after 53 years. So probably some leaks on the air intake and exhaust. Service manual says a 4 season GM system should get 40's Fahrenheit at 90-100f. Something isn't quite right.

I can say the condenser is working well at keeping pressures low. The evaporator is putting off a lot of condensation. That cold just isn't making it efficiently to the cabin. Leaks, right?
