Vintage Air vs Classic Auto Air

Yes which model do you have?

Temperature coming out of the vents at max AC?

Any more insulation in the car than stock?

Weatherstripping in good shape and sealing properly?

How many extra holes in your firewall?

Air conditioning doesn't make cold air, it removes heat. If more heat keeps coming in it can't keep up, no unit can.

Ok it is a early gen 2
do not remember temp but the temp differential about was about a 20 degree drop "which is really what you are looking at not just temp"
Just the stock insulation
weather strip and sealing new and good
no holes

I know how AC works but volume comes into play also or else a 1 ton home unit could cool a 5000sf home. There was a thread about the same issue about a year ago.

20* temperature differential isn't enough, I look for 30* and usually do better than that.

I agree about volume, but I can make ice cream in a 34 sedan with a GenII Compac that doesn't move the air or have the coil size that the GenIV has.

Honestly cannot remember the exact temp drop but the AC expert who was checking the system pressures and such was happy with the drop but not the CFM. All I can say all 3 speeds work on the fan with no obstructions and cannot cool the car on a 85 and above day. Freeze the drivers left knee off since the vent is right there but not enough volume. Can't check it now as it won't get above 25 and has been that way for a week ARG! ready for Spring.

3 Speeds? So not a GENIV unit?

Dash vents, the higher the better.

Nope gen II and stock looking car so only the mini vent in the upper dash.

I have heard from two different sources who has installed both systems that classic auto air cools better than the VA setup!!
