Anyone improve their A/C???

[BigWheel]

Driving Hot Rod in 95+ degree heat gives new meaning to the name "Hot Rod". This fall I converted the A/C to 134 and got everything running. When the temp is in the 80's it cools just fine but if in the 90's, with direct sun light, it's a warm ride to say the least. Any ideas on improving the efficiency of the A/C???

Its been hot here too... and keeping the shade in the window all day sure helps a lot...

i have a little probe temperature thing in my vent, and even in 100 degree weather it comes out between 45 and 50 degrees within 3-5 minutes.... i also have it converted to 134.. maybe you need a charge??
i have a buddy who has an A/C place, and 134 takes 1.2 lbs.. good luck and stay cool.

I tinted the back side windows and the back glass and that helped.

Yeah, second that!
Even without AC, tinting the rear window helps.
Agree that unit could need charging, did you replace the drier when you converted to 134A?

I have the side-back windows tinted but I need to do the hatch and side-front as well. The A/C is blowing cold air but it just can't seem to overcome the heat. Even in my F-150, which was just charged, it takes a few minutes but it will finally cool the whole truck but not the Festy. The temp coming out of the vents is about 45 so it just doesn't seem to be putting enough of the cold stuff out to help.

If your cranking out 45 degree air then nothing wrong with the unit.
Your just gaining more heat than the unit can over come.
Check that you have the on board controls set to recirculate.
Better to try and cool 70 degree air than 90 degree air!

Need to have the tint to keep some of the hot out and the cool in...:p

12 cools better than 134 anyday

[mechanicaldj]

try getting the condenser fan from an automatic with factory a/c and some dealer a/c systems too

it will greatly reduce your high side head pressure
which R-134a produces very fast

or


look at installing FREEZE 12
does a better job at cooling than 134a

[ejp2fast]

yep, set to recirculate, and vent on top only... and on the highest fan speed... if you have 45 coming out, i don't think you can get much better than that.

I just finished my ac repair down here in fl and i have the same problem i have limo tint all the way around but 90deg or higher and a black car bad color i chose , it just cant keep up with the heat its a lot cooler than windows open though . at night or in the 80s its freezing im going to get my windshield tinted some as well like 30% so much heat and sun comes through it i can probably shave 3 deg off by doing this ! good luck but atleast we have some ac

I really appreciate everyone's input on this. I'll tint the windows and we'll go from there. My Festy's A/C reminds me of the Heat Pump in the south. Once you get over 93 it basically has to run non-stop to keep up. Just part of living in the deep south I guess. Thanks guys!!!!
