My 2011 was OK until I did the resistor mod. Now it is definitely better. I did not go as far as some did so I have more safety margin. If the evap gets too cold it freezes the water on it and the ice blocks the passageways and it will not blow cool air. That can cause liquid refrigerant to flow back to the compressor killing it. So be careful.

My thermometer has little bitty marks so it was hard to give you a figure but it is a least 3 or 4 degrees cooler after insulating the suction side of mine. I used the non slit 5/8"x1/2" rubatex AC guys used and slit it with a razor blade.

Did this yesterday after reading . I bought the self adhering rubber 1/2 inch hose from Lowes ($5.00 for the 6 ft. piece). I wrapped the lower section of the low side tube that protrudes from firewall out about 2 ft, I also wrapped the section above the factory insulation that comes out near front of engine to the connector junction of that tube. I left about a good foot of tubing exposed where the service port is & furthest away from engine. I wanted some exposed pipe so it wouldn't cause a sludge situation that was mentioned in the earlier post. Results were noticed right away. I am getting a 3 degrees cooler temp than previous reading yesterday at MAX cool setting. I was reading 40Deg yesterday in similar conditions (85 air temp/high humidity), today in similar climate it was cycling between 37-40 degrees. I did feel the difference.
This is an excellent idea that works for so little $

I did the pot mod last week. I am now 33F at the vent. (85ish outside.) Truck is like a dang meat locker

Good choice, do you know what you set it at? Yes, wrapping will not bring the results necessary, like the hack does.

Do you have a link or a SKU of what you bought?

Living in TX, I've NEVER had an air conditioner that really could keep up on the hottest days. Going on business to Las Vagas and Phoenix plenty of times, plenty of different rental cars, when it's hot - you'll never overcome all of that in a normal production car.


So, today, rather than waiting and checking temperatures, I bought the goodies to insulate my 2013's A/C lines like this. As for the other mod, installing the pot on the cable, I'll hold off for now...


Yesterday, I had the whole cab tinted with a ceramic tint that cuts out most of the IR as well as basically all of the UV. Driving home, I was amazed at the difference already. $250 was not cheap, but amortized out, it should be well worth it - especially with the lifetime warranty.

Your on the right track, but myself and others can tell you, if your ac is cycling in the 44-48 range, it isn't ever going to get cold in the cab with temps over 90, even with tint! At least not in Houston!


In other words, why do other ford cars work fine without all of the hacks and tint?

Houston is an extreme case. Hot and humid. If it can cool you in Houston, anywhere else is a piece of cake. Or at lease easier.

Problem is, at 44-48 cycling, it won't. I know! My wife's Edge will freeze you out and she has the full moon roof. She keeps hers on 73. Cycles at 36 to 38.
