08 H2 AirCon Problems

[TedW]

Hi guys,

Bona fides first, 130k on an 03 H2. Traded it in on an 08 about 8 mos ago. 14K on the new one only 8mos old. I'm in CT, so one can expect warm, humid summers. Original compressor failed and was replaced 2 weeks ago. After replacement, all went well for 3-4 days til we hit 85-90 dgf temps w/70%rh.

At that point the a/c could not keep up. Using 2 different temp measuring devices, IR and contact, I tested the air output of my H2 against my wifes 05 3/4 ton Suburban side by side. My a/c was pushing air out at 18mph at 70dg! My wifes truck with 43k miles was pushing air with SAME settings at 25mph 42dgs!

Local dealer, my opinion the best in CT, is now telling me my system is w/in spec. Yet, they are replacing the compressor again! Techie doing the service called me and said (sorry for the direct quote) "the 08 a/c's "suck"". Spoke later to the service manager who said "???, we haven't seen many problems)".
He did not know the tech had called.

I can only see this escalaling into a "P...ing contest". All I know is that paying as much as I did for this truck, I expect it to have a/c. Right now, for work I cannot take a client in the truck with me. W/an outside temp of 90, it is down right warm in the truck. I also regularly haul 5000lbs trailer, can't wait to do that when its warm!

Anyone got any thoughts or comments? 'cause I'm going to have to push this to a new level if the 2nd replacement compressor doesn't solve the issue.

Have a Hummer of a day!
