I just upgraded my rig with a new A/C compressor from Carrier Corp, and it's made all the difference in my cross-country drives. I got it from here: oem Carrier 110v (https://firsttruckparts.com/products/55-810-03k-genuine-carrier-corp%C2%AE-a-c-compressor-110v) . The 110V unit was an ideal fit, and installation was a breeze. Now, I'm riding in comfort, no matter the temperature outside, which is a huge plus in my book.
