The installation of a more AC for my Hummer is a must. Being that it is a wagon, and being a 93, the A/C is in now way enough for the Texas Heat. With Texas being in the upper 90's and humidity so high, you need all the A/C power you can get. The optional A/C unit that is installed may work up north if you are lucky and I am sure it was never tested before the sold it as an option to the public in any kinda hot climate.

It was bad enough with having to take this truck back to the shop every 4 weeks to have Ron Carter "Fix it". It cooled a little, but with in four weeks, no more cool A/C air. It was not until they replaced just about most of the A/C equipment that it stopped leaking. Then when they had to replace the engine, they did not even recharge the A/C unit. Once they did, it leaked with in a week. They just do not know how to do a job right.

So took it to a local A/C shop (Any Make Auto Air) and they fixed the leak first time. I had asked the A/C shop what they improve on the A/C system. No Problem! They ordered a "Aux.Expansion coil & Blower" and it will be installed in the same place as the Aux. A/C unit that the factory or dealership adds. Below are a few photos before installation.

One of the other nice items about the new aux. a/c unit is that it will remove the 4 hoses that are 40-48 inches long before getting to the vents. This will increase the air flow to the front vents that is needed. The factory installed A/C unit back in 93 really was under sized for a wagon.

Dealer installed unit will cost about $1500 -$1600 for just the equipment, labor extra.  Mine was about $500, and another $200 for the final connections and charging it.
