I'm going to be clear. I my original post I was not throwing a punch at anyone on this site.
I think we all here have seen our far share of people getting shafted. Alot of them come not even knowing they did get the tail end of the deal.
Because I care for others... it's frustrating to see someone come with issues that can be sorted out with ease- especially since Google and youtube have most info anyone working on anything will need.
Reading the OP I hear the same thing everyday. Last tech adjusted the pressures.
Basically he took/ let some gas out to get the head pressure down.
Like jsdirt said look at and clean the condenser coil. It is located in front of the radiator. In lue of going back to the tech you can purchase a Water Saber . This connects to your garden hose and will flush out the radiator, condenser coil, trans cooler and you can use it to clean any place on a vehicle you can not reach.
