Air con need Rovacom "All about 4x4"

I'm having Air Con problems. Have stripped it to the HEVAC but before I go further I need to get it to a Rovacom to try and establish the fault. Not too far from me is a company called "All About 4x4" near Redditch. They have a Rovacom and offer to hook up and report for about £32 which ain't so bad. Anybody know them? - Thanks

Sounds reasonable enough to hook up and get a report, you don't have to have any further work done there if you don't want to.
