The pressures will indicate what component is not working or if you have a blockage, you can google pressure readings interpretation and that gives you possible causes: ie failed expansion valve, etc. If your pressures are good, that means you don't have a leak which is a good thing because replacing an evaporator is a pain in the ass.

Yeah it was done at a UK chain called ATS - they're not known for going the extra mile unless you're luckily enough to get a helpful technician. I've got a replacement interior to fit (mine is grey which I don't like at all) so wanted to rule out the expansion before swapping the interior as I'd heard you had to remove a lot of it anyway to replace the expansion.
