Is the low side at 70 lbs or is the temp at the vents 70 degrees? A bit confusing in your question.
The low side should be 25-35. Above that the Freon is flooding the EVAP and it will not cool properly.
The high side is way high. It should be two times out air temperature plus 15%.
How much Freon did he install?
