Upon arrival customer told me the ac unit was not cooling or heating. I turned On the unit in heating and it will kick on and off at the condenser. I put it in cooling and unit ran but low on Freon had to add 2 pounds of 410A. I got the number where it should be in cooling. But it in cooling and the number where equalized. I tried to slam the revising valve back and fourth and it would not move. The revising valve is bad
