We first called Brian 12/29/09 he said he put 20 pounds of R-22 in our system and ther was no leak. By 3/16/09 the a/c was blowing hot again. He pumped a leaking system full of freon again and said he didnt thinkit would last. 3/30/09 we called him again because we had no a/c. He said he would put more freon in and would have to fix later. We never heard back and on 4/2/09 still no a/c. I asked him if he could fix it or not. He told me "F*** YOU!" and hung up on me.
