I paid a technician to retype any surfaces that might be leaking air and to clean outside ac. He left and a day later water started leaking through the ceiling from the attic. I tried to reach him and he never returned my calls in my desperation I contacted my dads friend who is a ac tech and paid him to fix the problem. He said the previous guy stepped on my drain pipe and unlabeled it so instead of leaking out it clogged my unit and started dripping in my attic to cause it to go through the sheetrock into my living room.
After he left the next day I started hearing knocking noises in attic.. Its been 2 days and I don't know if this is bad....
I have already paid 2 people and its been expensive already I don't know if that knocking noise is something I can ignore for a while. 4951
