Had a brand new Philco ac unit installed 2 years ago in my 13 year old home. The AC tech that I use said it was time after yearly visits to my home for freon charges, coil replacements, and other problems. A year after installation the unit frooze up and flooded a part of the second floor.
Called AC tech and he recharged the system and said there was a freon leak. He also added a expensive liquid that he said may or may not seal the freon leak. This was in the fall and I did not use the system for approximately 4 to 5 months. I called AC tech for yearly check up in April 2011. He said everything looked good and again he added a little freon. Came back from vacation in July and guess what we are freezing up again on the second floor.
AC tech came out, added a little freon and stated that he would have to repipe my home because he detected a leak in the wall where the cooper pipe on the outside unit goes into the wall that then goes to the upstairs unit. My questiions are as follows:
Is there any way to detect a leak in the wall other than the leak detector the AC tech used that makes a noise? I do not trust that device.
What happens if the home is repiped and a freon leak still exist? Who would be liable? I want to be absoluely sure that this leak exist as the Tech states.
I am tired of dealing with AC issues, as you can probably tell, It is like pouring money down the drain. I want my system to work as it should and not have to worry year to year about freeze ups, soaked rugs, and freon charges. Thanking you in advance.
