I have a question about an A/C unit installed on it's side in my attic that is leaking. Is stop leak a viable solution?
I have two separate units installed on their side in my attic (2 blowers/evaporator coils with the condensors outside). One has no problems, the other does. I have had "mildew" accumulating in the coil that no one has been able to resolve. I now have coolant leaks. The resolution offered was to replace the unit or try stop leak for $200 w/ no guarantee. The tech tells me units on their side have more issues but the other unit is not problematic. Further, if I elect to replace, access is currently limited to 20" square. The current unit was two pieces & fit through the access but I'm not aware of a replacement unit that will work. Thoughts? Solutions?
