Thats the question. I have seen several systems leak and the common denominator (i'm sure there's others) seems to be the foam. Has anyone else experienced this and have ideas that may increase the life of the systems?
Heres my list and assessment and questions:
Fresh air intake- this is a must anyway to prevent stale air. Should this be mechanical or simply a duct run to the outside. or should there be an air exchange inside the attic to vent it?
Coil cleaning- Should it be done more often than once a year for a period of time after the house is completed or insulated. Is there a solution that neutralizes this perceived off gas corrosion?
Is all of the above a farce and the reason coils leak is recycled copper is softer and more susceptible to corrosion...and we can go off on a tangent and say the green house gasses and global warming are causing the salinity of the oceans to be a higher concentration and thats what causes leaks....as well as gas prices to increase (jk)
Thanks in advance for the assistance,
