I recently put in a new HVAC system last fall and in December I replaced my old roof (yeah, it's a fixer upper). The HVAC tech came out this week to make sure the AC is ready for spring and found the unit low in freon. Turns out he found a hole in the refrigerant line and appears the roofers punctured it with a nail. I contacted the roofer and he said it sounds like the refrigerant line was took close to the roof/sheathing and this is against local code. Hence, he said he is not responsible but will come out and take a look to confirm. My AC guy is pointing the finger at the roofer. Let me say both parties have been proffessional and are reputable. So I am not looking to bash either. I just don't think I should be responsible for the repairs and would like your professional opinions. I have pictures of the line indicating proximity to the roof...just got to figure out if and how I can get them posted for you guys Thanks for any advice you can provide.
