Question Newbie here. Requesting support for eg4 12ton hybrid mini spliit.

Forgive me if I am on the incorrect thread but tried to post yesterday without success.  My 16 month old 12K stopped cooling a few days ago.  The following morning I found the suction fitting/nut on the line set had cracked in half and the line pulled away.

I sent an email to Signature Solar but no response yet.  

I'm just looking for a path to repair.   Is there a warranty?  Hopefully not an Oklahoma warranty.  Would I work with Signature Solar or EG4.

Are there local techs who can work on these systems.

Just looking for a starting point.

Thanks in advance.
