This unit was only a year old. Panel was missing screw and flapping in wind. The compressor was fragged, probably from the constant jogging when terminals arced.
As for the warranty ??, We did not install it, and the unit was not registered by a contractor so supplier said NO.
Nordyne HP, comes with 6 inch bugs(pre-crimped, stranded wire). WE, nut them to solid stat wire then connect to terminals. May have been a goodman, I can't remember.
