The DECTRA (GARN) GARN WHS-1000H and WHS1000V holds EPA certification number n/a but is no longer on the current certified list — it is previously certified, which usually means the model is out of production. Already-installed units are unaffected by that status in most jurisdictions.

The DECTRA (GARN) GARN WHS-1000H and WHS1000V's certified efficiency is 77% HHV, which met the credit's ≥75% HHV threshold while it existed.
