80,000 BTU Heating Capacity

80% Efficiency Rating

Operating at 80% AFUE, this Goodman furnace converts 80% of its fuel into usable home heating, venting only 20% through the flue. As with all 80% AFUE models, the GRVT800805DN requires metal flue venting. Higher-efficiency furnaces (90%+ AFUE) instead use PVC venting systems.

Important: The Goodman GRVT800805DN is not Low NOx or Ultra-Low NOx compliant and cannot be installed in counties or regions within California that require stricter emission standards. Please verify compliance with local air quality regulations before purchase.

Two-Stage Variable Speed Performance

This Goodman furnace utilizes a two-stage gas valve and a variable speed blower motor to deliver precise airflow control and consistent heating comfort.
