80,000 BTU Heating Capacity
With an input of 80,000 BTUs and an output of 64,000 BTUs, the Goodman GRVT800805DN provides powerful, efficient heating for small to medium homes. Its two-stage heating system automatically adjusts output based on temperature demands, reducing energy waste and maintaining optimal indoor comfort.
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.
Compliance Notice
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. The advanced variable speed motor helps maintain balanced temperatures, improves efficiency, and reduces operational noise compared to single-stage models.
Durability and Reliability
