When you're choosing a gas furnace, the first decision is often between a brand-new unit and an open-box one. In this comparison, both options are single-stage Goodman furnaces with 80% AFUE and 80,000 BTU output, but the listings differ in condition and price. The new Goodman GM9S800804BN is listed at $1,049.00, while the Goodman 80% 80,000 BTU Single Stage Gas Furnace (Scratch & Dent) is listed at $1,416.20. That price spread means the open-box unit costs more than the new one, which makes the choice about more than just condition.
Quick Verdict
If you want a new furnace and the lower listed price, the GM9S800804BN is the straightforward pick. If you need a higher listed airflow and are comfortable with an open-box scratch & dent unit, the other Goodman is worth considering, even though it carries the higher listed price.

Where Each Wins
- Goodman GM9S800804BN: Wins on condition and price. It's the new unit, and it's listed at the lower price in this head-to-head.
- Goodman 80% 80,000 BTU (Scratch & Dent): Wins on listed airflow. It shows a higher CFM figure than the GM9S800804BN's rating.
Product Notes
#### Goodman GM9S800804BN 80K BTU Gas Furnace
The GM9S800804BN is the new unit in this pairing and matches the other on core specs like efficiency, heating capacity, and blower type. The listing describes an upflow/horizontal configuration with natural gas or propane capability and a listed airflow rating that is the lower of the two. Its biggest advantage is the listed price, which is the lower of the two in this comparison. If you want a specific model number and a new furnace, this is the one to build around. The trade-off is that its airflow rating is lower than the scratch & dent unit's higher airflow figure, so if your ductwork needs more airflow, the other listing may suit you better.
#### Goodman 80% 80,000 BTU Single Stage Gas Furnace - Scratch & Dent
This listing is the open-box scratch & dent version of a Goodman 80% 80,000 BTU single-stage furnace. The listing shows 1760 CFM airflow and the same efficiency as the new unit. Where it stands out is that 1760 CFM airflow figure, which exceeds the new unit's 1600 CFM rating. If your system requires that higher airflow, this unit could be the better fit. The catch is the condition and the price: it's an open-box scratch & dent unit listed at the higher end of the price range shown above. You'd be paying more for a unit that has been opened and shows cosmetic imperfections from the scratch & dent designation. It's a sensible choice only if the higher airflow is essential and the open-box condition is acceptable.
Final Choice by Use Case
Choose the Goodman GM9S800804BN if you want a brand-new furnace with a specific model number and a lower listed price. Choose the Goodman 80% 80,000 BTU Single Stage Gas Furnace - Scratch & Dent only if you need the higher listed airflow and are willing to pay more for an open-box unit. For most installations, the new GM9S800804BN delivers the same efficiency and heating capacity at a lower listed price, making it the stronger pick for typical furnace replacements.
