Quick Take
Shopping for a gas furnace is rarely about picking the most expensive option. It is about matching the furnace to the amount of heat your home needs, the efficiency rating you are comfortable with, and the physical space around your existing equipment. This group covers four single-stage gas furnaces: three Goodman listings and one described as a private-brand furnace. One model stands out for a higher efficiency rating, another stands out for more heating input, and the other two share the same capacity class while approaching price and cabinet size differently. Use the price comparison and decision matrix to narrow the field, then read the product notes for the trade-offs.
Listed Price Comparison
The bars show how each listed price compares within the group.
| Model | Listed price | Price bar |
|---|---|---|
| Goodman GM9S960603BN | USD 1,394.10 | |
| Goodman GM9S800804BN | USD 1,049.00 | |
| Goodman GM9S800603AN | USD 799.99 | |
| Private-brand gas furnace | USD 888.00 |
Decision Matrix
The matrix focuses on the specs that matter most for a furnace decision: input capacity, efficiency, blower type, and the one detail that makes each listing distinct.
| Model | BTU input | AFUE | Blower type | Standout detail |
|---|---|---|---|---|
| Goodman GM9S960603BN | 60K | 96% | ECM | Highest AFUE in the group |
| Goodman GM9S800804BN | 80K | 80% | ECM | Highest heating input |
| Goodman GM9S800603AN | 60K | 80% | ECM | Goodman 60K entry point |
| Private-brand 60K furnace | 60K | 80% | ECM | 14-inch width, upflow/horizontal |
Goodman GM9S960603BN: The higher-efficiency Goodman
If efficiency is the first thing on your list, this is the furnace to compare against. It is the only listing in this set with a 96% AFUE rating, which separates it from the other three models. The 60K input capacity puts it in the same general size class as two of the other models, but the higher efficiency rating is what sets it apart. The trade-off is that it stays in that 60K input class, so it cannot match the heating input of the larger Goodman in this group. If your heating load fits a 60K furnace and efficiency is more important than a higher BTU rating, this Goodman is the easy choice.
Goodman GM9S800804BN: The higher-input Goodman
When you need more heat than the standard-capacity models can provide, this Goodman is the one to look at. It has the highest heating input in the group, and the listed blower is rated for a higher CFM than the other three. For a space that needs more output, the extra heating input is the main reason to move up from the smaller-capacity units. The limitation is efficiency: the AFUE rating is lower than the most efficient model in this comparison. The listed price also sits between the other two Goodmans, which makes it a practical middle option on cost as well.
Goodman GM9S800603AN: The entry-point Goodman
The Goodman GM9S800603AN is the most straightforward entry point if you want a Goodman without the higher-priced options in the lineup. It carries the same capacity as the higher-efficiency Goodman above, but with a lower listed price. The main sacrifice is the efficiency rating: it does not match the highest AFUE rating in this group. It also places you in the same capacity class as the private-brand furnace, so the deciding factor between these two comes down to brand preference and the difference in listed price. For a shopper who values the Goodman label and wants to keep the initial outlay lower, this unit makes sense.
The 14-Inch Private-Brand Option
The private-brand furnace is the one to isolate when cabinet width is a constraint. The listing calls out a 14-inch width and an upflow/horizontal orientation, details you do not see in the other three entries. Beyond that, it shares the same capacity and efficiency class as one of the Goodman units, so you are not stepping up in efficiency by choosing it. The limitation is straightforward: this is not a Goodman-brand furnace, and the listing describes it as a private-brand product. If you are comfortable with that and the narrower footprint solves a logistics issue, it is a practical contender. If brand matters to you, the Goodman options give you a more familiar label.
Final Recommendation by Use Case
Start by deciding which constraint is hardest: fuel efficiency, heating input, or cabinet width.
- If your primary goal is the highest AFUE rating, the Goodman GM9S960603BN is the model to choose.
- If you need the most heating input the group offers, the Goodman GM9S800804BN fits that need.
- If you want a Goodman in the same capacity class as the highest-efficiency model but do not need its efficiency rating, the Goodman GM9S800603AN is the entry point.
- If your mechanical room is tight and width matters, the private-brand 14-inch furnace is the model to measure.
