When you need a new gas furnace, the first decision isn't just the brand on the cabinet. It's how much heat your house needs, how efficiently you want that heat produced, and how much you're willing to spend before installation. The four furnaces here cover different spots in the residential gas heating market, from an entry-level 14-inch wide model to a 98% AFUE open-box Rheem. The product notes below highlight what you actually get at each listed price.
Quick take
The lowest-priced listing has a smaller heat output than the rest. The Johnson Controls model costs more but adds stepwise operation. The other new furnace sits in the middle of the price range, and the Rheem R98MV is the top-priced option.

Product notes
17.5-Inch Furnace
This new unit sits at a middle listed price between the entry-level model and the Rheem. The concrete reason to consider it is the combination of a high efficiency rating and a 17.5-inch width in a single-stage design. It's a good fit if you want one of the more efficient new options here without choosing the most expensive listing. The trade-off is the single-stage operation: you won't get the stepped heat delivery of the Johnson Controls model. The 17.5-inch width is also wider than the 14-inch model, so it's worth measuring your installation space before committing.
14-Inch Furnace
If your budget comes first, this is the lowest listed price of the four. It's a new single-stage furnace with a compact 14-inch width. The reason to pick it is the entry price and the smaller footprint, which can be easier to slide into a tight closet or alcove. It also lists a metal exhaust flue requirement. The limitation is that it carries a lower efficiency rating than the higher-end units in this group, and the heat output is the smallest here. That makes it a candidate for smaller heating loads, not for a large house with serious winter demand.
Rheem R98MV Endeavor Prestige
This is the only open-box furnace in the comparison. The listing notes that the unit may show general wear from transit and warehouse storage, and that the box labels have been removed. The reason to consider it is the highest efficiency rating among the four, which matters if you want to reduce fuel consumption over time. It also lists a mid-sized heat output, which is less than the higher-capacity models but more than the entry-level heat output. The limitation is the top listed price and the open-box condition; if you are not comfortable with a display or returned unit, one of the new models may be a better fit.
Johnson Controls TM8V080B12MP12C
This new furnace gives you two-stage operation, which lets the unit run at a lower stage to ease temperature swings before kicking up to full heat. The listed price is only about a hundred dollars above the lowest-priced furnace, and you get an ECM blower and a new unit. The reason to choose it is the two-stage behavior at an approachable price point. The limitation is the efficiency rating, which trails the high-efficiency options in this comparison. If you want improved comfort without making the jump to the top of the price range, this two-stage model is a practical middle ground.
Final recommendation
If your main constraint is budget, the furnace with the lowest listed price is the easiest on the wallet. If you want two-stage operation without jumping to the top of the price range, the Johnson Controls model is the one to look at. If efficiency is the whole game and you can accept an open-box unit, the Rheem is the strongest candidate. And if you want a new furnace with high efficiency without going to the top of the price range, the middle-priced new furnace balances all three.
