- Is 120,000 BTU right for my house?
- It suits larger homes in cold climates with high heat loss. A load calculation (Manual J) is the only reliable way to size it; an oversized furnace short-cycles and runs less comfortably.
- What AFUE does this furnace have?
- 92% AFUE, so it condenses and vents through PVC pipe rather than a metal flue. That is well above older 80% furnaces but below top-tier modulating models.
- Can it be installed horizontally?
- Yes. It is configured for upflow or horizontal airflow, which lets it fit basements, closets and attic spaces depending on the duct layout.
- Can it run on propane?
- Yes, with an optional propane conversion kit. Natural gas is the default fuel.
- Single-stage or two-stage?
- This is single-stage: it runs at full output or off. Two-stage and modulating furnaces cost more but hold room temperatures steadier and run quieter at low fire.
- What venting does it need?
- Plastic/PVC flue venting, plus a condensate drain for the condensing process. It cannot use a standard metal flue.
