Is this furnace good for a large house?

Yes. With 100,000 BTU input and 80,000 BTU output, it is sized for large homes. A load calculation should confirm the size before buying.

Two-stage versus single-stage: what changes?

The two-stage valve runs mostly on low fire for longer, steadier heat and less temperature swing, and switches to high fire on cold days. Single-stage furnaces only run full blast.

Does it need special venting?

No. At 80% AFUE it vents through a standard metal flue, not PVC. That makes it a simpler swap for an existing 80% furnace.

What blower motor does it use?

A nine-speed ECM blower. It moves up to 1,735 CFM at 0.5 in. ESP, enough for a large duct system and add-on cooling.

Can I add air conditioning?

Yes, an evaporator coil and outdoor unit can be paired with it. The ECM blower and airflow capacity support a matching coil.

The furnace cabinet and blower assembly. The thermostat, venting, gas piping and any cooling coil are supplied separately by the installer.

Our take on the Wrangler Gas Furnace WR-GR9T801004CN

The Wrangler WR-GR9T801004CN is an 80% AFUE, two-stage gas furnace rated at 100,000 BTU input and 80,000 BTU output. Its two-stage gas valve runs at low or high fire, and a nine-speed ECM blower spreads airflow quietly across a large home. It is an upflow/horizontal unit in a 21-inch cabinet, so it fits a basement, closet or attic install. Against single-stage 80% furnaces it offers steadier heat and quieter blower operation; against 90%+ condensing models it gives up efficiency and needs no PVC venting or condensate drain.
