Is this furnace worth it over a single-stage model?

If you want steadier heat and a quieter, more efficient blower, the two-stage design is a real step up from a basic single-stage furnace. If you are chasing the lowest fuel use, a condensing 90%+ furnace does better.

What size home does 60,000 BTU input suit?

It delivers 48,000 BTU of output, which generally fits a mid-size home in a moderate climate. A load calculation on your house is the only reliable way to size it.

Does it need a special thermostat?

A two-stage thermostat lets it use both heating stages properly. With a single-stage thermostat it can still run, but you lose some of the staging benefit.

Can it be installed horizontally?

Yes. The cabinet is set up for upflow or horizontal airflow, so it fits basements, closets and attic layouts that suit either orientation.

The furnace itself. Venting, the thermostat, the coil and the rest of the system are separate parts chosen for your install.

How does it compare with Goodman's condensing furnaces?

This is an 80% AFUE unit with a two-stage valve and ECM blower. Goodman's condensing models reach higher efficiency but cost more and need different venting.

About the Goodman GR9T800603BX Gas Furnace

The Goodman GR9T800603BX is a two-stage, gas-fired forced-air furnace with a 60,000 BTU input rating and a rated output of 48,000 BTU. It has an 80% AFUE rating, so it converts 80% of its fuel input into usable indoor heat. It is designed for upflow or horizontal airflow, with horizontal-left and horizontal-right options.

A two-stage gas valve lets the furnace run at a lower heating stage when demand is modest and switch to full capacity when more heat is needed. This reduces the frequent on-and-off cycling of single-stage equipment. The nine-speed ECM circulator blower has selectable speeds, so airflow can be matched to compatible indoor coils and outdoor equipment.

The heat exchanger is heavy-duty aluminized-steel tubing. The furnace also has a silicon-nitride hot-surface igniter, a self-diagnostic control board, a low-NOx burner configuration and a quiet induced-draft blower. Gas and electrical connections can be made on the left or right side. The control system is R-32-ready for compatible cooling equipment.
