What's included

Winter doldrums got you down? Or maybe you're depressed that your old furnace barely does the job while costing you an arm and a leg. Solve both problems with a Goodman GMH8 Series Two-Stage Gas Furnace. Built around a heavy-duty tubular heat exchanger and two-stage convertible gas valve, the GMH8 can deliver up to 80% AFUE performance with a low continuous fan speed for quieter air circulation, real warranty support, and multiple installation options.

Goodman delivers more than simple brand recognition with its superior products. This trusted and reliable company brings you some of the industry's top performing and economic products. Plus, Goodman products are made in the USA, and that includes the GMH18 gas furnace.

The 140k BTU 80% AFUE Multi Speed 2 Stage Goodman Gas Furnace - Upflow/Horizontal - 24.5" Cabinet is created with a heavy-duty steel shell painted with a powder paint finish to last. The heat exchanger is insulated to reduce the amount of heat lost from the unit for less than 2% air leakage. This combined with many of the other innovative features mean that you will keep more money in your pocket. Plus, this unit is known for its nearly noiseless sound level even when running at full capacity. For an added bonus, you can easily connect a humidifier to this unit. Simply connect that part to the low-voltage terminal on the easy-to-operate control board.

Goodman is so confident in this furnace that they provide each unit with serious, long term parts warranty protection. To extend that protection further, go online after purchase and register your unit within 60 days of installation. If you are unable to do so, call us and we will help.
