The Goodman GMH951155DX is a 5 ton two-stage gas valve, multi-speed gas furnace. This means you get comfort and cost savings from this energy saving furnace. A two-stage furnace has a low fire and a high fire gas valve, allowing just enough gas to heat your home to the desired temperature, while you set the multi-speed motor to operate at the level most comfortable for you and your home.

In fact, this furnace has a rating of up to 95% AFUE (Annual Fuel Utilization Efficiency), meaning that 95 cents of every dollar of heating energy expense heats your home, compared to some older central heating systems which are rated at only 80% AFUE. In addition, this furnace has a variety of features to keep you comfortable all year long including an electronic control board with self-diagnostics and it is humidifier and electronic air cleaner ready.
