    Fuel Type ? To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
    Natural Gas
    Vent Type ? Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
    Chimney Vent
    Modulating/Staging ? Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More
    Single Stage
    Blower Type ? Blower type describes the motor that powers the fan in the unit. PSC multi-speed is the standard motor that operates with pre-set fan speed levels. ECM multi-speed are more efficient but still operate with pre-set fan speeds. Finally, ECM variable-speed motors are also energy efficient and automatically adjust to changing system conditions.
    PSC Multi-Speed
    Orientation ? Orientation describes the direction that air will flow through a piece of equipment. (e.g. air will flow horizontally through a "Horizontal" unit heater.) Most equipment will only function properly if installed in the proper orientation.

      Can you lay it down an put it by the ceiling? I want to put it my shop.
      Jamie 
      from Missouri 
      August 23, 2016
      Answer
      Goomdan's GMS-Series furnaces are approved for horizontal installation on either the right or left side. They can also be suspended using 3/8" threaded rod and 2"x2"x3/8" angle iron. Further details on horizontal installation and suspension can be found on pages 9 and 10 of the installation manual

      Can this unit be used in California?
      Francisco 
      from California 
      December 28, 2015
      Answer
      Goodman makes special Low NOx models for use in California and other areas that limit nitrous oxide emissions. These models can be easily found and identified because that have an 'X' instead of an 'N' at the end of the model number. All of the high-efficiency models (AFUE >= 90%), are compliant with these emissions regulations.

      I have a Carrier furnace at the moment. How difficult would it be to install the Goodman furnace in its place since I already have all the duct work in place for the Carrier?
      Timothy 
      from Idaho 
      December 04, 2015
      Answer
      As long as the cabinet dimensions are the same, the job is pretty straightforward. There will likely be a few gas piping and electrical hookup modifications, but these are usually not much work for a professional installer. You'll want to match the width, depth, and height to your existing unit as closely as possible.

      Keep in mind that you should not sacrifice proper output to match physical dimensions -- making adjustments to ductwork is preferable to installing a mis-sized unit.
