Weathermaker 8000 Two-Speed

The WeatherMaker 8000 Two-Speed offers more consistent indoor weather and energy efficiency than typical single-speed furnaces.  Achieving 80% AFUE (Annual Fuel Utilization Efficiency), this furnace uses intelligent controls to automatically select the best output so you can economically maintain your desired comfort level.

Operating at a slower, more consistent level 90% of the time, the WeatherMaker 8000 Two-Speed increases air circulation, energy savings, and overall comfort, at reduced noise levels.  The lower heating stage creates quieter, longer heating cycles that increase the airflow throughout your home for more consistent temperatures in every room.  This increased airflow also improves your indoor air quality because more air is circulated through your filters.
