Plus, you can enjoy more consistent temperatures, quieter operation and money-saving energy efficiency all year long. It's exactly the kind of performance you've learned to expect from Carrier, your indoor weather experts. The WeatherMaker two-speed gas furnace delivers consistent, efficient indoor weather. The WeatherMaker operates at low heating capacity up to ninety percent of the time. In low capacity, the furnace is quieter and much more energy efficient.
Standard furnaces can only operate at full capacity, which increases noise and energy usage.
