    Advanced 2-Stage Heating for Enhanced Comfort: Unlike single-stage furnaces that operate at full capacity all the time, this 2-stage system adjusts its heating output based on demand. During milder weather, it runs at a lower stage, consuming less energy while maintaining even temperatures. When outdoor temperatures drop significantly, it automatically switches to full power to keep your home warm and comfortable.
