GE 96%, 97% and 98% AFUE condensing gas furnaces for contractors. Choose single-stage, two-stage or modulating burners with constant-torque or variable-speed ECM blowers, in upflow/horizontal and downflow models from 30,000 to 132,000 BTU input. Condensing furnaces vent with plastic pipe and need a condensate drain; follow GE installation instructions. Models ending in R are R-454B compatible with a factory-installed refrigerant detection (RDS) control. Trade accounts only: sign in for your pricing.
