Single & Variable Furnace | A951X | A952V

The Ameristar A951X and A952V are high-efficiency gas furnaces that deliver reliable warmth at an affordable price point. With up to 96% AFUE, ENERGY STAR certification, and a compact 34" cabinet height, they fit tight spaces without sacrificing performance. The A951X features a constant torque ECM motor for efficient, consistent airflow, while the A952V steps up to a variable-speed ECM blower and two-stage gas valve for quieter, more even comfort. Both are backed by stainless steel heat exchangers and a 10-year registered parts and 20-year heat exchanger warranty.
