Value and Warmth
Are Built In

95% AFUE
High-efficiency Ameristar furnaces provide exceptional value, and can be used with natural gas or converted to propane. In addition, the furnace also works with your outdoor system to circulate cool air in summer, helping you stay comfortable all year long.

Add a programmable thermostat

A programmable thermostat gives you complete control over your Ameristar system so you can maintain pleasant temperatures within your budget.

Ask your installer for available options.

  • Highly efficient performance at up to 95% AFUE
  • Flexible heating with natural gas or propane
  • Durable, aluminized steel heat exchangers conduct heat with greater efficiency than other options
  • Galvanized steel cabinets resist corrosion
  • Adaptable designs ensure the right fit for your home
  • 10-year registered limited warranty, 20-year limited heat exchanger warranty;* 5-year base limited warranty, 20-year limited heat exchanger warranty
