Our modulating gas valve helps the Infinity 98 efficiency deliver the ideal heating capacity for current conditions when the Infinity control is included with your system.
By continuously adjusting heating output up and down through multiple stages in 1% increments, this furnace precisely matches your comfort needs. Most other furnaces can provide only one or two stages of heating and must start a new heating cycle to reduce heating capacity as conditions changes.
The variable-speed inducer motor precisely controls air intake within the combustion system to ensure increased gas efficiency for comfortable heating performance.
Heat exchangers are vital to your comfort and the efficiency of your furnace because they extract heat from the gas used. The Infinity 98 uses two heat exchanger to optimize efficiency. Our primary heat exchanger does most of the work. Then, our secondary heat exchanger pulls additional heating energy from operation to maximize efficiency and provide soothing comfort.
By combining the Infinity Control with Infinity the Infinity control board in furnace itself, Carrier put maximum control at your fingertips.
The Carrier Infinity 98 gas furnace is one of the quietest gas furnace you can buy.
