Greenspeed Intelligence is only made possible when you pair the best of our Infinity series products—the modulating Infinity 98 gas furnace or the variable-speed Infinity 20 heat pump**—with the smarts of the Infinity® control. It takes an Infinity system to an even higher level, something we like to call adaptable-speed because it adapts.
Adaptable speed furnaces and heat pumps** with Greenspeed intelligence can run at 40% capacity, 100% capacity, or anywhere in-between to adapt to exactly what the home needs for heat, or in the case of the heat pump, for cooling. The benefit of that range is that the system is smart enough to pick the operating capacity at which it is most efficient. That means you get your precise, desired temperature and you can save money doing it.
