Better : Performance Series (80% AFUE)

Performance™ 80 Gas Furnace

If you want performance without all the bells and whistles of a communicating system, consider this Performance series model.

As an 80% furnace it is most suitable for areas with milder winters. You can pair it with a high–efficiency heat pump or air conditioner and gain a cooling efficiency boost from its variable speed blower.

Because it’s variable speed, you gain greater comfort through more consistent temperatures with the added benefit of smarter energy use.

It also features SmartEvapTM technology which periodically stops the fan in "Constant ON" mode to give cooling condensation time to drain away. 

And ComfortFanTM technology allows you to choose fan speeds in "Constant ON" mode from a compatible thermostat.
