59SP5 Performance Boost 90 GAS FURNACE

Brand :

The multi-speed blower motor of this energy-efficient furnace can do more than just add to your comfort. Paired with the right cooling system, it can actually boost SEER levels to help you save on energy costs all year round.

Comfort is enhanced by Ideal Humidity® System technology which improves summer dehumidification from an air conditioner or heat pump. SmartEvap™ technology also aids dehumidification by periodically stopping the multi-speed fan while it's in "Constant ON" mode to give cooling condensation time to drain away deterring re-humidification by up to 10%.
