What Is AirFlex™ Technology?


AirFlex technology allows your Lennox Dealer to adjust the SLP98V's gas furnace heating, cooling and fan-on mode blower settings to accommodate your lifestyle, home design and geographic location. For example, your dealer can choose a setting that increases airflow during fan-on operation to compensate for cathedral ceilings or long duct runs. If you live in a humid climate, your dealer may choose a slower fan-on setting that helps minimize off-cycle re-humidification.
