- The Non-A2L Furnace Integration Kit was created for the HVAC replacement market. It supports systems with either (1) a furnace, indoor coil, and outdoor air conditioner/heat pump, or (2) a modular blower, indoor coil, and outdoor unit. If replacing the indoor coil or outdoor unit, both must be upgraded to R-32 models, but a functioning furnace or modular blower can remain. This kit uses the existing controls of the installed furnace or blower to facilitate the necessary adjustments for R-32 refrigerant systems.
