Product Summary
The Daikin SkyAir RZA24AAVJU-FBA24AAVJU is a matched 24,000 BTU (2 ton) single-zone heat pump system. It pairs the RZA24AAVJU inverter outdoor unit with the FBA24AAVJU high static concealed ducted indoor unit, runs on 208/230V 1-Phase power and uses R-32 refrigerant.
As a matched set it carries AHRI Reference No. 217175220 and is rated at 16.2 SEER2 and 11.7 EER2, with 9.3 HSPF2 in heating. It keeps heating down to -4°F outdoors.
The concealed ducted indoor unit hides above a ceiling or in a closet and feeds one or more rooms through short duct runs, so only the grilles show.
