Outdoor Unit Single-Zone Ductless Heat Pump QuietComfort Series Compact High-Heat Inverter R-454B 36,000 BTU 208/230 V 1-Phase 60 Hz

The Outdoor Unit Single-Zone Ductless Heat Pump QuietComfort Series Compact High-Heat Inverter R-454B 36,000 BTU 208/230 V 1-Phase 60 Hz (D5CUHAH36AAK) is a compact, cold-climate outdoor condenser engineered to maintain heating performance at lower outdoor temperatures. Rated at 36,000 BTU (3 ton), this high-heat configuration sustains output deeper into winter conditions while inverter modulation delivers stable comfort, improved part-load efficiency, and controlled sound levels using R-454B refrigerant. It operates on 208/230 V single-phase, 60 Hz power. For proper job fit, technicians must verify the indoor unit is approved for high-heat pairing at 36K, confirm refrigerant line sizing and allowable piping lengths, and ensure the electrical service meets published MCA and MOCP requirements. Selecting a compact high-heat model improves winter reliability where space or climate demands require it.
