Description
Overview
The Starling Series 18,000 BTU heat pump system is a bundled product that includes 1 indoor unit (TACCI7H4R18) and 1 outdoor unit (TACEM7H4R18). It is rated for 18,000 BTU/h cooling and 19,100 BTU/h heating with 20 SEER2 and 8.5 HSPF2 performance. Electrical requirements are 208/230V, 60 Hz, single phase. The system uses R32 refrigerant with a factory charge of 32.5 oz (0.92 kg). Indoor and outdoor heat transfer surfaces use aluminum fin-copper tube coil construction.
Performance
Cooling output modulates from 3,753 to 20,300 BTU/h with rated cooling power input of 1,500 W. Heating output modulates from 2,730 to 22,500 BTU/h with rated heating power input of 1,435 W. Efficiency metrics include 12.35 EER2 and 13.31 COP, supporting seasonal operation planning. The outdoor unit uses a Rotary compressor and an Axial-flow fan with 1,483 CFM airflow for heat rejection. Line set design supports 24.6 ft standard connection pipe length and up to 131.2 ft total length with 82 ft maximum height difference.
Smart Features
Temperature control is supported across a 61ā86 Ā°F setpoint range. The indoor unit is specified with controller model YBE1FB1F, enabling system configuration and operation. Outdoor defrosting method is Automatic Defrosting, supporting heating performance in low ambient operation. The throttling method is Capillary, which regulates refrigerant flow through the refrigeration cycle. Moisture protection rating is IPX4 for outdoor environmental exposure.
Comfort & Noise
Indoor airflow is available up to 618 CFM with multiple fan settings including Super Low and SS (Max). Indoor sound pressure level in cooling ranges from 34 to 53 dB(A) across listed fan settings. Indoor sound pressure level in heating ranges from 30 to 49 dB(A) across listed fan settings. The outdoor unit sound pressure level is 57 dB(A) at the listed operating condition. Rated dehumidification capacity is 1.8 L/h (3.8 pint/h), helping manage indoor moisture during cooling operation.
Use Case Fit
Application area guidance is 23-34 mĀ², supporting room-by-room sizing decisions. Cooling ambient temperature range is 0~118 Ā°F and heating ambient temperature range is -13~75 Ā°F, aligning with seasonal operating envelopes. Liquid line size is 1/4 in and gas line size is 1/2 in for refrigerant piping selection. Minimum circuit ampacity is 13 A and maximum overcurrent protection is 15 A for electrical planning. This bundled configuration supports a single indoor zone served by one matched outdoor unit.
Value & Reliability
The indoor unit uses a cross-flow fan design and aluminum fin-copper tube evaporator coil construction. The outdoor unit uses aluminum fin-copper tube condenser construction and permissible excessive operating pressure ratings up to 624 PSI (discharge) and 363 PSI (suction). Built-in automatic defrosting supports cold-weather heating operation without manual intervention. Outdoor moisture protection rating IPX4 supports placement in exposed outdoor locations. Service planning is supported by listed compressor manufacturer ZHUHAI LANDA COMPRESSOR CO., LTD. (GREE) and compressor model QXF-A120zF170.
Summary Wrap-Up
This Starling Series bundle pairs matched TACCI indoor and TACEM outdoor units for 18,000 BTU/h cooling and 19,100 BTU/h heating. It combines R32 refrigerant, 20 SEER2 performance, and a Rotary compressor to support year-round operation. Air delivery up to 618 CFM and dehumidification capacity 3.8 pint/h help manage comfort in occupied spaces. Long line capability up to 131.2 ft and 82 ft elevation change supports flexible indoor-outdoor placement. Use this system when you need a matched split heat pump package with defined electrical, sound, and piping specifications for direct-to-consumer or wholesale purchasing.
