Carrier 38mpraq18aa3 Heat Pump Condenser 18000 Btu/h 28.2 Seer

Product Description

The CARRIER 38mpraq18aa3 is an 18,000 BTU/h single-zone ductless heat pump condensing unit rated up to 28.2 SEER, designed for high-efficiency residential and light-commercial cooling and heating applications. It operates on R-410A refrigerant and runs on 208-230 VAC single-phase, 60 Hz power. The unit uses a rotary compressor paired with an ECM condenser fan motor, delivering precise capacity control in both cooling and heating modes. High Heat capability allows the system to maintain 18,000 BTU/h output down to 5 degrees F outdoor ambient, making it suitable for cold-climate installations. ENERGY STAR rated. Licensed HVAC technicians handle installation and commissioning.

This condensing unit is engineered for single-zone ductless mini-split applications in residential and light-commercial settings. It pairs with a compatible indoor air handler as part of the 38MPRA product family. Typical installations include bedroom suites, additions, sunrooms, offices, and other spaces where zoned comfort control is needed. The Electronic Expansion Valve (EEV) metering device enables accurate refrigerant flow management across a wide range of operating conditions. Maximum piping length is 98 feet and maximum piping height is 65 feet, supporting a variety of installation layouts.
