Carrier 38mbrcq36aa3 Ductless Heat Pump Condenser 36000 Btu

Product Description

The CARRIER 38mbrcq36aa3 is a single-zone ductless heat pump condensing unit rated at 36,000 BTU/h (3 tons) nominal cooling capacity. It operates on R-410A refrigerant and runs on 208-230 volts, single-phase, 60 Hz power. The unit pairs with a compatible indoor fan coil, connected via refrigerant tubing and low-voltage wiring — no ductwork required. Cooling capacity ranges from 5,900 to 41,000 BTU/h depending on conditions, while heating capacity spans 9,200 to 43,000 BTU/h. An ECM condenser motor and an electronic expansion valve (EEV) handle refrigerant metering and airflow control. Licensed HVAC technicians install and commission this system.

The 38mbrcq36aa3 is designed for residential and light-commercial single-zone applications where ductwork is absent, impractical, or undesirable. Common use cases include room additions, home offices, garage conversions, spaces heated by hydronic or electric systems, and historical renovations where preserving the existing structure is a priority. The outdoor unit connects to one indoor fan coil unit. Maximum piping length is 213 inches and maximum piping height is 98 inches between the indoor and outdoor components. The unit operates at a sound level of 63 dBA.

Compatibility

The 38mbrcq36aa3 is part of the 38MBRC product family and is designed to operate with a matched Carrier, Bryant, or Payne indoor fan coil unit in a single-zone ductless configuration. Connect only one indoor fan coil unit to this outdoor unit.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-410A refrigerant in accordance with EPA Section 608 regulations. Disconnect and lock out all electrical power before servicing or making connections. Maximum overcurrent protection (MOCP) is 50 amps — verify that the branch circuit and disconnect are sized and rated accordingly per NEC requirements. Do not exceed the specified maximum piping length or height between indoor and outdoor units, as this affects system performance and refrigerant charge.
