Carrier 40mbabq24xb3 Ductless Fan Coil Unit 24000 Btu/h

Product Description

The CARRIER 40mbabq24xb3 is a 2-ton ductless fan coil unit designed for multi-position ducted installation in split heat pump systems. Rated at 24,000 BTU/h for both cooling and heating, it operates on R-410A refrigerant and runs on 208-230 VAC single-phase, 60 Hz power. The unit uses an ECM blower motor rated at 1/3 HP and 550 RPM, delivering airflow between 629 and 824 CFM across four speeds. With a SEER rating of 18-20 and a sound level range of 32.2-42.5 dBA, this coil is built for efficient, quiet performance in residential and light commercial ductless installations. A licensed HVAC technician handles the refrigerant connections and electrical hookup.

This fan coil unit is suited for ducted multi-position ductless heat pump applications where a compact air handler is needed in place of a traditional air handler. It supports multi-zone configurations and is compatible with sweat or braze refrigerant line connections using a 3/8-inch liquid line and a 5/8-inch suction line. Typical installations include new construction and retrofit projects in residential settings where quiet, efficient zone heating and cooling are priorities. The unit ships in gray and includes a remote control.

Compatibility

Part of the Carrier 40MBAB product family, also marketed under the Bryant and Payne brands. Designed for use in ducted ductless split heat pump systems requiring a 2-ton multi-position fan coil unit with R-410A refrigerant and 208-230 VAC single-phase power.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-410A refrigerant under EPA Section 608 requirements. Disconnect and lock out all electrical power before beginning any wiring or refrigerant line work. Refrigerant line connections are sweat or braze type; follow standard brazing procedures and pressure-test the system before charging. Verify drain line pitch and connection integrity at the 3/4-inch drain port before startup.
