Carrier 40mhhc24---3 Ductless High Wall Fan Coil 24000 Btu

Product Description

The CARRIER 40mhhc24---3 is a ductless high-wall indoor fan coil unit rated at 24,000 BTU/h (2 tons) for cooling-only applications using R-410A refrigerant. It operates on 208-230 volts, single phase, 60 Hz and is driven by an ECM (Electronically Commutated Motor) blower running at 1,150 RPM across four speed settings. The unit delivers 420 to 640 CFM and achieves an EER of 10.9 and a SEER of 17.5. Wall-mounted near the ceiling, it pairs with a compatible outdoor condensing unit connected via refrigerant tubing and low-voltage wiring. Installation is performed by licensed HVAC technicians.

This fan coil is designed for residential and light-commercial ductless split applications where traditional ducted systems are impractical or unavailable. Typical use cases include room additions, offices, family rooms, spaces heated by hydronic or electric systems with no existing ductwork, and historical renovation projects where preserving original building aesthetics is essential. The unit is well-suited for any single-zone cooling application requiring a clean, wall-mounted indoor solution without ductwork.

Compatibility

Part of the Carrier 40MHH product family. Designed to operate as the indoor fan coil component of a matched ductless split system paired with a compatible Carrier outdoor condensing unit connected via R-410A refrigerant lines and low-voltage wiring.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-410A refrigerant in accordance with EPA Section 608 requirements. Power must be disconnected at the circuit breaker before any electrical connections are made. The suction line requires a sweat or braze connection; the liquid line uses a flare fitting. Verify that the outdoor condensing unit is a factory-matched companion unit before commissioning the system.
