Goodman fdma18avju9 Concealed Ducted Indoor Unit 18000 Btu/h

Product Description

The GOODMAN fdma18avju9 is a concealed horizontal ducted indoor unit designed for ductless split and multi-split HVAC systems using R32 refrigerant. Rated at 18,000 BTU/h nominal capacity, it delivers 17,600 BTU/h in cooling mode and 21,600 BTU/h in heating mode. The unit operates with inverter-driven technology, allowing variable-speed compressor control that adjusts output to match load conditions rather than cycling on and off at fixed capacity. Designed for above-ceiling or concealed horizontal installation, it connects to existing ductwork for discreet airflow distribution. Installation is typically performed by a licensed HVAC technician certified to handle R32 refrigerant systems.

The fdma18avju9 is suited for residential and light commercial applications where a visible wall-mounted or ceiling cassette unit is not acceptable. Common install scenarios include hotel rooms, medical offices, conference rooms, and residential spaces where the air handler must be hidden above a dropped ceiling with short duct runs. The unit pairs with a compatible outdoor inverter condensing unit in a dedicated or multi-zone split configuration. Built-in filtration supports improved indoor air quality in occupied spaces that require continuous operation.

Key Features

• 18,000 BTU/h nominal capacity with 17,600 BTU/h cooling and 21,600 BTU/h heating output
• Inverter-driven variable-speed operation for load-matched performance and reduced energy consumption
• Concealed horizontal ducted design for above-ceiling installation with duct distribution
• R32 refrigerant system with lower global warming potential compared to R410A
• Integrated filtration for improved indoor air quality in continuously occupied spaces

Compatibility

Designed as an OEM-style concealed horizontal ducted indoor unit for use in R32 inverter split and multi-split HVAC system configurations.

Installation Notes

Installation must be performed by a licensed HVAC technician holding applicable refrigerant handling certification for R32 systems, as R32 is classified as a mildly flammable refrigerant (A2L) under ASHRAE 34. Disconnect and lock out all electrical power to the system before servicing or making refrigerant connections. Follow local mechanical and electrical codes, including applicable sections of the IMC and NEC, for equipment mounting, drain line routing, and low-voltage control wiring. Do not substitute refrigerant types or mix refrigerants in the system circuit.
