  • Supports up to 3 attached air handlers
  • Efficient cooling from -22°F to 122°F outdoor temperatures
  • Efficient heating from -22°F to 75°F outdoor temperatures
  • Integrated Extreme Heat technology with base pan heater
  • Gold Fin full-protection coating on condenser coil

ACiQ 9,000 BTU Floor or Ceiling Mount Air Handler Multi-Zone R454B 230V ACIQ-09FM-HH-MD

The ACiQ Floor or Ceiling Mounted Mini Split Air Handler is a flexible indoor unit designed for installations where high-wall placement is not feasible. Delivering 12,000 BTU of powerful heating and cooling, it can be mounted low on the wall or suspended from the ceiling. Its low-profile design and quiet operation make it ideal for sunrooms, attics, and spaces with limited wall space. Adaptive airflow direction optimizes performance in both heating and cooling modes.

Key Features

  • 12,000 BTU floor or ceiling mounted mini split air handler
  • Optimized for heating at floor level and cooling with reversed airflow
  • Energy-efficient with R454B refrigerant and inverter compatibility
  • Ultra-quiet operation as low as 25 dBA
  • Multi-zone compatible design
  • Includes wireless remote controller
  • Ideal for rooms with low walls, sunrooms, or attic remodels

This unit is designed for versatile installations and offers both floor and ceiling mount capability for unique room configurations or limited-space environments.


ACiQ Floor Mounted Air Handler Compact Climate Control for Challenging Spaces ACIQ-12FM-HH-MD

The ACiQ Floor Mounted Air Handler is a space-saving solution ideal for areas where traditional wall-mounted units won't fit, such as sun porches, attic rooms, and remodels with limited vertical wall space. Designed to install low on the wall or even directly on the floor, this console-style HVAC unit provides efficient year-round comfort with powerful heating and cooling capabilities.

Its unique airflow design makes it especially effective in heating applications—warm air is delivered at floor level to reduce heat stratification, ensuring consistent comfort from floor to ceiling. When switched to cooling mode, airflow reverses to improve cold air distribution throughout the room.

Perfect for areas with low ceilings, knee-walls, or windows occupying most wall space, this low-profile mini split air handler offers quiet, reliable operation and flexible placement options.

Key Features:

  • 12,000 BTU of efficient heating and cooling capacity
  • Ideal for small rooms in most climate zones
  • Optimized airflow for superior heating performance
  • Reversible airflow in cooling mode for better air circulation
  • Dry and fan modes for humidity control and air movement
  • Compact, low-profile design fits under windows or on knee-walls
  • Remote control thermostat for convenient temperature adjustments
  • Surface-mount installation on either floor or ceiling
  • Compatible with ACiQ mini split systems
  • Reliable performance for sunrooms, attic remodels, and tight spaces

Note: The 18,000 and 24,000 BTU models differ slightly in appearance from the 12,000 BTU version. Refer to the installation manual for specific mounting instructions.
