  • Integrated Extreme Heat technology and base pan heater for cold climates
  • Gold Fin condenser coil coating for corrosion resistance
  • Twin rotary inverter compressor for quieter and more durable operation
  • Pre-charged with R410A refrigerant for 25’ per line set connection
  • Self-diagnostic control board with alerts for easy troubleshooting

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.


ACiQ 18,000 BTU Extreme Series Floor/Ceiling Mounted Air Handler R454B 230V ACIQ-18FM-HH-MD x2

The ACiQ 18,000 BTU Floor or Ceiling Mounted Air Handler offers flexible installation in challenging spaces where high-wall mounting isn't possible. Its compact form and powerful airflow design make it ideal for sunrooms, attic remodels, or rooms with knee walls or below-window space. This unit can be wall-mounted close to the floor or suspended from the ceiling using an adjustable rod system, and it includes a wireless remote for intuitive control. Its whisper-quiet performance and low-profile design deliver both functionality and comfort for any interior space.

Key Features

  • 18,000 BTU (cooling: 17,000 / heating: 19,000 BTU)
  • Versatile installation – floor- or ceiling-mounted configuration
  • Ideal for sunrooms, attics, or rooms with angled ceilings
  • Maximum CFM: 576.8 with quiet operation as low as 29 dBA
  • Pre-wired for condensate pump with overflow shutoff
  • Wireless remote included
  • R454B refrigerant – eco-friendly and efficient
  • Energy Star certified

This unit is designed for creative installation solutions where traditional wall-mounted systems won’t work. Whether elevated above a windowsill or suspended from a ceiling, it provides quiet, efficient comfort.
