48,000 BTU ACiQ Multi Zone Condenser

Introducing ACiQ's ES-48Z-M5B Multi-Zone Heat Pump Condenser

ACiQ offers a smart solution to adaptive heating and cooling for almost any space and climate, all at an affordable cost. The ES-48Z-M5B is a multi-zone heat pump condenser that can run up to 5 air handlers off a single condenser, saving space outside while keeping your home perfectly comfortable. Here are some quick facts about this impressive unit:

Quick Facts:

  • 48,000 BTU, 23.4 SEER2 multi-zone heat pump condenser
  • Designed to function with up to 5 attached air handlers
  • Efficient cooling from 5°F to 122°F outdoor temperatures
  • Efficient heating from -13°F to 75°F outdoor temperatures
  • Integrated Max Heat technology with base pan heater
  • Gold Fin full-protection coating on condenser coil
  • Quiet operation at even the highest workloads

48,000 BTU, 23.4 SEER2

The ES-48Z-M5B is a versatile unit that can easily support up to 5 air handlers with up to 1.25 times the condenser BTU rating, or 60,000 BTU across all air handlers. This adaptive, inverter condenser constantly self-adjusts to provide the precise amount of heating or cooling needed to maintain your desired temperature in each room or zone. With the ability to set different temperatures in each room, you can even turn off heating and cooling in unused areas. The high efficiency rating of 23.4 SEER2 means you are buying a system designed to intelligently save you money both upfront and over the lifetime of the unit.

Please note that although the condenser is pre-charged, this unit does not have quick-connect line set connectors and is not a self-install unit. You will need a professional to add more refrigerant and vacuum the lines as needed. Installation materials such as line sets, control wire, drain hose, whip, and disconnect are not included but are available at an additional cost in the Accessories section to the right of this text. For all multi-zone ACiQ condensers, a minimum of two air handlers is needed for the unit to function.

12,000/18,000 BTU Slim Ceiling Cassette ACiQ Mini Split Air Handler

Slim Ceiling Cassettes give you the advantages of a traditional cassette, but in a slimmer profile designed to fit between 16”-on-center joists. This means an easier installation in many cases.

Slim Ceiling Cassettes have a one-way air delivery, taking in return air along one edge and delivering conditioned air out the other. Traditional ceiling cassettes send conditioned air out in 4 directions and take return air in at the center.

Slim Ceiling Cassette air handlers provide the same high-efficiency heating and cooling of a regular wall-mounted unit and come with a hand-held remote control. Once mounted in the ceiling, only the grille is visible for the most understated appearance.

Switchable Sizing

  • ACiQ-SCC1218 – 18,000 BTU default, switchable to 12,000 BTU by changing the dip switch

Installation Considerations

Slim Ceiling Cassettes are flush-mounted, which requires removal of enough ceiling material to create a cavity for the unit. The Slim Ceiling cassette is designed to fit between 16” on center joists, and the narrow profile means no changes to your framing will be required in most cases. Additionally, Ceiling Cassettes have factory-installed, onboard condensate pumps to lift the condensation up to 14 inches. From there, it will be necessary to construct a PVC drain system to route the condensation to a safe wastewater location. Refrigerant and wiring connections are the same as the wall mounted units.


  • Narrow profile fits between 16 inch-on-center joists
  • Switchable size – select between 12,000 BTU and 18,000 BTU
  • No-ladder filter cleaning – grille lowers on cables for easy access to filter
  • Handheld remote included
  • Decorative Grille included
