At a rated capacity of 18,000 BTU, the output of the ACIQ-18ZS-HP230C when paired with a matching air handler can easily cover a smaller room in ideal climates. Thanks to the unit's high-efficiency rotary compressor and an inverter-integrated motor, the ACIQ-18ZS-HP230C has an efficiency of 24 SEER2. With such a high system SEER2 rating, the system can heat and cool almost any space suitable for its output much more efficiently than most standard central split systems.
Please note that this model of equipment does not have quick connect line set connectors and is not a DIY unit. Installation materials such as line sets, control wire, drain hose, whip and disconnect are not included, but are available at additional cost in the Accessories section on this page.
