18,000 BTU, 24 SEER2
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. You will need a professional to add more refrigerant and vacuum the lines as needed. The automated cleaning function will clean your system, but it is recommended to periodically clean the unit's filters manually.
Quality Construction
State-of-the-Art manufacturing is behind every ACiQ product, resulting in quiet, effective operation over a long service life. Most models have low ambient heating and cooling.
Highest Efficiency
ACiQ saves you money up front, but also over time by reducing energy bills. Every ACiQ condenser features a variable inverter twin rotary compressor, lowering wear and increasing performance. Compare specs against other brands in the same price category, and you will agree, ACiQ is the best value.
Longer life, longer warranty
Intelligent design goes into every element of ACiQ’s manufacturing ensuring flawless performance for years. Low friction, variable inverter twin rotary compressors give bulletproof reliability. Register equipment at ACiQ.com to extend warranty protection to 7 years parts, 12 years compressor.
Self Cleaning Condenser
ACiQ condensers stay clean and efficient with self-cleaning technology built right in. At the end of each cycle, the fan reverses direction and blows air out the back of the unit — helping remove leaves, dirt, and debris before buildup can begin.

NEW REFRIGERANT: R454B Model.

- 18,000 BTU wall-mounted air handler with remote
- Intelligent comfort at an affordable cost
Intelligent Heating and Cooling
The ACIQ-18WS-HP230C air handler is designed with a soft LED display on the front of the unit giving you information at a glance. The display shows room temperature by default but can also show temperature setpoint changes and mode changes. To ensure your unit runs properly throughout its lifetime, this display will also show any error codes from its self-diagnosing control board. The display can be switched off if desired, and the included smart remote has a built-in LCD display to show these notifications as well.
WiFi Options
ACIQ is WiFi ready! The wall mounted air handlers come with everything you need to control your home's heating and cooling via smart device (iOS or Android) from anywhere in the world. ACIQ is also compatible with Amazon Alexa and Google Assistant.
Please note that in order to function, this air handler must be installed with a condenser and other installation equipment, available at an additional cost if not already included in this product bundle.
Wall Mounted
Traditional wall-mounted air handlers are the most popular ductless choice due to low cost and ease of installation. Wall mounted units are located high on an outside wall, with refrigerant lines and condensation drain hose exiting the back through a 3" wall penetration. Return air is brought in through vents in the top of the unit, and cooled or heated air exits the lower front through a sweepable louver. Wall mounted air handlers are WiFi compatible and can be controlled by the free NetHome Plus app or by voice assistants such as Alexa or Google Home.
Smartphone App
In addition to the handheld or wired remote that is already included, wall mounted units are WiFi ready, and can be controlled from anywhere with a free app on your tablet or smartphone.
Quiet Comfort
Every ACiQ system is precision engineered to quickly achieve set temperature and hold it there, no matter what the weather is outside. With whisper quiet indoor and outdoor units, ACiQ never intrudes on your peace and quiet.
