55,000 BTU, 22.2 SEER2
The 55,000 BTU, ACIQ-55z-HH-M6C is designed to easily support up to 4 air handlers at up to 1.25 times the condenser BTU rating, or 60,000 BTU across all air handlers. This adaptive, inverter condenser is constantly self-adjusting to provide the precise amount of heating or cooling needed to maintain your desired temperature in each room or zone. You can set different temperatures room by room, even turn off heating and cooling in unused areas. This, combined with a high efficiency rating of 22.2 SEER2, means you are buying a system designed to intelligently save you money both up front and over the lifetime of the unit.
Although the condenser is pre-charged, please note that this model of equipment 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 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.
Extreme Heat Base Pan Heater Technology
Each ACiQ condenser has integrated Extreme Heat technology to maximize heat performance in extreme cold weather. Extended heat pump performance (HyperHeat) harnesses the power of inverter condenser with outdoor temp sensing, variable refrigerant flow and variable condenser fan speed to maximize heat extraction all the way down to -22°F. Plus, every Extreme Heat ACiQ condenser includes a base pan heater to keep ice from collecting on the condenser coil during heat pump operation.


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.
Installation and Maintenance
ACiQ multi zone condensers are pre-charged with R410-A refrigerant for 25' per air handler connection. In many cases, no additional refrigerant is needed. All units are run-tested at the factory for years of trouble-free performance. Troubleshooting is easy thanks to unit's self diagnosing control board with alerts that are sent to each connected air handler.
