IMPORTANT: This is only one part of the system. To complete your setup, you must also purchase a compatible indoor or outdoor unit that uses the same refrigerant type (R454B, R32 or R410A). Additionally do not mix and match brands (Ex Cooper&Hunter, Bravo, or OLMO).

⚠️ Do not mix R454B, R32 and R410A units—they are not compatible with each other.

ACiQ 18,000 BTU 1.5 Ton 25.1 SEER2 High Efficiency Multi-Zone Condenser | Inverter - R454B

Model: ES-18Z-M3C

Summary

The ACiQ ES-18Z-M3C is a high-efficiency, multi-zone heat pump condenser designed to support up to 3 indoor air handlers. With an impressive 25.1 SEER2 rating and inverter technology, this 18,000 BTU unit automatically adjusts performance to maintain precise temperatures while maximizing energy efficiency.

This all-season solution provides efficient cooling in outdoor temperatures from -13°F to 122°F and heating from -13°F to 75°F. The Gold Fin full-protection coating on the condenser coil enhances durability, while quiet operation (59.5 dB) makes it suitable for residential applications.

Ideal for creating customized comfort zones, this system allows different temperature settings in each room and can be paired with various ACiQ indoor unit types. The advanced inverter technology and high SEER2 rating deliver significant energy savings over conventional systems.

Important

Professional installation required - this is not a DIY unit. Registration is required within 60 days of installation for full warranty coverage. A minimum of two air handlers must be connected for the system to function properly.
