ACiQ 1.5 Ton 18.8 SEER2 High Efficiency Central Heat Pump System
The ACiQ 1.5 Ton High-Efficiency Heat Pump System combines the ACIQ-18-EHPD inverter condenser with the ACIQ-18-AHD
variable-speed air handler to deliver intelligent, energy-efficient performance. Designed for compatibility with your
existing ductwork, this system provides superior comfort in a compact, high-performance package.
The ACIQ-18-EHPD features advanced inverter technology that converts AC power to DC, allowing the compressor to
precisely adjust its speed. This ensures the system automatically adapts its BTU output to meet the real-time heating
or cooling demands of your space—enhancing both energy efficiency and performance in all weather conditions.
Built-in sensors continuously track indoor and outdoor temperatures, duct pressure, and refrigerant levels. During its
initial startup, the unit enters a learning mode to collect performance data, allowing it to self-optimize for greater
long-term efficiency and reliability.
Traditional systems sized for heating can lead to overcooling and humidity issues during warmer months. The
ACIQ-18-EHPD solves this with its adaptive inverter design, automatically scaling output to perform like a smaller
system when needed—ensuring year-round comfort without compromise.
The ACIQ-18-AHD air handler is engineered for precise climate control and smooth airflow. It features a variable-speed
DC blower motor and communicating technology that allows real-time interaction between your indoor air handler,
outdoor condenser, and 24V thermostat. This synergy allows the system to automatically adjust BTU output for maximum
efficiency and balanced comfort. Easily installed into your existing ductwork, the ACIQ air handler ensures consistent
air distribution for both heating and cooling, making it a smart and versatile solution for any home.

Installing the ACiQ central ducted air handler is straightforward and similar to replacing a standard air handler. A
licensed technician will complete all necessary electrical, refrigerant, thermostat, and communication line
connections, along with integrating the unit into your existing return and supply ductwork.
Designed for flexibility, this multi-positional air handler supports upflow, downflow, and horizontal installations.
It’s compatible with any 24V thermostat that supports two stages of heating, making it easy to pair with your
preferred control system. For colder climates, optional electric heat kits can be added as a reliable backup heat
source.
An onboard intelligent control board helps simplify diagnostics by displaying fault codes if any issues arise,
streamlining maintenance and service.
Important: This air handler must be installed with a compatible condenser and additional installation components,
which may be sold separately unless included in a bundled system. To enable electric-only heating, an electric heat
kit is required and available at an additional cost.
