ACiQ 2 Ton (24,000 BTU) 18.1 SEER2 High Efficiency Central Heat Pump | Inverter - R454B & 2 Ton (24,000 BTU) Central Ducted Air Handler - R454B

---

Overview

The ACiQ 2 Ton Heat Pump System combines the advanced ACIQ-24-EHPD inverter condenser and the versatile ACIQ-24-AHD multi-positional air handler for seamless integration with your existing ductwork. This all-electric system continuously adjusts compressor speed to precisely meet heating and cooling demands, eliminating short-cycling and optimizing energy use.

During installation, the “learning condenser” enters a sensor-driven startup mode to gather temperature, duct pressure, and refrigerant data, refining its performance over time for maximum efficiency. Rated to operate from –13 °F in cooling mode and down to 5 °F in heating mode, it delivers consistent comfort in extreme climates.

Backed by a 12-year compressor warranty and 7-year parts coverage (with online registration), this whisper-quiet system (60 dBA outdoor; up to 44 dBA indoor) is an ideal choice for long-term reliability and lower energy bills. Compatible with any 24 V thermostat, it offers flexible installation in upflow, downflow, or horizontal orientations.

How is it different from a traditional heat pump?

• Variable BTU inverter: adjusts output from 12,000 – 24,000 BTU to match demand
• Smart soft-start technology: reduces inrush currents and energy waste
• Heating-sized design: size for heat without short-cycling in cooling mode
• Cold-climate rating: efficient heating performance down to 5 °F outdoor
