ACiQ 1.5 Ton 18.8 SEER2 High Efficiency Central Heat Pump | Inverter - R454B & ACiQ 1.5 Ton Central Ducted Air Handler - R454B
Overview
The ACiQ 1.5 Ton Heat Pump System combines cutting-edge inverter technology with robust build quality to deliver year-round comfort and exceptional energy savings. At its heart is the ACIQ-18-EHPD inverter condenser, which continuously adjusts compressor speed to precisely match heating or cooling demand, eliminating short-cycling and minimizing energy waste. Paired with the ACIQ-18-AHD multi-positional air handler—capable of upflow, downflow, or horizontal installation—this system seamlessly integrates into your existing ductwork for uniform temperature control throughout your home.
Unlike traditional fixed-speed heat pumps, this system’s “learning condenser” feature gathers ambient and duct conditions during initial startups and refines its operating curves over time. The result is a self-optimizing unit that delivers reliable performance even in extreme climates, operating efficiently down to –13°F in cooling mode and as low as 5°F in heating mode. With a robust gold-fin coil coating, enhanced sensors, and soft-start circuitry, the ACiQ system not only maximizes comfort but also extends component life and reduces maintenance needs.
Backed by a 12-year compressor warranty and 7-year parts coverage (with online registration), the ACiQ 1.5 Ton system represents a smart investment in long-term reliability and lower utility bills. Whether you’re retrofitting an older home or equipping a new construction, this high-efficiency heat pump delivers whisper-quiet operation (34–55 dBA), flexible installation options, and compatibility with any standard 24 V thermostat—making it an ideal choice for homeowners seeking both performance and peace of mind.
How is it different from a traditional heat pump?
- Variable BTU Inverter: Automatically adjusts output to match demand.
- Smart system with soft startups: Maximizes efficiency and reduces energy waste.
- Sized for heating: Allows you to size for heat without worrying about short cycling in cooling mode.
- Rated for efficient heating: Operates down to 5°F outdoor temperatures.
