ACiQ 4 Ton 16 SEER2 Central Heat Pump System Inverter High Efficiency R454B


ACiQ 4 Ton 16 SEER2 Central Heat Pump Inverter Condenser Two-Stage R454B ACIQ-48-EHPD

ACiQ 4 Ton Inverter Heat Pump – Model ACiQ-48-EHPD Built for large-scale comfort and high efficiency, this 4-ton inverter heat pump delivers 12,000–48,000 BTUs of variable heating and cooling power. With advanced inverter technology, a self-learning condenser, and adaptive sizing, it ensures consistent performance in any climate—from -13°F to 122°F. The two-stage design, R454B refrigerant and durable gold fin coil make it a powerful, quiet, and eco-friendly solution for ducted systems.

Key Features

  • Powerful Inverter Heat Pump Technology: Converts AC power to DC, allowing the variable-speed compressor to adjust output between 12,000 and 48,000 BTU for both heating and cooling—delivering flexible, energy-saving performance all year long.

  • Smart Learning Condenser: Built-in sensors track duct pressure, indoor/outdoor temperatures, and refrigerant levels. The unit enters a learning mode during initial startup, optimizing future performance for enhanced efficiency.

  • Adaptive Sizing Performance: Automatically adjusts capacity based on your home's heating or cooling demands. Functions like a smaller system during milder conditions to reduce overcooling and maintain consistent humidity control.

  • High-Capacity, Energy-Efficient HVAC Solution: Designed for ducted installations, this 4 ton inverter heat pump delivers reliable comfort with significantly reduced energy consumption—ideal for larger homes or light commercial spaces.

  • Reliable in Extreme Climates: Operates efficiently in harsh conditions, with cooling performance from -13°F to 122°F and heating functionality from -13°F to 75°F.

  • Eco-Friendly R454B Refrigerant: Utilizes R454B refrigerant with a lower global warming potential (GWP), making it a future-proof, environmentally responsible HVAC choice.

  • Gold Fin Condenser Coil for Durability: Features corrosion-resistant gold fin coil coating to extend unit lifespan and maintain performance, even in coastal or high-humidity environments.

  • Quiet Operation: Engineered for silent running—even during full load—perfect for residential applications where noise matters.

  • Ducted HVAC Compatibility: Seamlessly integrates with existing duct systems, providing a centralized, high-capacity solution for modern comfort control.

Installation and Maintenance

Installing the ACIQ central ducted air handler is straightforward and similar to replacing a standard air handler. Your HVAC technician will handle all necessary connections, including electrical, refrigerant lines, thermostat wiring, and system communication links. The unit also connects directly to your existing return and supply ductwork.

Thanks to its multi-positional design—compatible with upflow, downflow, or horizontal configurations—this air handler offers flexible installation options to suit a variety of spaces. It can be controlled by any 24V thermostat that supports two stages of heating.

For added comfort during colder weather, optional supplemental electric heat kits are available as a backup heat source. If maintenance is ever required, the built-in intelligent control board displays diagnostic fault codes to help quickly identify and resolve issues.

Please note: This air handler must be paired with a compatible condenser and other required installation components, which may be sold separately if not included in your product bundle. To enable electric-only heating, an electric heat kit (sold separately) is required.
