Product Details

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. Designed for large homes and high-demand environments, this 4-ton inverter heat pump delivers 12,000–48,000 BTUs of variable heating and cooling. With inverter technology, a self-learning condenser, and adaptive sizing, it provides consistent comfort from -13°F to 122°F. The system uses R454B refrigerant, includes a corrosion-resistant gold fin coil, and operates quietly—making it a powerful, efficient, and eco-friendly solution for ducted HVAC setups.

ACiQ-48-EHPD 4 Ton Central Inverter Heat Pump – Key Features

  • Powerful Inverter Technology: Variable-speed compressor adjusts output between 12,000 and 48,000 BTU for efficient, flexible heating and cooling year-round.
  • Smart Learning Condenser: Sensors monitor duct pressure, temperature, and refrigerant levels. The system enters a “learning mode” during startup to optimize long-term performance.
  • Adaptive Sizing Performance: Automatically adjusts capacity based on conditions, reducing overcooling and improving humidity control during mild weather.
  • High-Capacity, Energy-Efficient Solution: Ideal for ducted installations in large homes or light commercial environments, providing strong performance with reduced energy consumption.
  • Reliable in Extreme Climates: Efficient operation from -13°F to 122°F in cooling mode and -13°F to 75°F in heating mode.
  • Eco-Friendly R454B Refrigerant: Uses low-GWP R454B refrigerant for a more sustainable, future-ready HVAC system.
  • Gold Fin Condenser Coil: Corrosion-resistant coating improves durability and maintains performance in coastal or humid environments.
  • Quiet Operation: Designed for low-noise performance, even during high-demand operation—ideal for residential spaces.
  • Ducted HVAC Compatibility: Seamlessly integrates with existing duct systems for modern, centralized comfort control.
