Product overview

OVERVIEW

Inverter - The ACiQ-18-HPD 1.5 ton Extreme series central inverter heat pump utilizes inverter technology to convert AC power to DC, allowing the compressor inside your condenser to speed up and slow down. This allows the system to self-adjust BTU output based on demand. As the weather changes, so will your system output.

Learning Condenser - Equipped with advanced sensors, this condenser monitors indoor and outdoor air temperature, duct pressure, refrigerant temperature, and overall performance. During the initial startup, it enters a learning mode that optimizes future operations for maximum efficiency by collecting and storing data.

Adaptive Sizing - With its self-adjusting inverter design, the ACiQ-18-HPD can be sized based on your heating needs. Standard heat pumps may cause discomfort during summer when sized for heat, but this unit automatically adjusts to function like a smaller unit, ensuring ideal cooling performance without excess humidity.

Extreme Heat Technology - "Extreme Heat" means extended temperature range heating all the way down to -22°F. Traditional heat pumps cannot produce significant heat below about 30°F outside temperature. Below that threshold, they rely on expensive backup electric heat. The ACiQ-18-HPD uses the inverter to vary the refrigerant flow, allowing for maximum heat extraction during extreme cold temperatures. The backup electric heat supplements the heat pump, and only takes over below -22°F. The heat pump gives 100% at 0°F, and still gives 80% at -22°F, saving you up to 75% on cold weather heating bills.

QUICK FACTS

  • Variable BTU output based on demand: 12,000-18,000 BTU for cooling, 12,000-19,000 for heating
  • R454B refrigerant
  • Inverter heat pump system for ducted applications
  • Efficient cooling from -22°F to 122°F outdoor temperatures
  • Efficient heating from -22°F to 75°F outdoor temperatures
  • Durable gold fin condenser coil coating for longevity
  • Quiet operation, even under high workloads

1.5 Ton, 19 SEER2

Boasting an efficiency rating of 19 SEER2, the ACiQ-18-HPD provides versatile comfort across a range of climates by providing reliable comfort with a variable output that eliminates short cycling for lasting efficiency. Use our sizing calculator (found BTU Calculator) to determine the demand for your home.


Extreme Heat Base Pan Heater Technology

Each ACiQ condenser has integrated Extreme Heat technology to maximize heat performance in extreme cold weather. Extended heat pump performance (HyperHeat) harnesses the power of inverter condenser with outdoor temp sensing, variable refrigerant flow and variable condenser fan speed to maximize heat extraction all the way down to -22°F. Plus, every Extreme Heat ACiQ condenser includes a base pan heater to keep ice from collecting on the condenser coil during heat pump operation.
