Inverter condenser - Inverter technology changes 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 system - This system is packed with sensors and controls air temperature inside and outside, system performance, duct pressure, refrigerant temperature. The first time you start your system it enters a learning mode keeping air moving across the sensors and storing information so future startups and run cycles will be at max efficiency.

Size for heat - The self-adjusting inverter design allows you to size your system based on heat demand. With standard heat pumps, sizing for heat can mean a muggy house during summer. The ACiQ Next Gen 4-ton heat pump system automatically adjusts to run like a 3-ton, 2-ton or a 1.5-ton to keep you cool and dry

Extreme Heat Technology - Extreme Heat means extended temperature range heating all the way down to -22°F. Traditional heat pumps don't make significant heat below about 30°F outside temperature, below that, they rely on expensive backup electric heat. The ACiQ Next Gen with Extreme Heat 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.


  • Intelligent comfort at an affordable cost
  • 48,000 BTU, 15.6 SEER2 heat pump system for use with ductwork
  • Efficient cooling from 5°F to 122°F outdoor temperatures
  • Efficient heating from -22°F to 75°F outdoor temperatures
  • Durable Gold Fin condenser coil coating
  • Quiet operation at even the highest workloads

48,000 BTU, 15.6 SEER2

    With an efficiency rating of 16 SEER2, the variable output ACiQ-48-HPB will keep you comfortable across a wide range of conditions. Use our handy size calculator Here to determine the demand for your home. For cooling, this system can operate anywhere from 12,000 BTU to 48,000 BTU without short cycling. For heating, this system is capable of 38,400 BTU at -22°F all the way up to 63,744 BTU at 50°F. This increased range means it fits more possible applications.

    Please note that this condenser requires an ACiQ unitary ducted air handler to function, if not already included in the bundle on this page, along with line sets and other installation accessories available at an additional cost in the Accessories section of this page. It is recommended to have a professional install this system because it is not compatible with pre-charged line sets or other DIY equipment.

    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.
