Product Details
ACIQ's Central Ducted Heat Pump systems give you the best of both worlds - a self-adjusting, mini-split-style inverter condenser matched to a communicating air handler that attaches seamlessly to your existing ductwork.
How is it different from a traditional heat pump?
- Traditional heat pumps rely on expensive heat strips below 30°F
- ACIQ central ducted heat pumps save up to 75% in temps below 30°F
- Variable BTU inverter ramps up and down to match demand
- Smart system with soft startups to maximize efficiency
- OK to size for heat - will not short cycle during cooling
- Extreme Heat technology keeps you warm to -22°F and beyond
OVERVIEW
Inverter - The ACIQ-42-HPD 3.5 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-42-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-42-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: 12,000-42,000 BTU for cooling, 12,000-50,000 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
3.5 Ton, 16.7 SEER2
Boasting an efficiency rating of 16.7 SEER2, the ACIQ-42-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 the sizing 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.


Quality Construction
State-of-the-Art manufacturing is behind every ACiQ product, resulting in quiet, effective operation over a long service life. Most models have low ambient heating and cooling.
Highest Efficiency
ACiQ saves you money up front, but also over time by reducing energy bills. Every ACiQ condenser features a variable inverter twin rotary compressor, lowering wear and increasing performance. Compare specs against other brands in the same price category, and you will agree, ACiQ is the best value.


Longer life, longer warranty
Intelligent design goes into every element of ACiQ’s manufacturing ensuring flawless performance for years. Low friction, variable inverter twin rotary compressors give bulletproof reliability. Register equipment at ACiQ.com to extend warranty protection to 7 years parts, 12 years compressor.
Enhanced Comfort at Maximum Efficiency
The ACIQ-42-AHD air handler features a variable speed DC blower and communicating technology to maximize comfort and efficiency at the same time. Your thermostat communicates with the inverter condenser outside and the variable speed air handler inside, allowing the system to self-adjust BTU output to maximize efficiency while providing ideal comfort. The air handler efficiently distributes heated and cooled air throughout your home by seamlessly attaching to your existing ductwork.
- 42,000 BTU, 3.5 ton central ducted air handler
- Compatible with any 24v thermostat
- Variable speed DC blower
- Multi-positional - Can be installed in upflow, downflow, or horizontal left/right orientations
- Compatible with R454B refrigerant
Installation and Maintenance
Installation is very similar to installing any replacement air handler. Your technician will make electrical, refrigerant, thermostat, and communication connections. Plus, they will connect the air handler to your return and supply ductwork. The ACIQ central ducted air handler is multi-positional (upflow, downflow or horizontal), making it a very versatile air handler. Any 24v thermostat with 2 stages of heating can control the system. Supplemental electric heat kits are available as a backup heat source for the coldest days of the year. If any maintenance is required, the intelligent control board in the air handler displays fault codes in case any part of the system experiences issues.
Please note - in order to function, this air handler must be installed with a condenser and other installation equipment, available at an additional cost if not already included in this product bundle. To use straight electric heating, an electric heat kit is necessary and is also available at an additional cost.
