Product Overview
ACIQ 1.5 Ton 19 SEER2 High Efficiency Central Heat Pump | Inverter | Extreme Series - R454B
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.

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 ) 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.
Heats down to −22°F and cools up to 115°F
Enjoy your ACiQ heat pump system year round with unprecidented heating and cooling performance. Not only that, it is extremely efficient saving you money year round!
Self Cleaning Condenser
ACiQ condensers stay clean and efficient with self-cleaning technology built right in. At the end of each cycle, the fan reverses direction and blows air out the back of the unit — helping remove leaves, dirt, and debris before buildup can begin.
1.5 Ton Ceiling-Mount ACIQ Air Handler-R454B
The ACIQ Ceiling Mounted Ducted Air Handler, commonly known as the "pancake" air handler, is specifically engineered for use with R454B refrigerant. It is well-suited for installation in drop ceilings and attic spaces and connects directly to ductwork. Designed to pair seamlessly with ACIQ High Efficiency inverter systems, this unit delivers optimal efficiency and quiet operation. Durably built with galvanized-steel construction and offering easy service access, it provides dependable performance. A 7-year parts warranty is included with online registration, ensuring lasting peace of mind.
