ACiQ Extreme Series 1.5 Ton 19 SEER2 High Efficiency Heat Pump Condenser R454B Inverter ACIQ-18-HPD
The ACIQ-18-HPD is a high-efficiency 1.5-ton Extreme Series heat pump condenser engineered to deliver reliable, year-round comfort even in the coldest climates. Built with advanced inverter technology and a 19 SEER2 efficiency rating, this condenser automatically adjusts output based on real-time heating and cooling demand.
Equipped with advanced sensors, the condenser continuously monitors indoor and outdoor air temperature, duct pressure, and refrigerant temperature, entering a learning mode during initial startup to optimize future performance. Its self-adjusting inverter design allows the system to be sized for heating needs while still delivering ideal cooling performance without excess humidity. Extreme Heat Technology extends efficient heating all the way down to -22°F outdoor temperatures, with the heat pump delivering 100% capacity at 0°F and still 80% at -22°F, reducing reliance on backup electric heat and cutting cold-weather heating bills by up to 75%.
Key Features
- Variable BTU output based on demand: 12,000-18,000 BTU for cooling, 12,000-19,000 BTU 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
Performance Overview
Boasting an efficiency rating of 19 SEER2, the ACIQ-18-HPD provides versatile comfort across a range of climates with a variable output that eliminates short cycling for lasting efficiency. At 0°F, this heat pump operates at 94% efficiency, making it a strong fit for maximizing performance in the coldest climates.
Please note that this condenser cannot operate independently and must be installed with a compatible indoor air handler.
Important Refrigerant Safety Notice
This condenser uses R454B refrigerant, classified as an A2L refrigerant. To comply with safety standards and maintain warranty coverage, the unit must be paired with an R454B-compatible air handler or evaporator coil equipped with a refrigerant leak detection system. Failure to follow these requirements may result in safety hazards and could void the manufacturer warranty. For compatibility questions, please call 1-888-557-9206.
