Product Details

ACIQ Standard Series 1.5 Ton 18.8 SEER2 High Efficiency Heat Pump Condenser - R454B Inverter - ACIQ-18-EHPD

Inverter - The ACIQ-18-EHPD 1.5 ton central inverter heat pump utilizes inverter technology to convert AC power to DC, allowing the compressor to adjust its speed. This enables the condenser to modify its BTU output based on the current demand, providing efficient and adaptable performance throughout varying weather conditions.

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, optimizing future operations for maximum efficiency by collecting and storing data.

Adaptive Sizing - With its self-adjusting inverter design, the ACIQ-18-EHPD 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.

Key Features

  • Variable output based on demand: 12,000-18,000 BTU for cooling, 12,000-18,000 BTU for heating
  • R454B refrigerant
  • Inverter heat pump system for ducted applications
  • Efficient cooling from -13°F to 122°F outdoor temperatures
  • Reliable heating from -13°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 18.8 SEER2, the ACIQ-18-EHPD provides versatile comfort across a range of climates, delivering reliable performance with a variable output that eliminates short cycling for lasting efficiency.

Not all heat pumps are built the same — depending on the climate where you live, the right fit can depend dramatically on the heat pump's efficiency at lower temperatures. At 0°F, this heat pump operates at 58% efficiency, making it a great fit for moderate climates that have some chilly days.

Please note that this condenser cannot operate independently and must be installed with a compatible indoor air handler or evaporator coil.

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.
