ACiQ 2 Ton 17.5 SEER2 Extreme Ceiling Mount Heat Pump Split Inverter R454B

ACiQ Extreme Series 2 Ton 18.3 SEER2 High Efficiency Central Heat Pump Condenser R454B Inverter ACIQ-24-HPD

The ACIQ-24-HPD is a 2-ton heat pump condenser from ACiQ's Extreme Series, engineered specifically for extended cold-weather heating performance. Equipped with true inverter technology, the compressor speeds up and slows down to match real-time heating and cooling demand, delivering an 18.3 SEER2 efficiency rating alongside consistent comfort and reduced energy consumption.

This condenser also functions as a learning system — advanced sensors continuously monitor indoor and outdoor air temperature, duct pressure, refrigerant temperature, and overall performance, using that data to optimize efficiency after an initial startup learning period. Combined with its self-adjusting inverter design, the unit can be sized around heating needs while still maintaining ideal cooling performance without excess humidity.

• "Extreme Heat Technology" delivers 100% heating output at 0°F and 80% output down to -22°F
• Variable BTU output: 12,000-23,000 BTU cooling, 12,000-24,000 BTU heating
• Efficient cooling from -22°F to 122°F and heating from -22°F to 75°F outdoor temperatures
• Durable gold fin condenser coil coating for long-term corrosion resistance
• Pre-charged with R454B refrigerant
• Quiet operation, even under high workloads

Performance Overview

Rated at 2 tons and 18.3 SEER2, the ACIQ-24-HPD is built to provide versatile, reliable comfort across a wide range of climates, with a variable output that eliminates short cycling for lasting efficiency. Because it is designed as part of a matched system, the indoor air handler paired with this condenser should be sized and selected for compatibility to maintain rated performance.

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 equipped with a refrigerant leak detection system. Failure to follow these requirements may result in safety hazards and could void the manufacturer warranty.

ACiQ Extreme Series 2 Ton Ducted Air Handler Ceiling Mounted R454B ACIQ-24W-PB

The ACIQ-24W-PB is a 2-ton ceiling-mounted ducted air handler, commonly referred to as a "pancake" air handler, engineered specifically for use with R454B refrigerant. Its low-profile design is well-suited for installation in drop ceilings and attic spaces, connecting directly to ductwork for whole-space comfort in apartments, condos, and other space-constrained applications.

Designed to pair seamlessly with ACiQ's Extreme Series and other High Efficiency inverter condensers, this air handler is built with durable galvanized-steel construction and offers easy service access for dependable, long-term performance.

Key Features

• 2 ton ceiling-mounted ("pancake") ducted air handler
• Connects directly to ductwork for drop-ceiling and attic installations
• Variable-speed blower motor for efficient, quiet operation
• Galvanized-steel construction for durability
• Easy service access
• Suitable for use with R454B refrigerant
• Supports optional 3 kW, 5 kW, 8 kW, or 10 kW electric heat kits for supplemental or backup heating
• Works with ACiQ's high-efficiency inverter condensers

Performance Overview

Rated at 2 tons, the ACIQ-24W-PB is built to support residential and light commercial heating and cooling applications when paired with a compatible ACiQ condenser. While the air handler requires an outdoor unit to operate as part of a complete system, it can also accommodate optional 3 kW, 5 kW, 8 kW, or 10 kW electric heat kits to provide supplemental electric heating in heat pump configurations.

Installation and Durability

Designed for ceiling mounting in drop-ceiling or attic spaces, this air handler's compact, low-profile cabinet simplifies installation in space-constrained applications while still connecting to standard ductwork. Its reinforced galvanized-steel cabinet is engineered for strength and durability, helping protect internal components and ensure dependable, long-term performance. A 7-year parts warranty is included with online registration.
