At its heart is the ACIQ-18-EHPD inverter condenser, which continuously adjusts compressor speed to precisely match heating or cooling demand, eliminating short-cycling and minimizing energy waste. Paired with the ACIQ-18-AHD multi-positional air handler—capable of upflow, downflow, or horizontal installation—this system seamlessly integrates into your existing ductwork for uniform temperature control throughout your home.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional fixed-speed heat pumps, this system’s “learning condenser” feature gathers ambient and duct conditions during initial startups and refines its operating curves over time. The result is a self-optimizing unit that delivers reliable performance even in extreme climates, operating efficiently down to –13°F in cooling mode and as low as 5°F in heating mode. With a robust gold-fin coil coating, enhanced sensors, and soft-start circuitry, the ACiQ system not only maximizes comfort but also extends component life and reduces maintenance needs.\u003c\/p\u003e\n\u003cp\u003eBacked by a 12-year compressor warranty and 7-year parts coverage (with online registration), the ACiQ 1.5 Ton system represents a smart investment in long-term reliability and lower utility bills. Whether you’re retrofitting an older home or equipping a new construction, this high-efficiency heat pump delivers whisper-quiet operation (34–55 dBA), flexible installation options, and compatibility with any standard 24 V thermostat—making it an ideal choice for homeowners seeking both performance and peace of mind.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eHow is it different from a traditional heat pump?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVariable BTU Inverter: Automatically adjusts output to match demand.\u003c\/li\u003e\n\u003cli\u003eSmart system with soft startups: Maximizes efficiency and reduces energy waste.\u003c\/li\u003e\n\u003cli\u003eSized for heating: Allows you to size for heat without worrying about short cycling in cooling mode.\u003c\/li\u003e\n\u003cli\u003eRated for efficient heating: Operates down to 5°F outdoor temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eQuick Facts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVariable output based on demand: 12,000–18,000 BTU for cooling and heating\u003c\/li\u003e\n\u003cli\u003eRefrigerant: R454B\u003c\/li\u003e\n\u003cli\u003eInverter heat pump system for ducted applications\u003c\/li\u003e\n\u003cli\u003eEfficient cooling from –13°F to 122°F outdoor temperatures\u003c\/li\u003e\n\u003cli\u003eReliable heating from –13°F to 75°F outdoor temperatures\u003c\/li\u003e\n\u003cli\u003eDurable gold-fin condenser coil coating for longevity\u003c\/li\u003e\n\u003cli\u003eQuiet operation, even under high workloads (34–55 dBA)\u003c\/li\u003e\n\u003cli\u003e1.5 Ton, 18.8 SEER2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse our sizing calculator (\u003ca href=\"https:\/\/southminisplits.com\/pages\/sizing-calculator\" target=\"_blank\"\u003eHERE\u003c\/a\u003e) to determine the demand for your home.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eIncluded in Your Order:\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eACiQ 1.5 Ton Inverter Condenser\u003c\/strong\u003e – Model: \u003cstrong\u003eACIQ-18-EHPD\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eACiQ 1.5 Ton Central Ducted Air Handler\u003c\/strong\u003e – Model: \u003cstrong\u003eACIQ-18-AHD\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Kit\u003c\/strong\u003e (sold separately;

At its heart is the ACIQ-18-EHPD inverter condenser, which continuously adjusts compressor speed to precisely match heating or cooling demand, eliminating short-cycling and minimizing energy waste. Paired with the ACIQ-18-AHD multi-positional air handler—capable of upflow, downflow, or horizontal installation—this system seamlessly integrates into your existing ductwork for uniform temperature control throughout your home.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional fixed-speed heat pumps, this system’s “learning condenser” feature gathers ambient and duct conditions during initial startups and refines its operating curves over time. The result is a self-optimizing unit that delivers reliable performance even in extreme climates, operating efficiently down to –13°F in cooling mode and as low as 5°F in heating mode. With a robust gold-fin coil coating, enhanced sensors, and soft-start circuitry, the ACiQ system not only maximizes comfort but also extends component life and reduces maintenance needs.\u003c\/p\u003e\n\u003cp\u003eBacked by a 12-year compressor warranty and 7-year parts coverage (with online registration), the ACiQ 1.5 Ton system represents a smart investment in long-term reliability and lower utility bills. Whether you’re retrofitting an older home or equipping a new construction, this high-efficiency heat pump delivers whisper-quiet operation (34–55 dBA), flexible installation options, and compatibility with any standard 24 V thermostat—making it an ideal choice for homeowners seeking both performance and peace of mind.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eHow is it different from a traditional heat pump?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVariable BTU Inverter: Automatically adjusts output to match demand.\u003c\/li\u003e\n\u003cli\u003eSmart system with soft startups: Maximizes efficiency and reduces energy waste.\u003c\/li\u003e\n\u003cli\u003eSized for heating: Allows you to size for heat without worrying about short cycling in cooling mode.\u003c\/li\u003e\n\u003cli\u003eRated for efficient heating: Operates down to 5°F outdoor temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eQuick Facts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVariable output based on demand: 12,000–18,000 BTU for cooling and heating\u003c\/li\u003e\n\u003cli\u003eRefrigerant: R454B\u003c\/li\u003e\n\u003cli\u003eInverter heat pump system for ducted applications\u003c\/li\u003e\n\u003cli\u003eEfficient cooling from –13°F to 122°F outdoor temperatures\u003c\/li\u003e\n\u003cli\u003eReliable heating from –13°F to 75°F outdoor temperatures\u003c\/li\u003e\n\u003cli\u003eDurable gold-fin condenser coil coating for longevity\u003c\/li\u003e\n\u003cli\u003eQuiet operation, even under high workloads (34–55 dBA)\u003c\/li\u003e\n\u003cli\u003e1.5 Ton, 18.8 SEER2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse our sizing calculator (\u003ca href=\"https:\/\/southminisplits.com\/pages\/sizing-calculator\" target=\"_blank\"\u003eHERE\u003c\/a\u003e) to determine the demand for your home.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eIncluded in Your Order:\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eACiQ 1.5 Ton Inverter Condenser\u003c\/strong\u003e – Model: \u003cstrong\u003eACIQ-18-EHPD\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eACiQ 1.5 Ton Central Ducted Air Handler\u003c\/strong\u003e – Model: \u003cstrong\u003eACIQ-18-AHD\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Kit\u003c\/strong\u003e (sold separately;

ACiQ 1.5 Ton 18.8 SEER2 High Efficiency Central Heat Pump | Inverter - R454B & ACiQ 1.5 Ton Central Ducted Air Handler - R454B

Overview

The ACiQ 1.5 Ton Heat Pump System combines cutting-edge inverter technology with robust build quality to deliver year-round comfort and exceptional energy savings. At its heart is the ACIQ-18-EHPD inverter condenser, which continuously adjusts compressor speed to precisely match heating or cooling demand, eliminating short-cycling and minimizing energy waste. Paired with the ACIQ-18-AHD multi-positional air handler—capable of upflow, downflow, or horizontal installation—this system seamlessly integrates into your existing ductwork for uniform temperature control throughout your home.

Unlike traditional fixed-speed heat pumps, this system’s “learning condenser” feature gathers ambient and duct conditions during initial startups and refines its operating curves over time. The result is a self-optimizing unit that delivers reliable performance even in extreme climates, operating efficiently down to –13°F in cooling mode and as low as 5°F in heating mode. With a robust gold-fin coil coating, enhanced sensors, and soft-start circuitry, the ACiQ system not only maximizes comfort but also extends component life and reduces maintenance needs.

Backed by a 12-year compressor warranty and 7-year parts coverage (with online registration), the ACiQ 1.5 Ton system represents a smart investment in long-term reliability and lower utility bills. Whether you’re retrofitting an older home or equipping a new construction, this high-efficiency heat pump delivers whisper-quiet operation (34–55 dBA), flexible installation options, and compatibility with any standard 24 V thermostat—making it an ideal choice for homeowners seeking both performance and peace of mind.

How is it different from a traditional heat pump?

Variable BTU Inverter: Automatically adjusts output to match demand.
Smart system with soft startups: Maximizes efficiency and reduces energy waste.
Sized for heating: Allows you to size for heat without worrying about short cycling in cooling mode.
Rated for efficient heating: Operates down to 5°F outdoor temperatures.
