Product Details

ACiQ 3 Ton 17.4 SEER2 Central Heat Pump Inverter Extreme Heat Series R454B ACIQ-36-HPD

ACiQ 3 Ton Inverter Heat Pump – Extreme Heat Series (Model ACiQ-36-HPD) The ACiQ-36-HPD delivers 12,000–37,000 BTUs of efficient, variable heating and cooling—even in extreme weather. With advanced inverter technology, a self-learning condenser, and adaptive sizing, it ensures optimal comfort and performance year-round. Designed to handle temperatures as low as -22°F, it offers 100% heating at 0°F and maintains 80% at -22°F—cutting winter energy costs by up to 75%. Features R454B refrigerant, quiet operation, and a durable gold fin coil for long-lasting reliability.

ACiQ-36-HPD 3 Ton Extreme Series Central Inverter Heat Pump – Key Features

  • Inverter-Driven Efficiency: Converts AC to DC power for precise variable-speed compressor control, providing 12,000–36,000 BTU cooling and up to 37,000 BTU heating. The system adapts in real-time to changing weather for consistent indoor comfort and energy savings.

  • Smart Learning Condenser: Equipped with advanced sensors that monitor indoor and outdoor temperatures, duct pressure, and refrigerant conditions. During initial startup, the system “learns” your home’s needs, optimizing future operations automatically.

  • Adaptive Sizing for Seasonal Comfort: The inverter adjusts system output based on load demands, preventing overcooling in summer when the system is sized for winter heating ideal for year-round balance and efficient humidity control.

  • Extreme Heat Technology for Cold Climates: Unlike traditional heat pumps that struggle below 30°F, the ACiQ-36-HPD delivers full heating capacity at 0°F and maintains 80% output at -22°F reducing reliance on electric backup heat and lowering winter energy bills by up to 75%.

  • Year-Round Performance in Any Weather: Operates efficiently from -22°F to 122°F in cooling mode and from -22°F to 75°F in heating mode—engineered to handle extreme temperatures with ease.

  • Environmentally Friendly R454B Refrigerant: Uses R454B refrigerant, which has a significantly lower global warming potential (GWP) than older refrigerants—great for homes looking to future-proof their HVAC system.

  • Gold Fin Condenser Coil Protection: Features corrosion-resistant gold fin coil coating that improves durability and extends the system’s service life, even in coastal or high-humidity areas.

  • Ultra-Quiet Operation: Designed for whisper-quiet performance, even under heavy load, making it a great choice for both residential and light commercial spaces.

  • Ducted HVAC Compatibility: Built for easy integration into existing ducted systems, making it a smart and seamless upgrade from older central HVAC units.

Installation and Maintenance
The installation process for the ACiQ Extreme+ central ducted air handler is similar to that of other replacement air handlers. Your technician will handle electrical, refrigerant, thermostat, and communication connections, as well as link the air handler to the return and supply ductwork. This air handler is multi-positional (upflow, downflow, or horizontal) and features a narrower cabinet design, offering greater versatility and easier installation compared to other models. It is compatible with any 24v thermostat that supports two stages of heating. For colder days, supplemental electric heat kits are available as a backup heat source.

If maintenance is needed, the air handler’s intelligent control board will display fault codes to help diagnose any issues with the system.

Important Note: For proper function, the air handler must be installed with a condenser and other required installation equipment, which may incur additional costs if not included in the product bundle. Additionally, an electric heat kit is required for straight electric heating and is also available at an extra cost.

Impressed by the quality

I’ve installed Goodman heat pumps before at a similar price point. This was better quality, and a great deal from the HVAC store. I’m always a little nervous about picking the lowest cost provider but the came through quick and no damage.

I’m in the middle of install so if you don’t see an update, things went well. As I said, first impressions as I opened it up to adjust airflow direction was very impressed!

A good store to shop for HVAC supply

The store did some things I didn't believe the manager was very helpful in fixing my problem

very reliable company and great prices

Bought a few units from this company and they were very friendly and easy to work with. Either matched prices or beat the price and had fast shipping also.

Excellent company to purchase from

I wasn’t to sure about if this company could deliver it quickly but it arrived within a week. No issues. I needed this one for parts as my first one that I installed a year ago had the ecm go out on the blower fan. Parts are hard to come by for this Chinese brand. I think the ecm went out due to condensation in the main supply plenum dripping onto fan motor. I do like this ac unit but hope the fan lasts longer than a year. I covered the fan ecm with flex seal tape.

Goodman 5 Ton System

Excellent value, customer sales support (a human called to confirm online order... greatly appreciated!), fast shipping. Very happy customer.

A + Company

Great price, communication and service I will be buying another furnace from them Fantastic !

Sale representative Lopez was very experienced and professional. I would recommend this company to any one and I am looking forward to work with Lopez again.
