Heat That Works When Temperatures Drop Below Zero

Heat That Works When Temperatures Drop Below Zero

Most heat pumps shut down around 17°F and switch to electric resistance heat — a massive power drain that cripples off-grid battery banks. The ACiQ Extreme Series eliminates that vulnerability. Its HyperHeat inverter technology uses variable refrigerant flow and outdoor temp sensing to extract heat down to -22°F. An integrated base pan heater prevents ice buildup on the condenser coil. At Off Grid Vault, we vet every product for grid-independent performance — this condenser delivers rated heating in conditions where competitors fail. That means your battery bank stays sized for normal operation, not emergency backup strips.

Lower Energy Draw Means a Smaller Solar Investment

Lower Energy Draw Means a Smaller Solar Investment

At 22.2 SEER2, this system pulls significantly fewer watts per BTU than standard mini splits. The variable inverter twin rotary compressor continuously adjusts output to match your actual load instead of cycling on and off at full power. For off-grid homeowners, that efficiency translates directly into reduced battery capacity requirements and fewer solar panels. Over a 10-year service life, the energy savings are substantial compared to lower-SEER alternatives. Register at ACiQ.com to activate the 7-year parts and 12-year compressor warranty — long-term reliability that matches the long-term economics.

Two Zones, Two Temperatures, Zero Wasted Energy

Two Zones, Two Temperatures, Zero Wasted Energy

This system includes two 18,000 BTU wall-mounted air handlers connected to a single 3-ton condenser. Each zone operates independently — set your bedroom to 68°F while the living room holds 72°F, or shut down unused rooms entirely. The adaptive technology in each air handler continuously monitors and maintains your setpoint. Self-diagnosing control boards send error alerts to each handler's display and to your smartphone via the NetHome Plus app. The condenser supports up to four handlers total, so you can expand later without replacing outdoor equipment.

36,000 BTU 22.2 SEER2 ACiQ 2-Zone Wall Mounted Mini Split System – Extreme Series – WiFi Enabled – 18+18

ACiQ offers a smart, cost-effective solution for adaptive heating and cooling in nearly any space and climate. With the ACiQ-36Z-HH-M4, you can connect up to four air handlers to a single condenser, maximizing outdoor space while ensuring total home comfort.

This 36,000 BTU system is designed to efficiently support up to 45,000 BTU across all air handlers, thanks to its advanced inverter technology that continuously adjusts to provide precise heating and cooling. Enjoy customized comfort by setting different temperatures in each room or turning off heating and cooling in unused areas—helping you save energy without sacrificing comfort.

With a 21.5 SEER efficiency rating, this system is engineered for long-term savings both upfront and over its lifetime. While the condenser comes pre-charged, please note that this model does not include quick-connect line set connectors and is not a self-install unit. A professional technician is required for installation, including vacuuming the lines and adding refrigerant as needed.

Installation materials such as line sets, control wire, drain hose, whip, and disconnect are not included but are available for purchase in the Accessories section. Additionally, all multi-zone ACiQ condensers require a minimum of two air handlers to function properly.

ACiQ 18,000 BTU 22.9 SEER2 2-Zone Features

  • Extreme Heat Base Pan Heater Technology: Each ACiQ condenser has integrated Extreme Heat technology to maximize heat performance in extreme cold weather. Extended heat pump performance (HyperHeat) harnesses the power of inverter condenser with outdoor temp sensing, variable refrigerant flow and variable condenser fan speed to maximize heat extraction all the way down to -22°F. Plus, every Extreme Heat ACiQ condenser includes a base pan heater to keep ice from collecting on the condenser coil during heat pump operation.
  • Quality Construction: State-of-the-Art manufacturing is behind every ACiQ product, resulting in quiet, effective operation over a long service life. Most models have low ambient heating and cooling.
  • Highest Efficiency: ACiQ saves you money up front, but also over time by reducing energy bills. Every ACiQ condenser features a variable inverter twin rotary compressor, lowering wear and increasing performance. Compare specs against other brands in the same price category, and you will agree, ACiQ is the best value.
  • Longer life, longer warranty: Intelligent design goes into every element of ACiQ’s manufacturing ensuring flawless performance for years. Low friction, variable inverter twin rotary compressors give bulletproof reliability. Register equipment at ACiQ.com to extend warranty protection to 7 years parts, 12 years compressor.
  • Installation and Maintenance: ACiQ multi zone condensers are pre-charged with R410-A refrigerant for 25′ per air handler connection. In many cases, no additional refrigerant is needed. All units are run-tested at the factory for years of trouble-free performance. Troubleshooting is easy thanks to unit’s self diagnosing control board with alerts that are sent to each connected air handler.
  • Platinum Performance: ACiQ Platinum air handlers can be used with any ACiQ Multizone condenser or the Platinum Single Zone condenser to create a highly efficient, Hyper Heat system. This air handler can handle small to medium sized rooms using adaptive technology to constantly monitor and maintain your ideal temperature no matter what the weather outside.
  • Intelligent Heating and Cooling: The ACiQ-18W-HH-MB air handler includes a soft LED display on the front of the unit giving you information at a glance. The display shows room temperature by default but can also show temperature setpoint changes and mode changes. To ensure your unit runs properly throughout its lifetime, this display will also show any error codes from its self-diagnosing control board. The display can be switched off if desired, and the included smart remote has a built-in LCD display to show these notifications as well.
  • WiFi Options: ACiQ is WiFi ready! The wall mounted air handlers come with everything you need to control your home’s heating and cooling via smart device (iOS or Android) from anywhere in the world. ACiQ is also compatible with Amazon Alexa and Google Assistant. Please note that in order to function, this air handler must be installed with a condenser and other installation equipment, available at an additional cost if not already included in this product bundle.
  • Wall Mounted: Traditional wall-mounted air handlers are the most popular ductless choice due to low cost and ease of installation. Wall mounted units are located high on an outside wall, with refrigerant lines and condensation drain hose exiting the back through a 3″ wall penetration. Return air is brought in through vents in the top of the unit, and cooled or heated air exits the lower front through a sweepable louver. Wall mounted air handlers are WiFi compatible and can be controlled by the free NetHome Plus app or by voice assistants such as Alexa or Google Home.
  • Smartphone App: In addition to the handheld or wired remote that is already included, wall mounted units are WiFi ready, and can be controlled from anywhere with a free app on your tablet or smartphone.
  • Quiet Comfort: Every ACiQ system is precision engineered to quickly achieve set temperature and hold it there, no matter what the weather is outside. With whisper quiet indoor and outdoor units, ACiQ never intrudes on your peace and quiet.
