About this system
The ACiQ R5A5S18AKAWA is a 1.5-ton, cooling-only condensing unit rated at 14.3 SEER2, designed to pair with a separately purchased air handler or evaporator coil in a split-system setup. At 1.5 tons, it is sized for smaller spaces, typically homes or additions in the 600 to 900 square foot range depending on local climate, insulation quality, and ceiling height. The R-454B refrigerant is a low-global-warming-potential replacement for R-410A, meaning this unit complies with current EPA regulations and is positioned for the coming years of refrigerant transition, though it also means your installing contractor must have equipment certified for the new refrigerant.
ACiQ is AC Direct’s house brand, priced to undercut established names while reportedly sharing manufacturing roots with a major OEM, though that parent company is not publicly confirmed. For a buyer who is comfortable purchasing direct, managing their own contractor relationship, and accepting a newer brand’s track record in exchange for a lower upfront cost, this condenser offers a federally compliant efficiency tier and a 12-year warranty that rivals or exceeds what name-brand dealers typically offer after markup. It is a straightforward single-stage cooling unit, so it runs at full capacity whenever it is on, which suits climates with relatively uniform hot-weather demand rather than regions that need the fine humidity control of a variable-speed or two-stage system.
The ACiQ 1.5-ton 14.3 SEER2 condenser is a competent entry-level cooling unit that earns its place on price and warranty length, but the brand is new enough that long-term reliability data is genuinely thin. Buyers trading a familiar nameplate for direct-buy savings need to be prepared to source their own qualified contractor and accept some uncertainty that an established brand simply does not carry.
Overall score is the average of the five ratings above.
What we like
- Lower purchase price than comparable name-brand condensers at the same efficiency tier
- 12-year parts warranty included without dealer markup inflating the coverage cost
- R-454B refrigerant puts the unit on the right side of current and near-future EPA regulations
- Early owner feedback consistently notes quiet operation and responsive customer support from AC Direct
- Factory-direct purchasing removes the middleman margin common with dealer-sold brands
Trade-offs
- Consumer Reports does not yet rank ACiQ, so independent long-term reliability data does not exist
- Undisclosed manufacturer makes cross-referencing parts, service bulletins, and failure history difficult for technicians
- No dealer network means you are fully responsible for finding and vetting your own licensed installer
- Single-stage operation means the unit cycles on at full capacity, which is less efficient at managing humidity in hot-humid climates than two-stage or variable-speed alternatives
What homeowners and pros say about ACiQ
Homeowners who have gone through the direct-buy process with ACiQ units tend to highlight two things consistently: the out-of-pocket cost is genuinely lower than equivalent quotes from local dealers, and AC Direct’s support team is described as responsive when questions come up during and after installation. Quiet operation is a recurring theme in early owner accounts for units in this class. That said, the honest caveat repeated in HVAC forums is that the brand is new enough that nobody can speak with authority to how these systems hold up at the 8 to 12 year mark, which is exactly when compressor wear and coil integrity tend to reveal themselves. Consumer Reports has not yet assigned ACiQ a reliability score due to insufficient long-term field data, and that absence is meaningful rather than dismissible.
Among HVAC technicians, the most commonly noted friction point is the undisclosed manufacturer. Without a confirmed OEM identity, a technician encountering an unfamiliar failure cannot easily cross-reference service bulletins, known failure modes, or compatible parts from a sister brand. The documented structural concerns for the brand broadly are the same ones that apply here: parts sourcing transparency is limited compared to Carrier, Trane, or Lennox units with fully public supply chains, and because installation is handled entirely through independent contractors rather than a certified dealer network, the quality of the install itself varies more than it would with a brand that trains and vets its own service channel. The 12-year parts warranty is a genuine strength on paper, but its practical value depends on AC Direct remaining a going concern and on having a competent contractor available to perform the work.

What it costs to run
At 14.3 SEER2, cooling this 1.5-ton system for a typical 1200-hour cooling season at the U.S. average electricity rate of $0.17/kWh works out to roughly $257 per year in cooling, about $17 less per year than a minimum-efficiency 13.4 SEER2 unit of the same size. Your real cost depends on your climate and local rate.
Method: (18,000 BTU/hr ÷ 14.3 SEER2) × 1200 hours ÷ 1000 × $0.17/kWh. Rate source: U.S. EIA average; cooling hours: moderate-climate estimate.
How it compares
| Brand | Comparable model | SEER2 | Stage | Price position |
|---|---|---|---|---|
| ACiQ | R5A5S18AKAWA | 14.3 | Single-stage | Value pick |
| Carrier | Comfort 24ACC4 Series | 14.3 | Single-stage | Noticeably higher, includes dealer network and established service infrastructure |
| Trane | XR14c Series | 14.3 | Single-stage | Higher than ACiQ, reflecting brand premium and dealer distribution costs |
| Lennox | Merit ML14XC1 Series | 14.3 | Single-stage | Higher than ACiQ, backed by Lennox dealer network with corresponding markup |

Questions about this system
Will any licensed HVAC contractor be able to install this unit, or does it require a factory-authorized technician?
Any licensed HVAC contractor can install it, but because ACiQ is sold direct rather than through a dealer network, you will need to find and hire that contractor independently. Make sure the technician has equipment certified for R-454B refrigerant, since it requires different handling tools than the older R-410A.
What air handler or evaporator coil does this condenser need to match with?
This is a cooling-only condenser, so it requires a separately purchased, compatible air handler or uncased evaporator coil rated for 1.5-ton capacity and confirmed to work with R-454B refrigerant. ACiQ sells matching air handlers direct, and your contractor can verify coil compatibility before purchase to protect the warranty.
How does the 12-year warranty actually work when there is no dealer to handle claims?
The 12-year parts warranty is registered directly through ACiQ or AC Direct at the time of installation. Claims are handled through AC Direct's support channels rather than a local dealer, and a contractor you hire performs the covered repair using warranted parts. Getting clear written documentation of the warranty registration process at installation is worth the extra step.
Is 14.3 SEER2 going to cost me more to run than a higher-efficiency unit, and is it worth upgrading?
14.3 SEER2 meets the current federal minimum for most regions and will run more efficiently than an older 10 to 13 SEER unit it might be replacing, but it will consume more electricity than a 16 or 18 SEER2 system over the same cooling hours. For a 1.5-ton unit in a smaller space with moderate seasonal use, the payback period on a higher-efficiency upgrade can be quite long, so the entry-level tier is often practical.
Since the actual manufacturer is not disclosed, how hard will it be to find replacement parts down the road?
This is a legitimate concern. If forum speculation about manufacturing ties to the ICP or Carrier family turns out to be accurate, component overlap may make parts easier to source, but that is unconfirmed. The 12-year parts warranty covers the most vulnerable window, and ACiQ has stated it supports the units it sells, but the lack of a transparent supply chain is a real trade-off compared to brands with fully public parts networks.
