About this system
The ACiQ R5A4S18AKANA is a 1.5-ton, cooling-only condensing unit rated at 13.4 SEER2, designed to pair with a separately purchased air handler or coil in a split-system setup. At 1.5 tons, it is sized for smaller spaces, typically 450 to 700 square feet depending on your climate, insulation quality, and local heat load. The R-454B refrigerant it uses is a lower-global-warming-potential alternative to R-410A, and it meets the Department of Energy’s 2023 regional efficiency minimums, so you are buying a system that is compliant for new installations across all U.S. climate regions.
This is a single-stage, cooling-only condenser, meaning it runs at one speed and provides no heating. If your home already has a gas furnace or separate heat source, that is no issue, but buyers expecting a heat pump should look elsewhere. The 13.4 SEER2 rating lands at the regulatory baseline for many regions, which keeps the upfront cost down but means you will not see the utility savings that a higher-SEER2 or variable-speed unit would deliver over time. It suits homeowners who want straightforward, code-compliant cooling without paying a premium for efficiency headroom they may not recoup in a smaller, less-used space.
The ACiQ 1.5-ton 13.4 SEER2 condenser is a no-frills, budget-conscious option that clears the regulatory efficiency bar and carries a strong 12-year warranty for the price. It is a reasonable fit for a small, secondary space or a budget replacement where long-term efficiency payback matters less than low upfront cost. Because the brand is still building a long-term reliability record and service is handled through independent contractors, buyers who want established data or a local dealer network will find more confidence with a legacy brand.
Overall score is the average of the five ratings above.
What we like
- Price undercuts most name-brand equivalents at the same efficiency tier
- 12-year parts warranty ships standard without dealer markup inflating the cost
- R-454B refrigerant is forward-compatible with tightening EPA regulations
- Single-stage design keeps installation straightforward for most certified contractors
- Early owner feedback points to quiet operation and responsive factory support
Trade-offs
- 13.4 SEER2 is the regulatory floor, not a high-efficiency unit, so utility savings over a better-rated system are real over time
- Cooling only, so it cannot replace a heat pump and requires a separate heating system
- Undisclosed manufacturer makes parts cross-referencing and long-term service history harder to verify
- No dealer network means service coordination falls entirely on the homeowner finding a willing independent contractor
What homeowners and pros say about ACiQ
Homeowners who have installed ACiQ equipment generally report satisfaction with the out-of-box experience: units arrive well-packaged, run quietly once commissioned, and the factory support line gets reasonably good marks in early Google and dealer review aggregates. The 12-year parts warranty without dealer markup is a recurring positive note, since most buyers coming from a name-brand quote are startled by how much of that quote was margin rather than hardware. That said, owners and forum contributors are quick to flag the service reality: because ACiQ is sold direct and the manufacturing origin is not confirmed, a contractor who has never touched the brand may be slower to diagnose an issue or locate a part, and that friction shows up in scattered complaints about repair delays rather than the equipment itself.
On the professional side, independent HVAC technicians who have commissioned ACiQ condensers tend to describe the hardware as familiar-feeling, which feeds the ongoing forum speculation about ICP and Carrier family origins. The concern most pros raise is not build quality on day one but the long-term unknowns: Consumer Reports has not yet ranked the brand due to insufficient data, and the specific failure modes that plague any residential condenser over a decade, such as capacitor degradation, coil leak development, and compressor longevity, remain uncharted territory for ACiQ because the brand simply has not been in the field long enough to produce independent actuarial data. For a small, low-use application on a tight budget, most contractors will install one without objection; for a primary system in a high-run-hour climate, many will still steer clients toward a brand with a longer service record.

What it costs to run
At 13.4 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 $274 per year in cooling, about $0 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 ÷ 13.4 SEER2) × 1200 hours ÷ 1000 × $0.17/kWh. Rate source: U.S. EIA average; cooling hours: moderate-climate estimate.

| Brand | Comparable model | SEER2 | Stage | Price position |
|---|---|---|---|---|
| ACiQ | R5A4S18AKANA | 13.4 | Single-stage | Value pick |
| Carrier | Comfort 13 (24ACC3) | 13.4 | Single-stage | Moderately higher than ACiQ, reflects dealer and brand premium |
| Trane | XR13c | 13.4 | Single-stage | Moderately to noticeably higher than ACiQ through dealer channels |
| Lennox | Merit ML14XC1 | 14.3 | Single-stage | Noticeably higher than ACiQ, with incremental efficiency gain |

Questions about this system
Will this condenser work with my existing R-410A air handler or coil?
No. R-454B and R-410A systems are not cross-compatible because the refrigerants require different pressure ratings and, in many cases, different oil and component tolerances. You will need a matched R-454B-rated evaporator coil or air handler; confirm compatibility with ACiQ or your contractor before purchasing.
Does this unit include a heat pump, or is it cooling only?
It is strictly a cooling-only condensing unit. There is no reversing valve and no heating capability. If you need year-round comfort from a single outdoor unit, you will need to choose a heat pump model instead.
Who actually manufactures ACiQ equipment, and does it matter for parts availability?
ACiQ is AC Direct's house brand and the actual manufacturer is not publicly disclosed, with unconfirmed forum speculation pointing to the ICP and Carrier family. It matters in practice because independent technicians cannot easily cross-reference parts or service bulletins to a known parent line, so sourcing replacement components may take longer than with a brand whose factory origin is transparent.
How does the 12-year warranty work if there is no dealer network?
ACiQ's 12-year parts warranty is registered directly with the brand and does not depend on a dealer. Labor, however, is not covered, so you will need to hire and pay an independent licensed HVAC contractor for any warranty repair work. Keep all purchase documentation and registration confirmation in case a claim is needed.
Is 13.4 SEER2 going to cost me more in electricity compared to a higher-rated unit?
Yes, a higher-SEER2 unit will consume less electricity for the same cooling output. On a 1.5-ton system in a small space, the absolute dollar difference per year is modest, but over a 15-year system life the gap is real. Whether that difference justifies the higher upfront cost of a 16-plus SEER2 unit depends on your local electricity rates, run hours, and how long you plan to stay in the home.
