About this system
The ACiQ EVD5X48M24A is a 4-ton, 24-inch wide V-coil evaporator coil designed for residential split-system air conditioning. It is factory-charged for R-454B, the low-global-warming-potential refrigerant that is replacing R-410A across the industry, so it is ready for pairing with modern R-454B-compatible outdoor condensing units. The TXV (thermostatic expansion valve) is included from the factory, which improves part-load efficiency and refrigerant metering compared to fixed-orifice alternatives, and the 24-inch width makes it a practical fit for common residential air handler and furnace cabinets where space is a constraint.
This coil is a straightforward replacement or new-installation component rather than a complete system, so it is relevant to contractors and DIY-capable homeowners who are assembling a matched split system or upgrading an existing air handler to handle R-454B refrigerant. The V-coil configuration maximizes surface area within a compact footprint, supporting efficient heat exchange at the 4-ton capacity level. Because it ships direct from ACiQ without dealer markup, the upfront cost typically undercuts equivalent coils from name-brand lines, making it an appealing option for budget-conscious builds where a certified installer is handling the refrigerant work regardless.
The EVD5X48M24A is a competitively priced R-454B-ready evaporator coil that covers the fundamentals well, including a factory TXV and a 12-year warranty, at a cost below most name-brand equivalents. The trade-offs are the same ones that follow the ACiQ brand generally: the actual manufacturer is undisclosed, long-term coil reliability data is thin, and service depends entirely on independent contractors. For price-sensitive builds where a qualified installer is already in the picture, it is a reasonable choice; for buyers who want brand-name parts cross-referencing and a deep service network, established alternatives are safer.
Overall score is the average of the five ratings above.
What we like
- R-454B compatibility future-proofs the system against the ongoing phase-out of R-410A
- Factory-installed TXV improves efficiency and refrigerant control versus fixed-orifice coils
- V-coil configuration fits 24-inch wide cabinets while delivering full 4-ton heat-exchange area
- Direct-sale pricing undercuts comparable coils from Carrier, Trane, and Lennox lines
- 12-year parts warranty with registration is strong coverage for a value-tier component
Trade-offs
- The undisclosed manufacturer makes parts cross-referencing and service history harder to verify than with name-brand coils
- Long-term coil reliability data is limited because ACiQ is a newer brand with no Consumer Reports ranking yet
- No dealer network means service and warranty claims depend entirely on finding a willing independent contractor
- As a coil-only component it requires compatible R-454B air handler and outdoor unit selection, adding system-assembly complexity
What homeowners and pros say about ACiQ
Among the homeowners and contractors who have shared early impressions of ACiQ equipment, the recurring themes are quiet operation, solid build quality out of the box, and a customer support team that responds without the runaround common with larger brands. Consumer Reports has not yet assigned ACiQ a reliability score because the brand is too new to have the long-term data that rating requires, and that absence is worth taking seriously when evaluating a coil that is expected to last 15 or more years inside a system. The undisclosed original manufacturer is the sticking point that comes up most often in HVAC contractor forums, not because the hardware appears poor, but because it makes cross-referencing parts and pulling service history harder than it is with a Carrier or Trane coil where provenance is documented.
For this specific coil, the failure modes most worth watching are the ones that apply to evaporator coils broadly and to newer brands in particular: coil leaks at the joints or along the tubing are the most consequential issue with any evaporator coil over time, and without a long track record it is not yet clear how ACiQ coils hold up over a decade of thermal cycling and condensate exposure. Service access is the other real-world concern, since ACiQ sells direct and has no dealer network, meaning warranty work relies entirely on finding an independent contractor willing to work with the brand. For buyers who go in with eyes open on those trade-offs, the direct-sale pricing and the factory-included TXV make this coil a legitimate contender in a 4-ton R-454B build.

| ACiQ | EVD5X48M24A | N/A (coil only) | N/A (coil only) | Value pick |
| Carrier | Performance Series CNPVP4821ALA (or equivalent 4-ton R-454B cased coil) | N/A (coil only) | N/A (coil only) | Moderately higher than ACiQ |
| Trane | 4TXCB003DS3 series 4-ton uncased coil | N/A (coil only) | N/A (coil only) | Higher than ACiQ, typically mid-to-premium tier |
| Lennox | CH35 series 4-ton cased coil | N/A (coil only) | N/A (coil only) | Higher than ACiQ, premium pricing through dealer channel |

Questions about this system
Will this coil work with my existing R-410A outdoor unit?
No. The EVD5X48M24A is designed and factory-configured for R-454B refrigerant, which is not interchangeable with R-410A. Pairing it with an R-410A condenser would require a full system replacement on the outdoor side as well.
Does the TXV come pre-installed, or do I need to source and fit one separately?
The TXV is factory-installed on this coil, so your installer does not need to purchase or fit a separate metering device. This is a meaningful convenience and cost saving compared to some value-tier coils sold without one.
How do I register the 12-year warranty, and what does it actually cover?
Warranty registration is done through ACiQ's website after purchase. The 12-year coverage applies to parts; labor costs are not included, so budgeting for a service call is still necessary if a warranty repair is needed down the line.
Because the manufacturer is not publicly disclosed, can I still get replacement parts if something fails?
ACiQ supplies parts through its own direct channel, so you are not sourcing from a third-party parts network. The practical concern is that without knowing the original equipment manufacturer, a local HVAC parts house may not be able to cross-reference components, making you dependent on ACiQ directly for replacements.
Is a 24-inch wide coil the right fit for a standard residential furnace or air handler cabinet?
The 24-inch width is a common residential dimension, but you should confirm the cabinet opening and coil height clearance of your specific air handler before ordering. V-coil height varies by tonnage, and a 4-ton coil is taller than smaller-tonnage equivalents, so measure the available vertical space in your cabinet carefully.
