About this system
The ACiQ EVD5X61M24A is a 5-ton replacement evaporator coil built around a 24-inch-wide V-coil configuration and factory-installed TXV (thermostatic expansion valve). It is designed for use with the new R-454B refrigerant, a lower-GWP alternative to R-410A that is increasingly standard on new equipment sold after 2025. If your existing outdoor unit has already been upgraded to R-454B or you are installing a matched new system, this coil slots into that lineup as the indoor heat-transfer component that does the actual cooling work inside your air handler or furnace cabinet.
At 5 tons, this coil targets larger homes, typically in the 2,400 to 3,000 square foot range depending on climate and insulation. The V-coil shape packs more surface area into the 24-inch cabinet width than a flat-slab coil would, which improves heat transfer efficiency and keeps static pressure reasonable for the air handler it pairs with. The TXV is a meaningful inclusion at this price point; it meters refrigerant flow precisely as load changes, which protects the compressor from flood-back and keeps the system operating closer to its rated efficiency across partial-load conditions. This coil does not carry a standalone SEER2 rating because efficiency is a system-level figure, but it is engineered to support current high-efficiency ratings when matched with a qualifying outdoor unit.
The ACiQ EVD5X61M24A is a competitively priced, spec-appropriate evaporator coil for installers and homeowners who need a 5-ton R-454B-compatible replacement without paying name-brand premiums. The TXV inclusion and V-coil design are genuine strengths at this price tier, but the brand's limited long-term track record and the undisclosed manufacturer mean you are accepting more uncertainty on parts sourcing and long-term reliability than you would with a Carrier or Trane coil. For a cost-conscious new install or a like-for-like replacement where the contractor is comfortable sourcing ACiQ, the value case is real.
Overall score is the average of the five ratings above.
What we like
- R-454B compatibility future-proofs the installation against refrigerant phase-out timelines
- Factory TXV is a legitimate efficiency and reliability feature, not always standard at this price
- V-coil design delivers better heat-transfer surface area within the 24-inch cabinet constraint
- 12-year parts warranty with no dealer markup is longer and cleaner than many competitors
- Direct-to-consumer pricing undercuts comparable coils from name brands by a meaningful margin
Trade-offs
- Manufacturer identity is not disclosed, making it harder to cross-reference OEM parts or service bulletins
- Long-term coil leak and reliability data is limited because the brand is relatively new to the market
- No national dealer network means repair support depends entirely on finding an independent contractor willing to work with ACiQ equipment
- A standalone coil has no SEER2 rating on its own, so efficiency claims only hold if paired with a qualifying matched outdoor unit
What homeowners and pros say about ACiQ
Homeowners who have replaced aging R-22 or R-410A coils with ACiQ units generally report that the hardware itself feels solid out of the box and that the direct-purchase experience is straightforward. The most common contractor concern is not the coil’s physical quality but the undisclosed manufacturer: when something eventually needs a replacement part, there is no clear OEM lineage to follow, and that can slow down a repair if the part is not in ACiQ’s own supply chain. Consumer Reports has not yet ranked ACiQ due to insufficient long-term field data, so there is no independent reliability score to point to, and early owner feedback, while largely positive on quiet operation and responsive customer support, does not yet reflect the multi-year picture that a coil evaluation really requires.
On the specific failure modes worth watching: coil leaks are the primary risk with any evaporator coil over time, and because ACiQ’s track record is short, there is not yet meaningful failure-rate data to compare against Carrier or Trane. Parts sourcing is the secondary concern; if the undisclosed manufacturer turns out to share components with a major OEM family, that problem largely goes away, but buyers cannot confirm that today. For a 5-ton R-454B installation where upfront cost is the main constraint and the installing contractor is comfortable working with the brand, the ACiQ coil presents a credible option. For installations where long-term serviceability and a known parts chain matter most, the price premium for a name-brand coil buys real peace of mind.

Questions about this system
Will this coil work with my existing R-410A outdoor unit?
No. The EVD5X61M24A is designed for R-454B refrigerant and should not be charged with R-410A. R-454B and R-410A are not interchangeable, and using the wrong refrigerant will void the warranty and can damage the system. If your outdoor unit uses R-410A, you need a coil rated for that refrigerant.
Does the TXV come pre-installed or do I need to add one separately?
The TXV is factory-installed on this model. Your installing contractor does not need to source or add a separate metering device, which simplifies the installation and reduces one potential point of field error.
How do I register for the 12-year warranty, and what does it cover?
ACiQ's 12-year warranty requires product registration through their website within a set window after installation. It covers parts, not labor, so if a component fails after the base coverage period, you still pay the technician's time. Read the warranty terms carefully before purchase and confirm your contractor is aware of the registration requirement.
Can any licensed HVAC technician service this coil, or does it need an ACiQ-authorized dealer?
Any licensed HVAC technician certified to handle R-454B refrigerant can service it. ACiQ does not sell through a traditional dealer network, so there are no authorized-dealer restrictions, but that also means there is no dedicated service network to call if you need help finding a contractor familiar with the brand.
What air handler or furnace cabinet width does this coil fit?
The 24-inch-wide V-coil is designed for matching 24-inch air handler or furnace cabinets. Confirm your air handler's cabinet width and coil connection dimensions against ACiQ's published specs before ordering, because fitting a coil into the wrong cabinet width is a common and costly installation mistake.
