// Bottom Line
This ACiQ vertical cased coil is an excellent choice for contractors building budget systems or homeowners replacing aging equipment without premium pricing. The 14 SEER rating delivers solid efficiency for the cost, and the compact 21-inch width fits most standard air handler cabinets.

Review

The ACiQ 2.5-ton (3.5-ton actual) vertical cased coil represents solid midmarket positioning in the HVAC replacement segment. This 21-inch wide A-coil configuration works with both upflow and downflow air handlers, making it a versatile choice for retrofit applications. The unit ships with pre-insulated suction lines and standard refrigerant connections, reducing field preparation time for trained technicians.

Performance metrics show this coil operating at 14 SEER1 efficiency using R454B refrigerant, delivering 30,000 BTU cooling capacity with single-stage operation. The rotary compressor draws between 17.1 and 25 amps at 208/230V single-phase power, fitting standard residential electrical infrastructure. At 72 dB, noise levels are acceptable for outdoor placement, though not as quiet as variable-capacity alternatives in the 68-70 dB range.

Pros & Cons

Pros

  • 14 SEER efficiency rating provides good energy performance for the price point
  • 30,000 BTU capacity covers 3.5-ton systems effectively
  • Compact 21-inch width fits standard upflow and downflow air handlers
  • R454B refrigerant is newer, lower-GWP option meeting future regulations
  • 10-year warranty with online registration covers manufacturing defects
  • Rotary compressor design offers reliability in residential applications

Cons

  • Single-stage compressor means less precise temperature control than two-stage systems
  • 72 dB noise level is slightly higher than premium variable-capacity units
  • Not Energy Star certified, limiting rebate eligibility in some regions

Who Should Buy

Best For

Contractors building mid-range systems for residential replacements will appreciate the straightforward single-stage design and cost efficiency. Homeowners in moderate climates looking to replace 10-15 year old equipment without spending premium dollars will see solid return on investment.

Consider Alternatives If

Buyers in extreme heat climates or those prioritizing quiet operation should explore higher-stage options, and homeowners seeking Energy Star rebates should verify local programs before purchase.

Installation

Installation is straightforward for experienced HVAC technicians. The unit accepts 3/8-inch liquid and 3/4-inch suction connections with matching 50-foot pre-insulated line sets. Vertical mounting requires standard bracket hardware included with Goodman-compatible air handlers. Vertical clearance of 26 inches and width of 21 inches fit most closet-mounted systems without modification.

Warranty & Reliability

Coverage includes 10 years of parts protection when registered online within 30 days of purchase. This is standard for mid-tier residential equipment but requires proof of purchase and proper installation documentation. Goodman's evaporator coil warranty aligns with this timeline, protecting against manufacturing defects and refrigerant leaks from coil failure.

Frequently Asked Questions

What's the actual tonnage, and why does the title say 2.5 but specs say 3.5? +
The coil handles 30,000 BTU output, which equals 2.5 tons technically. Goodman rates the complete system at 3.5 tons when paired with matching outdoor condenser units. Always verify outdoor condenser specifications match this coil's capacity for proper system balance.
Does this coil work with my existing air handler? +
Yes, if your air handler has a 21-inch width cabinet and accepts standard 3/8-inch and 3/4-inch refrigerant lines. The unit fits both upflow and downflow configurations. Check your current coil dimensions and connection sizes before ordering to confirm compatibility.
Is 14 SEER efficient enough, or should I pay more for 16 SEER? +
14 SEER saves 12-15 percent annually versus 10 SEER baseline systems. Two-stage coils reaching 16 SEER cost roughly 20 percent more. For mild climates, this unit justifies the lower cost. High-usage areas benefit more from premium efficiency.
How does R454B refrigerant compare to R410A? +
R454B has lower global warming potential and meets emerging EPA regulations, though R410A remains more common. Systems aren't directly interchangeable. R454B equipment like this future-proofs your installation against regulatory phase-out schedules expected through 2030.
What does the 10-year warranty actually cover? +
Manufacturing defects and component failures including compressor and coil damage. Requires online registration within 30 days. Labor costs and refrigerant aren't included. Coverage protects your investment against premature failure but not normal wear or improper installation.
