// Bottom Line
This ACiQ horizontal cased coil works best for contractors building complete systems on a budget or homeowners replacing failed coils in existing installations. The 14 SEER rating delivers solid mid-range efficiency without premium pricing, and the 10-year warranty adds confidence to the purchase.

Review

The ACiQ 2 ton horizontal 21-inch cased coil sits squarely in the practical middle of the residential AC market. This is genuine Goodman engineering under the ACiQ brand, meaning you get proven reliability without boutique pricing. The unit delivers 24,000 BTU of cooling capacity with a 14 SEER rating, making it suitable for small homes, apartments, or secondary cooling zones in larger properties. It's the kind of equipment contractors reach for when balancing performance requirements with project budgets.

The coil operates on R454B refrigerant, the modern drop-in replacement that avoids the phase-out issues plaguing older systems. At 71 dB, the single-stage rotary compressor runs audibly during peak cooling but not excessively. Electrical requirements are straightforward: 208/230V single-phase at 60 Hz with a 25-amp maximum breaker and 14.3-amp minimum. The 3/8-inch liquid line and 3/4-inch suction line with included 3/4-inch insulation follow industry-standard sizing for proper refrigerant flow and efficiency.

Pros & Cons

Pros

  • 24,000 BTU capacity with 14 SEER efficiency rating balances performance and operating costs
  • R454B refrigerant is modern, widely available, and more environmentally responsible than older alternatives
  • 10-year warranty with online registration covers manufacturing defects comprehensively
  • Single-stage rotary compressor is proven reliable across thousands of residential installations
  • Standard 208/230V single-phase electrical simplifies installation in typical homes

Cons

  • Not Energy Star certified, so no utility rebates or tax credits available in most regions
  • 71 dB noise level is moderate to high, noticeable from nearby outdoor areas
  • Listed tonnage confusion: labeled as 3.5 ton but marketed as 2 ton creates specification ambiguity

Frequently Asked Questions

Why does the spec say 2 ton but the tonnage field shows 3.5 ton? +
This is confusing labeling from the manufacturer. The 24,000 BTU capacity equals approximately 2 tons of cooling. The 3.5 ton rating appears to be a data entry error or refers to condenser matching requirements. Contact ACiQ directly if specifications matter for your system matching.
Can I install this myself if I'm handy? +
Possible but not recommended without EPA certification and proper tools. Refrigerant handling requires evacuation and charging equipment. Improper installation voids warranty and creates safety hazards. Hire a licensed HVAC technician for permanent, reliable installation.
How does 14 SEER compare to newer high-efficiency units? +
14 SEER is solid mid-range efficiency. Newer models achieve 16-18 SEER, reducing operating costs 15-25 percent. However, 14 SEER meets minimum efficiency standards nationwide and delivers excellent value for budget-conscious buyers.
Is R454B safe and widely available for future service? +
Yes. R454B is EPA-approved, non-ozone-depleting, and increasingly stocked by HVAC suppliers nationwide. It's the mainstream refrigerant for new residential systems, ensuring parts and service availability for the next 10-15 years.
What does the 10-year warranty actually cover? +
Manufacturing defects in the coil and compressor, including refrigerant leaks and mechanical failure. Parts are replaced free with registration. Labor and Freon are typically not covered. Read the full warranty document before purchase.
