// Bottom Line
This ACiQ coil is ideal for contractors upgrading existing 1.5 ton systems or homeowners seeking a cost-effective replacement without premium pricing. The 13 SEER rating delivers respectable efficiency for standard cooling loads, making it a practical choice for moderate climates where peak performance isn't critical.

Review

The ACiQ 1.5 ton horizontal cased coil occupies a practical middle ground in the residential HVAC market. Priced competitively and carrying the Goodman nameplate, this 18,000 BTU unit targets contractors and homeowners seeking straightforward replacement without premium costs. Its 14-inch horizontal configuration and A-coil style fit standard attic and basement placements, making it a familiar option for most retrofit installations. The unit uses R454B refrigerant, reflecting current industry compliance standards.

Performance metrics show a solid 13 SEER1 efficiency rating, which meets minimum modern standards but trails higher-tier options offering 14-16 SEER. The single-stage rotary compressor runs at 74 dB, moderately loud for residential settings. Electrical requirements stay modest at 208/230 V single-phase with a 9.1 to 15-amp breaker range, simplifying integration into existing homes. The 3/8-inch liquid line and 3/4-inch suction line with matching valve sizes ensure straightforward connection to most outdoor condensers.

Pros & Cons

Pros

  • 13 SEER efficiency meets baseline modern standards with 18,000 BTU cooling capacity at 1.5 tons
  • R454B refrigerant aligns with current EPA phase-down regulations, future-proofing your system
  • Horizontal 14-inch A-coil design fits standard residential attic and basement installations
  • Single-stage rotary compressor offers reliable performance with fewer mechanical complexities
  • 10-year warranty with online registration provides solid consumer protection

Cons

  • 13 SEER rating falls below mid-tier competitors offering 14-16 SEER at similar price points
  • 74 dB noise level at single-stage operation makes it louder than variable-capacity alternatives
  • Not ENERGY STAR certified, missing potential tax credits and rebate eligibility

Who Should Buy

Best For

This coil suits contractors performing straightforward residential replacements on tight budgets and homeowners in temperate climates without extreme cooling demands. It's especially attractive for rental properties or situations where upfront cost matters more than long-term energy savings.

Consider Alternatives If

Skip this if you need ENERGY STAR certification for rebates, live in hot climates requiring maximum efficiency, or prioritize quiet operation, as the 74 dB output and single-stage design won't satisfy those requirements.

Installation

Installation complexity remains low thanks to standard sweat valve connections and common line sizes. The 120-pound weight requires two technicians for safe handling, but the 14-inch height and 21.125-inch width navigate typical attic and closet spaces without issues. Pre-insulated 3/4-inch suction lines reduce field work. Most contractors complete installation in one to two hours on standard replacements.

Warranty & Reliability

Goodman's 10-year parts warranty activates upon online registration, covering compressor and refrigerant lines. This exceeds many budget-tier competitors but trails premium brands offering 12-15 years. Registration is essential, as unregistered units carry shorter coverage. Labor costs remain the buyer's responsibility.

Frequently Asked Questions

Does this coil work with my existing Goodman condenser unit? +
Yes, if your condenser is 1.5 ton or 2 ton rated and uses 3/8-inch liquid and 3/4-inch suction lines with sweat connections. Verify refrigerant compatibility, as older units using R22 require professional conversion or replacement. This coil ships with 50 feet of pre-insulated suction line.
Will this fit my attic space measuring 48 inches wide and 18 inches tall? +
No. The coil measures 21.125 inches wide and 14 inches tall, requiring a minimum 22-inch-wide opening. Your space is too narrow. Consider the vertical A-coil alternative or relocate to a basement if available.
How does 13 SEER compare to newer high-efficiency units? +
13 SEER is about 15-20% less efficient than 15-16 SEER systems. Over 15 years, expect approximately $200-400 higher energy costs in moderate climates, rising to $600+ in hot regions. The trade-off is lower upfront expense.
Is R454B refrigerant harder to service than R22 or R410A? +
R454B requires the same certified technician and similar tools as R410A. Supply availability is improving as adoption increases industry-wide. Expect slightly higher costs than R410A during the transition period.
What happens if I don't register the warranty online? +
Warranty coverage drops significantly without registration. Always complete registration within 30 days of installation to secure the full 10-year term. Keep proof of purchase and registration documentation.
