1.5 Ton 13 SEER Goodman Air Conditioner with Vertical 17.5" Cased Coil Review 2026

// Bottom Line

This ACiQ coil excels for contractors building replacement systems on tight budgets or homeowners retrofitting older units with modern refrigerant. The 13 SEER rating meets current minimum standards, and the compact 17.5" width fits most existing cabinets without modification.

Review

The ACiQ 1.5 ton air conditioner coil with vertical 17.5" casing fills a specific market gap, serving contractors and homeowners who need a straightforward replacement coil without premium pricing. This unit handles 18,000 BTU cooling capacity using R454B refrigerant, the modern low-GWP standard replacing older R410A systems. The combination of compact dimensions, established manufacturer backing, and accessible price point makes it a practical choice for standard residential retrofit applications.

Performance specs show a 13 SEER efficiency rating, which meets current federal minimum requirements but sits at the entry level of the market. The single-stage rotary compressor operates at 74 dB, noticeably louder than variable-capacity alternatives. Electrical requirements are modest at 208/230V single phase with a 9.1 to 15 amp breaker range, simplifying panel compatibility. The unit weighs 120 pounds and incorporates 3/8 inch liquid line and 3/4 inch suction line connections with sweat valve configuration.

Pros & Cons

Pros

13 SEER efficiency meets minimum federal standards at entry-level pricing
R454B refrigerant future-proofs against EPA phase-down of older refrigerants
Compact 17.5" width and 18" height fit standard replacement applications without custom ductwork
10-year warranty with online registration provides legitimate peace of mind
Single-stage rotary compressor design simplifies installation and service calls

Cons

13 SEER is baseline efficiency, not competitive with 14+ SEER mid-tier options
74 dB noise level runs louder than variable-speed premium units
Not Energy Star certified, limiting appeal to efficiency-conscious buyers

Who Should Buy

Best For

Budget-conscious homeowners replacing failed air conditioning systems and contractors managing tight project margins. This coil works particularly well in replacement applications where preserving existing ductwork and cabinet dimensions is critical.

Consider Alternatives If

Anyone prioritizing quiet operation or maximum energy savings should explore 14+ SEER units, as the noise level and efficiency gap justify the upgrade cost over a 10+ year lifespan.

Installation

Installation uses standard sweat connections with 3/8 inch liquid line and 3/4 inch suction line sizing. The 17.5 inch width and 18 inch height fit most existing indoor cabinet spaces without modification. Technicians appreciate the straightforward single-stage design, which requires no additional controls or staging equipment. Pre-insulated suction line tubing (3/4 inch thickness, 50 feet supplied) reduces jobsite prep time and minimizes installation error.

Warranty & Reliability

ACiQ backs this coil with a 10-year warranty upon online registration, covering manufacturing defects and workmanship. This registration requirement is standard in the industry and typically takes minutes to complete. The warranty is non-transferable and requires proper installation per CAPF specifications, so documentation of the installation is recommended for future claims.

Frequently Asked Questions

Is this coil compatible with my existing outdoor condenser unit? +

Compatibility depends on your current system's refrigerant, tonnage, and connection sizing. The R454B refrigerant and 1.5 ton capacity must match your condenser specifications. Verify liquid and suction line diameters (3/8 inch and 3/4 inch respectively) with your outdoor unit documentation before ordering.

Can I install this myself, or do I need a licensed technician? +

EPA regulations require certified technicians to handle refrigerant systems in all U.S. states. Professional installation is mandatory, not optional. Proper evacuation, brazing, and refrigerant charge procedures demand specialized equipment and training that unlicensed installers cannot legally perform.

How does 13 SEER compare to other coils in this price range? +

13 SEER is the federal minimum standard as of 2023. Most competitors at this price point also hit 13 SEER. You'll find 14-15 SEER options available, but expect $200 to $400 higher pricing. The payback depends on your local electricity rates and cooling hours annually.

Why is this unit louder than premium models at 74 dB? +

Single-stage compressors run continuously at full capacity, creating steady noise output. Variable-capacity units modulate speed and produce less overall sound. At 74 dB, expect noise similar to a dishwasher or lawn mower from several feet away during operation.

What does the 10-year warranty actually cover? +

Defects in materials and workmanship are covered. Normal wear, improper installation, refrigerant loss, and system modifications are excluded. Registration is required within 30 days of purchase to activate coverage.
