// Bottom Line
This ACiQ 3 ton coil is ideal for contractors replacing failed Goodman evaporators on existing installations where system capacity and efficiency matter equally. It's a straightforward swap for GSX130362/363/365 units, delivering proven 13 SEER performance without overengineering or premium pricing.

Review

The ACiQ 3 ton horizontal cased coil fills a critical niche in the replacement market. Positioned as a mid-tier option between economy and premium evaporators, it targets contractors and homeowners maintaining existing Goodman systems. At 36,000 BTU cooling capacity with 13 SEER1 efficiency, this unit delivers consistent performance without unnecessary complexity. The horizontal A-coil design works within standard residential ductwork, and the direct compatibility with three Goodman models reduces installation surprises.

Performance specs show a balanced design. The 36,000 BTU rating matches the 3.5 ton designation, while 13 SEER1 indicates moderate efficiency appropriate for moderate climates. The reciprocating compressor operates at 74 dBA, which is audible but typical for this category. Refrigerant is R454B, meeting current EPA standards. Electrical requirements are straightforward: 208/230V single phase with breaker sizing between 19.1 and 30 amps covers most standard residential panels without upgrades.

Pros & Cons

Pros

  • Direct replacement for three common Goodman models (GSX130362, GSX130363, GSX130365) minimizes compatibility headaches
  • 13 SEER1 efficiency rating balances performance and operating costs for mixed-climate applications
  • R454B refrigerant aligns with modern EPA standards and future regulations
  • Horizontal A-coil configuration fits standard attic and basement installations without major modifications
  • 10-year warranty with online registration provides solid long-term protection

Cons

  • 74 dBA noise level is moderate to high, noticeable in quiet residential settings during operation
  • Single-stage reciprocating compressor lacks variable capacity efficiency advantages of two-stage or scroll designs
  • Not Energy Star certified, meaning it meets baseline standards but not premium efficiency tiers
  • Requires 208/230V single-phase power with 19.1 to 30 amp breaker capacity, limiting some older home installations

Who Should Buy

Best For

Contractors managing Goodman system replacements and homeowners with functioning condenser units needing coil repair will appreciate the direct fit and proven track record. This is especially relevant in moderate climates where 13 SEER delivers adequate efficiency without premium costs.

Consider Alternatives If

Homeowners prioritizing whisper-quiet operation or maximum seasonal efficiency should explore higher SEER options, and those building new systems with non-Goodman equipment will find better-matched alternatives.

Installation

Installation is contractor-friendly. The sweat valve connections use standard 3/8 inch liquid and 7/8 inch suction lines, both fitting common system configurations. The 21 inch height and 26 inch depth fit horizontal attic/basement installations without excessive modifications. Pre-insulated suction line (3/8 inch thickness) reduces field insulation work. Allow 30 feet of line set for typical residential runs, and plan for basic brazing and evacuation procedures.

Warranty & Reliability

Coverage runs 10 years from purchase when you complete online registration, a common requirement among modern manufacturers. This protects against manufacturing defects and component failure but typically excludes wear items and improper installation. The registration is straightforward and unlocks the full benefit, making it a practical step for buyers investing in this unit's long-term reliability.

Frequently Asked Questions

Will this coil work with my existing Goodman condenser unit? +
Yes, if your condenser is a GSX130362, GSX130363, or GSX130365 model. This ACiQ coil is a direct bolt-in replacement for those units. If you have a different Goodman model, verify compatibility before ordering. The sweat connections and line sizes match standard Goodman configurations.
What electrical upgrades might I need? +
Most homes with standard 200-amp service panels can handle this unit. It requires 208/230V single-phase power with a 19.1 to 30 amp breaker. If your current system uses a smaller breaker, you'll need an upgrade. Have a licensed electrician verify your panel capacity before installation.
How efficient is 13 SEER1 compared to newer air conditioners? +
13 SEER1 is solid mid-range efficiency. Newer systems range from 14 to 18+ SEER2. This unit costs less but will have slightly higher operating costs in hot climates. It's ideal for moderate climates or when budgets limit the efficiency investment. Calculate your payback period based on local electricity rates.
Can I pair this with a non-Goodman condenser? +
Not recommended without expert verification. This coil is engineered for Goodman systems. Mismatched condenser and coil can reduce efficiency, void warranties, and create reliability problems. Always pair replacement coils with compatible manufacturers.
Does the 10-year warranty cover everything? +
The warranty covers manufacturing defects and component failures, not installation errors or neglect. Online registration is required to activate it. Normal wear items and refrigerant loss from leaks typically aren't covered. Review full terms with your installer before purchase.
