// Bottom Line
This ACiQ unit excels as a replacement for older Goodman systems, delivering 96% AFUE heating efficiency and 13 SEER cooling in a compact downflow configuration. It's particularly valuable for contractors doing equipment swaps where space constraints and modern refrigerant compatibility matter.

Review

ACiQ's 2-ton combination system pairs an 80,000 BTU gas furnace with a 24,000 BTU air conditioning condenser in a downflow configuration designed for space-constrained installations. This unit replaces the Goodman GSX130242, inheriting proven manufacturing while upgrading to modern R454B refrigerant. The compact 21x21x30 inch dimensions and variable-speed ECM blower make it attractive for retrofit applications where contractors need efficiency gains without complete ductwork reconfiguration.

The furnace delivers impressive 96% AFUE efficiency through two-stage burner technology that adjusts heating output based on demand, reducing fuel consumption and improving comfort consistency. On the cooling side, 13 SEER1 performance is respectable but not class-leading, with a single-stage rotary compressor limiting modulation capability. The variable-speed blower maxes out at 1,600 CFM and operates at 75 dB, audible during peak cycles but quieter than single-speed alternatives. Electrical requirements remain modest at 10.3 to 15 amps on 208/230V single-phase power.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency reduces heating costs significantly compared to older units operating at 78-80%
  • Variable-speed ECM blower motor provides better temperature control and quieter operation than single-speed alternatives
  • R454B refrigerant future-proofs the system against regulatory phase-outs affecting older R410A equipment
  • Two-stage burner allows modulated heating for improved comfort and reduced energy waste
  • Compact 21x21x30 inch footprint fits tight installations where standard units won't work
  • PVC exhaust flue option simplifies venting compared to metal ductwork requirements

Cons

  • 13 SEER1 is solid but not exceptional, trailing newer 16+ SEER systems by meaningful margins
  • 75 dB noise level runs louder than premium variable-speed systems, noticeable during operation
  • Single-stage condenser cannot modulate cooling capacity, reducing efficiency during mild weather
  • Price listed at $0 suggests incomplete data, making cost comparison impossible
  • Not ENERGY STAR certified despite high AFUE rating, limiting incentive program eligibility

Who Should Buy

Best For

Contractors replacing failed Goodman GSX130242 units will find this a direct substitute that modernizes efficiency without complete system redesign. Homeowners in homes with limited mechanical space, particularly those with downflow or horizontal installations, gain the benefits of 96% efficiency in a unit that actually fits their existing footprint.

Consider Alternatives If

Buyers prioritizing lowest cooling costs should compare 16+ SEER systems instead, as 13 SEER represents older efficiency tiers despite the furnace side being excellent.

Installation

Downflow installation requires proper ductwork configuration below the unit, making crawlspace or basement applications ideal. PVC exhaust flue simplifies venting compared to metal alternatives, though local codes vary. The 3/8 inch liquid line and 3/4 inch suction line with 3/4 inch insulation are standard sizes; the 50-foot pre-insulated line accommodates most residential split systems. Technicians familiar with R454B refrigerant charging should find setup straightforward with AHRI Certificate 7368843 ensuring proper system matching.

Warranty & Reliability

ACiQ provides 10-year warranty coverage with online registration required to activate protection. This covers manufacturing defects and component failures, providing meaningful peace of mind beyond the industry standard 5-year baseline. Registration is straightforward but essential, as coverage lapses without completion. The Goodman evaporator coil carries separate warranty documentation included in the resource package.

Frequently Asked Questions

How does 96% AFUE compare to my current furnace efficiency? +
If your furnace is 10+ years old, it likely operates at 78-82% AFUE. The 96% rating means roughly 18-20% more heat output per dollar of natural gas or propane, translating to $300-600 annual savings for typical homes. Two-stage burners enhance this by avoiding full-capacity operation during mild weather.
Can this unit replace a standard upflow furnace installation? +
Yes, the ACIQ-24-EHPD-UPG is configurable for both upflow and downflow, though this listing specifies downflow. Verify your ductwork can accommodate the airflow direction before installation. Contact the manufacturer if your existing system requires upflow configuration to confirm compatibility.
Is 13 SEER cooling efficiency good enough for Texas or Arizona climates? +
13 SEER is adequate but not optimal for hot climates where AC runs heavily. You'll see meaningful cooling cost increases compared to 16+ SEER systems. If cooling dominates your energy bills, investing in a higher SEER condenser pays dividends in hot regions despite higher upfront cost.
How does R454B refrigerant differ from the R410A in older Goodman units? +
R454B has slightly lower global warming potential and aligns with EPA's future refrigerant roadmap, protecting you from phase-outs hitting R410A equipment after 2025. It's not directly interchangeable, meaning new units use new refrigerant entirely. This future-proofs your investment against regulatory restrictions.
What happens if I don't register the warranty online? +
Without online registration, the 10-year warranty does not activate and you lose coverage. Registration is free and takes minutes through ACiQ's website. Keep your AHRI certificate number (7368843) and purchase documentation for the process.
