// Bottom Line
This combination system works best for homeowners in cold climates where heating dominates energy costs and who want efficient propane or natural gas backup. The 97% AFUE rating and modulating burner mean you'll recover the efficiency investment faster in heating-heavy regions.

Review

The ACiQ 2 ton system, model ACIQ-24-EHPD-UPG, pairs a Goodman gas furnace with an air conditioner condenser in a horizontal downflow configuration. This is a replacement for the older GSX130242 unit and targets homeowners who heat with propane or natural gas while needing basic cooling. The combination approach simplifies installation compared to sourcing separate furnace and condenser units from different manufacturers.

Efficiency is the real selling point here. The furnace delivers 97% AFUE with modulating burner stages that adjust heat output continuously instead of cycling on and off, reducing energy waste during partial load operation. The 80,000 BTU heating capacity handles 2 ton cooling duty, paired with a 24,000 BTU air conditioner rated at 13 SEER1. The variable speed ECM blower adjusts to 1200 CFM maximum, meaning it ramps down on mild days and runs only as hard as needed.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency is among the highest available for gas furnaces, reducing heating fuel consumption significantly
  • Modulating burner stages adjust heat output precisely, avoiding the energy waste of constant on-off cycling
  • Variable speed ECM blower matches airflow to demand, improving comfort and lowering fan energy use
  • 13 SEER1 air conditioning with R454B refrigerant meets current environmental standards and Energy Star certification
  • PVC exhaust compatibility simplifies venting in retrofit situations where traditional metal flues aren't practical
  • 10 year warranty with online registration provides solid protection for parts and manufacturing defects

Cons

  • 3 ton cooling capacity on what's labeled as a 2 ton system creates spec confusion and potential oversizing for smaller homes
  • Single stage condenser limits cooling efficiency at partial load conditions compared to two stage units
  • 75 dB noise level is louder than high efficiency two stage outdoor units, noticeable during operation
  • Requires proper refrigerant line sizing, 3/8 inch liquid and 3/4 inch suction with 3/4 inch insulation thickness

Who Should Buy

Best For

Contractors and homeowners in northern climates where winter heating accounts for 60 percent or more of annual HVAC energy use will see real ROI from the 97% AFUE rating. This system also suits properties using propane in areas where natural gas lines aren't available.

Consider Alternatives If

Cooling-dominant markets in the South and Southwest should look at units with two stage compressors or higher SEER ratings for better part load efficiency, since this single stage design won't match their usage patterns.

Installation

Installation requires standard HVAC copper line work with 3/8 inch liquid and 3/4 inch suction lines, both insulated to 3/4 inch thickness. The horizontal A-coil configuration fits attic or basement installations where downflow discharge is acceptable. PVC venting to the exterior simplifies flue routing in tight spaces. Electrical demand is minimal at 115V single phase 60 Hz, requiring a 10.3 to 15 amp breaker.

Warranty & Reliability

ACiQ provides a 10 year parts and labor warranty when you register online after purchase. This is a solid mid-tier protection that covers manufacturing defects and component failures during the critical first decade. Registration is simple and typically extends coverage that Goodman's base warranty might otherwise limit to 5 years.

Frequently Asked Questions

Why does the spec sheet say 2 ton but the tonnage field shows 3 ton? +
The system is marketed as a 2 ton matched pair for heating purposes, but the air conditioner condenser is rated at 24,000 BTU, which technically qualifies as 2 ton cooling. The 3 ton tonnage reference likely refers to total system capacity. Always verify cooling and heating BTU separately rather than relying on tonnage alone.
Can this unit replace an old 2 ton Goodman system, and what about the refrigerant change to R454B? +
Yes, it replaces model GSX130242 directly. However, R454B is a newer fourth generation refrigerant incompatible with R410A systems. You'll need a complete system change with new lines and evacuation. Don't attempt retrofit charging with mixed refrigerants.
How much will the 97% AFUE furnace reduce my heating bill compared to an 80% AFUE unit? +
The 17 percentage point difference means 97% efficiency systems waste only 3 cents per dollar of fuel while 80% systems waste 20 cents. On an 80,000 BTU furnace running 1500 hours annually, you'd save approximately $150 to $250 per year in gas costs, depending on local rates.
Is the 13 SEER1 rating competitive for cooling efficiency in 2024? +
13 SEER1 is entry level for modern systems. High efficiency units reach 15 to 18 SEER1 with two stage compressors. This unit will handle cooling adequately but won't minimize summer energy bills. In cooling heavy climates, consider higher SEER options.
What does the 10 year warranty actually cover if something fails? +
The registered warranty covers parts and manufacturing defects for 10 years from installation. Labor coverage varies by dealer. Refrigerant, routine maintenance, and damage from improper installation typically aren't covered.
