Review
The ACiQ 3-ton horizontal system combines a high-efficiency Goodman furnace with a mid-range air conditioner in a configuration built for basement, crawlspace, and attic installations. This A-coil design addresses a specific market segment, contractors replacing Goodman legacy equipment and homeowners balancing comfort upgrades with budget constraints. Energy Star certification and modern refrigerant support current efficiency standards, though the overall package positions itself as a practical middle-ground solution rather than a premium offering.
Heating performance leads the package with a 97% AFUE modulating furnace delivering 100,000 BTU using natural gas or propane, paired with a variable-speed ECM blower capable of 2000 CFM maximum. Cooling arrives through a single-stage reciprocating compressor rated at 36,000 BTU and 13 SEER, Energy Star qualified with R454B refrigerant. The furnace's modulating burner technology adjusts firing rates between minimum and maximum output, reducing cycling losses during mild weather when full capacity isn't needed.
Pros & Cons
Pros
- 97% AFUE rating with modulating burners reduces heating costs significantly versus single-stage alternatives
- Variable-speed ECM blower motor adjusts airflow from 0 to 2000 CFM for comfort and efficiency optimization
- Energy Star certified with R454B refrigerant meets current environmental standards
- 10-year warranty with online registration provides solid protection without registration complexity
- Horizontal/downflow configuration offers flexible installation in basements, crawlspaces, and attics
- 74 dB noise level keeps operation relatively quiet for basement installations
Cons
- 13 SEER rating is mid-range, trailing competitors offering 14-16 SEER models at similar price points
- Single-stage cooling compressor cannot match variable-capacity systems for part-load efficiency
- 119-amp minimum breaker requirement demands circuit planning in older electrical systems
- R454B refrigerant availability remains limited in some rural markets despite improvements
Who Should Buy
Best For
Contractors and homeowners replacing older Goodman GSX130362, GSX130363, or GSX130365 units will find this drop-in compatible. It's also well-suited for budget-conscious buyers in regions where heating dominates cooling demand, where the 97% AFUE furnace efficiency justifies the purchase over cooling-focused alternatives.
Consider Alternatives If
Homeowners in hot climates prioritizing cooling efficiency should explore 15+ SEER variable-capacity systems, and those with tight electrical infrastructure may face breaker upgrade costs.
Installation
Horizontal/downflow orientation requires 3/8 inch liquid line and 7/8 inch suction line with 3/8 inch insulation thickness for a maximum 30-foot run. Standard 115V single-phase 60Hz electrical with 19.1 to 30-amp breaker sizing fits typical residential panels. PVC exhaust flue compatibility simplifies venting compared to masonry chimney conversions. Licensed HVAC technicians should verify existing ductwork sizing and refrigerant line compatibility before retrofitting.
Warranty & Reliability
Ten-year parts coverage activates upon online registration, standard for mid-tier Goodman equipment. This protects against compressor, heat exchanger, and motor failures but excludes labor costs and wear items like filters. Registration takes five minutes online and should be completed immediately after installation to avoid coverage gaps.
