Review
The ACiQ 3-ton combo system represents the practical middle ground of residential HVAC, delivering solid performance without the premium price of high-efficiency units. With a 96% AFUE furnace and 13 SEER air conditioner paired in one upflow A-coil configuration, this system handles both seasonal extremes in moderate climates. It replaces three older Goodman models (GSX130362, GSX130363, GSX130365), making it a legitimate upgrade path for existing Goodman customers. Energy Star certification confirms the unit meets strict efficiency standards without overpromising performance.
Performance metrics are straightforward and honest. The furnace delivers 100,000 BTU heating output with two burner stages, hitting 96% efficiency on the AFUE scale. The air conditioner produces 36,000 BTU cooling capacity at 13 SEER1 efficiency using R454B refrigerant. The variable-speed ECM blower adjusts airflow up to 2,000 CFM, allowing the system to ramp up or down based on demand rather than running flat-out constantly. At 74 dB, the outdoor unit is moderately loud but not unusual for this tonnage class. Electrical requirements are reasonable: 115V single-phase, pulling between 19.1 and 30 amps maximum.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means lower heating bills, particularly valuable in colder months
- 13 SEER cooling efficiency with Energy Star certification provides reliable summer performance
- Two-stage burner and variable-speed ECM blower allow the system to modulate output, reducing cycling and improving comfort
- Lifetime heat exchanger warranty protects your biggest investment, backed by 10 years on parts with online registration
- PVC/plastic exhaust flue compatibility simplifies installation in many homes compared to metal vent requirements
- R454B refrigerant is newer, more efficient formula with lower environmental impact than older refrigerants
Cons
- Single-stage compressor means the AC cannot modulate cooling capacity, resulting in less precise temperature control than two-stage units
- 3.5-ton capacity creates a slight mismatch if your home actually requires 3-ton cooling, potentially causing minor oversizing
- 74 dB noise level is moderate to loud, noticeable during operation especially in quiet neighborhoods
Who Should Buy
Best For
Homeowners with existing Goodman equipment replacing units of similar capacity, or those in mixed heating/cooling climates where a mid-tier efficiency system fits budget constraints. This is also solid for contractors who service Goodman systems regularly and need field-proven replacement components.
Consider Alternatives If
Skip this if you live in a cooling-dominant climate where two-stage compressor cooling would deliver noticeably better comfort, or if your home requires genuine 3-ton capacity and you want to avoid even slight oversizing.
Installation
This upflow configuration fits standard attic or basement installations with straightforward ductwork. Valve sizes are standard, 3/8-inch liquid line and 3/4-inch suction line, allowing use of existing copper runs in many replacement scenarios. The A-coil design pairs easily with most furnace cabinets. Dimensions (34.5-inch height, 21-inch width, 28.75-inch depth) fit typical equipment closets. PVC exhaust venting simplifies installation compared to rigid metal pipes, reducing labor time and cost.
Warranty & Reliability
The lifetime heat exchanger warranty is the standout coverage, protecting against the most expensive potential failure. Ten-year parts warranty applies when you register online, though this requires proof of professional installation. Heat exchanger coverage alone justifies the registration step, as replacement costs typically exceed $1,500. Parts coverage beyond the heat exchanger lasts a decade, standard for this price tier.
