Review
The ACiQ 3.5 ton gas furnace and air conditioner system represents a practical middle ground in the HVAC market. Built on Goodman's established platform, this upflow unit combines solid efficiency ratings with straightforward installation, making it attractive to contractors managing tight project timelines. The 96% AFUE furnace and 14 SEER condenser deliver above-average performance without the premium pricing of high-end variable-capacity systems.
Heating performance reaches 100,000 BTU output with two-stage burner modulation, while cooling delivers 42,000 BTU through a single-stage scroll compressor. The variable-speed ECM blower motor runs up to 2000 CFM and adjusts output based on demand, improving both efficiency and quiet operation. At 73 dB, the outdoor unit produces typical noise for single-stage condensers. The system operates on 115V single-phase power with a recommended 22 to 35 amp breaker, making it compatible with standard residential electrical service.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% models
- 14 SEER cooling efficiency exceeds ENERGY STAR requirements and qualifies for rebates
- Variable-speed ECM blower motor optimizes comfort and reduces energy waste at part load
- Two-stage gas burner provides modulated heat output for quieter, more efficient operation
- PVC exhaust flue compatibility simplifies installation in older homes and retrofit applications
Cons
- Single-stage air conditioner compressor cannot modulate capacity, resulting in less precise temperature control than two-stage units
- 73 dB noise level is moderately loud for residential outdoor condenser operation
- Spec sheet lists conflicting tonnage information (3.5 tons in title but 5 tons in specs, creating confusion about actual system capacity)
Who Should Buy
Best For
Contractors installing replacement systems in homes with natural gas or propane service, and homeowners in cooler climates where heating efficiency is the priority. This system works well for upflow applications in basements or utility closets where PVC venting is feasible.
Consider Alternatives If
Homeowners seeking variable-capacity cooling or those in hot climates where AC runtime dominates should consider two-stage compressor models for better efficiency and comfort.
Installation
The upflow A-coil configuration suits basement and closet installations. PVC exhaust flue requirements simplify venting compared to metal ductwork alternatives. Liquid and suction lines measure 3/8 inch and 7/8 inch respectively, with 3/8 inch insulation thickness on the suction line. Installation requires proper refrigerant charging and ECM blower configuration. Most experienced HVAC contractors can complete the job within standard timeframes.
Warranty & Reliability
Coverage extends 10 years with online registration, providing solid peace of mind for defects in parts and workmanship. This aligns with industry standards for mid-tier equipment. Registration is straightforward but required to activate the full coverage, so homeowners should complete this immediately after installation to protect their investment.
