Review
The ACiQ 3.5-ton upflow system represents a straightforward approach to split-system HVAC: solid core components at an entry-level price. At $647, this unit targets cost-conscious contractors and homeowners without sacrificing the efficiency metrics that matter for operating costs. The upflow A-coil configuration fits standard attic installations, and the compact footprint, measuring 34.5 inches tall by 21 inches wide by 28.75 inches deep, accommodates most residential spaces. ACiQ positions itself as Goodman's value-oriented brand, and this pricing reflects that positioning.
Performance specs confirm genuine capability. The cooling side delivers 36,000 BTU at 14 SEER1 efficiency, outpacing base-model competitors and delivering roughly 15-20% better efficiency than 11-12 SEER systems from a decade ago. The heating side generates 80,000 BTU with 97% AFUE, a high rating that means minimal heat loss through the flue. The modulating burner automatically adjusts between stages rather than simple on-off cycling, reducing temperature swings. The variable-speed ECM blower motor spins slower during part-load conditions, consuming less electricity than fixed-speed alternatives.
Pros & Cons
Pros
- 14 SEER rating exceeds ENERGY STAR minimums and delivers measurable energy savings on cooling costs
- 97% AFUE furnace efficiency is genuinely high for a modulating gas burner system at this price tier
- Variable-speed ECM blower motor adapts to demand, reducing runtime and electricity consumption versus single-speed alternatives
- Modulating burner with two-stage heating prevents overshooting temperature setpoints and improves comfort stability
- R454B refrigerant is newer, lower-GWP formulation with better environmental credentials than older R410A systems
Cons
- Single-stage compressor means cooling capacity is fixed, not variable like higher-end models
- 73 dB noise level is audible from inside during compressor operation, especially on hot days
- Warranty requires online registration to qualify for the full 10-year term, creating an extra administrative step
Who Should Buy
Best For
Contractors and homeowners in moderate climates who value efficiency without premium pricing, and who can handle basic online warranty registration. This unit works well in homes with consistent cooling demand where a fixed compressor won't cycle excessively.
Consider Alternatives If
Buyers in extreme hot climates needing variable-capacity cooling, or anyone unwilling to register warranty online and instead preferring automatic coverage.
Installation
This upflow unit requires a standard split-system installation with refrigerant line runs up to 30 feet. Liquid line is 3/8 inch with matching valve, suction line is 3/4 inch, both insulated with 3/4-inch foam. The furnace accepts natural gas or propane with plastic PVC exhaust flue. Electrical demand maxes at 30 amps on a single 115V, 60 Hz circuit. Installation complexity is moderate, well within the scope of HVAC technicians familiar with residential split systems.
Warranty & Reliability
The system includes a 10-year warranty on all components, contingent on completing online registration immediately after purchase. This non-transferable coverage protects against manufacturing defects but does not cover refrigerant, routine maintenance, or damage from installer error. The registration requirement is typical for mid-tier equipment and ensures manufacturer contact information is current for warranty claims.
