Review
The ACiQ 4-ton system, branded under Goodman, represents a middle-ground approach to residential heating and cooling. At $0, it positions itself as an accessible option for contractors and homeowners seeking respectable efficiency without flagship pricing. This upflow configuration suits most residential installations, and the plastic PVC exhaust compatibility removes a major installation barrier that plagues older homes with masonry vents.
The furnace delivers 120,000 BTU of heating with an exceptional 97% AFUE rating, meaning 97 cents of every fuel dollar converts to usable heat. The modulating burner is the real efficiency hero here, continuously adjusting output rather than cycling on-off like single-stage units. The variable-speed ECM blower pulls 2,000 CFM maximum while adapting to heating and cooling needs, improving comfort and reducing energy waste compared to fixed-speed alternatives.
Pros & Cons
Pros
- 97% AFUE furnace efficiency significantly reduces heating costs compared to 80-90% models
- Modulating burner automatically adjusts heat output between 30-100%, eliminating temperature swings
- Variable-speed ECM blower delivers 2,000 CFM maximum with better air distribution and quieter operation
- PVC exhaust compatible, eliminating expensive masonry vent upgrades on many homes
- R454B refrigerant meets current EPA environmental standards for cooling performance
- 10-year warranty with online registration provides solid protection on both heating and cooling sides
Cons
- Not ENERGY STAR certified, missing potential rebate opportunities available for qualifying systems
- Single-stage condenser limits cooling efficiency in extreme heat, SEER1 of 13 is competent but not premium
- 76 dB noise level slightly above whisper-quiet standards, noticeable in quiet living spaces
Who Should Buy
Best For
Contractors upgrading older furnaces where PVC venting is available, and homeowners in gas-heated homes wanting to maximize heating efficiency without premium-tier pricing. This system works especially well in climates with extended heating seasons where the 97% AFUE delivers measurable annual savings.
Consider Alternatives If
Buyers seeking ENERGY STAR certification for rebate eligibility or homeowners in hot climates prioritizing cooling performance over heating efficiency should explore alternatives.
Installation
Installation requires 208/230V single-phase 60Hz power with breaker sizing between 26.3 and 45 amps. Technicians need to run suction line insulation rated at 1/2 inch thickness up to 50 feet for the refrigerant connections. PVC venting simplifies ductwork compared to rigid metal, though proper slope and condensation traps remain critical for reliability.
Warranty & Reliability
The 10-year parts and labor warranty activates upon online registration, covering both the furnace and air conditioning components. This is respectable coverage in the mid-tier market. Registration is straightforward and essential, as unregistered units typically receive only five years coverage.
