Review
The ACiQ 4-ton unit (branded as Goodman in some markets) sits squarely in the reliable mid-tier segment. It combines a 46,000 BTU AC condenser with a 120,000 BTU gas furnace, delivering 14 SEER1 cooling and 80% AFUE heating efficiency. Energy Star certification qualifies buyers for utility rebates, offsetting some upfront costs. The A-coil configuration supports both upflow and horizontal mounting, making it adaptable to attic or basement installations across different home layouts.
Performance specs show a 5-ton capacity rated system with scroll compressor single-stage cooling that cycles on and off rather than modulating. The 2,000 CFM maximum airflow supports adequate dehumidification in moderate climates, though humidity control won't match variable-capacity units. At 120V single-phase 60Hz, electrical requirements are straightforward, needing 26.4 to 40 amp breakers. R454B refrigerant and sweat-type valve connections streamline installation work compared to newer proprietary fittings on premium models.
Pros & Cons
Pros
- 14 SEER1 cooling efficiency exceeds minimum standards and qualifies for Energy Star rebates
- 80% AFUE furnace provides solid heating efficiency for gas systems without modulation
- 46,000 BTU cooling capacity handles humid climates reasonably well despite single-stage compressor
- R454B refrigerant is drop-in compatible with existing R410A linesets, simplifying retrofit installations
- 10-year parts warranty with online registration offers peace of mind without dealer registration fees
Cons
- Single-stage compressor cycling creates wider temperature swings compared to variable-speed models
- 74 dB noise level at outdoor unit is audible during operation, particularly noticeable in quiet neighborhoods
- 80% AFUE furnace leaves efficiency gains on the table versus 92%+ high-efficiency units available today
Who Should Buy
Best For
Homeowners replacing 10+ year old systems who want balanced efficiency and cost, or contractors building mid-range packages for budget-conscious customers. This works well in regions without extreme heating demands where single-stage operation isn't a significant drawback.
Consider Alternatives If
Skip this if you need whisper-quiet operation, live in a cold climate requiring efficient heating, or qualify for utility rebates that require 16 SEER or higher systems.
Installation
Installation requires standard EPA certifications and line-set sizing for R454B. The upflow/horizontal configuration allows placement in attics, basements, or utility closets without major ductwork modifications. Metal exhaust flue requirement is typical for gas furnaces. Suction line insulation at 0.5 inches thickness and 3/8-inch liquid line sizing follow industry standards. Most experienced HVAC contractors complete installation in 4-6 hours without complications.
Warranty & Reliability
Ten-year parts warranty covers defects in materials and workmanship when registered online within 30 days of purchase. This applies to both the AC condenser and furnace components. Labor and refrigerant are not covered, so service calls beyond warranty period may cost $150-300 depending on local rates. Registration is free and takes minutes online through ACiQ's portal.
