Review
The ACiQ 4-ton horizontal gas furnace and air conditioning system occupies a practical middle ground in the residential HVAC market. This Goodman-branded unit delivers solid efficiency ratings and flexible installation options without the premium pricing of ultra-high-efficiency models. It's designed specifically for contractors working in space-constrained applications where traditional vertical configurations aren't viable, making it a go-to spec for basement retrofits, crawlspace installations, and tight attic applications.
Performance numbers tell a straightforward story. The furnace achieves 96% AFUE, meaning 96 cents of every heating dollar converts to usable heat, with a 120,000 BTU output. The cooling side delivers 48,000 BTU at 14 SEER efficiency using R454B refrigerant. The scroll compressor operates in single-stage mode, while the two-stage gas burner provides better part-load efficiency than single-stage alternatives. The multi-speed ECM blower motor maxes out at 2,000 CFM, adjusting automatically to match system demand.
Pros & Cons
Pros
- 96% AFUE furnace rating burns less fuel and cuts heating costs meaningfully
- 14 SEER cooling efficiency qualifies for many state rebates, offsetting equipment cost
- Horizontal configuration fits tight spaces where traditional upflow units won't work
- Multi-speed ECM blower motor adjusts fan speed to match heating and cooling demand
- Two-stage burner reduces short-cycling and improves comfort during mild weather
- Plastic PVC exhaust flue simplifies venting compared to metal ductwork
Cons
- Not Energy Star certified, which disqualifies some utility rebate programs
- Single-stage condenser compressor is less efficient than two-stage alternatives
- 74 dB noise level is moderately loud for basement installations near living spaces
- R454B refrigerant requires specialized handling and EPA-certified technicians
Who Should Buy
Best For
Contractors renovating homes with tight mechanical spaces, crawlspaces, or attics will appreciate the horizontal design flexibility. Budget-conscious homeowners in moderate climates wanting solid efficiency without premium pricing will find the 96% AFUE and 14 SEER balance cost and performance well.
Consider Alternatives If
Homeowners in extremely cold climates should consider modulating furnaces with higher staging, and those seeking top-tier efficiency should look at 16 SEER or higher systems with variable-speed compressors.
Installation
Horizontal installation is straightforward for certified technicians familiar with A-coil configurations. The unit measures 24.5 inches tall, 26 inches wide, and 21.125 inches deep, fitting tight spaces effectively. Plastic PVC exhaust venting simplifies flue installation compared to metal alternatives. Electrical requirements are 208 to 230 volt single-phase 60 Hz, with breaker sizing between 26.4 and 45 amps. Pre-charged refrigerant lines come in 30-foot lengths with 3/8-inch suction and liquid connections.
Warranty & Reliability
ACiQ backs this system with a 10-year parts warranty when registered online. Registration is free and typically takes five minutes through the manufacturer's website. This warranty covers compressor, blower motor, and heat exchanger defects. Labor coverage varies by installer, so confirm service plan details before purchase. The 10-year term is competitive for mid-range equipment, though premium brands sometimes offer longer periods.
