Review
The ACiQ 3.5 ton combination system pairs a Goodman gas furnace with an air conditioning condenser in one compact package. This downflow-configured unit targets contractors and homeowners seeking an integrated solution that handles both seasonal heating and cooling without installing separate pieces. The 80,000 BTU furnace capacity and 42,000 BTU cooling output serve mid-sized homes, while the dual-fuel design supports natural gas or propane depending on your utility infrastructure.
Efficiency is this system's strongest selling point. The furnace achieves 96% AFUE, meaning nearly all input fuel converts to usable heat rather than escaping through the chimney. The air conditioner delivers 13 SEER cooling efficiency, which qualifies for Energy Star designation and unlocks utility company rebates in most regions. The variable-speed ECM blower motor adjusts fan speed to match heating or cooling demand, reducing unnecessary energy consumption during partial-load operation.
Pros & Cons
Pros
- 96% AFUE furnace rating is best-in-class for natural gas and propane heating efficiency
- 13 SEER cooling efficiency qualifies for Energy Star certification and utility rebates
- Two-stage burner and variable-speed ECM blower motor optimize comfort and reduce runtime costs
- Compact footprint of 30 inches by 21 inches by 21 inches fits tight mechanical spaces
- Plastic PVC exhaust flue reduces installation complexity and material costs versus metal venting
Cons
- Single-stage condenser limits part-load efficiency during mild weather compared to two-stage units
- 75 dB noise level is moderately loud, noticeable in quiet residential settings
- 3.5 ton cooling capacity may undersiz larger homes or humid climates despite 5 ton furnace rating
Who Should Buy
Best For
This system suits homeowners in temperate to cold climates where heating demand justifies the high AFUE rating. It works well for retrofits into existing downflow or horizontal installations where duct configuration is already set.
Consider Alternatives If
Skip this unit if you live in hot climates where cooling dominates, as the single-stage compressor wastes energy in part-load conditions, or if noise concerns matter in your home.
Installation
Installation requires standard HVAC skills and tools. The reciprocating compressor and sweat-type refrigerant valves demand proper brazing during field assembly. Suction and liquid lines measure 7/8 inches and 3/8 inches respectively. The plastic PVC exhaust flue simplifies venting compared to high-temperature metal stacks. Electrical service needs 115V single-phase 60Hz power with 23.9 to 40 amp breaker capacity.
Warranty & Reliability
ACiQ covers this system with a 10-year parts warranty when you register the unit online within 60 days of purchase. This extended coverage reflects manufacturer confidence in component reliability. The Goodman evaporator coil carries separate warranty protection, ensuring your indoor cooling coil stays covered even if primary warranty lapses.
