Review
The ACiQ 3.5-ton system (marketed with Goodman branding) is a mid-market furnace-condenser combo designed for homeowners seeking reliable heating without premium-tier pricing. Its 96% AFUE rating places it in the high-efficiency category for gas furnaces, appealing to cost-conscious buyers focused on winter heating costs. The variable-speed ECM blower is the standout feature, automatically adapting to heating and cooling demand rather than running at fixed speeds. This configuration makes sense for contractors installing upflow systems in standard basement or closet installations.
Heating performance delivers 100,000 BTU output with two-stage burner modulation, allowing the furnace to run at reduced capacity during mild weather and ramp up during cold snaps. The cooling side produces 42,000 BTU at 13 SEER using R410A refrigerant and a reciprocating compressor, adequate for moderate climates but not exceptional for high-cooling-demand regions. Maximum airflow reaches 2000 CFM with the variable blower, and the unit operates at 75 dBA, relatively quiet for this class. Electrical requirements are straightforward at 208/230V single-phase.
Pros & Cons
Pros
- 96% AFUE heating efficiency means only 4% energy loss, significantly reducing winter fuel costs
- Variable-speed ECM blower automatically adjusts to demand, improving comfort and lowering electricity consumption
- Two-stage burner provides modulating heat for smoother temperature control and reduced cycling
- PVC exhaust compatibility simplifies installation in homes with plastic vent systems
- 10-year warranty with online registration offers solid coverage for system longevity
Cons
- 13 SEER cooling is mid-range efficiency, not high-tier like 16+ SEER alternatives
- Single-stage condenser limits cooling flexibility compared to two-stage models
- Not Energy Star certified, missing potential rebates in some utility programs
Who Should Buy
Best For
Homeowners in mild to moderate climates prioritizing heating efficiency over cooling performance, or those replacing older furnaces in homes already equipped for PVC exhaust. Contractors installing systems in new construction or retrofits where upflow configuration fits floor plans.
Consider Alternatives If
Homeowners in hot climates where cooling dominates utility bills should seek higher SEER ratings, and those without PVC exhaust capability should look at units supporting metal flue options.
Installation
Installation is contractor-friendly with PVC/plastic exhaust compatibility, eliminating the cost and complexity of metal venting in many homes. The upflow configuration suits standard basement or utility closet placement. Dimensions of 30 inches tall, 21 wide, and 21 deep fit most standard furnace spaces. Suction and liquid line sizes of 7/8 inch and 3/8 inch respectively are manageable with standard tools. Breaker sizing between 23.9 and 40 amps keeps electrical work routine.
Warranty & Reliability
ACiQ backs this system with a 10-year parts warranty when registered online, a respectable duration for mid-market equipment. The Goodman evaporator coil carries separate warranty coverage, protecting the cooling component. This warranty level provides reasonable peace of mind without matching top-tier manufacturers like Carrier or Lennox, which sometimes offer longer terms. Registration is required to activate coverage.
