Review
ACiQ's Goodman-branded combo system lands in a crowded mid-tier HVAC market where efficiency matters but premium pricing doesn't make sense for every buyer. At 97% AFUE with modulating burners and a variable-speed blower, this downflow furnace appeals to homeowners tired of utility waste. The matching 13 SEER air conditioner rounds out the package for year-round climate control, though the heating side is clearly the stronger suit.
The furnace delivers 100,000 BTU heating output with modulating stages that ramp up or down based on thermostat demand, cutting the on-off cycling common in single-stage units. The AC side contributes 42,000 BTU cooling across a single compressor stage, achieving 13 SEER efficiency with R410A refrigerant. The variable-speed ECM blower reaches 2000 CFM maximum, intelligently matching airflow to seasonal needs rather than running constantly at full speed, which translates to quieter operation and lower electrical draw on part-load days.
Pros & Cons
Pros
- 97% AFUE furnace efficiency exceeds most competitors and minimizes fuel waste on heating cycles
- Modulating burner adjusts output in real-time rather than running full blast, improving comfort and reducing short-cycling
- Variable-speed ECM blower motor delivers up to 2000 CFM and adapts to actual heating/cooling demand
- 13 SEER AC unit with R410A refrigerant meets current efficiency standards for most markets
- PVC exhaust compatibility simplifies venting in retrofit applications without expensive metal ductwork
- AHRI-certified pairing (certificate 7424272) ensures matched components work reliably together
Cons
- 13 SEER is competitive but not cutting-edge, SEER2 equivalent would be approximately 11, trailing 16+ SEER single-stage units
- Single-stage AC compressor cannot modulate like the furnace, limiting efficiency during partial-load cooling periods
- 5-ton cooler paired with stated 3.5-ton rating creates a mismatch that may affect system balance and efficiency claims
- 75 dB noise level is noticeably loud during operation, potentially problematic in open-concept homes
Who Should Buy
Best For
Homeowners in colder climates where heating dominates should prioritize this system, as the 97% AFUE furnace delivers the most value during winter months. It suits budget-conscious buyers who want proven reliability and don't need top-tier cooling performance.
Consider Alternatives If
Anyone in hot climates or seeking maximum AC efficiency should look elsewhere, as the single-stage compressor and 13 SEER cooling don't match the heating prowess.
Installation
Downflow configuration fits tight attic spaces or closets where side-return air isn't possible. The system requires 115V single-phase 60Hz power with breaker sizing between 23.9 and 40 amps, making it compatible with standard residential panels. PVC exhaust venting eliminates expensive metal ductwork modifications. A-coil design simplifies evaporator integration with most existing indoor blower cabinets. Refrigerant lines use standard 3/8-inch liquid and 7/8-inch suction tubing with sweat valve connections.
Warranty & Reliability
ACiQ provides a 10-year parts warranty when you complete online registration after installation. This is solid coverage that matches or exceeds most mid-market competitors. Ten years typically covers compressor burnout, coil leaks, and component failure, though labor is the buyer's responsibility. Register promptly after commissioning to activate coverage and maintain documentation for any future claims.
