Review
The ACiQ 4-ton upflow furnace and air conditioner system occupies solid middle ground in the residential HVAC market. Manufactured by Goodman under the budget-friendly ACiQ label, this combo delivers 120,000 BTU of heating and 48,000 BTU of cooling in one compact upflow cabinet. At 30 inches tall and 120 pounds, it fits standard basement or closet installations. The unit accepts both natural gas and propane, making it versatile for different fuel infrastructures across North America.
Performance numbers tell a practical story. The furnace operates at 96% AFUE, meaning 96 cents of every heating dollar actually heats your home versus 80-85% on older equipment. The two-stage burner modulates output instead of simply on-off cycling, improving comfort and reducing short-cycling waste. Cooling comes via a single-stage scroll compressor delivering 14 SEER with R454B refrigerant. The variable-speed ECM blower runs at a quiet 74 dB while moving up to 2000 CFM, adapting airflow to actual heating and cooling demands rather than running constantly at maximum.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% units
- Variable-speed ECM blower motor provides quiet operation at 74 dB while optimizing airflow
- Two-stage burner modulates heating output for better comfort and fuel economy
- 14 SEER cooling meets modern baseline efficiency standards with R454B refrigerant
- PVC exhaust option simplifies venting in many retrofit installations
Cons
- 14 SEER rating is baseline modern efficiency, not high-tier (competitors offer 16-18 SEER)
- Single-stage condenser cannot modulate cooling output for variable load conditions
- No Energy Star certification despite 96% AFUE furnace efficiency
- Requires 26.4 to 45 amp electrical service, which older homes may need panel upgrades
Who Should Buy
Best For
Contractors installing comfort systems in moderate climates where balanced heating and cooling matter equally. Homeowners replacing broken equipment who want reliable, efficient operation without spending 20-30% extra for premium tiers.
Consider Alternatives If
Buyers in hot climates prioritizing cooling efficiency or those seeking cutting-edge variable-capacity compressors should explore higher SEER models.
Installation
This upflow configuration suits basements and utility closets where ducting runs upward. The plastic or PVC exhaust flue requirement simplifies venting compared to metal alternatives, reducing installation cost and complexity. Electrically, you'll need 208-230V single-phase 60Hz service with circuit breakers sized between 26.4 and 45 amps. Standard R-22 to R454B conversions require new lineset sizing, so calculate 3/8-inch liquid and 7/8-inch suction lines with 3/8-inch insulation. Most contractors complete installation in one working day.
Warranty & Reliability
ACiQ backs this unit with 10 years of parts coverage upon online registration. That's competitive for mid-tier equipment, though premium brands sometimes offer 12-15 year terms. The Goodman evaporator coil carries separate documentation, which you'll need for any refrigerant-side claims. Registration is mandatory, so save your receipt and complete it promptly after installation.
