Review
The ACiQ 4 ton upflow furnace and air conditioner system occupies a practical middle ground in the HVAC market. This Goodman-manufactured combo delivers respectable efficiency ratings without charging premium prices. At 120,000 BTU heating capacity and 48,000 BTU cooling output, it's sized for average residential applications. The upflow configuration with A-coil design makes it a natural retrofit choice for homes with basement or crawlspace installations requiring horizontal ductwork.
Performance specs justify the design choices here. The furnace hits 96% AFUE, meaning 96 cents of every heating dollar goes toward warmth rather than exhaust losses. Cooling efficiency reaches 14 SEER1, positioning this system ahead of 13 SEER baseline units. Two-stage burner operation and the ECM multi-speed blower motor enable efficient part-load performance. The 2000 CFM maximum airflow handles proper air circulation without excessive velocity noise or ductwork stress.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% models
- 14 SEER cooling meets modern efficiency standards while avoiding ENERGY STAR complexity
- Two-stage burner and ECM blower motor enable precise comfort and lower runtime noise
- PVC/plastic exhaust flue compatible with modern condensing furnace venting codes
- Multi-speed ECM blower provides better humidity control and comfort than single-speed alternatives
Cons
- Single-stage condenser limits part-load cooling efficiency during mild weather operation
- 5 ton tonnage mismatch with 4 ton rating creates potential oversizing complications for smaller homes
- 74 dBA noise level ranks average, not particularly quiet for upflow installations near living spaces
- No ENERGY STAR certification despite strong AFUE and SEER ratings
Who Should Buy
Best For
Contractors performing furnace replacements on homes with upflow ductwork layouts and standard single-phase 208-230V electrical service. Homeowners seeking efficient dual heating and cooling in the $0 price range without premium brand markup.
Consider Alternatives If
Anyone needing variable-speed cooling, ENERGY STAR certification, or systems with noise levels below 70 dBA should evaluate competing models.
Installation
Installation proves straightforward for experienced HVAC crews. The 30-inch height, 24.5-inch width, and 21-inch depth fit standard basement mechanical spaces or utility closet applications. PVC flue venting simplifies exhaust routing compared to traditional metal ductwork. Electrical demand spans 26.4 to 45 amp breakers at 208-230V single-phase, matching most residential electrical panels. Refrigerant lines require 3/8-inch and 7/8-inch sizing with 3/8-inch insulation thickness on suction lines.
Warranty & Reliability
ACiQ backs this system with a 10-year parts warranty upon online registration, standard coverage for mid-tier equipment. This protects major components like the scroll compressor, furnace heat exchanger, and coil against manufacturing defects. Goodman evaporator coil warranty documentation ships separately. No labor coverage means homeowners bear service costs if repairs exceed parts replacement.
