Review
The ACiQ 3.5-ton system represents a practical middle ground in the HVAC market. Badged under Goodman's commercial lines, this horizontal configuration delivers respectable performance without aggressive premium pricing. The 100,000 BTU heating capacity and 42,000 BTU cooling output position it for moderate-sized homes. ACiQ systems gain traction among contractors who value straightforward engineering over flashy marketing.
The furnace's 97% AFUE rating reflects genuine heating efficiency that translates to lower gas bills during extended winter months. The modulating burner adjusts output continuously rather than cycling fully on and off, reducing temperature swings and fuel waste. Its variable-speed ECM blower operates at 2000 CFM maximum while using approximately 25% less energy than conventional fixed-speed motors. The 13 SEER1 cooling efficiency is competent rather than cutting-edge, acceptable for mixed climates.
Pros & Cons
Pros
- 97% AFUE furnace efficiency beats most mid-range competitors, reducing heating fuel costs significantly
- Modulating burner stages output precisely, avoiding the on-off cycling that wastes energy
- Variable-speed ECM blower reaches 2000 CFM maximum while consuming less electricity than fixed-speed motors
- Horizontal configuration fits tight attic and basement spaces where vertical units won't work
- PVC exhaust flue compatibility simplifies installation in retrofit applications without masonry chimneys
Cons
- 13 SEER1 cooling rating is adequate but trails high-efficiency models at 16+ SEER2 by 20-30% in cooling efficiency
- Single-stage condenser cannot modulate cooling capacity like furnace modulates heating, reducing part-load efficiency
- 75 dB noise level ranks on the louder side for residential installations, potentially noticeable in quiet homes
Who Should Buy
Best For
Homeowners in colder climates who heat more than they cool should prioritize this furnace's exceptional 97% AFUE rating. Contractors installing horizontal units in space-constrained attics or basements will appreciate the compact 21-inch height and flexible exhaust venting options.
Consider Alternatives If
Skip this system if your primary concern is cooling efficiency in hot climates, as the 13 SEER1 rating and single-stage condenser won't compete with variable-capacity systems rated 16 SEER2 or higher.
Installation
This horizontal unit requires 208 or 230V single-phase power with 23.9 to 40-amp breaker capacity. PVC exhaust venting simplifies installation in homes lacking traditional masonry chimneys. The compact 21-inch height fits standard attic cavities. Suction line insulation comes pre-wrapped at 3/8 inch thickness. Standard sweat valve connections require basic soldering skills or professional installation.
Warranty & Reliability
ACiQ backs this system with 10 years parts and labor coverage through online registration, matching or exceeding most mid-tier manufacturers. The extended warranty covering the integrated evaporator coil is valuable, though owners must complete registration within 30 days of installation to activate full protection.
