Review
The ACiQ 3-ton horizontal furnace and air conditioner system combines Goodman's proven reliability with modern efficiency standards at an accessible price point. This unit targets homeowners and contractors who need dependable year-round climate control without premium features. The modulating furnace and single-stage compressor represent the middle ground of the HVAC market, offering measurable efficiency gains over older equipment while keeping installation and maintenance straightforward.
Efficiency numbers tell the real story here. The furnace delivers 97% AFUE, meaning only 3% of natural gas or propane fuel gets wasted as exhaust. Cooling capacity reaches 36,000 BTU at 13 SEER efficiency, which qualifies for Energy Star certification and performs reliably with R454B refrigerant. The variable-speed blower motor adjusts CFM up to 2000 based on demand, reducing runtime and electricity consumption compared to fixed-speed alternatives. These specs translate to approximately 15 to 25 percent lower energy bills compared to 80% AFUE furnaces from the early 2000s.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means you lose only 3% of heating fuel to exhaust, translating to lower winter bills
- Modulating burner adjusts heating output in stages rather than on/off, reducing temperature swings and improving comfort
- Variable-speed ECM blower motor runs quieter and consumes less electricity than fixed-speed alternatives
- 13 SEER cooling efficiency qualifies for Energy Star, with R454B refrigerant meeting current EPA standards
- 10-year warranty with online registration provides solid peace of mind
- Sweat connections and 3/8 inch liquid line size simplify field repairs for experienced technicians
- Upflow/horizontal configuration fits basements, attics, and crawl spaces
Cons
- Single-stage compressor in the AC unit means the air conditioner runs at full capacity or off, lacking the efficiency gains of two-stage cooling
- 3.5 ton rating slightly oversizes this unit relative to the 3 ton claim, potentially causing short-cycling in smaller homes
- 74 dB noise level is audible during operation, noticeably louder than premium variable-capacity units
Who Should Buy
Best For
Homeowners replacing failed furnaces or AC systems where budget matters more than premium features, and contractors building starter systems for rental properties or modest homes. This combination delivers solid efficiency and reliability without premium pricing.
Consider Alternatives If
Buyers wanting whisper-quiet operation, homes with extreme climate demands requiring two-stage cooling, or those prioritizing the absolute lowest operating costs should explore variable-capacity alternatives despite their higher upfront cost.
Installation
This horizontal configuration requires 30 feet of clearance for suction line insulation and proper airflow. Sweat connections use 3/8 inch liquid lines and 7/8 inch suction lines, standard sizes that most HVAC shops stock readily. Electrical setup needs 115V single-phase 60 Hz power with a breaker between 19.1 and 30 amps. PVC exhaust flue on the right side simplifies venting through walls or roofs. Installation typically takes one technician four to six hours for a straightforward replacement.
Warranty & Reliability
The 10-year parts and labor warranty covers defects in materials and workmanship when you register the unit online within 90 days of installation. This protection applies to compressor failure, heat exchanger cracks, and component failures, though normal wear and refrigerant loss from leaks carry different terms. The warranty transfers with home sales, adding value if you're upgrading before resale.
