// Bottom Line
This ACiQ system delivers solid efficiency with a 96% AFUE furnace and 13 SEER cooling for homeowners in moderate climates seeking reliable heating and cooling without premium pricing. Best suited for contractors needing a dependable mid-range option that handles both heating and cooling in a compact upflow configuration.

Review

ACiQ's 4-ton gas furnace and air conditioning system bridges affordability and competence in the mid-market HVAC space. This upflow unit combines a 96% AFUE furnace capable of 100,000 BTU heating output with a 13 SEER air conditioner rated for 48,000 BTU cooling. The compact 30-inch height and 21-inch width fit standard utility closets and basement installations. ACiQ positions this model as a practical replacement for older Goodman units, appealing to cost-conscious homeowners and contractors seeking reliable combined heating and cooling without premium brand markup.

Performance-wise, the 96% AFUE rating places this furnace in the high-efficiency category, converting nearly all fuel to usable heat while modern venting systems handle the cooler exhaust safely. The two-stage burner reduces energy consumption during partial heating loads, and the multi-speed ECM blower motor adjusts fan speed based on demand rather than running constantly at full capacity. Cooling efficiency at 13 SEER is respectable for moderate climates but moderately trails 15-16 SEER competitors by 15-20%. The reciprocating compressor and single-stage condenser provide straightforward reliability, though they lack the part-load efficiency of scroll or variable-capacity designs.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency means lower heating costs and minimal energy waste, saving approximately 10-15% annually versus 80% AFUE models
  • 13 SEER cooling rating provides respectable air conditioning efficiency for moderate climate zones at an accessible price point
  • Multi-speed ECM blower motor adjusts airflow dynamically, improving comfort and reducing runtime versus single-stage motors
  • Two-stage burner allows modulating heat output, reducing short-cycling and improving indoor temperature consistency
  • PVC/plastic exhaust flue compatibility simplifies installation in homes with existing plastic venting or newer construction

Cons

  • 13 SEER1 rating is acceptable but not exceptional, trailing 15-16 SEER models by roughly 15-20% cooling efficiency
  • Single-stage condenser limits cooling modulation on mild days, running at full capacity even during partial-load conditions
  • 76 dB noise level is moderately loud, noticeably audible from 10-15 feet away during operation
  • Not Energy Star certified, missing qualification that some utility rebate programs require

Who Should Buy

Best For

Homeowners in moderate climates (zones 4-6) replacing aging 80-90% AFUE systems who want meaningful efficiency gains without top-tier pricing. Contractors installing systems in rental properties or mid-range residential builds where balanced performance and cost matter more than premium efficiency ratings.

Consider Alternatives If

Buyers in hot climates needing aggressive cooling efficiency should evaluate 15+ SEER units, and homeowners chasing Energy Star certification must look elsewhere as this model does not qualify.

Installation

Installation is straightforward for experienced HVAC technicians. The upflow configuration requires standard ductwork connections with 1600 CFM maximum airflow capacity. Refrigerant lines use industry-standard 3/8-inch liquid and 1 1/8-inch suction sizes, with 50 feet of insulated suction line included. Electrical requirements are 208/230 V single-phase 60 Hz, needing a 26.3 to 45-amp breaker. PVC flue venting simplifies installation compared to metal venting in retrofit applications.

Warranty & Reliability

ACiQ provides a 10-year parts warranty with online registration, covering the furnace and condenser unit against defects. This matches industry standard coverage for mid-range equipment but falls short of 12-year extended warranties offered by premium brands. Online registration is required to activate coverage, so homeowners must complete this step immediately after installation to protect their investment.

Frequently Asked Questions

How much can I expect to save on heating costs with 96% AFUE compared to my old 80% AFUE furnace? +
At 96% AFUE versus 80%, you lose roughly 4 percentage points of efficiency. On a $1,500 annual heating bill, that difference equals approximately $75-$90 in annual savings. Over a 15-year furnace life, that totals $1,125-$1,350, making this efficiency level worthwhile for most climates.
Will this system fit in a standard 30-inch utility closet or tight basement space? +
Yes. At 30 inches tall, 21 inches wide, and 21 inches deep, this upflow furnace fits most standard utility closet dimensions. You'll need 6-12 inches clearance above for plenum ducting and service access. Verify your available space before ordering to ensure safe installation.
Is 13 SEER cooling sufficient for hot climates, or should I upgrade to a higher-rated unit? +
13 SEER works adequately in moderate climates, zones 4-6. In hot climates (zones 9-10), a 15-16 SEER unit reduces cooling costs 15-20% annually. If air conditioning runtime exceeds 4 months yearly, investing in higher SEER provides faster payback through lower electric bills.
How does the two-stage burner improve comfort and efficiency compared to single-stage furnaces? +
Two-stage burners run at reduced capacity during mild heating days, reducing short-cycling and temperature swings. This means steadier indoor temps, fewer furnace starts (reducing wear), and slightly lower gas consumption during partial-load operation. Single-stage units blast full heat on/off, creating noticeable temperature fluctuations.
What does the 10-year warranty actually cover, and are there exclusions I should know about? +
The 10-year parts warranty covers manufacturing defects in the furnace and condenser. It does not cover labor, refrigerant, or damage from improper installation. You must register online to activate coverage, a step many homeowners overlook, leaving themselves unprotected.
