// Bottom Line
This ACiQ combo system is ideal for homeowners in moderate climates who want solid heating efficiency without premium cooling specs. The 96% AFUE furnace excels in winter, while the 13 SEER condenser handles summer adequately at a reasonable price point.

Review

The ACiQ 5-ton combo system pairs a Goodman furnace with an ACiQ condenser into one integrated heating and cooling package. This downflow configuration is purpose-built for homes without basements, fitting into closets or side-mounted installations. It's marketed as a value option, positioned between budget-tier equipment and high-efficiency systems that cost 30 to 50 percent more. The 96% AFUE furnace is the real standout here, promising minimal waste during winter operation.

Heating output sits at 100,000 BTU with two-stage burner capability, meaning it can run at partial capacity when demand is light. The cooling side delivers 60,000 BTU using 13 SEER efficiency and R454B refrigerant. That 13 SEER rating is respectable but not exceptional, trailing modern 14 to 16 SEER units. The variable-speed ECM blower motor is excellent, ramping from zero to 2000 CFM as needed. This pairing works well in temperate zones but will struggle in climates with extreme summers.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency captures 96 cents of every heating dollar, translating to real savings in colder months
  • Variable-speed ECM blower motor optimizes airflow between 0 and 2000 CFM, improving comfort and reducing short cycling
  • Two-stage burner allows the furnace to run at 60% capacity during mild weather, cutting energy waste
  • Energy Star certified system qualifies for utility rebates in many regions, offsetting upfront costs
  • 10-year comprehensive warranty with online registration provides solid protection against manufacturing defects
  • Downflow/A-coil configuration works in basements and closets, offering installation flexibility that upflow units cannot match

Cons

  • 13 SEER cooling rating lags behind 14-16 SEER alternatives, making this suboptimal for hot, humid climates where AC runs constantly
  • Single-stage compressor cannot modulate capacity, so it cycles on and off rather than running steadily, reducing efficiency in shoulder seasons
  • 77 dB noise level is noticeably louder than variable-capacity units, which may concern noise-sensitive homeowners
  • R454B refrigerant requires specialized handling and service technician training, limiting repair shop options in rural areas

Who Should Buy

Best For

Homeowners in mixed climates (northern and central regions) who prioritize winter heating efficiency and need flexible installation options. This system makes sense if your heating season is long and your cooling needs are moderate, or if rebates significantly reduce your out-of-pocket cost.

Consider Alternatives If

Anyone in hot climates like Arizona, Florida, or Louisiana should choose a 15+ SEER unit instead, and homes with noise concerns should audition this unit before purchasing.

Installation

This downflow unit requires 3/8 inch and 7/8 inch refrigerant lines with sweat-type valve connections. Electrical needs are modest, 115V single-phase at 32.8 to 45 amp breaker range. PVC or plastic exhaust flue is mandatory. Installation complexity is moderate, assuming your HVAC tech is familiar with R454B handling and can fit the 30 by 21 by 21 inch unit into your target location. Field commissioning typically takes one to two hours.

Warranty & Reliability

ACiQ backs this unit with a 10-year parts warranty upon online registration. Coverage includes the condenser, coil, and compressor. No labor is included, so you'll pay service call rates for repairs. This warranty is competitive within the value segment but shorter than premium manufacturers offering 12 or 15 year terms. Registration is straightforward and must be completed within 30 days of installation.

Frequently Asked Questions

How does 96% AFUE compare to my old furnace? +
Most furnaces installed before 2010 operated at 78 to 85% AFUE, wasting one dollar in five. This 96% unit recovers nearly all heat, cutting fuel consumption roughly 15 percent compared to an 80% unit. Annual savings depend on your gas rates and heating degree days, typically ranging from 200 to 600 dollars annually in cold climates.
Can this system handle my home's existing ductwork? +
Yes, provided your ducts accommodate 2000 CFM maximum airflow. Undersized ductwork will reduce efficiency. Have your contractor measure duct area and velocity. For 5-ton systems, ducts should total at least 1.5 square feet of opening. Ductwork inspection before installation is essential to avoid performance issues.
Is 13 SEER enough cooling for summer? +
Adequate in temperate zones where AC runs 4 to 6 months, but insufficient in hot, humid climates requiring 14 to 16 SEER. Your cooling costs will be 10 to 20 percent higher than high-efficiency models. If summer humidity is a priority, choose a unit with at least 14 SEER and variable-capacity compressor.
Does this work with smart thermostats or zone control? +
Yes. The variable-speed blower accepts signals from modern smart thermostats. However, the single-stage compressor limits zoning benefits. For true multi-zone performance, you'd need a variable-capacity condenser, which adds cost but improves comfort and efficiency significantly.
What happens if I don't register for the warranty? +
Without registration, coverage drops to 5 years instead of 10. Register online immediately after installation. Proof of purchase and installation date are required. Skipping registration effectively halves your protection window, making registration a simple but important step.
