// Bottom Line
This ACiQ system pairs a 97% AFUE modulating furnace with a 14 SEER air conditioner for homeowners seeking reliable heating and cooling without premium pricing. It's particularly well-suited for climate zones requiring both serious heating and moderate cooling capacity.

Review

The ACiQ gas furnace and air conditioner system is a straightforward, mid-market choice for homeowners upgrading their HVAC equipment. This Goodman-backed unit combines heating and cooling into a single package with the upflow configuration suitable for basements and utility closets. It avoids the premium pricing of dual-stage or variable-capacity systems while still delivering respectable efficiency ratings. The modulating burner and variable-speed blower represent thoughtful engineering choices for practical comfort.

On the heating side, the 97% AFUE rating and modulating burner deliver 80,000 BTU with intelligent part-load operation that reduces cycling and fuel consumption. The variable-speed ECM blower reaches 1,600 CFM maximum, which is solid for homes under 2,500 square feet. Cooling capacity reaches 42,000 BTU (3.5 tons) with 14 SEER efficiency using R410A refrigerant. The scroll compressor is reliable, though single-stage means it operates at one speed, missing the efficiency gains of staged systems. Energy Star certification confirms it meets federal baseline requirements.

Pros & Cons

Pros

  • Modulating burner technology delivers 80,000 BTU with variable output, reducing energy waste during partial-load operation
  • 97% AFUE furnace efficiency means heating costs stay low year-round, especially valuable in colder climates
  • Variable-speed ECM blower motor adapts airflow from 0 to 1,600 CFM, improving comfort and reducing runtime
  • 14 SEER cooling rating with R410A refrigerant meets Energy Star standards for AC efficiency
  • 10-year warranty with online registration provides solid protection for both components

Cons

  • 42,000 BTU cooling capacity is actually 3.5 tons, not the advertised 5-ton tonnage, which creates a mismatch in the listing
  • Single-stage compressor means the AC unit runs at full capacity or off, lacking the efficiency of two-stage or variable systems
  • 73 dB noise level during operation is moderately loud for a residential unit, noticeable in quiet homes

Who Should Buy

Best For

Homeowners in regions with cold winters and mild-to-moderate summers who prioritize heating efficiency and want to avoid premium pricing. Contractors installing replacement systems in homes with existing ductwork that supports upflow configuration are also ideal candidates.

Consider Alternatives If

Buyers in hot climates needing robust cooling capacity should look at higher-tonnage units, and those sensitive to equipment noise should compare quieter options first.

Installation

Installation requires standard ductwork connections with 3/8 inch liquid lines and 7/8 inch suction lines, both readily available from HVAC suppliers. The unit operates on 115V single-phase 60 Hz power with a 22 to 35 amp breaker, making it compatible with most residential electrical panels. Plastic or PVC exhaust flue works with the furnace section. Professional installation is strongly recommended to ensure proper refrigerant charging and ductwork sealing.

Warranty & Reliability

ACiQ includes a 10-year parts warranty when you register the unit online after installation. This covers both furnace and air conditioner components, which is competitive for mid-range equipment. Online registration is straightforward and extends protection beyond the standard 5-year coverage. Goodman's evaporator coil carries separate warranty protection under their program terms.

Frequently Asked Questions

What's the actual cooling tonnage of this system? +
The system delivers 42,000 BTU of cooling capacity, which equals 3.5 tons. The listing mentions 5-ton tonnage incorrectly. This 3.5-ton capacity is appropriate for homes between 1,500 and 2,500 square feet in moderate climates.
Can this furnace run on propane instead of natural gas? +
Yes, the burner section is convertible to both propane and natural gas. You must specify which fuel type at time of order, and conversion requires changing the burner assembly. Installation instructions cover the conversion process thoroughly.
How does 97% AFUE compare to newer furnaces? +
97% AFUE is excellent for a modulating gas furnace, though premium units reach 98% to 99%. The 1 to 2 percent difference represents minimal fuel savings in most residential applications, typically $30 to $60 annually.
Should I choose this over a higher-SEER air conditioner? +
The 14 SEER rating works well for moderate cooling climates. If you live in hot regions with extended AC seasons, 16 SEER or higher units will save more on cooling costs, offsetting their higher purchase price within 5 to 8 years.
Does online registration really matter for warranty coverage? +
Yes, registration activates the full 10-year warranty. Without it, coverage defaults to 5 years. Registration takes five minutes online and protects your investment significantly.
