// Bottom Line
This ACiQ unit targets budget-conscious homeowners and contractors seeking dependable heating and cooling without premium efficiency ratings. The 80% AFUE furnace and 14 SEER condenser deliver respectable performance for moderate climates where heating costs matter less than upfront savings.

Review

The Goodman 5-ton system under the ACiQ brand represents a pragmatic middle ground in the HVAC market. Designed for horizontal installation in attics and tight spaces, this unit pairs an 80% AFUE two-stage furnace with a 14 SEER single-stage air conditioner. It's built on proven scroll compressor technology and uses the modern R454B refrigerant, making it a reliable workhorse for contractors balancing budget constraints with customer expectations.

Performance metrics reveal a competent but dated approach to climate control. The furnace delivers 58,000 BTU of heating output across two stages, while the condenser produces 57,000 BTU of cooling. The 14 SEER rating meets minimum efficiency standards but falls short of today's 16-18 SEER mainstream units. The multi-speed blower keeps noise to 77 dB, a reasonable trade-off for a budget system, though still perceptible during full-load operation in quiet spaces.

Pros & Cons

Pros

  • Two-stage gas furnace with 58,000 BTU heating output provides consistent warmth during cold snaps
  • 14 SEER cooling delivers 57,000 BTU capacity, adequate for 5-ton applications in mixed climates
  • R454B refrigerant is drop-in compatible, avoiding costly system redesigns for future replacements
  • Multi-speed blower motor reduces runtime noise to 77 dB and improves comfort control
  • Horizontal A-coil configuration fits tight attic or crawlspace installations with 38.25-inch height
  • 10-year parts warranty with online registration protects against early compressor or heat exchanger failure

Cons

  • 80% AFUE is outdated by modern standards, costing 10-15% more annually than 95% AFUE systems in cold regions
  • Single-stage condenser cycles on and off rather than modulating, reducing efficiency on mild 50-70°F days
  • 77 dB noise level noticeably louder than high-efficiency competitors, problematic for bedroom-adjacent units
  • Not Energy Star certified, limiting appeal to eco-conscious buyers and LEED-focused projects
  • Requires 34.6 to 60 amp breaker, demanding dedicated electrical service many older homes lack

Who Should Buy

Best For

Homeowners in moderate climates replacing failed 10-15 year old systems who prioritize upfront cost over long-term efficiency. Contractors serving price-sensitive residential and light commercial clients where heating and cooling demands are moderate.

Consider Alternatives If

Anyone in cold climates (Minnesota, Wisconsin, upstate New York) should skip the 80% AFUE furnace and invest in 95%+ efficiency. Energy-conscious buyers targeting sub-15 year payback periods will see better ROI with 16+ SEER systems.

Installation

Installation complexity is moderate. The horizontal A-coil measures 38.25 inches tall by 35.5 inches wide and deep, fitting standard attic rough-ins. Technicians need 3/8-inch liquid lines and 1 1/8-inch suction lines with half-inch insulation wrap. Electrical demand ranges from 34.6 to 60 amps at 208-230V single-phase, requiring a dedicated breaker in most homes. Metal exhaust flue connection is mandatory for the furnace.

Warranty & Reliability

ACiQ provides a 10-year parts warranty when you register online after installation. Coverage includes compressor failure and heat exchanger defects but excludes wear items like blower motors and capacitors. Online registration is straightforward and extends protection significantly beyond the typical 5-year baseline, offering reasonable peace of mind for a budget-tier system.

Frequently Asked Questions

How does the 14 SEER rating compare to newer systems? +
14 SEER is adequate but outdated. Today's efficient units deliver 16-18 SEER. For every point of SEER improvement, expect 5-7% lower cooling electricity use. In hot climates, the gap widens significantly, making newer systems worthwhile over 12-15 years.
Will this 5-ton unit fit my attic space? +
Likely yes. The 38.25-inch height and 35.5-inch width fit most modern attic installations. However, measure your rough-in opening first. The upflow/horizontal configuration works in tight spots where vertical-only units fail, a key advantage for retrofit jobs.
Why is 80% AFUE furnace efficiency concerning? +
Modern codes push 90-95% AFUE. At 80%, you lose 20 cents per dollar as exhaust heat. In Minnesota winters, this costs $300-500 extra yearly versus a 95% unit. Over 20 years, that's $6,000-10,000 in wasted gas, making the initial savings illusory.
Is R454B refrigerant better than R410A? +
R454B is a modern drop-in replacement with similar performance but lower global warming potential. For most contractors, the difference is negligible on this single-stage unit. Future regulations favor R454B, so you're ahead of compliance curves by two to five years.
Does the 10-year warranty cover labor costs? +
No. ACiQ covers parts only. Labor is your responsibility. Some dealers bundle extended labor warranties for $200-400. Read your registration carefully, as many claims require proof of professional installation and annual maintenance.
