// Bottom Line
This ACiQ unit is ideal for homeowners replacing older Goodman systems or those prioritizing heating efficiency in moderate climates. The 97% AFUE and modulating burner deliver measurable gas savings, though the 13 SEER cooling efficiency is middle-of-the-road for 2024 standards.

Review

The ACiQ 5-ton system represents a solid mid-tier option for homeowners seeking reliable heating and cooling in a single package. Built on Goodman's platform with modern enhancements, this downflow unit handles 100,000 BTU heating output and 60,000 BTU cooling across 2000 maximum CFM. The unit weighs 120 pounds and fits standard 21x21x30 inch spaces, making it compatible with most residential installations. At this price point, it competes against entry-level premium brands while maintaining the service accessibility contractors value.

Heating performance is the standout feature, with 97% AFUE efficiency and a modulating burner that adjusts flame output continuously rather than cycling on and off. This reduces temperature swings and cuts energy consumption compared to single-stage alternatives. Cooling delivers 13 SEER1 efficiency, adequate but not exceptional for 2024 standards. The variable-speed ECM blower motor maximizes comfort by adjusting airflow dynamically, and R454B refrigerant ensures compliance with environmental regulations. Electrical requirements are 208-230V single-phase 60 Hz, well within standard residential service.

Pros & Cons

Pros

  • 97% AFUE heating efficiency means only 3% of fuel wasted, translating to real savings on gas bills
  • Modulating burner adjusts flame intensity automatically, reducing energy waste and maintaining comfort
  • Variable-speed ECM blower motor fine-tunes airflow from 0 to 2000 CFM for better temperature control
  • R454B refrigerant meets current environmental standards and future regulations
  • Plastic PVC exhaust venting reduces installation complexity compared to metal vent requirements
  • 10-year warranty with online registration provides solid consumer protection

Cons

  • 13 SEER cooling rating lags behind 15-16 SEER competitors by 15-20% efficiency
  • Single-stage condenser cannot modulate cooling capacity, only runs full or off
  • 77 dB noise level is moderately loud for residential units, noticeable from nearby rooms
  • No ENERGY STAR certification despite high heating efficiency

Who Should Buy

Best For

Homeowners in cold or moderate climates replacing failed Goodman furnaces, or those upgrading systems 10-15 years old will see immediate heating bill reductions. Contractors valuing installation speed appreciate the PVC venting and straightforward downflow configuration.

Consider Alternatives If

Buyers in hot climates prioritizing cooling efficiency or those seeking premium 16+ SEER systems should compare higher-efficiency alternatives.

Installation

This downflow unit requires PVC or plastic exhaust venting, which simplifies installation since contractors avoid complex metal flue work. The A-coil configuration integrates standard liquid and suction lines with 3/8 inch and 7/8 inch diameters respectively. Breaker sizing ranges from 32.8 to 45 amps, fitting most household electrical panels. AHRI certification 7424272 confirms proper matching with compatible coils and condensers.

Warranty & Reliability

The 10-year parts warranty requires online registration within 30 days of installation. This covers compressor, heat exchanger, and most internal components, providing reasonable consumer protection. Registration is straightforward and enables extended support eligibility. Labor and refrigerant are typically not covered under standard terms.

Frequently Asked Questions

How much can I save on heating costs with 97% AFUE? +
A 97% AFUE furnace wastes only 3% of fuel input versus 80-85% AFUE units wasting 15-20%. For homes using 80 million BTU annually, this translates to approximately 1.2-1.6 million BTU in avoided waste, saving $150-250 yearly depending on local gas rates and usage patterns.
Can this unit be installed in an upflow configuration? +
Yes, the specs list upflow/downflow capability. However, verify proper A-coil orientation with your HVAC contractor during installation. Incorrect positioning reduces airflow efficiency and may void warranty coverage if not AHRI-matched correctly.
Is 13 SEER cooling competitive for 2024? +
No, 13 SEER is entry-level for new systems. Most quality mid-tier units now offer 15-16 SEER. You'll sacrifice approximately 15-20% cooling efficiency versus newer alternatives, though heating efficiency remains excellent. Consider your climate's cooling demands before purchasing.
How does this compare to Lennox or Carrier equivalents? +
This ACiQ unit undercuts premium brands on price while matching heating efficiency. However, Lennox and Carrier typically offer higher SEER cooling ratings (15-18) and quieter operation (72-74 dB versus 77 dB). Choose ACiQ for budget-conscious heating priorities, not cooling performance.
Does the warranty cover refrigerant leaks? +
The 10-year warranty covers compressor and internal component failures. Refrigerant leaks may be covered if caused by manufacturing defects, but diagnostic and recharge labor are customer responsibility. Review your installer's extended service agreement for complete leak coverage.
