// Bottom Line
This system targets budget-conscious homeowners and contractors seeking affordable cooling and heating without premium features. At $647, it delivers respectable 13 SEER cooling and 97% AFUE heating efficiency for entry-level residential applications, though it lacks the variable-capacity cooling and advanced controls found in higher-tier units.

Review

The ACiQ-36-EHPD-UPG is a stripped-down 3-ton combo system positioned aggressively in the budget segment. Manufactured under the Goodman brand, it replaces three older GSX models and arrives as a complete heating-cooling package for upflow installations. At $647, it undercuts most name-brand competitors by $300-500, making it attractive to price-sensitive buyers and contractors managing tight job margins. The unit carries Energy Star certification and a 10-year warranty with registration.

Performance specs reveal solid but unspectacular numbers across the board. Cooling output hits 36,000 BTU with 13 SEER1 efficiency, while heating delivers 80,000 BTU at 97% AFUE with modulating burner control. The variable-speed ECM blower handles up to 1600 CFM, allowing the system to adapt airflow for better dehumidification. However, the single-stage reciprocating compressor cannot modulate cooling capacity, forcing on-off cycling that compromises humidity control in humid climates. Operating noise registers 74 dB at full load, noticeably louder than quieter premium units.

Pros & Cons

Pros

  • Exceptionally low price point at $647 makes it accessible for cost-conscious buyers and rental properties
  • 97% AFUE with modulating burner stages minimizes heating energy waste and improves comfort during cold months
  • Variable-speed ECM blower motor allows flexible airflow up to 1600 CFM, improving dehumidification and temperature consistency
  • Energy Star certification confirms efficiency standards meet government benchmarks
  • 10-year warranty with online registration provides reasonable coverage for the price tier
  • R454B refrigerant is modern and environmentally responsible compared to older R22 or R410A alternatives

Cons

  • 13 SEER1 efficiency lags behind 14-16 SEER systems now standard in mid-range offerings, increasing annual cooling costs
  • Single-stage compressor cannot modulate cooling capacity, resulting in on-off cycling that reduces humidity control and comfort
  • 74 dB noise level at full load is noticeably loud, potentially problematic for installations near bedrooms or living spaces
  • Limited manufacturer documentation and fewer aftermarket part options compared to major Goodman flagship models

Who Should Buy

Best For

This system suits homeowners upgrading from older units in moderate climates where cooling demands are seasonal rather than intense. It also works well for landlords managing multi-unit properties where upfront equipment cost matters more than peak efficiency.

Consider Alternatives If

Buyers in hot climates requiring heavy cooling runtime or those prioritizing quiet operation should explore 14-16 SEER two-stage or variable-capacity systems instead.

Installation

Installation complexity is straightforward for experienced HVAC technicians. The A-coil configuration supports upflow or horizontal mounting in attics or closets. Suction and liquid line sizes of 7/8 inch and 3/8 inch respectively are standard, with 3/8-inch insulation already applied to suction lines. Electrical requirements are minimal: 115V single-phase 60Hz service with 19.1-30 amp breaker sizing. PVC exhaust flue venting is required. Field connections take 4-6 hours including refrigerant lines and ductwork integration.

Warranty & Reliability

The 10-year parts and compressor warranty provides reasonable protection once you register the unit online within 30 days of installation. This covers defects in materials and workmanship but excludes labor, refrigerant recharging, and damage from improper installation or maintenance. Extended coverage options are not advertised. Warranty claims require original purchase documentation and proof of professional installation.

Frequently Asked Questions

How does 13 SEER1 compare to modern systems? +
13 SEER1 is entry-level by 2024 standards. Most new mid-range units offer 14-16 SEER1, reducing annual cooling costs by 8-20%. This system suits mild climates or secondary spaces where cooling runs fewer hours annually. In hot climates with 1500+ cooling hours yearly, a higher SEER model saves $300-600 per year in electricity.
Can I install this myself or do I need a licensed tech? +
Professional installation is required to maintain the 10-year warranty and ensure proper refrigerant charging. DIY installation voids coverage. Hiring a licensed HVAC contractor costs $1200-2000 for labor but guarantees AHRI documentation and system optimization. The 7424266 AHRI certificate applies only to qualified installations.
Will this handle humid climates effectively? +
Single-stage cooling is a limiting factor in humid regions. The compressor runs full capacity then shuts off completely, limiting dehumidification cycles. Variable-speed blower helps somewhat, but cannot match two-stage or variable-capacity systems. Consider this unit suitable for dry climates or low-humidity seasons only. Humid climates benefit from 14+ SEER equipment with modulating compressors.
What are realistic operating costs compared to a 16 SEER system? +
In a 2000-hour annual cooling season, 13 SEER costs approximately $520 annually while 16 SEER costs $410, a $110 annual difference. Over the 10-year warranty period, you pay roughly $1100 more in electricity. This narrower gap makes sense only if upfront savings exceed $1500. If equipment prices are similar, buy the higher SEER unit instead.
Does the 10-year warranty cover refrigerant leaks or compressor failures? +
Yes, compressor failures and refrigerant leaks caused by manufacturing defects are covered for 10 years. Labor and refrigerant recharging are your responsibility. Leaks caused by improper brazing, vibration, or installation negligence are not covered. Maintenance records documenting annual filter changes strengthen warranty claims.
