// Bottom Line
This Goodman combo system excels for homeowners upgrading older furnace-AC pairs in tight spaces where horizontal installation is required. The 97% AFUE heating efficiency and 16 SEER cooling make it a solid mid-range choice for mixed climates, though the spec sheet shows a tonnage mismatch that requires verification before purchase.

Review

The Goodman CHPF3636B6 represents the brand's commitment to delivering efficient heating and cooling in a single horizontal package. At this price point, Goodman positions itself as the value-conscious alternative to premium brands like Lennox or Carrier, offering respectable efficiency ratings without the premium markup. This unit combines an 80,000 BTU gas furnace with a 24,000 BTU cooling component, designed primarily for retrofit installations where space constraints favor compact equipment placement.

Performance numbers tell an encouraging story for budget-conscious buyers. The 97% AFUE rating means heating efficiency that converts nearly all fuel to usable heat, while the 16 SEER cooling rating qualifies the unit for Energy Star recognition and many utility company rebates. The modulating burner varies output smoothly across its range, and the variable-speed ECM blower handles everything from 0 to 1200 CFM, allowing precise humidity control. At 71 dBA, noise levels remain acceptable for most residential applications, though this isn't whisper-quiet operation.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency significantly reduces heating costs in winter months
  • 16 SEER cooling efficiency qualifies for Energy Star and potential utility rebates
  • Modulating burner stages fine-tune heat output, improving comfort and reducing short-cycling
  • Variable-speed ECM blower motor adjusts airflow from 0 to 1200 CFM for better dehumidification
  • Two-stage scroll compressor provides quieter operation at 71 dBA under typical loads
  • PVC flue exhaust compatibility simplifies venting in new construction or retrofit applications

Cons

  • Specification sheet lists conflicting tonnage: title says 2 ton but specs show 3 ton cooling capacity, creating confusion about actual cooling capacity
  • Limited to 115V single-phase power means standard residential electrical service is required without upgrades
  • Horizontal configuration limits placement options in homes with basement or crawlspace installations

Who Should Buy

Best For

Homeowners in moderate climates replacing aging furnace-AC combinations who have horizontal space requirements and qualify for manufacturer rebates. Contractors installing retrofit systems in tight attic or mechanical room spaces where a compact, efficient combo unit avoids separate equipment procurement.

Consider Alternatives If

Buyers needing true 2-ton cooling capacity should clarify with the manufacturer before purchasing, as the spec sheet contains conflicting tonnage information.

Installation

This horizontal unit installs in tight spaces where downflow/horizontal airflow is feasible, such as attics or narrow mechanical rooms. The 21.125 inch height and 26 inch depth fit standard 24-inch return-air plenums. Connection requires 3/8 inch liquid lines and 7/8 inch suction lines with sweat-type valves. PVC flue venting simplifies installation compared to metal ductwork. Standard 115V single-phase power keeps electrical upgrades minimal.

Warranty & Reliability

Goodman provides a solid 10-year parts warranty with online registration required. This covers defects in materials and workmanship, though labor and refrigerant are typically excluded. Registration is straightforward and essential to activate the full coverage period. For comparison, premium brands sometimes offer longer terms, but 10 years aligns well with mid-tier equipment life expectations.

Frequently Asked Questions

What's the actual cooling capacity, 2 tons or 3 tons? +
The product title claims 2 tons, but specifications list 3 ton tonnage with 24,000 BTU cooling capacity. This mismatch is concerning because 24,000 BTU equals 2 tons exactly. Contact the manufacturer before purchasing to confirm which rating is correct for your home's cooling needs.
Can this unit work with my existing ductwork? +
Yes, if your current system uses standard 3/8 inch liquid lines and 7/8 inch suction lines with sweat connections. The horizontal configuration requires downflow or horizontal airflow compatibility. Have a technician verify your ductwork sizing matches the 1200 CFM maximum airflow before installation begins.
How much will this save on heating bills compared to older furnaces? +
The 97% AFUE rating means roughly 3-5% annual heating cost savings versus a 94% AFUE unit, depending on fuel costs. Against older 80% AFUE furnaces, expect 15-20% heating savings. Actual results vary by climate, thermostat settings, and home insulation quality.
How does 16 SEER compare to newer SEER2 ratings? +
16 SEER (old rating system) roughly equals 12-13 SEER2 (new standard adopted 2023). Newer units might advertise higher SEER2 numbers, but direct comparison is difficult. Check AHRI certificate 7424270 for verified performance data.
Do I need a service contract or extended warranty? +
The 10-year warranty covers defects well. Extended service contracts are optional but worth considering if you lack HVAC maintenance knowledge. Budget 1-2 annual service calls to keep performance optimal and warranty valid.
