// Bottom Line
This Goodman combo system targets budget-conscious homeowners and contractors who need reliable heating and cooling without premium pricing. The 92% AFUE and 14 SEER ratings deliver solid efficiency for mid-range comfort applications, making it practical for retrofit jobs and new builds in moderate climates.

Review

Goodman's gas furnace and air conditioner combo system lands squarely in the practical, mid-market segment where contractors and homeowners balance performance against budget. This upflow configuration handles both heating and cooling in one compact footprint, making it suitable for basement installations, utility closets, and retrofit applications. At this price point, the unit targets the replacement market where proven reliability matters more than cutting-edge efficiency. The 100,000 BTU heating capacity and 48,000 BTU cooling output position it for homes in moderate climate zones where seasonal demand fluctuates predictably.

The furnace delivers 92% AFUE, a solid 6 percentage points above the federal minimum 82% requirement, translating to meaningful gas savings over the system's 15 to 20 year lifespan. The 14 SEER cooling efficiency ranks adequately for 2024 standards, though it misses ENERGY STAR status. A multi-speed blower motor adds flexibility for temperature staging and humidity management. The scroll compressor and single-stage burner keep manufacturing costs reasonable but mean the system runs at full capacity rather than modulating for part-load conditions. Maximum airflow reaches 2,000 CFM, appropriate for residential delivery without excessive ductwork stress.

Pros & Cons

Pros

  • 92% AFUE furnace efficiency exceeds minimum federal standards by meaningful margin
  • 14 SEER cooling efficiency meets modern baseline expectations for split systems
  • Multi-speed blower motor allows better airflow control and comfort staging
  • Compact 21x21x30 inch footprint fits tight utility closets and basements
  • 10-year warranty with online registration provides reasonable coverage confidence
  • R410A refrigerant compatibility aligns with current EPA phase-out standards

Cons

  • 14 SEER rating is not ENERGY STAR certified, which some rebate programs require
  • Single-stage burner and single-stage compressor limit part-load efficiency and comfort in variable climates
  • 74 dB noise level is moderately loud for residential applications, especially during heating cycles
  • Requires 26.4 to 45 amp breaker, necessitating potentially expensive electrical upgrades in older homes
  • Spec discrepancy shows 4 ton unit but lists 5 ton tonnage, creating confusion on actual capacity

Who Should Buy

Best For

Contractors and homeowners replacing older systems want proven reliability without high-end pricing. This works well for moderate-climate regions where 92% furnace efficiency and single-stage cooling meet seasonal demands without constant cycling.

Consider Alternatives If

Skip this if you need ENERGY STAR certification for rebates, require variable-capacity comfort in hot-humid climates, or prioritize quiet operation in noise-sensitive settings.

Installation

Installation requires 208/230 volt single-phase power with a 26.4 to 45 amp breaker, potentially demanding electrical panel upgrades in older homes. The upflow configuration fits standard utility closets. PVC plastic exhaust flue works with modern venting standards. Standard refrigerant lines measure 3/8 inch liquid and 7/8 inch suction with 3/8 inch insulation thickness. This installation complexity sits in the moderate range, suitable for licensed HVAC technicians but not DIY projects.

Warranty & Reliability

The 10-year parts warranty requires online registration to activate. This coverage protects against compressor failure, heat exchanger cracks, and component defects common in early system life. Registration typically takes five minutes and extends your protection window meaningfully. Goodman's warranty stands solid in the mid-tier market, though premium brands sometimes offer 12-year coverage.

Frequently Asked Questions

What's the actual tonnage, and why does the spec show both 4 ton and 5 ton? +
The title states 4 ton, but the spec sheet lists 5 ton tonnage. This discrepancy suggests either a data entry error or a unit configured from different component batches. Contact Online Supply before purchase to confirm which rating applies to your SKU. Tonnage affects which sized ducts and air handlers you can pair with this system.
Can I upgrade the refrigerant from R22 to R410A? +
No, refrigerant type is set during manufacturing. The spec shows compatibility with both R22 and R410A depending on your model batch. Confirm refrigerant type at purchase since R22 is being phased out and costs more. R410A systems offer better long-term availability and regulatory alignment.
How does 92% AFUE compare to high-efficiency furnaces? +
92% AFUE is mid-range. Premium condensing furnaces reach 95 to 98% AFUE, saving approximately 3 to 6 percent more on heating costs annually. The 92% unit suits moderate climates well, but cold-climate homeowners heating six months yearly should consider high-efficiency models for faster payback on equipment costs.
Is 14 SEER competitive with other four-ton systems? +
14 SEER meets current baseline standards but trails premium variable-capacity units rated 18 to 21 SEER. For moderate climates with mild summers, 14 SEER costs less upfront and performs adequately. Hot-humid regions benefit more from higher SEER ratings that reduce cycling and humidity struggles.
Does the 10-year warranty cover labor and refrigerant? +
The 10-year limited warranty typically covers parts only. Labor and refrigerant charge usually require separate service agreements. Review the detailed warranty document before purchase to confirm coverage scope and any exclusions applying to your situation.
