// Bottom Line
This horizontal A-coil system works best for homeowners in moderate climates who need reliable heating and cooling without premium pricing. The 97% AFUE furnace and 18 SEER2 air conditioner combo delivers strong efficiency gains that will lower your utility bills while maintaining solid equipment durability.

Review

This Goodman horizontal A-coil system positions itself as a practical mid-market solution for homeowners seeking efficient heating and cooling without flagship pricing. The combination of a 97% AFUE gas furnace and 18 SEER2 air conditioner appeals to contractors managing budget-conscious replacement jobs. At the $89 price point, you're getting proven Goodman engineering in a configuration that fits many existing installations where horizontal mounting makes sense.

Performance specifications tell a solid story. The furnace delivers 80,000 BTU heating capacity with modulating burner stages that adjust precisely to your home's demand, reducing energy waste. The air conditioning side produces 35,000 BTU cooling at 18 SEER2 efficiency with a two-stage scroll compressor that runs intelligently at partial load. The variable-speed ECM blower motor maxes out at 1600 CFM and adapts continuously, keeping noise at 71 dB while optimizing comfort. Both components qualify for Energy Star status.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency translates to minimal heating energy waste and lower winter bills
  • 18 SEER2 rating on cooling side qualifies for Energy Star certification and many utility rebates
  • Modulating burner stages provide precise heating control and consistent comfort without cycling
  • Variable-speed ECM blower motor adjusts airflow to 1600 CFM maximum, reducing noise and improving efficiency
  • Two-stage scroll compressor runs efficiently at partial load, extending equipment lifespan
  • 10-year warranty with online registration gives reasonable protection for the price point

Cons

  • Product title claims 3 ton cooling but specs show 5 ton tonnage, creating confusing discrepancy
  • 80,000 BTU heating output is modest for cold climates, requiring larger systems in northern regions
  • 71 dB noise level is slightly above quieter competitors, noticeable in open floor plans
  • Requires plastic/PVC exhaust flue, limiting installation flexibility in some homes

Who Should Buy

Best For

Homeowners in temperate climates upgrading 20+ year old systems will appreciate the efficiency gains and modest price tag. Contractors installing budget-conscious replacement systems where heating demands are moderate to average will find solid value here.

Consider Alternatives If

Buyers in very cold climates needing 100,000+ BTU output should look at larger capacity models. Homeowners prioritizing whisper-quiet operation may want to compare units rated below 68 dB.

Installation

This horizontal configuration suits homes where basement or attic space is limited vertically but wide enough to accommodate the 50-inch length, 26-inch width, and 24.5-inch height. Connection requires standard 3/8 inch liquid and 7/8 inch suction lines with existing sweat valve fittings. The plastic/PVC exhaust flue requirement simplifies venting in most homes. Electrical demand runs 115V, 1-phase, 60Hz with a 21.3 to 35-amp breaker range.

Warranty & Reliability

Goodman backs this system with a 10-year warranty on parts, covering compressor and heat exchanger defects. Online registration is required to activate full coverage. This timeframe aligns with mid-tier equipment expectations. Coverage excludes wear items like capacitors and contactor switches, which are consumable components.

Frequently Asked Questions

Why does the title say 3 ton but specs list 5 ton tonnage? +
This appears to be a data entry error on the product page. Verify actual tonnage with the supplier before purchase. The 35,000 BTU cooling output suggests closer to 2.9 ton capacity. Request clarification on this discrepancy to ensure your ductwork and indoor coil are properly matched.
Can I install this system myself? +
Licensed HVAC technicians should handle refrigerant connections, ductwork integration, and gas line setup. Horizontal A-coil installation requires proper condensate drainage sloped away from the unit. Electrical work and ductwork sealing also demand professional expertise for warranty validity and safety compliance.
How much will utility bills drop with 97% AFUE and 18 SEER2? +
Compared to a 78% AFUE furnace and 10 SEER air conditioner from 2000, expect 15-25% annual heating and cooling savings depending on climate and usage patterns. Actual savings vary by local utility rates, insulation quality, and thermostat settings. Many homeowners recover equipment cost in 6-8 years.
Is this system better than a high-efficiency unit like Lennox or Carrier? +
This Goodman delivers comparable efficiency ratings at lower cost, though premium brands offer quieter operation and longer-term component durability. For budget-conscious buyers, Goodman provides reliable performance. For buyers prioritizing whisper-quiet operation or extended warranties, premium brands justify higher pricing.
What does the 10-year warranty actually cover? +
Parts coverage includes compressor, heat exchanger, and major components when registered online. Labor and wear items are excluded. Review the full warranty document before purchase to understand specific limitations and claim procedures.
