// Bottom Line
This Goodman system excels for homeowners in moderate climates wanting high-efficiency heating and cooling without premium pricing. The 97% AFUE furnace and 18 SEER2 condenser deliver measurable energy savings, especially in homes with variable weather patterns.

Review

Goodman's combined gas furnace and air conditioner system targets efficiency-conscious homeowners seeking reliable performance without luxury pricing. The 4-ton unit pairs a 100,000 BTU furnace with a 47,000 BTU cooling capacity in an upflow A-coil configuration. With 97% AFUE and 18 SEER2 ratings, this system positions itself as a solid mid-tier choice for contractors and homeowners evaluating system replacements in moderate climates.

The furnace delivers excellent heating efficiency at 97% AFUE, meaning nearly every dollar of gas converts to usable heat. The cooling side employs a two-stage scroll compressor and runs at 72 dBA, producing noticeably quieter operation than single-stage competitors. Variable-speed ECM blower technology adjusts airflow between 0-2000 CFM, reducing short-cycling and improving humidity control. R410A refrigerant and PVC exhaust compatibility simplify installation in most residential applications.

Pros & Cons

Pros

  • 97% AFUE rating minimizes heating fuel waste, saving approximately 15-20% annually compared to 80% AFUE units
  • 18 SEER2 condenser with two-stage scroll compressor handles variable loads efficiently and reduces runtime noise at 72 dBA
  • Modulating burner adjusts heat output in real time, preventing energy waste during mild days
  • Variable-speed ECM blower motor runs quietly and distributes air evenly through 2000 CFM capacity
  • ENERGY STAR certified with 10-year comprehensive warranty upon online registration

Cons

  • Spec sheet shows 47,000 cooling BTU, which is below the stated 4-ton capacity (48,000 BTU), creating a minor tonnage mismatch
  • Two-stage compressor may not justify cost premium in very cold climates where heating dominates
  • Requires 115V single-phase power with 29.3 to 50-amp breaker, standard but worth verifying in older homes

Who Should Buy

Best For

Homeowners in temperate regions replacing 10-20 year old systems and concerned about utility bills will see the strongest ROI. Contractors installing complete systems in new construction or full replacements benefit from the ENERGY STAR rebates and straightforward installation.

Consider Alternatives If

Homeowners in extremely cold climates should explore modulating gas furnaces with higher BTU output, and those with tight budgets should compare this against 16 SEER2 models that cost significantly less.

Installation

This system requires standard upflow installation with right-side flue exit for PVC exhaust venting. Electrically, it needs 115V single-phase 60Hz service with breaker capacity between 29.3 and 50 amps, accommodating most residential panels. The 21-inch width and depth fit standard utility closets. Valve connections are sweat type, requiring moderate soldering skill or professional HVAC installation.

Warranty & Reliability

Goodman provides 10-year comprehensive coverage when registered online at purchase, covering parts and labor on the furnace and condenser. This goes beyond the industry standard 5-year parts-only warranty from many competitors. Extended service plan options are available through dealers for systems over 10 years.

Frequently Asked Questions

Why does the spec sheet show 47,000 BTU cooling when this is marketed as a 4-ton system? +
Standard 4-ton capacity equals 48,000 BTU. The 47,000 BTU rating likely reflects real-world conditions under AHRI testing. This 2% variance is negligible for residential comfort but worth confirming with your installer before purchase.
What electrical upgrades are needed for installation? +
Most homes have adequate 115V single-phase service. Verify your breaker panel supports 29.3 to 50-amp capacity. Older homes with 60-amp total service may need panel upgrades, which a licensed electrician should assess before ordering.
How much will this system reduce my annual heating and cooling costs? +
At 97% AFUE and 18 SEER2, expect 15-20% savings over 80% AFUE systems in moderate climates. Actual savings depend on local utility rates, insulation, and usage patterns. Annual heating savings alone typically range $200-400 in temperate regions.
Should I choose this over a 16 SEER2 system at a lower price point? +
The 18 SEER2 upgrade costs $800-1200 more but recovers that premium in 4-6 years through lower electric bills. Choose 16 SEER2 if budget is tight or heating dominates your climate. Choose 18 SEER2 if you plan to stay 10+ years.
Does the 10-year warranty cover everything? +
Online registration unlocks comprehensive coverage on parts and labor. Refrigerant, labor, and transportation are typically covered. Exclusions apply for improper installation, maintenance neglect, or electrical issues. Review warranty documents before installation.
