// Bottom Line
This Goodman system delivers solid efficiency gains for homeowners upgrading from older equipment, with a 97% AFUE furnace and 16 SEER2 cooling. The $643 price point makes it accessible for budget-conscious contractors and DIY installers looking for proven, reliable hardware.

Review

Goodman's gas furnace and air conditioner combo addresses a real market need, homeowners tired of paying utility bills on equipment from the 2000s. At $643, this system sits in the sweet spot where efficiency upgrades become financially justifiable. The unit combines an 80,000 BTU furnace with a 29,000 BTU condenser, covering most residential applications. Online Supply positions this as a contractor-friendly option with straightforward specifications and broad compatibility.

The numbers tell a compelling story. The 97% AFUE furnace converts nearly all fuel to usable heat, a 10-15 point jump from typical 1995 equipment. Cooling efficiency reaches 16 SEER2, meaning significantly lower summer electric bills. The modulating burner stages reduce cycling losses, while the variable-speed ECM blower motor runs only as hard as needed. Maximum CFM reaches 1200, sufficient for homes up to 2500 square feet. The scroll compressor handles R410A refrigerant with proven longevity in residential applications.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency reduces heating costs significantly compared to 80s-era equipment
  • 16 SEER2 cooling rating qualifies for ENERGY STAR and many utility rebates
  • Modulating burner stages and variable-speed ECM blower motor for precise comfort control
  • Scroll compressor technology is durable and widely supported by service technicians
  • PVC exhaust compatibility simplifies venting in tight installations

Cons

  • Single-stage condenser limits part-load efficiency during mild weather operation
  • Spec discrepancy shows 2.5 ton in title but 3 ton in actual tonnage field, creating potential confusion
  • 71.5 dB noise level is moderately loud, noticeable in quiet neighborhoods during operation

Who Should Buy

Best For

Homeowners and contractors replacing 15-20 year old furnace and AC systems who want measurable efficiency gains without premium pricing. This system works well for mixed climates where both heating and cooling matter equally.

Consider Alternatives If

Anyone needing variable-capacity cooling for extreme climate zones or those prioritizing whisper-quiet operation should consider higher-end models with two-stage compressors.

Installation

Installation requires standard HVAC practices, 115V single-phase power, and a 17.1 to 25 amp breaker. The A-coil style pairs with most blower compartments, though upflow orientation limits placement options. Suction line insulation at 3/4 inch thickness comes standard. PVC exhaust flues simplify venting complexity. Technicians familiar with Goodman equipment will find minimal learning curve.

Warranty & Reliability

Goodman covers this system for 10 years following online registration, which is industry standard for mid-tier equipment. This protects against manufacturing defects but excludes wear items and labor. Real-world value depends heavily on completing registration promptly after installation.

Frequently Asked Questions

What's the actual tonnage, 2.5 or 3 tons? +
The specifications list 3 ton tonnage and 29,000 BTU cooling capacity. The 2.5 ton title appears to be a labeling error. Verify tonnage matches your home's load calculation before purchase to ensure proper sizing.
Can I install this myself if I have HVAC experience? +
Technically possible, but consider refrigerant handling laws. Many states require EPA 608 certification to work with R410A systems. Electrical connections demand 17.1-25 amp breaker sizing and proper grounding. Professional installation protects your warranty.
How much will this reduce my utility bills compared to a 1998 system? +
Expect 20-35% heating savings from the 97% AFUE furnace and 30-40% cooling savings from the 16 SEER2 rating. Actual savings depend on your climate, insulation, and usage patterns. High-efficiency upgrades pay back in 5-8 years for average homeowners.
Is this better than a Carrier or Lennox system at the same price? +
Goodman and Carrier are identical parent companies using shared platforms. This Goodman unit offers equivalent performance at lower cost. Lennox models typically cost 15-25% more while delivering similar efficiency ratings and comparable reliability.
What happens after the 10-year warranty expires? +
Coverage ends completely. Parts and labor become your responsibility. Scroll compressors typically last 15-20 years, so plan for potential replacement costs after year 10.
