// Bottom Line
This 2-ton Goodman system works best for homeowners replacing an older single-stage furnace who want measurable energy savings without premium pricing. The 97% AFUE heating efficiency and modulating burner make it a solid mid-range choice for moderate climates where heating dominates usage.

Review

Goodman's horizontal gas furnace and air conditioning system sits comfortably in the mid-market segment, targeting contractors and homeowners who want measurable efficiency improvements without flagship pricing. The 97% AFUE rating positions this unit ahead of older baseline equipment, while the 16 SEER cooling efficiency qualifies for Energy Star recognition. Goodman remains a trusted brand for cost-conscious buyers, though this particular model introduces some specification inconsistencies worth examining before purchase.

The furnace delivers 60,000 BTU heating output with a modulating burner that adjusts flame intensity rather than simple on-off cycling, improving comfort and reducing short-cycling waste. Cooling capacity measures 23,600 BTU with a scroll compressor running at single-stage compression. The variable-speed ECM blower reaches 1,200 CFM maximum and adapts to actual demand, using substantially less energy than traditional fixed-speed motors. These specifications justify the mid-tier pricing, though the 71.5 dB operating noise runs above premium alternatives.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency cuts heating costs significantly compared to older 80-85% models
  • Modulating burner stages optimize comfort by varying heat output rather than cycling on-off
  • Variable-speed ECM blower distributes air evenly and uses less electricity than fixed-speed motors
  • 10-year warranty with online registration provides reasonable protection for mid-tier equipment
  • 16 SEER cooling efficiency earns Energy Star certification for A/C performance
  • Plastic PVC exhaust flue reduces installation complexity versus metal ductwork

Cons

  • Specification sheet lists conflicting tonnage (title says 2 ton but specs show 3 ton) creating confusion about actual capacity
  • 71.5 dB noise level runs louder than premium brands, noticeable in quiet homes or bedrooms nearby
  • SKU LS38343850 replaces older GSX16S241 model, limiting upgrade paths if you need exact cross-compatibility
  • Single-stage condenser for cooling lacks the modulation luxury of the heating side

Who Should Buy

Best For

Homeowners replacing a 15-20 year old furnace in moderate heating climates who prioritize efficiency gains and lower utility bills. This system makes sense for those who want better performance than budget models but don't need premium features like variable capacity compressors.

Consider Alternatives If

Anyone in harsh northern climates needing maximum heating output should avoid the tonnage confusion here, and buyers wanting whisper-quiet operation should look at units rated below 70 dB.

Installation

Installation requires standard 115V single-phase 60Hz power with a 12.4 to 20 amp breaker. Refrigerant line sizes measure 3/8 inch for liquid and 3/4 inch for suction, with 3/4 inch insulation thickness recommended. The horizontal A-coil configuration suits attic or closet placement with 50 feet of suction line included. PVC exhaust flue compatibility simplifies venting compared to metal alternatives, reducing labor costs and complexity.

Warranty & Reliability

Goodman provides 10 years of coverage when you register the unit online, a reasonable protection span for mid-tier HVAC equipment. Registration is straightforward through Goodman's website and typically completes within minutes. This warranty covers defects in materials and workmanship but excludes wear items and installation errors, so keep your receipt and follow startup procedures carefully.

Frequently Asked Questions

Why does the product title say 2 ton but the specs list 3 ton capacity? +
This discrepancy appears to be a data entry error from the supplier. The cooling BTU of 23,600 aligns with 2-ton capacity (24,000 BTU per ton), suggesting the 3-ton spec is incorrect. Contact Online Supply before purchasing to confirm actual tonnage matches your existing ductwork and system design.
Can this furnace use both R410A and R22 refrigerant? +
No. While the spec sheet mentions both, modern units like this use R410A exclusively. R22 is being phased out. Confirm refrigerant type with your HVAC contractor before installation, as mixing refrigerants destroys the compressor and voids warranty coverage.
How much money will I save on heating costs compared to my old furnace? +
A 97% AFUE unit recovers 97 cents of heat energy per dollar spent on fuel, versus 80% AFUE older models that waste 20 cents per dollar. On a typical 5,000 heating degree day climate spending $1,200 annually, you'd save roughly 17% or about $200-250 per year depending on gas prices and usage patterns.
Is this system better than a high-efficiency heat pump? +
Heat pumps excel in mild climates but struggle below 40°F, requiring expensive electric backup heat in cold regions. This furnace performs better in harsh winters and costs less upfront than quality heat pump systems. Choose based on your local climate, not brand alone.
Do I need to register the warranty immediately? +
Yes. Online registration activates the 10-year coverage. Without it, you receive limited warranty protection. Register within 30 days of installation through Goodman's website using your invoice and equipment serial number.
