// Bottom Line
This Goodman system excels for homeowners seeking reliable heating and cooling in moderate climates without premium pricing. The 96% AFUE heating efficiency and 16 SEER2 cooling make it ideal for contractors installing complete replacements where budget matters but efficiency can't be compromised.

Review

The 2-ton Goodman gas furnace and air conditioner system occupies solid middle ground in the residential HVAC market. This horizontal configuration suits homes where upflow or horizontal mounting works with existing ductwork layout. At 96% AFUE for heating and 16 SEER2 for cooling, it targets contractors and homeowners who prioritize documented efficiency without reaching premium product tiers. Online Supply's SKU LS38343850 replaces the GSX16S241, making upgrades straightforward for existing installations.

Performance specs tell a straightforward story. The furnace delivers 80,000 BTU of heating output using a two-stage burner that reduces runtime cycling and improves comfort control. Cooling capacity reaches 23,600 BTU, appropriate for moderate climate zones and smaller homes or additions. The multi-speed ECM blower motor adjusts CFM up to 1200, matching seasonal demand. Operating at 71.5 dB keeps noise reasonable though not whisper-quiet. The scroll compressor and R410A refrigerant compatibility meet current environmental standards.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency means lower winter heating costs compared to standard 80-90% models
  • 16 SEER2 cooling rating delivers solid air conditioning performance for 2-ton applications
  • Multi-speed ECM blower motor adapts to airflow demands, improving comfort and efficiency
  • Two-stage burner provides better temperature control and quieter operation at part load
  • Lifetime heat exchanger warranty plus 10-year parts coverage with registration offers genuine protection

Cons

  • Single-stage compressor limits efficiency gains compared to variable-capacity competitors
  • 71.5 dB noise level is moderate, not ideal for noise-sensitive installations
  • Requires PVC/plastic exhaust flue, limiting some retrofit applications with older metal ductwork

Who Should Buy

Best For

Homeowners replacing aging furnace-AC combos who want measurable efficiency gains without boutique pricing. Contractors handling moderate-capacity installs where the 80,000 BTU heating and 23,600 BTU cooling satisfy load calculations.

Consider Alternatives If

Anyone needing variable-capacity cooling or seeking the quietest possible operation should consider higher-tier Goodman or competitor options.

Installation

Installation requires standard HVAC practices with some considerations. The horizontal A-coil configuration needs proper drainage in attic or crawlspace mounting. Suction and liquid lines measure 3/4-inch and 3/8-inch respectively, using 3/4-inch insulation thickness. PVC flue venting requirement simplifies exhaust routing in most homes but may complicate retrofits. Electrical requirements stay modest at 115V single-phase 60 Hz with 12.4 to 20-amp breaker sizing, fitting standard residential panels without upgrade costs.

Warranty & Reliability

Coverage includes a lifetime heat exchanger warranty, 10-year unit replacement protection, and 10-year parts warranty upon online registration. This structure rewards engaged homeowners while protecting against premature compressor or motor failure. The heat exchanger lifetime coverage reflects Goodman's confidence in furnace reliability. Registration is straightforward and unlocks full protection, making warranty value accessible to informed buyers.

Frequently Asked Questions

How does 96% AFUE compare to my current furnace efficiency? +
Standard older furnaces operate at 78-85% AFUE. At 96%, this Goodman model converts 96 cents of every fuel dollar into usable heat, with only 4 cents lost up the flue. For a 60,000 annual heating degree-day climate, upgrading from 80% AFUE saves roughly $200-300 yearly on natural gas.
Can I install this in an existing 3-ton system location? +
Physically, yes, dimensions are 34.5 inches high by 17.5 inches wide by 28.75 inches deep. However, verify your cooling load actually requires only 2 tons (23,600 BTU). Oversizing or undersizing creates efficiency problems. Have a contractor perform a proper load calculation before replacing equipment.
Is 16 SEER2 good cooling efficiency for this tonnage? +
Yes. SEER2 testing uses realistic temperatures matching actual use. At 16 SEER2, this system ranks solid mid-tier cooling efficiency. Premium units reach 20-22 SEER2 but cost significantly more. For moderate climates or homes without extreme cooling demands, 16 SEER2 delivers genuine energy savings without premium pricing.
What separates this from cheaper Goodman alternatives? +
Lower-cost Goodman models use single-stage burners and 14-15 SEER2 cooling. This unit's two-stage burner and 16 SEER2 rating improve temperature control and cooling efficiency measurably. The ECM blower is standard here but absent on entry-level models, making monthly electricity use noticeably lower.
Does online registration really matter for warranty? +
Yes. Full 10-year parts coverage requires registration. Without it, coverage drops significantly. Registration takes five minutes online and protects you if a compressor or motor fails within decade. Goodman enforces this consistently.
