Review
The Goodman 2-ton horizontal system occupies practical middle ground in residential HVAC. This gas furnace and air conditioner pairing delivers 40,000 BTU heating capacity and 23,600 BTU cooling across the same footprint, making it suitable for homes under 2,500 square feet. Goodman maintains solid reputation among contractors for straightforward serviceability, and this SKU LS38343850 replaces the older GSX16S241 with measurable efficiency gains. The horizontal configuration fits tight attic spaces or crawlspaces where vertical clearance limits installation options.
Efficiency numbers tell the real story here. The furnace achieves 96% AFUE, meaning nearly every gas dollar converts to heat instead of escaping up the flue. The air conditioning side delivers 16 SEER2 performance with ENERGY STAR certification, qualifying homeowners for federal tax credits up to $2,000 and utility rebates varying by region. Variable-speed ECM blower technology maxes out at 1200 CFM, automatically throttling down during mild weather to reduce cycling losses. Combined annual savings versus baseline 80% AFUE units typically reach 15-20% on heating costs.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means minimal heating fuel waste, translating to 10-15% lower winter bills than 80% units
- 16 SEER2 air conditioner rating (ENERGY STAR certified) qualifies for federal rebates and utility incentives in most states
- Variable-speed ECM blower motor adjusts airflow to 1200 CFM maximum, reducing noise and improving comfort consistency
- Scroll compressor handles 23,600 cooling BTU reliably with fewer moving parts than reciprocating designs
- 10-year warranty with online registration covers parts, providing confidence for 2-3 replacement cycles
Cons
- Single-stage compressor cycles on and off rather than modulating, wasting energy during partial-load conditions
- 3-ton tonnage mismatch with advertised 2-ton capacity creates confusion and potential oversizing issues
- Plastic/PVC exhaust flue requirement limits installation flexibility compared to metal alternatives
- 71.5 dB noise level at full capacity rivals older window units, noticeable in bedrooms during summer
Who Should Buy
Best For
Homeowners upgrading from 80-82% AFUE furnaces in homes up to 2,500 square feet will see tangible heating cost reductions. Contractors balancing efficiency demands with budget constraints on mid-range residential replacements will appreciate the ENERGY STAR qualification without premium pricing.
Consider Alternatives If
Skip this unit if you need whisper-quiet operation, require variable-capacity compressor modulation, or live in climates with extreme seasonal imbalance where one function dominates usage patterns.
Installation
Horizontal orientation requires mounting on platforms in attics or crawlspaces with minimum 26 inches depth clearance. The 22-pound weight demands two-person handling through access points. Lineset connections use industry-standard 3/8-inch liquid and 3/4-inch suction lines with 50 feet of insulation-wrapped suction line included. Electrical demand stays modest at 115V single-phase, requiring 12.4 to 20 amp breaker sizing. PVC exhaust flue installation demands proper slope and condensate management.
Warranty & Reliability
Ten-year parts warranty activates through online registration, covering compressor, blower motor, and heat exchanger defects. This length matches industry standard for mid-tier equipment. Coverage excludes normal wear, refrigerant, and labor costs. Registration process takes five minutes online and must occur within 30 days of installation to activate full term.
