Review
The Goodman 3-ton two-stage system represents a solid mid-market option for homeowners seeking an integrated furnace and air conditioning solution. This downflow configuration works well in basements or attics where horizontal space is limited. The unit combines proven Goodman reliability with modern efficiency ratings, bridging budget-conscious buyers and those wanting measurable utility savings. SKU LS38783850 carries a 10-year warranty and ENERGY STAR certification, positioning it competitively against Bryant and Lennox alternatives in the same price range.
Performance metrics are where this system shines. The furnace delivers 80,000 BTU heating output at 96% AFUE, meaning 96 cents of every heating dollar goes directly to warming your home. Cooling capacity reaches 35,000 BTU with 18 SEER2 efficiency, powered by a scroll compressor and variable-speed ECM blower handling up to 1,600 CFM. Two-stage operation in both components reduces excessive cycling, improving comfort during mild weather and cutting compressor runtime by approximately 40% compared to single-stage competitors.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs by 15-20% compared to standard 80% AFUE units
- 18 SEER2 cooling efficiency qualifies for ENERGY STAR certification and potential utility rebates
- Two-stage operation in both furnace and condenser minimizes runtime noise and improves comfort
- Variable-speed ECM blower motor adjusts airflow intelligently, reducing energy consumption by up to 25%
- PVC exhaust compatibility simplifies venting in retrofit applications without special ductwork
Cons
- Spec sheet lists conflicting tonnage ratings (3 ton vs 5 ton), creating confusion about actual cooling capacity
- 71 dB noise level is moderately loud for a two-stage system, particularly during compressor operation
- R410A refrigerant is being phased out, potentially affecting future service availability after 2025
Who Should Buy
Best For
Homeowners in moderate climates upgrading from aging single-stage systems who value balanced heating and cooling performance. This system suits properties where gas heating is preferred and energy bills are a concern.
Consider Alternatives If
Anyone in consistently hot climates needing primarily cooling capacity should consider a dedicated high-tonnage air conditioner, and those seeking the newest R32 refrigerant should wait for updated Goodman models.
Installation
This downflow unit requires 208/230V single-phase 60 Hz electrical service with breaker capacity between 21.3 and 35 amps. PVC exhaust venting simplifies installation in older homes avoiding masonry flues. The unit weighs 30 pounds and measures 30 inches tall by 24.5 inches wide by 21 inches deep, fitting standard basement equipment closets. Refrigerant line sizing calls for 3/8-inch liquid and 7/8-inch suction lines with 3/4-inch insulation thickness.
Warranty & Reliability
Goodman backs this system with a 10-year parts warranty when registered online within 30 days of installation. Coverage includes the compressor, heat exchanger, and evaporator coil. Registration is straightforward through Goodman's website and extends beyond the standard 5-year non-registered warranty. This protection is competitive for the price point, though some premium brands offer 12-year coverage.
