Review
Goodman's 3-ton combined gas furnace and air conditioning system represents a practical middle ground in residential HVAC equipment. This upflow configuration delivers 80,000 BTU heating capacity paired with 36,000 BTU cooling, addressing the core comfort needs of typical 2,000 to 2,500 square foot homes. Online Supply's SKU LS38343830 targets cost-conscious contractors and homeowners seeking factory-backed reliability without premium pricing.
The furnace achieves 80% AFUE efficiency through its two-stage burner design, reducing gas consumption during partial-load heating. The air conditioner reaches 14 SEER using a scroll compressor and R410A refrigerant, translating to lower summer electricity usage. High-efficiency multi-speed blower motor delivers up to 2000 CFM, improving airflow consistency. At 73 dBA, noise levels run moderate, noticeable but not intrusive compared to older single-speed systems.
Pros & Cons
Pros
- Two-stage burner with 80,000 BTU heating output provides responsive comfort control during winter months
- 14 SEER cooling efficiency meets Energy Star thresholds, reducing summer energy bills compared to older units
- High-efficiency multi-speed blower motor with 2000 CFM maximum airflow optimizes temperature distribution
- Compact upflow design fits standard equipment closets, cabinets, and basement installations
- 10-year warranty with online registration offers reasonable protection against manufacturer defects
Cons
- 80% AFUE is baseline efficiency, not premium, missing high-efficiency gas furnace advantages above 95% AFUE
- Single-stage condenser limits cooling modulation on mild days, running full capacity when partial capacity suffices
- 73 dBA noise level is moderately loud, noticeable during operation especially at night
Who Should Buy
Best For
Budget-conscious homeowners in moderate climates replacing 15+ year old systems who value upfront savings over premium efficiency ratings. Contractors handling standard residential replacements where clients want proven Goodman reliability without spending extra on high-efficiency models.
Consider Alternatives If
Homeowners in extreme heat regions, those wanting Energy Star certification, or buyers seeking premium long-term efficiency where higher SEER and AFUE ratings justify increased investment.
Installation
Standard upflow installation fits most utility closets and basement mechanical rooms with its compact 30-inch height, 21-inch width, and 21-inch depth dimensions. Unit requires 208/230v single-phase 60 Hz electrical service with 18.7 to 30 amp breaker capacity. Metal exhaust flue connection needed for furnace venting.
