Review
Goodman's 3-ton gas furnace and air conditioner system sits solidly in the mid-range efficiency tier. With a 96% AFUE heating rating and ENERGY STAR certification, this unit targets cost-conscious homeowners who want meaningful savings without premium pricing. The downflow configuration makes it ideal for attic or basement installations common in existing homes. Online Supply offers this SKU LS38783850 with rebate eligibility, adding financial appeal to the upfront purchase.
Heating output hits 80,000 BTU with two-stage burners that modulate between high and low fire for responsive comfort. The variable-speed ECM blower maxes out at 1,600 CFM and runs quieter than single-speed motors due to reduced cycling. Cooling capacity measures 34,800 BTU with a scroll compressor, though the SEER1 rating of 16 suggests real-world performance closer to SEER2 14.5. Electrical draw requires a 30-amp breaker on 208/230V single-phase service, typical for most residential applications.
Pros & Cons
Pros
- 96% AFUE efficiency qualifies for ENERGY STAR and rebates, cutting heating costs noticeably year after year
- Variable-speed ECM blower motor runs quieter at 73.5 dBA and cycles more efficiently than fixed-speed alternatives
- Two-stage burner adapts to heating demand, reducing on-off cycling and wear on components
- PVC/plastic exhaust compatibility simplifies venting in attics and crawlspaces without expensive metal ductwork
- 10-year warranty with online registration provides solid peace of mind on parts and labor
Cons
- Spec sheet lists both 3-ton and 5-ton tonnage, creating confusion about actual cooling capacity (34,800 BTU suggests 2.9-ton, not 5-ton as stated)
- SEER1 rating of 16 is good but not exceptional; newer units hit 18-20 routinely
- Single-stage condenser limits cooling efficiency on mild days when full capacity isn't needed
Who Should Buy
Best For
Homeowners in moderate to cold climates replacing older furnaces, especially those with existing downflow or horizontal installations. This works well for combined heating and cooling upgrades where energy rebates matter and noise reduction from variable-speed operation is valued.
Consider Alternatives If
Buyers seeking maximum cooling efficiency in hot climates should look at dual-stage or modulating condenser units. Those in homes without PVC-compatible venting should explore units supporting standard metal flues.
Installation
This downflow unit needs PVC or plastic exhaust venting, eliminating expensive metal flue upgrades in many homes. The compact 30 by 21 by 21 inch cabinet fits standard equipment closets and attic spaces. Refrigerant lines (3/8 inch liquid, 7/8 inch suction) connect to compatible outdoor units up to 50 feet away. Professional installation ensures proper airflow, refrigerant charge, and gas line setup, though experienced HVAC techs report straightforward integration with existing ductwork.
Warranty & Reliability
Goodman backs this system with a 10-year parts and labor warranty upon online registration, one of the industry's stronger coverage periods. This protects against compressor failure, heat exchanger cracks, and component defects, though it excludes wear items like capacitors and contactor coils. Registration takes minutes online and unlocks the full protection, making it a worthwhile step at installation.
