Review
Goodman's modulating gas furnace and air conditioner combination targets efficiency-conscious homeowners seeking better comfort control than older equipment provides. This downflow configuration works in basements, crawlspaces, or utility closets where horizontal airflow suits the home's layout. The 97% AFUE rating and Energy Star certification signal solid engineering, while the two-stage condenser approach differentiates it from basic single-stage competitors. Online Supply distributes this unit under SKU LS38783850 with AHRI verification number 7424269.
The furnace delivers 60,000 BTU of heat using modulating burner technology, which gradually adjusts flame level rather than simply cycling on-off. The air conditioner produces 35,000 BTU cooling at 18 SEER1 efficiency through a two-stage scroll compressor and variable-speed ECM blower rated for 1,200 CFM maximum. This combination achieves better part-load performance than fixed-capacity systems, particularly in shoulder seasons when heating or cooling demand fluctuates hourly. Electrical requirements are moderate at 208-230V single-phase, requiring a 21.3 to 35 amp breaker.
Pros & Cons
Pros
- 97% AFUE furnace efficiency reduces heating costs substantially compared to standard 80-85% models
- Modulating burner adjusts output in real-time rather than cycling on-off, improving comfort and lowering utility bills
- Two-stage condenser with scroll compressor provides staged cooling, matching load requirements for better efficiency
- Variable-speed ECM blower motor runs quietly at 71 dBA and uses less energy than fixed-speed alternatives
- PVC exhaust compatibility simplifies venting in modern homes and enables condensing flue pipe installation
- Energy Star certified with 18 SEER1 cooling rating and 10-year warranty with online registration
Cons
- Spec sheet lists conflicting tonnage: header says 3 ton but specs show 5 ton cooling capacity, creating confusion during system sizing
- 60,000 BTU heating output limits this to smaller homes or mild-winter regions, insufficient for large properties in cold climates
- Electrical requirement of 208/230V single-phase may require panel upgrades in some installations, adding cost
Who Should Buy
Best For
Homeowners in moderate climates replacing aging furnaces want maximum heating efficiency without massive cooling capacity. This system suits homes under 2,000 square feet or those in regions where winter heating demands exceed summer cooling needs.
Consider Alternatives If
Contractors installing systems in homes larger than 2,500 square feet or in hot climates should source units with higher BTU ratings, as 60,000 BTU heating and 35,000 BTU cooling undersizes larger spaces.
Installation
Downflow design suits basements and utility closets with adequate clearance below the unit. PVC exhaust venting simplifies installation compared to metal flue pipes, reducing labor time. Technicians need 3/8-inch liquid line and 7/8-inch suction line connections with 3/4-inch insulation thickness specified. Proper airflow balance across the 1,200 CFM maximum requires competent ductwork sizing and sealing.
Warranty & Reliability
Goodman provides a 10-year parts warranty when owners complete online registration promptly after installation. This duration covers compressor, heat exchanger, and controls, offering reasonable peace-of-mind protection. Registration is essential, as non-registered units typically receive shorter coverage. Labor and service calls remain out-of-pocket expenses.
