Review
Goodman's 2.5-ton gas furnace and air conditioner combo occupies the practical middle ground between budget and performance. This Online Supply SKU LS38783850 pairs an 80,000 BTU, two-stage furnace with an 80% AFUE rating against a 2.5-ton condenser rated at 16 SEER2 and 29,000 cooling BTU. Priced at $2,700, it appeals to contractors seeking straightforward, no-frills equipment and homeowners facing replacement costs without premium budgets. The Energy Star certification and 10-year warranty add modest credibility to what is fundamentally a dependable workhorse system.
Performance metrics show solid, if unspectacular, numbers. The furnace delivers heating via two-stage burner operation, reducing efficiency losses from constant on-off cycling. On cooling, the 16 SEER2 condenser with scroll compressor and single-stage operation provides efficient part-load performance in mild weather, though it lacks variable-capacity technology. The variable-speed blower motor on the heating side reduces runtime energy consumption by modulating airflow based on demand. Electrical specs are modest, requiring 17.1 to 25-amp service, making retrofit wiring straightforward in most homes. At 71.5 dB, noise levels are noticeable but acceptable for residential settings.
Pros & Cons
Pros
- 16 SEER2 cooling efficiency on the condenser, which significantly exceeds the 2.5-ton nameplate rating and provides measurable energy savings
- Variable speed blower motor optimizes comfort and reduces energy waste compared to single-speed alternatives
- Two-stage burner on the furnace allows for modulated heating, reducing short cycling and improving efficiency
- 80,000 BTU heating output handles full-load demands without auxiliary staging
- Dual fuel compatibility, accepting both natural gas and propane for installation flexibility
- Reasonable 30-pound condenser weight and compact 21 by 21 by 30-inch dimensions simplify rooftop or ground placement
Cons
- 80% AFUE is baseline efficiency, not premium; modern condensing furnaces reach 90% to 96% AFUE
- Single-stage compressor on cooling side limits part-load efficiency during mild weather operation
- 71.5 dB noise level is moderately loud, noticeable when the system cycles in quiet spaces
- Limited to 25-amp maximum breaker size, restricting power supply flexibility on some installations
- Spec sheet lists both 2.5 and 3.5 tonnage, creating confusion about actual cooling capacity
Who Should Buy
Best For
Budget-conscious homeowners and contractors who prioritize straightforward installation and reliable operation over cutting-edge efficiency ratings. This system suits replacement jobs in homes sized for 2.5 tons of cooling and 80,000 BTU heating, especially where natural gas is already piped and downtime must be minimized.
Consider Alternatives If
Buyers in high-efficiency markets like ENERGY STAR-focused regions or those seeking 90%+ AFUE furnaces and variable-capacity compressors should compare condensing units or inverter-driven systems elsewhere.
Installation
This upflow configuration uses a metal exhaust flue and accepts both natural gas and propane, streamlining installation flexibility. The A-coil design works with most standard air handlers, and suction and liquid lines are sized at 7/8 inch and 3/8 inch respectively. The compact 21 by 21 by 30-inch condenser footprint fits tight rooftop or ground pads. Refrigerant compatibility includes R410A or R22, though R410A is standard for new builds. Installation documentation is available via CAPF manuals, but field experience matters for proper staging and blower motor commissioning.
Warranty & Reliability
Goodman backs the unit with a 10-year parts warranty contingent on online registration. This is competitive for mid-range equipment but shorter than some 15-year offerings from competitors. The warranty covers compressor and component defects but typically excludes labor, meaning emergency service costs fall to the homeowner. Registration is straightforward and should be completed at purchase.
