Review
This Goodman gas furnace and air conditioning system represents a solid mid-to-premium efficiency option for homeowners upgrading aging HVAC equipment. The combination of 97% AFUE heating and 18 SEER2 cooling positions it as an ENERGY STAR qualified unit that balances performance with reasonable cost. Online Supply offers this downflow-configured system with a rebate incentive, making it more accessible than some competing brands at equivalent efficiency tiers.
The furnace delivers 100,000 BTU of heating output with a modulating burner that adjusts flame intensity based on demand, improving comfort during mild days. The air conditioning side provides 35,000 BTU of cooling capacity through a two-stage scroll compressor running on R410A refrigerant. The variable-speed ECM blower motor adjusts between 0 and 2000 CFM, allowing the system to maintain consistent air delivery without excessive cycling or noise at 71 dB.
Pros & Cons
Pros
- 97% AFUE furnace efficiency minimizes heating costs, translating to roughly 3 cents per 100,000 BTU of heat delivered
- 18 SEER2 rating on cooling side exceeds ENERGY STAR requirements, delivering superior summer efficiency
- Modulating burner stages adjust heating output automatically, reducing energy waste during partial-load operation
- Variable-speed ECM blower motor optimizes airflow between 0 and 2000 CFM, improving comfort and reducing runtime hours
- Two-stage scroll compressor handles peak cooling demand while running efficiently at part load
Cons
- Tonnage mismatch in specs lists both 3 ton and 5 ton, creating confusion about actual cooling capacity
- 71 dB noise level during operation may be noticeable in open-concept homes or quiet neighborhoods
- Downflow configuration limits installation flexibility, requiring basement or crawlspace placement
Who Should Buy
Best For
Homeowners in climates with substantial heating seasons, such as the Midwest or Northeast, will see the biggest payback from the 97% furnace efficiency. Contractors performing full system replacements where downflow orientation fits the home's layout will appreciate the modulating burner and variable-speed blower for customer comfort.
Consider Alternatives If
Skip this model if your home requires upflow configuration or if you're looking for a compact unit for tight installations. Renters and those planning to move within 5 years may not recover the efficiency gains quickly enough.
Installation
Downflow configuration requires the unit to sit above the main living space, typically in an attic, basement, or crawlspace with proper ductwork exiting downward. The 30-inch height, 24.5-inch width, and 21-inch depth fit standard mechanical closets in most homes. PVC exhaust venting is required for the furnace, and refrigerant line set comes with 3/4-inch suction line insulation rated for 50 feet of run.
Warranty & Reliability
Goodman backs this system with a 10-year parts warranty when registered online within 30 days of installation. This extends significantly beyond many competitors' standard 5-year coverage, offering genuine peace of mind for component failures. Labor and refrigerant are not covered, which is standard industry practice.
