Review
This Goodman gas furnace and air conditioner combination targets the mainstream replacement market where homeowners need both reliable heating and efficient cooling in a single system. At 3.5 tons cooling and 100,000 BTU heating capacity, it fits typical single-family homes across temperate and moderate climates. The combination of 96% AFUE furnace efficiency and 16 SEER2 cooling rating positions it competitively against major brands, and Energy Star certification signals compliance with current efficiency standards.
The furnace delivers impressive heating performance at 96% AFUE through a two-stage burner design that reduces energy waste during partial-load operation. Cooling performance reaches 42,000 BTU output with a scroll compressor and single-stage configuration. The variable-speed ECM blower motor adapts to heating and cooling demands, improving comfort and reducing runtime compared to fixed-speed alternatives. At 73 dB, operation is noticeable but not excessive for basement or utility room placement. Electrical requirements are straightforward, needing 23.5 to 40-amp service depending on installation conditions.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means 96 cents of every energy dollar heats your home, well above the 90% minimum and comparable to premium brands
- 16 SEER2 cooling efficiency with 42,000 BTU capacity delivers solid summer performance and Energy Star qualification
- Two-stage burner and variable-speed ECM blower motor reduce short-cycling and improve temperature consistency throughout your home
- Lifetime heat exchanger warranty protects against the most expensive failure point in gas furnaces
- PVC exhaust flue compatibility simplifies venting compared to traditional metal chimneys
Cons
- Single-stage cooling compressor means it runs at full capacity or off with no modulation, less efficient than two-stage alternatives
- 73 dB noise level is moderate-to-loud during operation, noticeable if installed in living spaces or near bedrooms
- 5-ton tonnage rating creates oversizing concerns if replacing a 3.5-ton system, potentially wasting energy and reducing dehumidification
Who Should Buy
Best For
Homeowners in mixed-heating-and-cooling climates upgrading from 10-year-old or older equipment who value both heating and cooling efficiency equally. This system makes sense for mid-range budgets where 96% AFUE and 16 SEER2 ratings deliver measurable monthly savings without the premium pricing of modulating compressor models.
Consider Alternatives If
Buyers in hot climates prioritizing cooling efficiency should look at two-stage or variable-capacity compressors instead, and anyone replacing existing 3.5-ton equipment should verify the 5-ton rating doesn't oversized their home.
Installation
Installation complexity is moderate for qualified HVAC technicians. The system accepts standard 3/8-inch liquid lines and 7/8-inch suction lines, with 1/2-inch insulation on the 1,128-inch suction line. PVC venting compatibility streamlines ductwork routing compared to metal alternatives. Variable-speed blower commissioning requires proper airflow verification to reach the 2,000 CFM maximum. A-coil configuration for upflow/horizontal operation demands careful condensate drain placement and support structure assessment.
Warranty & Reliability
Goodman backs the heat exchanger with lifetime coverage and parts with 10 years protection upon online registration. This dual-structure warranty prioritizes the component most likely to fail in gas furnaces, the heat exchanger, while providing solid decade-long parts coverage. Registration is mandatory to activate protection, and labor costs fall to homeowners. Coverage details should be reviewed on the warranty document before purchase.
