Review
Goodman's 3.5-ton upflow system represents a practical middle ground in residential HVAC. The 80,000 BTU furnace and 42,000 BTU cooling capacity target homes around 1,500-2,000 square feet. This configuration ships as AHRI certified unit 7368835, meaning components work together without field matching. The 96% AFUE furnace and 15 SEER air conditioner both carry Energy Star badges, qualifying many installations for utility rebates. Contractors appreciate Goodman's straightforward design and parts availability.
The furnace delivers efficiency through modulating two-stage burners and a variable-speed ECM blower running up to 1,600 CFM. At 96% AFUE, approximately 96 cents of every fuel dollar converts to usable heat, a significant jump from 80% baseline units. The air conditioning side uses a scroll compressor with R410A or R22 refrigerant options. Single-stage condenser operation means cooling runs full capacity without modulation, slightly limiting part-load efficiency. The 208/230V single-phase 60Hz electrical requirement suits standard residential service. Measured noise runs 73 dBA, comparable to mid-tier equipment but noticeable during operation.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% models
- 15 SEER cooling efficiency qualifies for Energy Star and federal incentives in many regions
- Variable-speed ECM blower motor delivers quieter operation and better air distribution than single-speed units
- Two-stage burner provides modulating heat output for improved comfort and fuel economy
- Plastic PVC exhaust flue simplifies installation and reduces venting costs versus metal ducting
- 10-year warranty with online registration offers solid protection for residential applications
Cons
- 73 dBA noise level runs slightly louder than premium competitors, noticeable in adjacent rooms
- Single-stage condenser means air conditioning runs at full capacity, reducing part-load efficiency benefits
- 5-ton condenser paired with 80,000 BTU furnace creates capacity mismatch for some climate zones
- SEER1 rating of 16 reflects lab conditions, real-world performance typically 10-15% lower
Who Should Buy
Best For
Contractors installing split systems in moderate climates where balanced heating and cooling matter equally. Homeowners replacing older equipment who value reliability and energy savings without mid-tier pricing premiums.
Consider Alternatives If
Anyone needing primarily heating in cold climates should specify higher BTU furnaces, or those seeking maximum efficiency should look at two-stage condensers and scroll compressors with variable staging.
Installation
Installation favors experienced HVAC technicians familiar with split-system configurations. The upflow/downflow design works with right-side flue positioning, requiring clearance planning. Plastic PVC exhaust simplifies venting versus traditional metal flues. Refrigerant lines measure 3/8 inch liquid and 1 1/8 inch suction, requiring proper brazing and evacuation. The 50-foot line set standard length accommodates most residential layouts. Electrical service demands breakers between 23.5 and 40 amps. AHRI certification reduces field matching complexity.
Warranty & Reliability
Goodman backs this system with 10 years of parts coverage upon online registration. The warranty covers manufacturing defects in the furnace, condenser, and coil. Labor costs fall on the installing contractor or homeowner, typical for this price category. Registration extends warranty protection and simplifies claims processing. Evaporator coil carries separate coverage outlined in included documentation.
