Review
The Goodman 3.5 ton gas furnace and air conditioning system positions itself as a practical workhorse for homes requiring both robust heating and cooling. Listed at $415, this unit targets contractors and homeowners tired of paying premium prices for basic efficiency upgrades. Goodman's reputation for reliability combined with solid efficiency ratings makes this an accessible entry point for system replacements without sacrificing performance or warranty coverage.
The furnace delivers 120,000 BTU heating output at 96% AFUE, meaning 96 cents of every dollar spent on gas converts to usable heat. The air conditioning side produces 34,800 BTU cooling with a 16 SEER2 rating, outperforming the advertised 15 SEER specification. The multi-speed ECM blower motor tops out at 2,000 CFM, automatically modulating airflow across heating and cooling cycles. Operating at 73.5 dB, noise levels are moderate but noticeable in quiet spaces.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means lower heating bills, especially valuable in northern climates with extended winter seasons
- 16 SEER2 cooling efficiency exceeds the 15 SEER specification, delivering stronger than advertised air conditioning performance
- Multi-speed ECM blower motor adjusts to heating and cooling needs, reducing runtime and energy consumption compared to single-speed units
- Two-stage burner allows partial heating during mild days, avoiding short-cycling and improving comfort
- 3.5 ton capacity handles heating and cooling across mid-size homes with single upflow configuration
Cons
- 73.5 dB sound level is moderately loud, noticeable during operation and potentially disruptive in quiet neighborhoods
- Single-stage compressor means the air conditioner runs at full capacity regardless of cooling demand, less efficient on mild days than two-stage models
- Requires PVC exhaust flue installation specific to this model, limiting retrofit flexibility in older homes with masonry chimneys
Who Should Buy
Best For
Homeowners in cold climates upgrading older furnaces will see immediate heating cost reductions with 96% AFUE. Contractors looking to offer high-efficiency systems at competitive pricing will appreciate the value-to-performance ratio.
Consider Alternatives If
Buyers in hot climates needing maximum cooling efficiency should consider two-stage compressor units, and those with masonry chimneys cannot use the PVC-only flue requirement.
Installation
Installation requires 115V single-phase 60Hz electrical service with breaker capacity between 18.7 and 30 amps, readily available in most homes. The upflow configuration suits standard installations in basements or utility closets. Critically, this unit mandates PVC or plastic exhaust flue piping, eliminating compatibility with traditional masonry chimneys. Professional installation is strongly recommended to ensure proper refrigerant charging and gas line safety.
Warranty & Reliability
The 10-year parts warranty activates upon online registration, providing solid coverage for the compressor, blower motor, and heat exchanger. This warranty level matches mid-tier Goodman offerings. Registration is straightforward and extends peace of mind for the system's most expensive components, though homeowners must complete the registration process to activate coverage.
