Review
The Goodman 3 Ton Gas Furnace and Air Conditioner System occupies the practical middle ground of residential HVAC equipment. At $2,053, it positions itself as an accessible upgrade for homeowners replacing aging systems without premium efficiency expectations. This upflow unit combines straightforward Goodman engineering with Energy Star certification, making it a reliable choice for contractors and DIY-minded owners alike.
The system delivers 34,800 BTU cooling with an impressive 16 SEER2 rating and 80,000 BTU heating at 80% AFUE efficiency. The scroll compressor handles single-stage cooling, while the furnace features two-stage burners for nuanced heating control. Variable-speed blower technology reaching 2,000 CFM distributes conditioned air throughout the home more effectively than fixed-speed alternatives, reducing hot and cold spots.
Pros & Cons
Pros
- 16 SEER2 cooling efficiency exceeds the stated 15 SEER rating, delivering better summer performance than advertised
- 80% AFUE furnace with two-stage burner provides reliable heating for moderate climates without premium pricing
- Variable-speed blower motor with 2,000 CFM maximum airflow adapts to ductwork conditions for better comfort distribution
- 3.5 ton capacity handles 3 ton loads effectively, offering slight headroom for peak demand periods
- Energy Star certified system qualifies for utility rebates in most regions, reducing net installation cost
Cons
- 80% AFUE is baseline efficiency; high-efficiency furnaces reach 95% AFUE and save more on heating bills over time
- Single-stage cooling compressor cycles on and off rather than modulating, less efficient during partial load conditions
- 73.5 dB noise level is noticeably loud compared to variable-capacity competitors running at 65-68 dB
- R410A refrigerant availability will decline as industry transitions to R32 and R454B alternatives
Who Should Buy
Best For
Budget-conscious homeowners in moderate climates upgrading from 10+ year old systems will see meaningful energy savings without overpaying. Contractors installing replacement systems for price-sensitive customers will appreciate the AHRI certification, proven Goodman reliability, and quick turnaround ordering.
Consider Alternatives If
Buyers in extreme hot climates needing maximum cooling efficiency or those prioritizing quietest operation should explore variable-capacity systems with higher SEER2 ratings and staged compressors.
Installation
This upflow unit requires standard residential electrical service of 120V, 1 phase, 60 Hz with breaker capacity between 18.7 and 30 amps. The 30-inch height, 21-inch width and depth fit most standard closets and mechanical rooms. Metal exhaust flue piping is mandatory for the furnace. Professional installation remains strongly recommended for refrigerant charging and ductwork verification.
Warranty & Reliability
Goodman backs this unit with a 10-year parts and compressor warranty upon online registration. This comprehensive coverage extends protection beyond typical 5-year limited warranties, reducing replacement risk during the system's prime working years. Registration is mandatory to activate the full term, so verify completion during installation.
