Review
Goodman's 3-ton gas furnace and air conditioning system represents the sweet spot for many residential replacements. This upflow A-coil configuration ships as a matched pair, simplifying both ordering and system optimization. The brand's reputation for durability makes it a contractor favorite, while the Energy Star certification appeals to cost-conscious homeowners. Online Supply positions this unit competitively in the mid-tier market where quality and affordability balance.
The 97% AFUE furnace with modulating burners delivers efficient heating through 100,000 BTU output, while the air conditioner pulls 34,800 BTU cooling capacity at 16 SEER efficiency. The variable-speed ECM blower adjusts airflow up to 2000 CFM based on demand, reducing electricity waste during partial-load operation. R410A refrigerant meets current environmental standards. Electrical requirements are reasonable at 115V single-phase with 18.7 to 30 amp breaker sizing.
Pros & Cons
Pros
- 97% AFUE furnace efficiency significantly reduces heating costs compared to 80-90% units
- 16 SEER cooling efficiency qualifies for Energy Star and various utility rebates
- Modulating burner and variable-speed ECM blower optimize performance across different heating demands
- 100,000 BTU heating capacity handles most residential needs without oversizing
- A-coil configuration works in upflow or horizontal installations for flexible placement
Cons
- Single-stage compressor means cooling cycles on and off rather than modulating for quieter operation
- 73.5 dB noise level is moderately loud, noticeable during operation in quiet spaces
- Spec inconsistency shows both 3-ton and 5-ton ratings, creating confusion about actual capacity
Who Should Buy
Best For
Homeowners in mixed-climate zones replacing 15+ year old systems who want proven Goodman reliability at competitive pricing. This combination works well for houses where heating and cooling demands are roughly equal throughout the year.
Consider Alternatives If
Buyers in extremely hot climates seeking maximum cooling should consider higher-tonnage units, and noise-sensitive homeowners would benefit from dual-stage or modulating compressors.
Installation
This upflow A-coil system requires standard ductwork modifications and proper line sizing. The 3/8-inch liquid and 7/8-inch suction lines come with 3/4-inch insulation included. Flue exhaust requires plastic or PVC venting to the right side. Most residential installations take 4 to 6 hours for experienced technicians. Proper refrigerant charging and airflow verification are critical for achieving rated efficiency.
Warranty & Reliability
The 10-year parts warranty requires online registration within a specified timeframe after installation. This is stronger than many budget-tier competitors offering 5 years. Coverage typically includes compressor, heat exchanger, and sealed components. Verify registration deadlines and coverage exclusions with your installer to protect your investment.
