Review
Goodman's 4 Ton two-stage system represents solid midmarket HVAC equipment that balances efficiency with affordability. The combination of a 96% AFUE gas furnace and 18 SEER2 air conditioner addresses both heating and cooling seasons effectively. This horizontal A-coil configuration suits homes with basement or attic installation space. The system carries ENERGY STAR certification and qualifies for many utility rebates, making it attractive to cost-conscious homeowners and contractors.
The furnace delivers 120,000 BTU across two burner stages, while the air conditioner provides 47,000 BTU cooling capacity with a scroll compressor. The variable-speed ECM blower motor adjusts between 0 and 2,000 CFM based on demand, improving efficiency and reducing unnecessary runtime. Operating at 72 dB, noise levels remain reasonable for most installations. The two-stage approach on both heating and cooling sides means the system runs at partial capacity during mild weather, consuming less energy than single-stage competitors.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs substantially, with two-stage burners optimizing performance across temperature ranges
- 18 SEER2 rating on cooling side qualifies for ENERGY STAR certification and most utility rebates
- Variable-speed ECM blower motor adapts to demand, improving comfort and reducing runtime noise to 72 dB
- Two-stage scroll compressor and condenser deliver consistent cooling at 47,000 BTU with modulation capability
- Lifetime heat exchanger warranty plus 10 years parts coverage with registration provides solid protection
Cons
- Spec sheet lists contradictory tonnage, 5 ton vs 4 ton in title, creating potential confusion during ordering
- Requires licensed HVAC technician for installation, cannot be DIY project in most jurisdictions
- 72 dB noise level is moderately loud for some applications, higher than premium variable-speed systems
Who Should Buy
Best For
Homeowners in mixed climates with moderate to high heating and cooling demands who prioritize efficiency without premium pricing. Budget-conscious contractors value Goodman's two-stage reliability and strong rebate eligibility.
Consider Alternatives If
Anyone seeking ultra-quiet operation or already committed to a different brand's ecosystem should explore premium alternatives with lower sound ratings.
Installation
Installation requires a licensed HVAC technician due to gas line connections and venting requirements. The system uses R410A refrigerant with 3/8 inch liquid and 7/8 inch suction lines. Electrical requirements are 115V single-phase 60Hz with 29.3 to 50 amp breaker sizing. Plastic PVC exhaust flue is acceptable. Proper gas connections are critical, as incorrect installation creates serious safety hazards.
Warranty & Reliability
Goodman backs this unit with a lifetime heat exchanger warranty and 10 years parts coverage when registered online. The heat exchanger lifetime coverage is industry-standard for this brand and reflects confidence in furnace longevity. Parts coverage at 10 years provides meaningful protection for compressors, motors, and electrical components during peak failure risk periods.
