Review
The Goodman 3-ton vertical A-coil represents a solid middle-ground option in the residential cooling market. Built by one of North America's largest HVAC manufacturers and distributed through Online Supply, this unit targets contractors and homeowners looking to balance efficiency gains with reasonable pricing. The vertical 24.5-inch cased configuration solves spatial constraints in many existing installations, while the Energy Star certification signals modern refrigerant handling and performance standards.
Cooling capacity reaches 34,800 BTU with a 16 SEER1 efficiency rating, translating to approximately 20-25 percent better performance than baseline 13 SEER legacy equipment. The scroll compressor and R410A refrigerant combination delivers consistent operation across the 208/230V single-phase electrical spec. Noise runs at 73.5 dBA, comparable to other single-stage residential units. The 3/8-inch liquid and 7/8-inch suction line sizes integrate with standard field connections and 30-foot insulated suction line reduces jobsite fabrication.
Pros & Cons
Pros
- 16 SEER1 efficiency rating with Energy Star certification reduces operating costs versus older 13-15 SEER units
- Compact 29x29x38.25 inch vertical footprint fits tightly in basements, attics, and mechanical closets
- R410A refrigerant and scroll compressor provide proven reliability in residential applications
- 10-year warranty with online registration covers manufacturing defects and parts replacement
- 34,800 BTU cooling capacity handles 3-ton loads at manageable 73.5 dBA noise level
Cons
- 16 SEER1 spec is lower than newer 18-20+ SEER2 models currently entering the market
- Single-stage compressor lacks modulation capability for variable comfort or efficiency optimization
- Online Supply branding suggests HVAC distributor channel, not always available at retail
Who Should Buy
Best For
Contractors performing residential system replacements in moderate climates and homeowners seeking efficiency upgrades without premium pricing. This coil works especially well for systems serving 1,500-2,000 square foot homes where 3-ton capacity matches the load profile.
Consider Alternatives If
Buyers in high-efficiency-mandate markets should compare 18+ SEER2 models, and those needing variable capacity should look for dual-stage compressor options.
Installation
Installation requires standard HVAC practices with no unusual complications. The 30-pound weight allows two-person handling in tight spaces. Verify your furnace or air handler accepts upflow/downflow coil mounting before ordering. Electrical service must support 18.7 to 30-amp breaker sizing at 208/230V single-phase. Ensure proper refrigerant line sizing and connection to your condenser unit.
Warranty & Reliability
Goodman provides 10-year parts coverage when you register the unit online after installation. This covers refrigerant leaks, compressor failure, and component defects. Registration is straightforward through Goodman's website and typically takes minutes. No labor coverage is included, so factor in service call costs for repairs beyond the first year.
