Review
The Goodman 3-ton horizontal cased coil addresses a real market need for retrofit installations where space constraints rule out traditional vertical configurations. This unit delivers 34,800 BTU cooling capacity using a proven scroll compressor paired with R410A or R22 refrigerant compatibility. The horizontal A-coil design measures 24.5 inches tall, 26 inches wide, and 21.125 inches deep, fitting comfortably in tight attic and crawlspace applications where contractors commonly struggle with placement.
Efficiency is the main story here, with a 16 SEER1 rating that exceeds the advertised 15 SEER specification and qualifies for Energy Star recognition. The single-stage compressor uses 208/230V single-phase power with a 30-amp maximum breaker, keeping electrical requirements manageable on most residential panels. However, the single-stage design means the compressor runs at full capacity until satisfied, rather than modulating to part-load conditions, which can reduce overall seasonal efficiency during mild weather months.
Pros & Cons
Pros
- 16 SEER1 rating exceeds the 15 SEER rating claimed, delivering genuine Energy Star certification
- Compact horizontal design fits tight attic and crawlspace installations where traditional coils won't work
- Scroll compressor is proven technology with better reliability track record than rotary designs
- Dual refrigerant compatibility with R410A and R22 allows retrofit flexibility on existing systems
- 10-year warranty with registration provides solid coverage for parts and labor concerns
Cons
- Significant spec discrepancy: unit listed as both 3-ton and 5-ton creates confusion about actual cooling capacity
- 73.5 dB noise level runs moderately loud for residential use, especially in confined attic spaces
- Single-stage compressor cycles on and off rather than modulating, reducing efficiency under partial loads
- Price listed as $0 makes actual value assessment impossible for budget-conscious buyers
Who Should Buy
Best For
Contractors replacing damaged horizontal coils in attic-mounted systems or homeowners with tight retrofit spaces where conventional A-coils won't fit. This works well for humid climates where you need solid cooling without oversizing.
Consider Alternatives If
Anyone seeking variable-capacity cooling or quieter operation should explore two-stage alternatives, and builders installing new systems should opt for vertical A-coils offering better air distribution.
Installation
Installation requires proper refrigerant line sizing with 3/8-inch liquid and 7/8-inch suction connections, both supplied with 3/4-inch insulation over 50 feet of lineset. Horizontal mounting demands excellent condensate drainage slope to prevent water backup and mold growth. The 30-pound weight is manageable for two-person attic installation, though tight spaces may require careful maneuvering. Electrical connections remain straightforward on standard residential service.
Warranty & Reliability
Coverage includes a 10-year parts and labor warranty contingent on online registration with Goodman. This registration requirement is becoming standard industry practice and protects your investment against manufacturing defects. The Evaporator Coil Warranty document provides specific coverage details on refrigerant leaks and component failure. Registration typically takes minutes online and extends your protection window significantly beyond the first year.
