Review
This Goodman 3-ton split system combines an 80,000 BTU furnace and 36,000 BTU air conditioner into a practical solution for homeowners seeking reliable climate control without luxury-tier spending. Manufactured by Online Supply with an AHRI certificate number 204633302, it represents the middle ground in the market, offering proven Goodman components in a straightforward upflow A-coil configuration. The $2,700 price reflects its solid-but-not-premium positioning among contractors and DIY installers familiar with Goodman's reputation for durability.
Performance specs reveal competent engineering for typical residential applications. The 36,000 BTU condenser achieves 14 SEER1 efficiency using R410A refrigerant and a scroll compressor, while the furnace delivers 80% AFUE through two-stage gas burners. The variable-speed blower reaches 2,000 CFM maximum airflow, adapting to home conditions rather than running constantly. At 73 dB, operation is noticeable but acceptable for basements or utility closets. Electrical requirements stay modest at 120V single-phase with a 30-amp maximum breaker, simplifying retrofit installations.
Pros & Cons
Pros
- 14 SEER cooling efficiency beats baseline 13 SEER units by approximately 8 percent, translating to measurable energy savings
- Two-stage burner adjusts heating output for better comfort and lower fuel consumption during mild weather
- Variable-speed blower motor cycles based on demand, reducing runtime and electricity usage compared to single-speed alternatives
- Metal exhaust flue requirement is standard industry practice, with 30 feet of suction line insulation included for simplified installation
- 10-year warranty with online registration covers parts and compressor, providing reasonable peace of mind for residential use
Cons
- 80% AFUE is acceptable but not exceptional, lacks the 90-plus AFUE efficiency of high-end condensing furnaces
- Single-stage air conditioning compressor means no variable capacity for mild days, unlike two-stage or inverter-driven units
- 73 dB noise level is moderately loud, higher than premium variable-speed systems that operate closer to 65-68 dB
- Not Energy Star certified, indicating it meets minimum standards rather than above-average efficiency benchmarks
Who Should Buy
Best For
This system suits homeowners in moderate climate zones replacing 10-plus year old equipment who prioritize reliability and upfront affordability. It's ideal for properties where utility costs are secondary to avoiding expensive emergency repairs or where cooling loads remain moderate year-round.
Consider Alternatives If
Skip this unit if you live in extreme heat regions demanding maximum cooling efficiency, need the quietest operation, or want premium warranties exceeding 10 years.
Installation
Installation follows conventional practices for upflow systems in basements or crawlspaces. The A-coil design integrates above the furnace, requiring vertical space around 34.5 inches high by 21 inches wide. Metal exhaust flue installation is mandatory for safety compliance. Pre-installed 30 feet of 3/4-inch suction line insulation expedites field connections, reducing labor time compared to older systems requiring manual insulation wrapping. Licensed HVAC technicians typically complete full installation in 4-6 hours.
Warranty & Reliability
Goodman provides 10-year parts and compressor coverage upon online registration, which requires minimal effort through their website. This matches industry standard for mid-tier systems and protects against manufacturing defects and component failures. Registration is important, as non-registered units default to shorter coverage. The warranty excludes wear items like capacitors and contactors under heavy use, but covers the sealed compressor and major components.
