Review
The Goodman 5-ton combination system represents smart engineering at accessible pricing. This horizontal configuration pairs an 80,000 BTU furnace with a 60,000 BTU air conditioner, delivering full-capacity performance for mid-sized residential installations. Online Supply's $2,071 price point positions this unit directly in the sweet spot where contractors can specify solid equipment without inflating customer quotes. The 10-year warranty and broad compatibility with existing ductwork make it a practical choice for replacement jobs.
Efficiency numbers tell a meaningful story here. The 80% AFUE furnace converts 4 out of every 5 BTU into usable heat, while the 13 SEER air conditioner delivers roughly 13 BTU of cooling per watt consumed. These aren't premium ratings, but they substantially outpace 10 SEER units. The variable-speed blower motor adjusts CFM from baseline to 2,000 maximum, reducing energy waste during mild weather. Two-stage burner operation prevents constant on-off cycling that plagues single-stage units. Combined, these features lower utility bills without requiring a second mortgage.
Pros & Cons
Pros
- Two-stage burner and variable-speed blower reduce short-cycling and improve comfort during partial-load heating
- 80,000 BTU heating output paired with 60,000 BTU cooling handles full 5-ton loads reliably
- 13 SEER rating outperforms baseline 10 SEER units by 30% efficiency, cutting cooling costs meaningfully
- Horizontal configuration with A-coil design simplifies attic or utility closet installation in tight spaces
- 10-year parts and labor warranty with registration provides solid protection at this price point
Cons
- 80% AFUE is respectable but lags behind 95% AFUE high-efficiency furnaces by 15 percentage points in heating savings
- Single-stage condenser cannot modulate cooling capacity, running at full output even during mild weather
- 77 dB noise level runs audibly louder than variable-speed units, noticeable in quiet home environments
- Not Energy Star certified, meaning it meets minimum standards but lacks independent efficiency verification
Who Should Buy
Best For
Contractors installing replacement systems for mid-sized homes (2,000-2,500 sq ft) and budget-conscious homeowners willing to accept good efficiency without premium pricing. This unit performs particularly well in climates with balanced heating and cooling loads.
Consider Alternatives If
Buyers prioritizing maximum efficiency, homes requiring ultra-quiet operation, or regions with extreme heating demands should explore 95% AFUE furnaces or variable-capacity compressor systems instead.
Installation
Installation demands careful attention to electrical requirements and refrigerant line work. This unit requires 208-230V single-phase 60 Hz power with breaker sizing between 32.8 and 45 amps, necessitating proper load calculations before installation. Suction and liquid lines measure 7/8-inch and 3/8-inch respectively, with sweat valve connections requiring competent brazing. Horizontal mounting requires stable structural support and adequate clearance for the 40-inch height and 29-inch depth. Metal flue exhaust venting must be properly sized and sealed.
Warranty & Reliability
Goodman's 10-year warranty covers parts and labor when registered within 30 days of installation. Registration is straightforward and unlocks full coverage against manufacturing defects. This warranty period matches industry mid-tier standards, offering meaningful protection without reaching premium extended options. Contractors should emphasize registration importance to customers, as unregistered units receive limited coverage.
