Review
Goodman's 3-ton downflow system pairs a high-efficiency gas furnace with an air conditioning coil in one compact footprint. Priced at $732 through Online Supply, it targets contractors and homeowners seeking mid-market efficiency without flagship pricing. The unit arrives as a complete assembly weighing 30 pounds, measuring 30 inches tall by 17.5 inches wide by 21 inches deep, fitting standard downflow or horizontal applications. Energy Star certification and modulating burner technology signal Goodman's commitment to part-load efficiency.
The furnace delivers 60,000 BTU heating output with a best-in-class 97% AFUE rating, meaning 97 cents of every gas dollar converts to usable heat. On the cooling side, the 18 SEER2 rating (advertised specs show SEER1 as 18) translates to roughly 2.1 watts of cooling per BTU, substantially better than 15 SEER2 baseline units. The two-stage scroll compressor runs on standard 115V single-phase power, drawing between 21.3 and 35 amps depending on stage and outdoor temperature. Variable-speed ECM blower modulates up to 1200 CFM, meaning lower motor runtime during mild weather.
Pros & Cons
Pros
- 97% AFUE furnace efficiency with modulating burner stages minimizes energy waste during partial-load heating cycles
- 18 SEER2 cooling efficiency on air conditioning side outperforms baseline 15 SEER2 units, cutting AC runtime costs noticeably
- Variable-speed ECM blower motor adjusts airflow between 0 and 1200 CFM, reducing parasitic fan energy draw
- Two-stage scroll compressor with soft-start electronics reduces electrical strain and extends compressor lifespan
- PVC exhaust compatibility and plastic flue requirement simplifies venting in tight attic or basement installations
- 10-year parts warranty with online registration covers manufacturing defects adequately for mid-market buyers
Cons
- Spec sheet lists contradictory cooling BTU values (35,000 stated versus expected 36,000 for true 3-ton capacity), creating uncertainty about actual capacity
- No single-stage option limits flexibility for contractors wanting simpler, lower-cost configurations
- 71 dB noise level runs slightly louder than premium variable-speed units, noticeable during heating ramp-up
- Limited documentation provided (manual PDFs only, no quick-start guides), requiring contractor familiarity with Goodman systems
Who Should Buy
Best For
Contractors retrofitting older 3-ton splits with efficient all-in-one units, or homeowners in regions with cold winters and hot summers wanting payback through reduced utility bills. This system fits well in downflow installations where basement or attic space is constrained.
Consider Alternatives If
Buyers needing premium quietness, those wanting a single-stage configuration, or anyone uncomfortable registering online to activate the 10-year warranty.
Installation
Installation requires sweat-type refrigerant connections using 3/8-inch liquid line and 7/8-inch suction line with 3/4-inch foam insulation. PVC plastic exhaust flue simplifies vent routing compared to metal alternatives. Standard 115V electrical outlet suffices, though breaker sizing between 21.3 and 35 amps must be verified at installation. Downflow orientation demands clear vertical space below the unit for airflow path.
Warranty & Reliability
A 10-year parts warranty covers manufacturing defects, compressor failure, and coil leaks when registered online within 30 days of purchase. Labor remains excluded, meaning homeowners pay service calls separately. This coverage aligns with mid-tier brands and protects against catastrophic failures during the system's peak reliability window.
