Review
This Goodman 3-ton combo system occupies the sensible middle ground between budget equipment and premium offerings. Priced at $2,789, it combines an 80% AFUE furnace with an 18 SEER1 air conditioner in an upflow configuration. The unit weighs 30 pounds with compact 30-inch by 21-inch by 21-inch dimensions, fitting standard closet installations. It targets homeowners and contractors seeking tangible efficiency improvements without flagship pricing, backed by Goodman's established manufacturing reputation.
Performance specs reveal thoughtful design choices for mid-market buyers. The two-stage condenser produces 35,000 cooling BTU at 18 SEER1 efficiency, while the furnace delivers 80,000 BTU heating across two burner stages. A scroll compressor with variable-speed blower motor optimizes runtime efficiency, reducing cycling while maintaining airflow up to 2,000 CFM. The 71 dB noise level ranks significantly quieter than single-stage units. Electrical requirements are manageable, requiring 120V single-phase 60Hz service with breaker sizes between 21.3 and 35 amps.
Pros & Cons
Pros
- Two-stage condenser with 18 SEER1 rating runs quieter at 71 dB and reduces short-cycling
- Variable-speed blower motor with 2000 CFM maximum improves air distribution and comfort consistency
- 80% AFUE furnace handles 80,000 BTU heating output, sufficient for most 3-ton applications
- Energy Star certified with 10-year warranty including online registration
- Scroll compressor design proven for reliability and R410A/R22 compatibility
Cons
- 18 SEER1 lags behind high-end systems reaching 20+ SEER2 ratings
- 80% AFUE is baseline efficient, not condensing technology like 95% units
- Tonnage mismatch between 3.5-ton condenser and 3-ton rating creates slight oversizing
Who Should Buy
Best For
Homeowners in moderate climates seeking mid-range efficiency upgrades for homes requiring 3 tons of cooling and 80,000 BTU heating. Budget-conscious contractors installing residential systems where premium efficiency doesn't justify the cost premium.
Consider Alternatives If
Anyone needing condensing furnace technology, homeowners in extremely hot climates requiring maximum SEER ratings, or properties with limited electrical service under 21.3 amps.
Installation
Installation requires metal exhaust flue connections and proper refrigerant line sizing using the included 50-foot suction and 3/8-inch liquid lines. The A-coil style with 3/4-inch suction line insulation supports both upflow and horizontal configurations. Valve connections use sweat-type fittings sized at 3/4-inch suction and 3/8-inch liquid. Most contractors complete installation in 4 to 6 hours for straightforward ductwork. The CAPF installation manual and specifications sheet provide detailed guidance, though Adobe Reader is required.
Warranty & Reliability
Goodman covers this system with a 10-year warranty upon online registration. This protects against compressor failure, refrigerant leaks, and component defects. Coverage is comprehensive for a mid-tier product but does not include labor costs. Registration is mandatory within 30 days of installation. The evaporator coil carries separate coverage documentation included in the warranty package.
