Review
This Goodman 3.5-ton horizontal system represents a practical middle ground for contractors and homeowners seeking genuine efficiency improvements without premium pricing. The combination of 80,000 BTU heating capacity and 35,000 BTU cooling output addresses mixed-climate applications effectively. Goodman's reputation for straightforward, durable equipment carries through here, backed by a 10-year warranty with online registration. The horizontal A-coil design specifically targets installations in attics, basements, and crawlspaces where vertical coils simply won't fit, making this particularly valuable for retrofit work in existing homes.
Performance metrics justify the efficiency claims. The 96% AFUE furnace rating means you're recovering nearly all combustion heat, translating to real savings on monthly gas bills. On the cooling side, 18 SEER1 and ENERGY STAR qualification open doors to utility rebates that can offset equipment cost. The two-stage compressor paired with a variable-speed ECM blower motor means the system runs at partial capacity during mild weather rather than cycling on and off constantly. This staged operation keeps noise down to 71 dB and extends component lifespan by reducing thermal stress. Scroll compressor design adds reliability compared to older reciprocating models.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to 80-85% models
- 18 SEER1 cooling efficiency, plus ENERGY STAR certification, qualifies for most utility rebates
- Two-stage compressor and variable-speed ECM blower motor deliver quiet operation at 71 dB
- Horizontal A-coil configuration fits attics and crawlspaces where vertical units won't work
- Two-stage burner adapts to heating demand, avoiding inefficient full-load cycling
- Scroll compressor design is proven reliable with fewer moving parts than reciprocating alternatives
Cons
- Price listing at $89 appears to be coil-only or incomplete system quote, not full installed cost
- Specifications show conflicting tonnage (title says 3 ton, specs list 3.5 ton) creating confusion
- PVC exhaust flue requirement limits installation options in some older homes with masonry chimneys
- Requires proper refrigerant charging and line insulation (3/4 inch thickness specified) for warranty validity
Who Should Buy
Best For
Contractors replacing complete systems in homes where horizontal equipment installation is necessary, and homeowners in regions with significant heating and cooling seasons who want efficiency rebates. This unit appeals to budget-conscious buyers who won't sacrifice performance for price.
Consider Alternatives If
Those with tight electrical service (requires 21.3-35 amp breaker dedicated circuit) or homes unable to accommodate PVC exhaust venting should explore alternatives.
Installation
Installation requires standard 115V, 1-phase 60 Hz power with a 21.3-35 amp dedicated breaker. The unit weighs 30 pounds, manageable for positioning in tight spaces. Refrigerant lines use 3/8-inch liquid and 7/8-inch suction connections with 3/4-inch insulation thickness mandatory for warranty. PVC exhaust venting is required, which simplifies ducting compared to masonry flue systems but eliminates that option for older homes. Proper evacuation and charging are critical for performance and warranty coverage.
Warranty & Reliability
The 10-year parts warranty activates with online registration, a standard industry practice that protects against defects in materials and workmanship. Coverage is limited to parts only, not labor or refrigerant. This duration is competitive for mid-range equipment. Keep records of installation and annual maintenance to validate warranty claims if issues arise.
