Review
The Goodman 3-ton horizontal system bridges the gap between budget and performance in the mid-market HVAC segment. This unit combines a 96% AFUE furnace with 16 SEER2 cooling capability, making it relevant for homeowners tired of high utility bills but unwilling to spend premium prices. Goodman's reputation for solid reliability and this system's horizontal A-coil design address real pain points for contractors working in tight residential spaces across diverse climates.
Heating delivers a robust 120,000 BTU capacity through a two-stage burner, while cooling provides 34,800 BTU output from a scroll compressor. The variable-speed ECM blower motor handles up to 2,000 CFM, automatically adjusting to match heating and cooling demand rather than running at constant speed. This translates to measurable energy savings during moderate weather and quieter operation compared to fixed-speed alternatives, though the single-stage condenser means it won't modulate efficiency on 60-degree spring days.
Pros & Cons
Pros
- 96% AFUE heating efficiency reduces winter gas bills significantly compared to 80-90% units
- 16 SEER2 cooling rating beats many competitors in the mid-tier price range
- Variable-speed ECM blower motor adjusts airflow automatically, improving comfort and reducing runtime costs
- Two-stage burner and single-stage compressor provide steady, quiet operation at 73.5 dB
- PVC/plastic exhaust flue requirement simplifies installation in homes without traditional metal chimneys
- 10-year warranty with online registration covers parts and labor on major components
- Horizontal A-coil configuration fits perfectly in attics and crawl spaces where vertical units won't fit
Cons
- Single-stage condenser means cooling doesn't modulate in mild weather, reducing efficiency on moderate days
- Specs list both 3-ton and 3.5-ton ratings, creating potential confusion about actual capacity and matching requirements
- 73.5 dB noise level runs slightly louder than premium competitors during full-load operation
- R410A or R22 refrigerant flexibility suggests possible compatibility issues if you need specific refrigerant type
Who Should Buy
Best For
Contractors upgrading older furnaces in homes with attic or crawl space placement, and homeowners in regions where propane is the primary heating fuel. Budget-conscious buyers who prioritize upfront savings without sacrificing efficiency ratings will find good value here.
Consider Alternatives If
Anyone needing a variable-capacity condenser for truly quiet, efficient cooling in mild climates should look at two-stage or inverter-driven systems instead.
Installation
Installation requires 208/230V single-phase 60 Hz power with a minimum 18.7-amp breaker and maximum 30-amp capacity. The horizontal configuration measures 24.5 inches tall by 21.125 inches wide by 26 inches deep, fitting most standard attic openings. PVC exhaust flue compatibility eliminates the need for traditional metal ductwork, speeding installation in many homes. Proper refrigerant line sizing uses 3/8-inch liquid and 7/8-inch suction lines with 3/4-inch insulation thickness.
Warranty & Reliability
Online registration unlocks a 10-year parts and labor warranty covering the furnace, air conditioning components, and evaporator coil. This extended coverage is unusual at this price point and protects against manufacturer defects. Keep registration documentation accessible, as claims require proof of purchase and professional installation. Warranty does not cover misapplication, improper maintenance, or refrigerant issues from poor workmanship.
