Review
This Goodman combo system targets contractors and homeowners looking for dependable heating-cooling without luxury pricing. The upflow A-coil configuration handles both heating and cooling in one package, delivering 100,000 BTU heating output and 45,500 BTU cooling capacity. At this price point, you're not getting high-end variable-capacity technology, but you are getting proven Goodman reliability and ENERGY STAR certification that shows real efficiency gains over older equipment.
The furnace runs at 80% AFUE with two-stage burner capability, meaning it adjusts heat output based on demand rather than running full-blast constantly. Cooling comes from a scroll compressor in single-stage configuration, which is efficient enough but not fancy. The variable-speed blower motor pulls up to 2,000 CFM and adapts to heating and cooling needs. R410A refrigerant compatibility ensures modern refrigerant standards. Electrical requirements are modest: 120V single-phase at 23.9 to 40 amps maximum.
Pros & Cons
Pros
- ENERGY STAR certified with 80% AFUE furnace efficiency and variable-speed blower motor for better comfort and lower utility bills
- Two-stage burner provides better heating control and responsiveness during cold snaps
- Scroll compressor is reliable workhorse technology found in thousands of installations across 10+ years
- A-coil design fits upflow/downflow configurations, giving installers flexibility on job sites
- 10-year warranty with online registration covers parts replacement and provides peace of mind
Cons
- Single-stage cooling means the compressor runs at full capacity or stops, lacking modulation for part-load efficiency
- 73 dB noise level is noticeably louder than premium inverter-driven systems, which matters in quiet neighborhoods
- Spec sheet shows both 4-ton and 5-ton tonnage claims, creating confusion about actual cooling capacity (45,500 BTU suggests closer to 3.8 tons)
Who Should Buy
Best For
This system fits homeowners in moderate climates who need reliable heating and cooling without spending premium dollars, and contractors managing renovation projects where budget constraints are tight. It's especially practical for properties where the existing ductwork and electrical service (120V, single-phase) are already established.
Consider Alternatives If
Skip this if you live in a hot climate requiring aggressive cooling cycles, want whisper-quiet operation, or need maximum efficiency to recover costs through utility savings.
Installation
Installation requires 3/8 inch liquid line and 1 1/8 inch suction line with 1/2 inch insulation, both pre-manufactured to 50 feet in length. You'll need metal exhaust flue for safe furnace venting. Mounting dimensions are compact at 30 inches high by 21 inches wide by 21 inches deep, fitting most closets and basements. Standard refrigerant connection procedures apply, though the dual refrigerant compatibility (R410A or R22) offers some flexibility on retrofit situations.
Warranty & Reliability
Goodman backs this unit with a 10-year parts warranty when you complete online registration after purchase. This covers compressor failure, motor burnout, and heat exchanger defects. Ten years typically aligns with realistic system lifespan, protecting against manufacturer defects during the critical early years when problems usually surface.
