Review
The Goodman 5-ton gas furnace and air conditioner combination represents a solid middle-ground option in the residential HVAC market. Manufactured by a company with decades of OEM experience, this horizontal A-coil configuration handles both heating and cooling in a single integrated system. Priced at $3,136 before installation, it positions itself as an affordable entry point for homeowners replacing aging equipment or for contractors seeking reliable inventory without premium pricing.
Performance numbers tell the real story here. The cooling side delivers 54,000 BTU with a 16 SEER rating, meaning seasonal efficiency roughly 30 percent better than 13 SEER baseline units. The heating side produces 120,000 BTU at 96% AFUE using a two-stage burner that modulates between high and low fire. The variable-speed ECM blower adjusts between zero and 2,000 CFM, optimizing airflow for both heating and cooling rather than running at constant speed. These efficiency gains translate directly to lower monthly utility costs, especially during peak heating and cooling months.
Pros & Cons
Pros
- 16 SEER rating qualifies for Energy Star certification, reducing cooling energy costs by roughly 30 percent versus older systems
- 96% AFUE furnace efficiency means minimal gas waste during heating season, translating to lower winter utility bills
- Two-stage burner adjusts heating output automatically, improving comfort and reducing cycling losses on mild days
- Variable-speed ECM blower motor runs efficiently at multiple speeds rather than on/off only, cutting electricity consumption
- 10-year warranty with online registration provides reasonable protection without requiring additional service plans
- Scroll compressor design offers quieter operation at 73 dB and proven reliability in residential applications
Cons
- Single-stage cooling compressor cannot modulate capacity, so efficiency drops during part-load conditions like spring and fall
- Cooling BTU rating of 54,000 seems mismatched to the 120,000 heating BTU, suggesting this may be a less common tonnage pairing
- Plastic PVC exhaust flue requirement limits installation options in certain climates where condensation freezing becomes problematic
- No variable refrigerant flow means you cannot reduce capacity when outdoor temperatures are mild
Who Should Buy
Best For
Homeowners in moderate climates who run their AC three to five months yearly and prioritize heating efficiency will see strong ROI on this system. Contractors looking for reliable mid-tier equipment to bundle with installation labor and maintain healthy margins should consider this product seriously.
Consider Alternatives If
Skip this if you live in extreme climates requiring year-round heavy cooling, want a two-stage AC compressor for efficiency in shoulder seasons, or need premium warranty coverage extending beyond ten years.
Installation
This horizontal downflow unit requires standard split-system installation with proper line set sizing, electrical work for 115V single-phase 60 Hz power, and adequate breaker capacity between 29.6 and 50 amps. The plastic PVC exhaust flue requirement simplifies venting in most homes but may require modifications in areas prone to condensation freezing. Standard ductwork connections and refrigerant charging round out the typical four to six hour installation window.
Warranty & Reliability
Goodman backs this system with a full 10-year parts and labor warranty when you complete online registration after purchase. This coverage protects against manufacturing defects in the compressor, heat exchanger, and major components. Registration is straightforward and critical, as the warranty defaults to five years without it. This is competitive with entry-level equipment but falls short of premium brands offering 12 to 15 year warranties.
