Review
Goodman's horizontal furnace and air conditioning system targets the contractor market with practical specs for attic and crawlspace installations. The 120,000 BTU heating capacity and 42,000 BTU cooling capacity address homes in moderate climates, while the compact horizontal footprint (26 inches wide, 21.125 inches deep) fits tight spaces. This unit emphasizes heating performance with its 97% AFUE rating and modulating burner technology. The system operates on both natural gas and propane, giving installers fuel flexibility on rural or underserved properties.
The 97% AFUE furnace efficiency sits among the best non-condensing alternatives and directly reduces monthly heating bills. The variable-speed ECM blower motor adapts to load conditions rather than running full-bore constantly, saving energy throughout the season. Cooling arrives via a scroll compressor with single-stage operation and R410A or R22 refrigerant compatibility. The 16 SEER2 rating meets ENERGY STAR criteria but trails high-end units approaching 18-20 SEER2. Maximum airflow of 2,000 CFM suits typical residential ductwork without oversizing concerns.
Pros & Cons
Pros
- 97% AFUE furnace rating puts it in the high-efficiency category, reducing heating costs substantially over time
- Modulating burner adjusts output continuously rather than simple on-off cycling, improving comfort and efficiency
- Variable-speed ECM blower motor runs at optimal speeds for each load, consuming less energy than fixed-speed alternatives
- PVC/plastic flue compatibility simplifies venting without expensive metal ductwork
- 10-year warranty with online registration provides meaningful protection on major components
Cons
- 3.5 ton cooling capacity lags behind the 5 ton furnace tonnage, creating an odd mismatch that suggests this is a furnace-only upgrade or partial replacement
- 16 SEER2 cooling efficiency is respectable but not exceptional for modern standards, won't maximize summer energy savings
- 73 dB noise level is moderately loud during furnace operation, noticeable in finished basements or bonus rooms
Who Should Buy
Best For
Contractors replacing furnaces in existing systems where ductwork and coil are already sized correctly. Homeowners in colder regions who prioritize heating efficiency and can justify the cost through natural gas savings over 10-15 years.
Consider Alternatives If
Anyone needing a balanced heating-cooling system should look elsewhere, since the tonnage mismatch indicates this combination may not perform optimally for both seasons.
Installation
This horizontal configuration requires right-side flue placement and PVC venting, both straightforward for most residential installations. Electrical demands range from 23.5 to 40 amp breaker sizing at 208/230V single-phase power. The 48-pound weight and compact dimensions make handling manageable for two installers. Refrigerant line sizing (3/8 inch liquid, 1 1/8 inch suction) and the 50-foot maximum line length are standard considerations for typical residential runs.
Warranty & Reliability
The 10-year parts warranty activates upon online registration and covers compressor, coil, and heat exchanger failures under normal conditions. This protection is industry-standard for mid-tier equipment. Warranty terms typically exclude wear items, improper installation, and lack of maintenance, so registration and proper service records matter significantly for claims.
