Review
Goodman remains one of the most accessible split system brands for contractors and homeowners balancing performance with cost. This particular configuration combines a high-efficiency 97% AFUE furnace with a 16 SEER air conditioner condenser, both Energy Star rated. The upflow configuration and A-coil design suit retrofit installations in homes with basements or crawl spaces. The modulating burner and variable-speed blower suggest Goodman positioned this unit as a mid-tier efficiency option rather than budget baseline.
The furnace delivers 120,000 BTU heating capacity with modulating burner stages that continuously adjust output rather than cycling on and off. The air conditioner handles 42,000 BTU cooling using a scroll compressor in single-stage operation, paired with R410A or R22 refrigerant compatibility. The variable-speed ECM blower reaches 2000 CFM maximum and ramps automatically based on demand, which typically improves efficiency by 10 to 15 percent compared to fixed-speed motors. The 97% AFUE rating reflects excellent heat exchanger design and combustion efficiency.
Pros & Cons
Pros
- 97% AFUE furnace efficiency minimizes heating waste and fuel costs, especially valuable in cold climates
- 16 SEER condenser meets Energy Star standards with single-stage scroll compressor reliability
- Modulating burner stages enable precise heating output, reducing temperature swings and improving comfort
- Variable-speed ECM blower motor automatically adjusts airflow from 0 to 2000 CFM for optimal efficiency
- 10-year warranty with online registration provides solid coverage and manufacturer support
- PVC exhaust flue compatibility simplifies installation in modern homes with plastic ductwork
Cons
- Single-stage air conditioning lacks the efficiency gains of two-stage or variable-capacity systems
- 73 dB noise level is moderately loud for cooling operation, noticeable in quiet neighborhoods
- Product listing shows spec inconsistencies (title states 3.5 tons, specs list 5 tons), requiring clarification before purchase
- Requires 23.5 to 40 amp electrical service, potentially demanding upgraded breaker panels in older homes
Who Should Buy
Best For
This system suits homeowners in moderate to cold climates upgrading older furnaces who prioritize heating efficiency and want Energy Star certification without paying for advanced staging. It works well in homes requiring 3.5 to 5 tons of capacity with adequate electrical service already installed.
Consider Alternatives If
Skip this system if you live in consistently hot climates where cooling dominates, need ultra-quiet operation below 70 dB, or want variable-capacity cooling for maximum efficiency.
Installation
This upflow unit requires 115V single-phase 60 Hz power with 23.5 to 40 amp breaker sizing, so electrical service assessment is essential before ordering. The plastic PVC exhaust flue simplifies venting compared to metal options. Installation demands proper refrigerant line sizing, with 3/8 inch liquid and 1 1/8 inch suction lines specified, plus half-inch insulation on suction lines to prevent condensation loss. CAPF installation manual and AHRI certificate 7424268 provide documentation for licensed installers.
Warranty & Reliability
Goodman provides a 10-year parts warranty when registered online, a standard industry offering for residential systems. Registration typically takes minutes through the manufacturer website. Coverage extends to compressor, heat exchanger, and other major components, though labor is usually excluded. This warranty protects against manufacturing defects but not installation issues or refrigerant losses.
