Review
The Goodman 4-ton gas furnace and air conditioner system represents the practical middle ground in residential HVAC equipment. This upflow configuration comes pre-assembled as a complete package priced at $2071, making it an accessible option for homeowners and contractors managing replacement budgets. It's positioned squarely in the mid-tier market, offering genuine Energy Star certification without premium pricing or cutting corners on core components.
This system delivers 80,000 BTU of heating through an 80% AFUE two-stage furnace and 45,500 BTU of cooling capacity with a 16 SEER1 rating. The variable-speed blower motor reaches 2000 CFM maximum, allowing the furnace to operate efficiently during partial-load conditions. Single-stage scroll compressor cooling with R410A/R22 compatibility provides reliable refrigeration, though it lacks the modulation efficiency of two-stage alternatives.
Pros & Cons
Pros
- Energy Star rated with 80% AFUE furnace efficiency, reducing heating costs versus older baseline equipment
- 5-ton cooling capacity with 45,500 BTU cooling output paired with 80,000 BTU heating in single unit
- Variable-speed blower motor adjusts airflow up to 2000 CFM, improving comfort and reducing runtime noise
- Two-stage burner allows furnace to run at lower capacity during mild weather, saving fuel
- Scroll compressor technology is reliable and widely serviced, with 10-year warranty when registered
Cons
- Single-stage air conditioner limits cooling efficiency compared to two-stage alternatives at similar price points
- 73 dB noise level is moderate, not ideal for noise-sensitive installations near living spaces
- 80% AFUE is respectable but trails high-efficiency 95% AFUE systems that qualify for utility rebates in some markets
Who Should Buy
Best For
Homeowners in the South and Southwest replacing 10-15 year old split systems who rent their properties or plan to move within 8 years. Contractors installing budget-conscious retrofit jobs for price-sensitive customers where utility rebates aren't available.
Consider Alternatives If
Anyone in cold climates (Minnesota, Wisconsin, Canada) should look at 90+ AFUE units, and buyers in areas offering substantial utility rebates for high-efficiency equipment should evaluate variable-capacity systems instead.
Installation
Installation requires standard 3/8 inch liquid and 1 1/8 inch suction refrigerant lines with 1/2 inch insulation wrap (50 feet included). The 120V single-phase 60Hz electrical connection needs a 23.9 to 40-amp breaker. Metal exhaust flue is required. Dimensions of 30 inches high by 24.5 inches wide by 21 inches deep fit standard closets and basements.
Warranty & Reliability
Goodman includes a 10-year parts and labor warranty when you register online within 30 days of installation. This covers compressor, furnace heat exchanger, and evaporator coil defects. Registration is straightforward through Goodman's website and extends your protection during the critical first decade of operation when most failures occur.
