Review
Goodman's 1.5 ton 14.5 SEER 96% AFUE gas furnace and heat pump system targets the mid-market segment where homeowners balance efficiency upgrades with budget constraints. This upflow A-coil configuration fits most existing installations, replacing the GSZ140191 model. Online Supply positions this unit as a straightforward, rebate-eligible option for dual-fuel heating and cooling without premium pricing.
Performance specs are genuinely strong for the price point. The furnace delivers 60,000 BTU heating output at 96% AFUE efficiency, meaning nearly every dollar spent on natural gas or propane converts to usable heat. The air conditioning side provides 18,000 BTU cooling at 14 SEER1 with a rotary compressor and variable-speed ECM blower motor. Maximum CFM reaches 1200, ensuring adequate airflow distribution across typical homes.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to older 80% units
- 14 SEER1 cooling rating with Energy Star certification for reliable air conditioning performance
- Two-stage burner and variable-speed ECM blower motor optimize comfort and reduce energy waste
- Lifetime heat exchanger warranty with 10-year parts coverage on registered units
- PVC/plastic exhaust flue compatibility simplifies installation in existing homes
Cons
- Single-stage condenser limits cooling modulation in extremely hot climates, reducing peak efficiency
- 70 dB noise level is moderately loud, louder than premium dual-stage units
- Specs show conflicting tonnage data (1.5 ton heating, 3 ton cooling capacity) suggesting potential matching issues
Who Should Buy
Best For
Homeowners in temperate to moderate climates replacing 15+ year old systems who prioritize heating efficiency and lower operating costs. Contractors installing budget-conscious upgrades where rebate incentives apply make this system a practical choice.
Consider Alternatives If
Anyone in extremely hot climates needing aggressive cooling performance or homes with tight noise restrictions should explore two-stage condenser models.
Installation
Installation requires 115V single-phase 60Hz power with 11.8 to 20-amp breaker sizing. The upflow configuration works in basements or utility closets. Suction lines demand 3/4-inch insulation thickness over 50 feet maximum, while liquid lines run 3/8-inch with sweat connections. PVC exhaust compatibility simplifies venting compared to steel flue requirements.
Warranty & Reliability
Goodman backs this system with lifetime coverage on the heat exchanger and 10 years of parts protection once registered online. This warranty structure protects against catastrophic furnace failures while limiting component replacement costs during the critical first decade of operation. Registration is mandatory to activate full coverage.
