A dual fuel system pairs an electric heat pump with a gas furnace, letting your home use either heat source as conditions change. The right package depends on more than its advertised tonnage or efficiency rating.
These 10 Goodman configurations span 1.5 to 3 tons and several furnace efficiencies. Use the comparisons below to identify promising options, then have an HVAC contractor verify the sizing and installation requirements.

The higher furnace AFUE and two-stage gas operation distinguish this 1.5-ton package. Confirm the heating and cooling loads independently, along with venting, condensate handling, and R-32 code compliance, before purchase.
How We Picked These Dual Fuel Furnace Systems
We compared the 10 listed Goodman packages using their published heat-pump capacity, SEER2 rating, furnace input rating, AFUE rating, Low NOx designation, and R-32 refrigerant. The selection covers 1.5- to 3-ton heat pumps, 40,000- to 100,000-BTU furnace inputs, and 80%, 92%, or 96% AFUE options. This is a comparison of listed specifications, not a claim that we tested the equipment or verified installed performance.
Quick Comparison
For a smaller cooling load, start by discussing the 1.5-ton packages with your installer; they differ substantially in furnace input and efficiency. The 2-ton group offers 60,000-BTU furnace options across 80%, 92%, and 96% AFUE. The 2.5-ton packages pair larger cooling capacity with 96% AFUE furnaces and either 60,000- or 80,000-BTU input. The 3-ton options list 80% AFUE furnaces with 80,000- or 100,000-BTU input. Listed SEER2 values are 14.5 or 15.2, so compare exact matched-system documentation rather than assuming one component determines the final rating.
Key Buying Factors for Dual Fuel Furnace Systems
Size Heating and Cooling Separately
Heat-pump tonnage describes nominal cooling capacity, while furnace BTU input describes fuel consumption at its rated firing rate—not the heat delivered into your ducts. A contractor should perform a heating and cooling load calculation and check duct airflow before recommending either size. Bigger equipment can cycle poorly and may not solve comfort problems.
Match Efficiency to Your Home and Climate
AFUE estimates the share of furnace fuel converted to usable heat under standardized conditions; higher AFUE can matter more when the furnace runs often. SEER2 describes seasonal cooling efficiency, but it does not by itself tell you how efficiently the heat pump heats in cold weather. Ask for the specific system’s heating-performance data and an estimated operating-cost comparison using local electricity and gas rates.
Confirm Installation Details
Higher-AFUE furnaces may require different venting and condensate drainage than an 80% AFUE replacement. Confirm that the indoor coil, outdoor unit, furnace, and dual-fuel controls are approved as a matched combination. Discuss the temperature or cost-based switchover strategy with your installer. Check local Low NOx rules, R-32 handling requirements, permits, and available rebates before ordering; eligibility can depend on the exact model combination.
Who Should Buy Which Dual Fuel Furnace Systems?
Choose a 1.5- or 2-ton candidate only if your calculated cooling load supports it, then select furnace input based on the heating load. Consider a 2.5-ton package when the home needs that cooling capacity and a 96% AFUE furnace suits its installation. Look at the 3-ton, 80% AFUE options when the load calculation calls for larger cooling capacity and the existing venting or project budget favors a non-condensing furnace. If furnace runtime is high, compare the 92% and 96% AFUE choices against installation costs—not just equipment prices. In every case, get a written quote for the complete matched system, controls, and required duct or vent changes.
