A hybrid heat pump pairs electric heat-pump operation with a second heating source for colder conditions, but the five systems below use gas furnaces—not oil boilers. They are relevant comparisons for shoppers considering dual-fuel heating, but they are not direct oil-boiler packages. The Goodman 15.2 SEER2 options suit buyers comparing matched 2.5-ton systems; the Oxbox package is a larger 4-ton option with an 80,000 BTU furnace.
| Product | Best For | Key Listed Details |
|---|---|---|
| Oxbox by Trane 4-ton system | Larger homes or systems specified for 4 tons | 14.3 SEER2; 80,000 BTU, 80% AFUE gas furnace |
| Goodman 2.5-ton, 100,000 BTU system | Buyers needing the highest listed furnace input among these options | 15.2 SEER2; 100,000 BTU, 80% AFUE furnace |
| Goodman 2.5-ton, 80,000 BTU system | Buyers comparing a 15.2 SEER2 matched system | 15.2 SEER2; 80,000 BTU, 80% AFUE furnace |
| Goodman 2.5-ton, 14.5 SEER2 system | Buyers seeking a matched 2.5-ton package | 14.5 SEER2; 80,000 BTU, 80% AFUE furnace |
| Goodman 2.5-ton, 14.5 SEER2 system with alternate furnace | Buyers comparing a separate listed model combination | 14.5 SEER2; 80,000 BTU, 80% AFUE furnace |
Oxbox 4-Ton Heat Pump And Furnace
Best for: Buyers whose home and HVAC design call for a 4-ton system and who want a packaged heat pump with gas-furnace backup. This is the largest-capacity option in this selection.
The listed package includes a 4-ton heat pump, a cased evaporator coil, and an 80,000 BTU gas furnace rated at 80% AFUE. The heat pump has a listed 14.3 SEER2 rating and is described as compatible with R-454B refrigerant. The package is presented as a dual-fuel system for heating and cooling.
Why it was selected: Its higher listed system capacity makes it a useful comparison for homes that need more capacity than the 2.5-ton Goodman packages. Furnace input and cooling-efficiency figures are stated clearly in the supplied product details.
Limitation: This is a gas-furnace system, not an oil-boiler hybrid. Its 4-ton capacity should not be treated as a recommendation without a professional load calculation.
Goodman 2.5-Ton System With 100,000 BTU Furnace
Best for: Buyers comparing a 2.5-ton dual-fuel package with the highest listed furnace input in this group. The included gas furnace is rated at 100,000 BTU and 80% AFUE.
The package includes a Goodman R-32 heat pump, a cased evaporator coil, and the gas furnace. The listed 15.2 SEER2 rating applies to the complete matched combination, rather than to an individual component. The product information identifies AHRI certificate 215217839 for that matched rating.
The heat pump is described as single-stage, with its compressor operating at full output when the thermostat calls for heating or cooling. The coil is cased, has a factory-installed TXV, and is described as an upflow/downflow model.
Why it was selected: It combines the group’s highest listed SEER2 figure with a 100,000 BTU furnace, making it a distinct option for buyers comparing furnace input alongside cooling efficiency.
Limitation: The 100,000 BTU figure does not establish that this furnace is correctly sized for a particular home. It is gas-fired, not oil-fired.
Goodman 2.5-Ton 15.2 SEER2 System
Best for: Buyers who want to compare a 15.2 SEER2 matched system with an 80,000 BTU gas furnace, rather than the 100,000 BTU version above.

The heat pump is single-stage and runs at full output when there is a heating or cooling call. The horizontal cased coil includes a factory-installed TXV. These details can help a buyer and installer check whether the listed configuration fits the intended equipment layout.
Why it was selected: It offers the same listed 2.5-ton and 15.2 SEER2 figures as the 100,000 BTU Goodman option, but with a lower furnace input rating.
Limitation: It is not an oil-boiler package, and its single-stage operation is not variable-capacity operation. Confirm the matched components and installation requirements with an HVAC professional.
Goodman 2.5-Ton 14.5 SEER2 Heat Pump System
Best for: Buyers comparing a 2.5-ton system with a listed 14.5 SEER2 rating and an 80,000 BTU gas furnace.
This package includes the GLZS5BA3010 R-32 heat pump, CHPTA3026B3 horizontal cased evaporator coil, and GR9S800803BN furnace. The supplied details identify AHRI certificate 215382579 for the matched combination’s 2.5-ton and 14.5 SEER2 rating. The furnace is listed at 80% AFUE and 80,000 BTU.
The heat pump is single-stage. The coil has a factory-installed TXV and an all-aluminum construction, according to the product information. The matched system provides a like-for-like capacity comparison with the other Goodman 2.5-ton packages, while its listed efficiency differs.
Why it was selected: It gives shoppers another documented Goodman matched combination to compare against the 15.2 SEER2 options, with the same stated furnace input as several alternatives.
Limitation: The listed 14.5 SEER2 figure is for the full matched combination, not the heat pump alone. This is a gas-furnace system rather than a heat pump paired with an oil boiler.
Goodman 2.5-Ton System With Alternate Furnace
Best for: Buyers who want a second listed 2.5-ton Goodman configuration with a 14.5 SEER2 matched rating and an 80,000 BTU gas furnace.
The listed components are the GLZS4BA3010 R-32 heat pump, CHPTA3026B3 horizontal cased coil, and GR9T800803BN gas furnace. The product details associate the complete combination’s 2.5-ton and 14.5 SEER2 figures with AHRI certificate 215218856. The furnace is rated at 80% AFUE and 80,000 BTU.
Like the other listed Goodman options, this heat pump is described as single-stage and runs at full output when called. The coil includes a factory-installed TXV and has an all-aluminum construction. Because the model combination differs from the other 14.5 SEER2 listing, buyers should verify the exact equipment identifiers in any proposal.
Why it was selected: It provides another specific matched-system configuration for side-by-side comparison, rather than assuming that similar headline ratings mean identical components.
Limitation: The product information does not describe an oil boiler or establish fit for any particular home. Verify component matching and sizing before purchase.
Buying Guide: Choosing A Hybrid Heat Pump And Boiler Setup
Is a gas-furnace dual-fuel system the same as a heat pump with an oil boiler?
No. A dual-fuel heat pump system uses a heat pump and a second heating source. The five products above list gas furnaces as that second source. An oil-boiler hybrid uses an oil-fired boiler instead, so these packages do not directly meet a request for a heat pump-and-oil-boiler system. If keeping an existing oil boiler is essential, ask a local HVAC contractor whether it can be integrated with a separately selected heat pump and compatible controls.
How should I compare furnace input and capacity?
Furnace input ratings in this group range from 80,000 to 100,000 BTU. A higher number does not automatically mean better comfort or a better match. The right capacity depends on the home’s heat loss, insulation, climate, ductwork, and other site conditions. Have a qualified professional perform a load calculation instead of choosing solely by floor area or the existing unit’s label.
What does the SEER2 figure tell me?
SEER2 is a cooling-efficiency rating. The listed Goodman ratings apply to complete matched combinations, not each component on its own. The Oxbox listing gives a 14.3 SEER2 heat-pump figure, while the Goodman combinations list 14.5 or 15.2 SEER2 for the matched system. These numbers do not, by themselves, describe heating efficiency in cold weather or predict utility bills.
Why check the matched equipment and AHRI information?
Indoor coils, outdoor heat pumps, and furnaces are selected as combinations. The supplied Goodman details identify AHRI certificates for the stated matched ratings. Compare the exact model numbers on the equipment proposal with the product listing, and confirm that the intended combination is appropriate for the installation. A similar rating or brand name does not prove that two configurations are interchangeable.
What should I ask about controls and changeover?
Ask the installer how the system will switch between heat-pump operation and furnace operation, what temperature or operating conditions trigger the change, and which thermostat or controls are required. The product details establish dual-fuel intent for the listed packages but do not specify a complete control setup or changeover settings. Those details should be confirmed for the home and equipment combination.
What other installation details matter?
Check the indoor equipment orientation, available space, duct connections, electrical requirements, refrigerant requirements, and local permitting needs with the installing contractor. The product details identify some coil orientations and refrigerants, but do not provide a complete site-specific installation plan. Buyers replacing an oil boiler should also ask how domestic hot water, existing hydronic distribution, and any retained heating equipment will be handled.
Frequently Asked Questions
Do these products include an oil boiler?
No. The listed products pair heat pumps with gas furnaces. None of the supplied descriptions identifies an oil-fired boiler.
Can a heat pump work with an existing oil boiler?
It may be possible to design a system around existing equipment, but these product listings do not confirm compatibility with an oil boiler. Ask a qualified HVAC professional to assess the boiler, heat distribution, controls, and proposed heat pump.
Which listed product has the largest heat-pump capacity?
The Oxbox package is listed as a 4-ton system. The four Goodman packages are listed as 2.5-ton systems. Capacity alone does not establish which system is right for a home.
Which Goodman options list 15.2 SEER2?
Two Goodman packages list 15.2 SEER2: the 100,000 BTU furnace combination and the 80,000 BTU furnace combination. Their supplied model numbers and AHRI certificate numbers differ.
Does an 80% AFUE rating mean 80% of the heat pump’s output is retained?
No. AFUE describes the listed gas furnace’s seasonal fuel-use efficiency, not the heat pump’s efficiency. The heat pump and furnace use different performance measures.
Should I buy based on the listed BTU or tonnage alone?
No. Use the ratings to compare product configurations, then have an HVAC professional determine required heating and cooling capacity for the home.
