A gas furnace and air conditioner combo pairs gas heat with central cooling, but the right system depends on your home’s heating and cooling loads, ductwork, and fuel setup. My best overall pick is the Goodman 3-ton R-32 system rated at 15.2 SEER2 with an 80,000 BTU furnace, which stands out among the listed combos for its higher cooling capacity and stated efficiency. For smaller homes, the Goodman 1.5-ton systems offer several furnace and efficiency configurations to compare, while the Albott mini split is a separate ductless option for a single room. The main tradeoffs are capacity, operating efficiency, installation compatibility, and whether a listing includes a complete matched system. Read on for the full breakdown and a guide to choosing a setup that fits your home.

Key Takeaways
- The 3-ton Goodman R-32 combos are the standout options for homes whose cooling loads call for more capacity; their listed 15.2 SEER2 and 80,000 BTU furnace specs distinguish them from the 1.5-ton group.
- The 1.5-ton choices are not interchangeable. Listings range from 13.8 to 15.2 SEER2 and include different furnace capacities, so confirm the exact model combination before comparing.
- Several Goodman listings provide incomplete specifications. Check the full equipment model numbers, furnace input, and included components before treating similarly named systems as equivalent.
- The Albott mini split serves a different need. Its 12,000 BTU, 115V ductless design may suit a room, but it is not a whole-home gas furnace and central AC combo.
- The standalone Goodman furnace is not a complete combo. It may fit a replacement project where cooling equipment is sourced separately, but it cannot meet the same all-in-one equipment need as a matched system listing.

More Details on Our Top Picks
1.5 Ton 13.4 SEER2 Air Conditioner and 80% 40k BTU Natural Gas Furnace System, Upflow
For a smaller home that needs a matched gas furnace and central air system, this ACiQ package pairs 18,000 BTU of cooling with a 40,000 BTU/h furnace input. Its upflow layout suits ductwork configured to send air upward, while the nine-speed ECM blower offers more airflow adjustment than the Goodman 1.5-ton package’s listed multi-speed blower. The tradeoff is cooling efficiency: at 13.4 SEER2, it sits below the Goodman systems rated at 15.2 SEER2, so buyers prioritizing cooling efficiency may prefer those alternatives. The 80% AFUE furnace is also a straightforward rather than high-efficiency heating choice. I would rule it out for California or Colorado projects because the supplied product data says it does not meet those states’ low-NOx rules. Its 73 dB(A) outdoor noise rating and component weights also make placement and professional handling relevant.
Pros:- Matched 1.5-ton cooling and 40,000 BTU/h natural-gas furnace
- Nine-speed ECM blower allows airflow adjustment
- Upflow configuration suits compatible duct systems
- Uses R32 refrigerant
Cons:- 13.4 SEER2 is below the listed 15.2 SEER2 Goodman systems
- Not compliant with California and Colorado low-NOx requirements per product data
- Heavy components call for professional handling
Best for: Owners of smaller homes with upflow ductwork who want a matched natural-gas furnace and central AC system.
Not ideal for: California and Colorado buyers, or homeowners prioritizing higher SEER2 cooling efficiency over a smaller-capacity setup.
- Cooling capacity:18,000 BTU/h (1.5 ton)
- Cooling efficiency:13.4 SEER2
- Furnace input:40,000 BTU/h
- Furnace output:32,000 BTU/h
- Furnace efficiency:80% AFUE
- Refrigerant:R32
- Blower:9-speed ECM
- Electrical:208/230 V, single-phase, 60 Hz
Our verdict“Choose this ACiQ package for a smaller upflow home where matched gas heat and cooling matter more than maximizing SEER2 efficiency.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System, 15.2 SEER2, 80% AFUE, 80,000 BTU
This Goodman is the 1.5-ton pick for buyers who want 15.2 SEER2 cooling and a two-stage, 80,000 BTU/h furnace in one matched split system. Compared with the ACiQ 1.5-ton package, it offers a higher listed cooling-efficiency rating and a two-stage furnace, which can run at a lower heating output when full capacity is unnecessary. That larger furnace input makes proper professional sizing especially important; the tonnage alone does not establish whether it fits a particular home. Its 80% AFUE is the same as ACiQ’s, so the distinction is staging and cooling rating, not a higher furnace-efficiency class. The package includes a cased coil with a factory TXV, but the thermostat, labor, line set, and field accessories are excluded. I would skip it for Colorado installations, where the supplied listing says the furnace is not for sale.
Pros:- 15.2 SEER2 cooling rating
- Two-stage 80,000 BTU/h gas furnace
- Multi-speed ECM blower
- Cased evaporator coil includes a factory-installed TXV
Cons:- 80% AFUE furnace efficiency
- Professional sizing and installation are required
- Thermostat, labor, line set, and field accessories are not included
Best for: Homeowners with a professionally sized smaller home who want a two-stage gas furnace paired with 1.5-ton R-32 cooling.
Not ideal for: Colorado buyers, or anyone expecting the package to include a thermostat, installation labor, line set, and field accessories.
- Cooling capacity:1.5 tons (18,000 BTU)
- Cooling efficiency:15.2 SEER2
- Refrigerant:R-32
- Furnace input:80,000 BTU/h
- Furnace efficiency:80% AFUE
- Heating stages:Two-stage
- Blower:Multi-speed ECM
- System type:Split system
Our verdict“Pick this Goodman when a correctly sized 1.5-ton system with two-stage gas heat and a higher SEER2 rating fits your home and installation plan.”
Goodman 3 Ton 15.2 SEER2 Air Conditioning System with 9-Speed Motor and Free Thermostat
This 3-ton Goodman is an air-conditioning system, not a gas furnace and AC combo. It can be relevant to a roundup buyer who already has compatible gas heat and needs to replace or add cooling, but it does not supply furnace heating. That makes it a different fit from the matched Goodman 3-ton gas furnace package, which includes an 80,000 BTU/h furnace with two-stage heat. The listed 15.2 SEER2 rating and included thermostat help define the cooling package, while the 9-speed motor and remote and touch controls offer several control options. However, the product data lists R-410A, whereas the matched R-32 Goodman systems use a different refrigerant, and compatibility with existing equipment is not specified. I would not choose this as a standalone solution for a buyer seeking both gas heat and central AC.
Pros:- 3-ton cooling capacity
- 15.2 SEER2 listed cooling efficiency
- Thermostat is included
- 9-speed motor with remote and touch controls
Cons:- Does not include a gas furnace or provide gas heating
- Uses R-410A rather than the R-32 listed for the matched Goodman combo systems
- Product data does not specify warranty, noise level, or existing-system compatibility
Best for: Homeowners replacing cooling equipment who already have compatible gas heating and want a 3-ton split AC system with a thermostat included.
Not ideal for: Buyers who need a complete gas furnace and air conditioner combo, or need confirmed compatibility with existing equipment.
- Cooling efficiency:15.2 SEER2
- Refrigerant:R-410A
- System type:Split system
- Compressor type:Rotary-scroll
- Motor:9-speed
- Power:3,500 watts
- Controls:Remote and touch
- Thermostat:Included
Our verdict“Consider this Goodman only if you need cooling equipment for an existing compatible gas-heated home, not a complete furnace-AC combo.”
Albott 12,000 BTU Mini Split Air Conditioner & Heating System with Fast-Fit Set, 115V, 18 SEER2, Ductless Inverter, DIY Install for Bedroom & Living Room
The Albott offers ductless heating and cooling for a room or smaller area, but its heating system is not a gas furnace. That distinction matters in this roundup: unlike the matched Goodman 1.5-ton package, it does not connect central AC to a natural-gas furnace or use existing ductwork. Its 12,000 BTU capacity and 750 sq. ft. stated coverage point to a room-scale use, while the 18 SEER2 rating and inverter design are aimed at varying output rather than serving a whole home. The listed 115 V supply and fast-fit installation approach may appeal where ductwork is absent, but DIY suitability does not remove the need to assess electrical and installation requirements. This is a poor substitute for a central gas combo when multiple rooms need coordinated heating and cooling.
Pros:- Ductless heating and cooling in one system
- 18 SEER2 rating with inverter technology
- 115 V electrical specification
- Listed coverage up to 750 sq. ft. and noise under 29 dB
Cons:- Does not include a gas furnace or connect to central ductwork
- 12,000 BTU capacity is aimed at a limited area
- Power cord is not included and installation still calls for electrical skills
Best for: A homeowner adding ductless heating and cooling to a bedroom, living room, or other area up to the stated 750 sq. ft. coverage.
Not ideal for: Buyers replacing a central gas furnace and AC system or seeking whole-home comfort through existing ducts.
- Capacity:12,000 BTU
- Cooling efficiency:18 SEER2
- Voltage:115 V
- Coverage area:Up to 750 sq. ft.
- Temperature range:5°F–122°F
- Noise level:Under 29 dB
- Warranty:5-year compressor, 8-year parts
- System type:Ductless inverter
Our verdict“Choose the Albott for a ductless room addition where central gas furnace replacement is not the goal.”
Goodman 3-Ton R-32 Air Conditioner and Gas Furnace System, 15.2 SEER2, 80% AFUE, 80,000 BTU
For a home suited to 3-ton central cooling, this Goodman combines 36,000 BTU of AC capacity with an 80,000 BTU/h, two-stage gas furnace. It is the complete matched combo among the two 3-ton Goodman options here; the other 3-ton Goodman listing provides air conditioning but no furnace. The 15.2 SEER2 rating and R-32 refrigerant give this package a more defined efficiency and refrigerant profile than the ACiQ 1.5-ton system, though that smaller unit serves a different capacity range. Its furnace is rated at 80% AFUE, and the condenser is single-stage cooling, so buyers should not mistake two-stage heating for variable-capacity air conditioning. Installation and sizing need professional input, and thermostat, line set, labor, and field accessories are not included. The supplied data also excludes this furnace from sale in Colorado.
Pros:- Matched 3-ton AC and gas furnace package
- 15.2 SEER2 cooling with R-32 refrigerant
- Two-stage 80,000 BTU/h furnace with multi-speed ECM blower
- Cased all-aluminum coil has a factory-installed TXV
Cons:- 80% AFUE furnace efficiency
- Single-stage condenser provides cooling only
- Thermostat, line set, labor, and field accessories are excluded
Best for: Owners of larger homes whose professional load calculation supports 3-ton cooling and who need a matched two-stage gas furnace.
Not ideal for: Smaller homes, Colorado buyers, or purchasers expecting installation materials and labor in the package.
- Cooling capacity:3 tons (36,000 BTU)
- Cooling efficiency:15.2 SEER2
- Refrigerant:R-32
- Furnace input:80,000 BTU/h
- Furnace efficiency:80% AFUE
- Heating stages:Two-stage
- Condenser operation:Single-stage, cooling-only
- Warranty:10-year limited parts warranty with qualifying installation and registration
Our verdict“Choose this Goodman when a professional confirms that your larger home needs 3-ton cooling and the included two-stage gas furnace.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System
For a 1.5-ton system with a larger furnace input, this matched Goodman package pairs 15.2 SEER2 cooling with an 80,000 BTU/h, two-stage gas furnace. Compared with the Goodman 60,000 BTU/h two-stage system, it offers more heating input, which may suit a home whose heating load calls for it; the right capacity still depends on a professional load calculation. The multi-speed ECM blower and cased coil with a factory-installed TXV round out the matched equipment. Its tradeoff is a single-stage, cooling-only condenser, so the two-stage heat does not mean staged cooling. I’d shortlist it when the furnace capacity and upflow/downflow coil fit the project, but skip it if the home needs lower heating input or Colorado availability.
Pros:- Matched condenser, evaporator coil, and gas furnace package
- Two-stage heating can better match changing heating demand than a single-stage furnace
- Multi-speed ECM blower
- Factory-installed TXV on the cased evaporator coil
Cons:- 80,000 BTU/h input may be more than a smaller home needs; sizing requires a load calculation
- Cooling remains single-stage
- Thermostat, labor, line set, and field accessories are not included
Best for: Owners replacing a 1.5-ton split system whose professional load calculation supports an 80,000 BTU/h furnace and two-stage heat
Not ideal for: Colorado buyers or homeowners whose heating load calls for a smaller furnace or whose installation layout does not fit the cased coil
- System type:Split air conditioner and gas furnace
- Cooling capacity:1.5 tons (18,000 BTU)
- Cooling efficiency:15.2 SEER2
- Furnace input and efficiency:80,000 BTU/h; 80% AFUE
- Heating stages:Two-stage
- Blower:Multi-speed ECM
- Refrigerant:R-32
- Evaporator coil:Cased upflow/downflow; factory-installed TXV
Our verdict“Choose this package when a contractor confirms that your 1.5-ton cooling system and home need its 80,000 BTU/h, two-stage furnace.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System, 13.8 SEER2, 40,000 BTU
This is the lower-input choice among the 1.5-ton systems here: its furnace is rated at 40,000 BTU/h and 80% AFUE, while cooling is rated at 13.8 SEER2. Compared with the 15.2 SEER2 Goodman packages, it gives up cooling efficiency; compared with the 60,000 and 80,000 BTU/h options, it provides less furnace input. That makes it a candidate for a smaller heating load, not a shortcut around proper sizing. Both heating and cooling are single-stage, while the multi-speed ECM blower adds airflow flexibility. The matched R-32 condenser, coil, and furnace simplify equipment selection, but sale is restricted in listed locations, and the thermostat, installation labor, line set, and accessories are separate.
Pros:- Matched condenser, coil, and gas furnace package
- Lower 40,000 BTU/h furnace input than the 60,000 and 80,000 BTU/h options
- Multi-speed ECM blower
- R-32 refrigerant
Cons:- 13.8 SEER2 is below the 14.5 and 15.2 SEER2 Goodman alternatives listed
- Single-stage heating and cooling
- Sale is restricted in specified states, the District of Columbia, and U.S. territories
Best for: Owners of smaller homes or well-insulated spaces whose contractor confirms that 40,000 BTU/h furnace input and 1.5-ton cooling suit the load
Not ideal for: Buyers seeking higher SEER2 cooling, two-stage heating, or a system available in restricted states and territories
- System type:Split air conditioner and gas furnace
- Cooling capacity:1.5 tons (18,000 BTU)
- Cooling efficiency:13.8 SEER2
- Furnace input and efficiency:40,000 BTU/h; 80% AFUE
- Heating stages:Single-stage
- Cooling stages:Single-stage
- Blower:Multi-speed ECM
- Refrigerant:R-32
Our verdict“Consider this system for a professionally sized, lower-load home where the 40,000 BTU/h furnace fits and its lower cooling efficiency is acceptable.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System
The variable-speed ECM blower is the defining difference in this 1.5-ton Goodman package. It pairs with two-stage, 60,000 BTU/h heating and 15.2 SEER2 cooling, putting this model between the 40,000 and 80,000 BTU/h furnace options in the lineup. Compared with the 60,000 BTU/h Goodman that uses a multi-speed blower and single-stage heat, this system offers variable-speed airflow and two-stage heating; that added flexibility may help the system respond more gradually, depending on installation and controls. Cooling is still single-stage, so it is not a fully staged heating-and-cooling setup. The horizontal cased coil suits compatible layouts, but buyers needing upflow/downflow orientation should compare the other matched packages. Professional sizing and installation are required.
Pros:- Variable-speed ECM blower
- Two-stage heating at 60,000 BTU/h input
- 15.2 SEER2 cooling rating
- All-aluminum cased horizontal coil with factory-installed TXV
Cons:- Cooling condenser is single-stage
- Horizontal coil orientation may not fit other duct layouts
- Thermostat, labor, line set, and field accessories are not included
Best for: Homeowners with a compatible horizontal installation who want 60,000 BTU/h two-stage heat and a variable-speed ECM blower
Not ideal for: Buyers needing an upflow/downflow coil, Colorado availability, or staged cooling
- System type:Split air conditioner and gas furnace
- Cooling capacity:1.5 tons (18,000 BTU)
- Cooling efficiency:15.2 SEER2
- Furnace input and efficiency:60,000 BTU/h; 80% AFUE
- Heating stages:Two-stage
- Blower:Variable-speed ECM
- Evaporator coil:Cased horizontal, all-aluminum, factory-installed TXV
- Refrigerant:R-32
Our verdict“Pick this model when variable-speed airflow and two-stage heat matter and your duct setup accepts its horizontal coil.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System
This package balances 15.2 SEER2 cooling with 60,000 BTU/h of furnace input, but its single-stage heat keeps the setup simpler than the two-stage 60,000 BTU/h Goodman. Both use multi-speed ECM blowers, while the other model adds a second heating stage and a variable-speed blower. That difference may matter to buyers who want more gradual heating operation; this one is the more basic match if single-stage heat suits the home and controls. Its cased upflow/downflow coil includes a factory-installed TXV, making it a flexible fit for compatible duct orientations. The single-stage condenser means cooling operation also stays straightforward. Professional sizing is essential, and the system does not include the thermostat, labor, line set, or field accessories.
Pros:- Matched condenser, coil, and furnace package
- 15.2 SEER2 cooling with R-32 refrigerant
- Multi-speed ECM blower
- Cased upflow/downflow coil with factory-installed TXV
Cons:- Single-stage heating offers less staging flexibility than the two-stage 60,000 BTU/h alternative

- Thermostat, labor, line set, and field accessories are additional
Best for: Homeowners replacing a compatible upflow/downflow split system who want 15.2 SEER2 cooling, 60,000 BTU/h input, and single-stage heat
Not ideal for: Buyers who want two-stage heating or variable-speed airflow, or buyers in Colorado
- System type:Split air conditioner and gas furnace
- Cooling capacity:1.5 tons (18,000 BTU)
- Cooling efficiency:15.2 SEER2
- Furnace input and efficiency:60,000 BTU/h; 80% AFUE
- Heating stages:Single-stage
- Blower:Multi-speed ECM
- Evaporator coil:Cased upflow/downflow with factory-installed TXV
- Refrigerant:R-32
Our verdict“Choose this model for a compatible duct layout and a straightforward 60,000 BTU/h, single-stage heating setup.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System, 14.5 SEER2, 80% AFUE, 40,000 BTU
This 40,000 BTU/h option raises cooling efficiency to 14.5 SEER2, placing it between the 13.8 and 15.2 SEER2 Goodman systems in this group. Like the 13.8 SEER2 model, it has single-stage heating and a multi-speed ECM blower, but it offers a higher listed cooling rating. The furnace remains at 80% AFUE, so the efficiency distinction here is on the air-conditioning side. Its all-aluminum upflow/downflow coil has a factory-installed TXV, giving it a flexible orientation for compatible installations. Compared with the two-stage 60,000 BTU/h models, this is a lower-input, single-stage heating choice; it may suit a smaller heating load, but only a contractor’s load calculation can establish fit. The thermostat, line set, labor, and field accessories are not included.
Pros:- 14.5 SEER2 cooling exceeds the 13.8 SEER2 40,000 BTU/h alternative
- 40,000 BTU/h furnace input for a lower heating load
- Multi-speed ECM blower
- All-aluminum upflow/downflow coil with factory-installed TXV
Cons:- Single-stage heating
- Cooling efficiency is below the 15.2 SEER2 options
- Thermostat, line set, labor, and field accessories are not included
Best for: Owners whose load calculation supports 40,000 BTU/h input and who want a higher SEER2 rating than the 13.8 SEER2 1.5-ton option
Not ideal for: Homes needing more than 40,000 BTU/h furnace input or buyers seeking two-stage heating and Colorado availability
- System type:Split air conditioner and gas furnace
- Cooling capacity:1.5 tons (18,000 BTU)
- Cooling efficiency:14.5 SEER2
- Furnace input and efficiency:40,000 BTU/h; 80% AFUE
- Heating stages:Single-stage
- Blower:Multi-speed ECM
- Evaporator coil:Cased upflow/downflow, all-aluminum, factory-installed TXV
- Refrigerant:R-32
Our verdict“This is a suitable shortlist option when your home needs a 40,000 BTU/h furnace and you prefer 14.5 SEER2 cooling over the lower-rated alternative.”
Goodman 1.5-Ton R-32 Air Conditioner and Gas Furnace System
For a smaller home or zone, this matched 1.5-ton system pairs 18,000 BTU of cooling with a 40,000 BTU/h gas furnace. Its 15.2 SEER2 rating and R-32 refrigerant make it a more efficient cooling choice on paper than the roundup’s 1.5-ton 13.4 SEER2 system. The factory-installed TXV coil and multi-speed ECM blower add useful compatibility and airflow control within the matched package.
The tradeoff is single-stage operation: it has fewer ways to adjust output than a variable-capacity system. At 75 dB, the condenser also merits attention when choosing its location. Like the 3-ton Goodman system, it needs professional sizing and installation; its smaller capacity suits a different load, not a lower-cost shortcut for an undersized home. The furnace is unavailable for sale in Colorado.
Pros:- Matched 1.5-ton condenser, coil, and gas furnace simplify equipment coordination.
- 15.2 SEER2 cooling rating exceeds the roundup’s 13.4 SEER2 1.5-ton system.
- R-32 refrigerant and factory-installed TXV coil.
- Multi-speed ECM blower supports more airflow adjustment than a basic fixed-speed blower.
Cons:- Single-stage cooling offers limited output adjustment.

Goodman 3-Ton R-32 Air Conditioner and Gas Furnace System, 15.2 SEER2, 80,000 BTU
More cooling and heating capacity set this matched Goodman package apart from the 1.5-ton systems in the roundup: it provides 36,000 BTU of cooling and an 80,000 BTU/h furnace input. That makes it a candidate for larger homes, provided a contractor’s load calculation supports that size. Its 15.2 SEER2 cooling, R-32 refrigerant, cased coil with factory-installed TXV, and multi-speed ECM blower round out a coordinated split system.
Compared with the smaller Goodman 1.5-Ton R-32 system, this unit serves a greater load but may be oversized for a compact or efficient home. Cooling and heating are single-stage, so it lacks the finer output adjustment of staged equipment. Professional installation is required, and labor, thermostat, line set, and field accessories are not included. The furnace is also unavailable for sale in Colorado.
Pros:- Matched 3-ton cooling and 80,000 BTU/h furnace suit a larger calculated load.
- 15.2 SEER2 cooling rating with R-32 refrigerant.
- Cased coil includes a factory-installed TXV.
- Multi-speed ECM blower offers airflow flexibility.
Cons:- Single-stage heating and cooling provide limited output adjustment.
- Labor, thermostat, line set, and field accessories are not included.
- Professional sizing and installation are required; furnace is not for sale in Colorado.
Best for: Owners of larger homes whose contractor confirms a 3-ton cooling load and who need a matched gas furnace and central air system.
Not ideal for: Owners of small or highly efficient homes that need less capacity, and buyers seeking a turnkey installation package or shopping in Colorado.
- Cooling capacity:3 tons (36,000 BTU)
- Cooling efficiency:15.2 SEER2
- Furnace input:80,000 BTU/h
- Furnace efficiency:80% AFUE
- Refrigerant:R-32

Our verdict“Pick this 3-ton Goodman for a larger home only when a contractor confirms its capacity fits your heating and cooling loads.”
Goodman 100,000 BTU 80% Efficiency Multi-Speed Single-Stage Upflow/Horizontal Furnace Model GR9S801005CN
This is a furnace, not a complete air conditioner and gas furnace combo. Its 100,000 BTU capacity and upflow or horizontal configuration may suit a replacement project where the existing cooling equipment will stay in place. That makes it a different kind of choice from the complete Goodman 1.5-Ton R-32 system, which includes a condenser and evaporator coil as well as the furnace.
The stainless steel heat exchanger and stated 10-year parts and unit replacement coverage are useful features, subject to proper installation and registration. But the 80% efficiency rating and single-stage operation are straightforward rather than high-efficiency or finely modulated. At 175 pounds, it also needs careful handling. Check orientation before buying: downflow installation is not supported, and accessories are sold separately.
Pros:- 100,000 BTU capacity for homes with a matching heating load.
- Upflow and horizontal installation options.
- Stainless steel heat exchanger.
- Listed 10-year parts and unit replacement warranty when installed and registered properly.
Cons:- Furnace only; no air conditioner or evaporator coil is included.
- Cannot be installed in a downflow configuration.
- Heavy at 175 pounds, and accessories are sold separately.
Best for: Homeowners replacing an existing furnace in an upflow or horizontal setup while retaining compatible central cooling equipment.
Not ideal for: Buyers seeking a complete gas furnace and air conditioner package, needing downflow installation, or looking for a higher-efficiency furnace.
- Model:GR9S801005CN
- Capacity:100,000 BTU
- Efficiency:80%
- Installation orientation:Upflow or horizontal; not downflow
- Weight:175 pounds
- Dimensions:28 x 21 x 34 inches
- Voltage:115 volts
- Noise level:56 dB
Our verdict“Choose this furnace for a compatible upflow or horizontal replacement when you plan to keep existing cooling equipment.”
Goodman 1.5 Ton 15.2 SEER2 80% AFUE 40,000 BTU R-32 Air Conditioner & Gas Furnace System
This Goodman bundles a 1.5-ton R-32 air conditioner, cased coil, and 40,000 BTU/h gas furnace into one matched split system. Its 15.2 SEER2 cooling rating and 80% AFUE heating rating give buyers clear efficiency figures for both sides of the combination. Compared with the Goodman 3-Ton R-32 system, this package provides half the cooling capacity, making it a better candidate for a smaller calculated load rather than a larger home.
The multi-speed ECM blower allows more airflow adjustment than a simple fixed-speed setup, but the system remains single-stage according to the matching model information. That limits how closely it can match changing demand. It also requires professional sizing and installation; thermostat, line set, and field accessories are not included. The furnace is not for sale in Colorado, so availability can rule it out regardless of fit.
Pros:- Includes matched condenser, evaporator coil, and gas furnace.
- 15.2 SEER2 cooling and 80% AFUE heating ratings.
- R-32 refrigerant and multi-speed ECM blower.
- 1.5-ton capacity offers a smaller-system alternative to the roundup’s 3-ton Goodman package.
Cons:- Single-stage operation has limited ability to adjust output to changing demand.
- Professional sizing and installation are mandatory.
- Thermostat, line set, and field accessories are not included; furnace is unavailable in Colorado.
Best for: Owners of smaller homes replacing both central cooling and gas heating who want one matched 1.5-ton equipment package.
Not ideal for: Owners who need greater than 1.5-ton cooling capacity, want a staged system, or are buying in Colorado.
- Cooling capacity:1.5 tons (18,000 BTU)
- Heating input:40,000 BTU/h
- Cooling efficiency:15.2 SEER2
- Heating efficiency:80% AFUE
- Refrigerant:R-32
- Blower:Multi-speed ECM
- Voltage:208 V
- Installation:Split system; professional installation required
Our verdict“This package fits a smaller home with a verified 1.5-ton load when you want a matched R-32 air conditioner and gas furnace.”
How We Picked
I compared the listed products against the needs implied by a gas furnace and air conditioner combo: matched heating and central cooling, stated capacity, efficiency information, and the clarity of the equipment configuration. I gave more weight to entries that identify both the air conditioner and gas furnace and provide usable specifications, since buyers need those details to assess fit and compare likely operating tradeoffs. I also treated the 1.5-ton and 3-ton systems as options for different load requirements rather than assuming one capacity suits every home.
The ranking favors complete system listings with clearer specifications and stronger stated cooling efficiency, while accounting for meaningful limitations. Similar Goodman listings remain distinct only where their stated capacity or efficiency differs; sparse listings are harder to judge and require more confirmation from the seller or installer. The mini split and standalone furnace are included as adjacent alternatives, but rank behind complete central combos for a buyer specifically seeking a gas furnace and central air conditioner package.

Factors to Consider When Choosing Gas Furnace Air Conditioner Combo
Choosing a combo starts with your home’s requirements, then moves to equipment details and installation constraints. I would use the following checks to narrow the field before comparing model names or headline specifications.
Match capacity to a professional load calculation
Air conditioner tonnage and furnace output should match the home’s heating and cooling loads, which depend on climate, insulation, windows, air leakage, and layout. A 3-ton system is not automatically a better upgrade from a 1.5-ton model; an oversized AC can cool quickly without running long enough to manage indoor humidity well. An undersized furnace may struggle during cold weather, while excess furnace capacity can lead to frequent cycling. Ask an HVAC contractor to perform a room-by-room load calculation before selecting equipment. Use the result to compare suitable systems in this lineup rather than letting an existing unit’s capacity decide for you. A major change to windows, insulation, or additions can make the old system size a poor reference.
Read efficiency labels in context
SEER2 describes seasonal cooling efficiency, while AFUE describes how much fuel a furnace converts to heat over a season. The listed systems include different SEER2 figures, but many furnace listings state 80% AFUE, so the comparison is not just about a single efficiency number. Higher cooling efficiency can matter more in homes with long, hot cooling seasons, while heating costs depend on local gas rates, climate, and furnace use. Compare equipment with the same capacity and configuration where possible, since different sizes may not share identical performance. Ask for the full product data sheet and verify that the quoted numbers apply to the exact indoor and outdoor units being installed. Consider expected use over the system’s service life, rather than choosing solely by the highest label figure.
Verify that the equipment is a matched system
A product title can omit model details that determine whether the indoor furnace and outdoor AC are approved to operate as a matched combination. Request the exact model numbers for both units and have the installer verify compatibility using manufacturer documentation. Check whether the listing includes a coil, thermostat, line-set components, and any other parts required for the planned installation. A furnace-only listing, such as the 100,000 BTU Goodman model here, needs separate cooling equipment to become a combo. Likewise, don’t assume two similarly titled Goodman listings contain identical components. Resolving these details before purchase can prevent a gap between what the equipment package includes and what the installation requires.
Check fuel, electrical, venting, and duct constraints
A gas furnace needs an appropriate gas supply, venting arrangement, condensate handling where applicable, and electrical connections that meet local requirements. The AC side also needs compatible refrigerant lines, a suitable indoor coil, and ductwork that can move the required airflow. These site conditions can rule out an otherwise attractive system or add substantial work to an installation. Have an installer inspect the existing furnace location, vent route, electrical service, and duct condition before ordering. Confirm whether the listed furnace configuration is upflow, horizontal, or another orientation that fits the space. A ductless mini split may help condition one room, but it does not replace the central ducted system function of a gas furnace and AC combo.
Compare total installed scope, not just equipment labels
Equipment listings do not always describe the full work required to put a system into service. Installation may involve removing old equipment, adapting ducts or venting, electrical changes, refrigerant line work, a thermostat, permits, and startup checks. Ask contractors to specify the equipment model numbers, included components, labor, and any site work in the written scope. This makes it easier to compare proposals that may use different combinations or leave different tasks to the homeowner. A system with a stronger efficiency rating may be a sensible choice for a high-use home, but the benefit depends on climate, energy rates, and correct installation. Treat unusually sparse product details as a reason to obtain clarification before committing.
Frequently Asked Questions
Can I choose between a 1.5-ton and 3-ton system based on my current unit?
Your current unit can provide a starting point, but its size alone does not show what your home needs. Changes to insulation, windows, air leakage, or room use may have changed the heating and cooling loads. Ask an HVAC professional for a load calculation and compare the result with the capacity of each system. An oversized air conditioner can affect humidity control and comfort, even when it cools the home quickly. Use the calculated load to narrow the options before choosing among the 1.5-ton and 3-ton listings.
What should I confirm when two Goodman combo listings look nearly identical?
Compare the exact model numbers for the outdoor AC, furnace, and indoor coil rather than relying on a shortened product title. Confirm cooling capacity, SEER2, furnace input capacity, AFUE, and the furnace orientation. Ask whether the package includes a thermostat and the components needed to make the equipment a matched system. Similar names in this roundup do not always provide the same level of detail, so request the manufacturer’s specification sheets for the exact units. Have your installer verify compatibility and fit before purchase.
Does an 80% AFUE furnace make sense if I am comparing higher-efficiency heating options?
An 80% AFUE rating means the furnace converts a stated portion of its fuel into seasonal heat, but whether that configuration suits you depends on climate, gas costs, home use, and installation constraints. Compare the expected heating demand and local fuel costs with the available furnace options, rather than relying on AFUE alone. Venting requirements and the existing installation can also affect what equipment fits the project. Ask contractors to explain the full installed configuration and any code requirements that apply to your home. This roundup includes several 80% AFUE systems, so check the exact furnace specification for each listing.
Can the Albott mini split replace a gas furnace and central air conditioner?
The Albott listing describes a 12,000 BTU ductless mini split, which serves a different role from a whole-home gas furnace and central AC system. It may suit a room or other limited area where a ductless setup is appropriate, but the listing does not describe a gas furnace. A mini split’s capacity and coverage should be matched to the space it will condition, and it will not use existing central ducts in the same way as a central AC. If you need heating and cooling for the whole home through a central system, compare complete matched furnace and AC packages. Treat the Albott as an alternative for a specific zone, not as an equivalent combo.
What details should I get in writing before ordering a combo online?
Get the exact model numbers for every included unit and a clear list of components in the package. Confirm that the furnace and AC are compatible, and have your installer verify that the capacity, orientation, fuel type, venting, and electrical requirements suit your home. Ask who handles permits, installation, startup, and any duct or line-set changes. Clarify warranty terms and who is responsible for support if a component arrives damaged or does not match the stated package. Written details help you compare the equipment listing with the installation plan before delivery.
Conclusion
For a home with a load that suits its capacity, my best overall choice is the Goodman 3-ton R-32 combo listed at 15.2 SEER2 with an 80,000 BTU furnace, thanks to its clearer, higher-capacity specification. My best value pick is the Goodman 1.5-ton R-32 system listed at 13.8 SEER2 and 40,000 BTU for buyers whose load calculation supports that size and who prioritize a clearly stated configuration. The best premium fit is the 1.5-ton Goodman rated at 15.2 SEER2 for a smaller home where the matched system suits the load; compare its complete model details before deciding. For a beginner, I would start with a clearly specified complete combo and ask an installer to verify the match, rather than trying to piece together the standalone furnace. For a single room or zone, the Albott mini split may fit a ductless project, while the Goodman 100,000 BTU furnace is a specific furnace replacement option that needs separate cooling equipment. Choose by measured home requirements and verified system compatibility, then use the product specifications to make the final comparison.
