If you’re searching for the best R290 heat pumps in 2026, the market has largely shifted toward next-generation low-GWP refrigerants, and the strongest options right now split into two camps: packaged units and split systems. The Goodman 3-Ton 15.2 SEER2 Multi-Position R-32 Heat Pump System (GLZS4BA3610 + AMST42CU1300) stands out as my best overall pick because it pairs the highest efficiency rating in this lineup with a flexible multi-position air handler. For single-room or addition applications, the Daikin 24,000 BTU Entra R32 mini split is the strongest alternative thanks to its 18 SEER2 rating and simpler installation path, while the Ace Air 3.5 Ton packaged unit makes the most sense for buyers who want everything in one cabinet with an included heat kit. The main tradeoff you’ll face is efficiency versus installation simplicity: high-SEER2 split systems cost more to install but run cheaper, while packaged units trade some efficiency for a faster, all-in-one retrofit. Keep reading for the full breakdown of all twelve models and which buyer each one actually suits.

Key Takeaways
- The 15.2 SEER2 Goodman R-32 split systems (picks 2, 8, and 9) clearly outclass the 13.4 SEER2 packaged units on efficiency, but they require ductwork and a more involved installation, which is why they don’t win for every buyer.
- Every Ace Air and Goodman packaged unit in this lineup lands at exactly 13.4 SEER2 — the real differentiators are tonnage (2.5 to 3.5 tons), horizontal versus standard configuration, and the included 10kW heat kit, not efficiency.
- The Daikin Entra R32 mini splits (picks 5 and 11) are the only ductless options here, making them the default choice for garages, additions, and rooms without existing ducts — at 18 SEER2 they’re also the most efficient models in the roundup.
- Goodman‘s 14.3 SEER2 systems (picks 6 and 12) sit in a middle zone: meaningfully more efficient than the packaged units but cheaper to install than the 15.2 SEER2 flagship systems, which makes them the sweet spot for whole-home replacements on a budget.
- Heat kits matter more than most buyers expect — three of the twelve models include a 10kW electric heat kit, which saves a separate purchase and simplifies cold-climate backup heating on packaged installations.

More Details on Our Top Picks
Goodman 2.5 Ton 13.4 SEER2 Packaged Heat Pump (GPHH33031)
This Goodman packaged unit earns its spot as the simplest entry point in the lineup for buyers who want one box that does everything. Because the condenser, coil, and blower ship in a single cabinet, there is no matching an air handler the way the Goodman GLZS4BA3010 split system requires — installation is a single-pad job for an HVAC pro. The tradeoff is efficiency: at 13.4 SEER2, it falls well short of the 15.2 SEER2 split Goodman systems elsewhere in this roundup, so expect higher seasonal operating costs. Compared with the Ace Air 3.5 Ton packaged unit, this model also omits an electric heat kit, which means colder regions will need to add one separately. This pick makes the most sense for warm-climate homeowners replacing an existing packaged unit where ductwork already terminates outdoors.
Pros:- All-in-one packaged design simplifies installation versus split systems
- R-32 refrigerant with lower environmental impact than older R-410A
- Versatile enough for both residential and light commercial applications
- Goodman’s established parts availability makes long-term service easier
Cons:- 13.4 SEER2 is the lowest efficiency tier in this lineup
- No heat kit included, adding cost for cold-climate buyers
Best for: Homeowners in mild climates replacing an aging packaged unit who want straightforward single-cabinet installation
Not ideal for: Buyers in freezing climates — no included heat kit means supplemental electric heat must be purchased separately
- Capacity:2.5 Tons
- SEER2:13.4
- Refrigerant:R-32
- Model:GPHH33031
- Type:Packaged Heat Pump
- Application:Residential and light commercial
Our verdict“A no-frills packaged replacement for mild-climate homes, provided you accept the lowest efficiency rating here.”
Goodman 2.5 Ton 15.2 SEER2 Multi-Position R-32 Heat Pump System with Air Handler (GLZS4BA3010 + AMST42CU1300)
This complete split system is where efficiency and value meet in this roundup. At 15.2 SEER2, it outperforms every packaged unit here — including the Goodman 3 Ton 36K BTU package at 13.4 SEER2 — which translates into noticeably lower monthly cooling bills over a 10–15 year lifespan. Unlike the single-cabinet options, it pairs the GLZS4BA3010 condenser with a multi-position air handler, giving installers flexibility on duct orientation that packaged units can’t match. The 10-year parts warranty sweetens the deal, though it hinges on professional installation and registration within 60 days — skip that step and coverage shrinks. Two caveats: the single-stage compressor holds temperature less precisely than the Daikin Entra’s inverter drive, and the 77 dB rating is louder than a mini-split. Budget for an HKTS heat kit if winters dip below freezing.
Pros:- 15.2 SEER2 is among the highest efficiency ratings in this lineup
- Complete matched system — condenser and air handler included
- Multi-position air handler fits varied ductwork layouts
- 10-year parts limited warranty with qualified installation
Cons:- Heat kit sold separately for sub-freezing climates
- Single-stage compressor gives coarser temperature control than inverter models
Best for: Homeowners with existing ductwork who want split-system efficiency and warranty coverage at a mid-tier price
Not ideal for: Cold-climate buyers unwilling to add the separately sold heat kit, or anyone wanting whisper-quiet inverter operation
- Cooling Capacity:2.5 Ton (30,000 BTU)
- SEER2:15.2
- Refrigerant:R-32
- Compressor Type:Rotary/Scroll, single-stage
- Blower Motor:Multi-speed
- Installation Type:Split System
- Warranty:10-year parts limited (with registration)
Our verdict“The smart middle ground for ducted homes that want packaged-unit convenience beaten on efficiency without paying for inverter tech.”
Goodman 3 Ton 36K BTU Heat Pump Package HVAC Unit, 13.4 SEER2, R-32 Refrigerant
When a 2.5-ton unit won’t cut it, this 3-ton packaged heat pump steps up with the capacity larger homes and small commercial spaces demand. Its standout feature is the two-stage scroll compressor — unlike the single-stage Goodman GLZS4BA3010 split system, it can run at partial load, which means gentler temperature swings and quieter low-speed operation. The multi-speed ECM blower reinforces that comfort advantage over fixed-speed packaged rivals. Build quality is solid, with an all-aluminum evaporator coil and louvered coil protection inside a powder-coated galvanized cabinet. The compromises are real, though: 13.4 SEER2 lags the split Goodmans by a wide margin, and 78 dB is loud enough to matter near patios or bedrooms. It also lacks inverter modulation, so it can’t match the Daikin Entra’s efficiency curve.
Pros:- Two-stage compressor delivers better humidity control and comfort than single-stage units
- 3-ton capacity handles larger spaces than the 2.5-ton models
- Durable all-aluminum coil and louvered coil protection
- Factory-charged for faster, cleaner installation
Cons:- Not an inverter system, limiting efficiency at partial loads
- 78 dB noise level is the loudest in this roundup
Best for: Owners of larger homes or small commercial spaces needing 36K BTU capacity with two-stage comfort in one cabinet
Not ideal for: Buyers prioritizing efficiency or quiet — 13.4 SEER2 and 78 dB trail the split and mini-split options here
- Cooling Capacity:36,000 BTU (3 tons)
- SEER2:13.4
- HSPF2:6.7
- Refrigerant:R-32
- Compressor:Two-stage scroll
- Blower:Multi-speed ECM
- Installation:Packaged, horizontal discharge
- Warranty:10-year parts limited
Our verdict“The capacity-and-comfort pick for big ducted spaces, as long as efficiency isn’t your top priority.”
Ace Air 3.5 Ton 13.4 SEER2 Horizontal Heat Pump Package Unit with 10kW Electric Heat Kit
This Ace Air unit solves the problem most packaged units in this roundup create: it ships with a built-in 10kW electric heat kit, so buyers in colder regions don’t face the extra purchase that the Goodman GPHH33031 and Goodman split systems demand. With 3.5 tons of capacity, it also out-muscles every other product here, making it the go-to for larger homes or light commercial jobs where winter backup heat is non-negotiable. The multi-speed ECM blower keeps operation quieter than fixed-blower packaged units, and the all-aluminum coil plus galvanized cabinet should hold up outdoors for years. Compared with the Goodman 3-ton package, you give up the two-stage compressor — this is a single-stage comfort level — and horizontal-only discharge restricts placement. At 390 pounds, plan on a crew and a crane or pad-ready site.
Pros:- 10kW electric heat kit included — no separate cold-climate purchase needed
- 3.5-ton capacity is the largest in this lineup
- Quiet multi-speed ECM blower operation
- Durable all-aluminum coils in a galvanized steel cabinet
Cons:- 390-pound unit requires professional rigging and installation
- Horizontal design restricts placement versus multi-position alternatives
Best for: Cold-climate homeowners or small businesses needing high capacity with integrated backup electric heat in one delivery
Not ideal for: Homes with tight or vertical-only installation spots — the horizontal-only design and 390-pound weight limit flexibility
- Capacity:3.5 Ton / 42,000 BTU
- SEER2:13.4
- Refrigerant:R-32
- Heat Kit:10kW electric heat strip (included)
- Voltage:208/230V, 1-phase, 60Hz
- Dimensions:66″ D x 35″ W x 34″ H
- Warranty:10-year parts limited
Our verdict“The packaged choice for buyers who refuse to buy a heat kit separately and need maximum capacity.”
Daikin 24,000 BTU 18 SEER2 Entra R32 Series Heat Pump Mini Split A/C
The Daikin Entra plays a completely different game from everything else here. With 18 SEER2 and DC inverter technology, it is by far the most efficient option in this roundup — the modulating compressor ramps up and down instead of cycling on and off, so it beats the 15.2 SEER2 Goodman split on both energy use and temperature stability. It also covers spaces up to 1,500 sq. ft. without any ductwork, which no packaged or split system can do, and it heats down to 5°F outdoor, making it viable where the ducted units lean on electric backup heat. Unlike the Goodman packages, it arrives with a 25-foot line set kit, bracket, and remote. Tradeoffs: the 24,000 BTU output suits a single large zone rather than a whole ducted house, and professional installation is mandatory for refrigerant handling.
Pros:- 18 SEER2 with DC inverter is the highest efficiency in this roundup
- Heats effectively down to 5°F outdoor temperature
- Requires no ductwork — ideal for additions and conversions
- Includes line set kit, wall bracket, and photocatalytic air purification filter
Cons:- Single-zone design can’t replace whole-house ducted systems
- Heating output drops off above 65°F outdoor temperature in heat mode
Best for: Homeowners adding climate control to a large room, addition, or ductless conversion who want inverter efficiency
Not ideal for: Whole-house buyers with existing ductwork — a single-zone mini-split can’t distribute air like the Goodman split systems
- Cooling Capacity:24,000 BTU (6,900–24,200 modulation)
- Heating Capacity:23,000 BTU (5,800–27,300 modulation)
- SEER2:18
- COP:3.30
- Coverage Area:Up to 1,500 sq. ft.
- Refrigerant:R-32
- Heating Operating Range:5°F to 65°F
- Included:Indoor unit, condenser, remote, 25 ft line set, wall bracket
Our verdict“The pick for ductless spaces where inverter efficiency and precise comfort matter more than whole-house air distribution.”
Goodman 2.5 Ton 14.3 SEER2 R-32 Heat Pump Split System with Non-Programmable Thermostat
This Goodman package covers the essentials well: a 2.5-ton single-stage heat pump, a multi-position air handler with a 9-speed ECM blower, and a thermostat in the box. Compared with the Goodman 3-Ton 15.2 SEER2 system (GLZS4BA3610), this one gives up about a point of SEER2 efficiency, which translates into modestly higher running costs over a full season — but it costs less upfront and the smaller capacity suits homes that don’t need 36K BTU. The tradeoffs are real, though: the heat kit is sold separately, so buyers in colder regions need to budget for it, and the single-stage compressor runs full-blast or not at all, unlike inverter-driven mini splits such as the Daikin Entra series. The 10-year parts warranty depends on qualified installation and registration within 60 days.
Pros:- 9-speed ECM blower delivers consistent, efficient airflow across the house
- Multi-position air handler supports upflow and horizontal installations for flexible placement
- Includes a digital non-programmable thermostat so the system is usable out of the box
- 10-year parts warranty with qualified installation
Cons:- Heat kit sold separately and practically required in colder regions
- Single-stage operation means larger temperature swings and no capacity modulation
- Downflow installation requires an optional kit purchased separately
Best for: Homeowners with a 1,200–1,800 sq ft home in mild climates who want a complete split system at a lower entry price
Not ideal for: Cold-climate buyers — without the separately sold heat kit, heating performance drops off when temperatures fall
- Cooling Capacity:2.5 tons
- Refrigerant:R-32
- Blower Motor:9-speed ECM, direct-drive
- Voltage:240 volts
- Configuration:Upflow, horizontal left, horizontal right
- Warranty:10-year parts with qualified installation and registration
Our verdict“A sensible mid-size split system for mild-climate homeowners who value low upfront cost over maximum efficiency.”
ACE AIR GPHH3 Series 3 Ton Horizontal Heat Pump Package Unit with 10kW Heat Kit
The Ace Air GPHH3 solves the biggest frustration with the Goodman split systems in this lineup: everything is in one cabinet, and the 10kW heat strip is included rather than a separate purchase. That makes this 3-ton unit a strong match for colder areas where auxiliary electric heat is not optional. Efficiency lands at 13.4 SEER2 — lower than the Goodman 3-Ton 15.2 SEER2 split system — so buyers trade some year-round operating economy for simplicity and cold-weather readiness. The galvanized steel cabinet with louvered coil protection and multi-speed ECM blower suit rooftop or ground-level installs, and there’s no lineset, refrigerant charging, or indoor air handler to coordinate. The catch is weight and logistics: at 370 lbs, this requires a crane or crew for most rooftop placements, and the warranty is void without professional installation and registration.
Pros:- 10kW auxiliary heat strip included, unlike split systems that sell it separately
- All-in-one horizontal design eliminates lineset runs and indoor air handler installation
- Multi-speed ECM blower keeps airflow quiet despite the large 36K BTU capacity
- Durable galvanized steel cabinet with louvered coil protection for outdoor exposure
Cons:- 370 lb weight makes handling and rooftop installation labor-intensive
- 13.4 SEER2 efficiency trails comparable split systems by a full point or more
- Warranty requires qualified installation and online registration
Best for: Property owners in cooler climates who want a single-cabinet rooftop or ground-mounted unit with backup heat already installed
Not ideal for: Homes with existing ductwork configured for a split air handler — a packaged unit changes the whole installation approach
- Capacity:3 Ton (36,000 BTU)
- Refrigerant:R32
- Heat Strip:10kW auxiliary kit included
- Power Source:208/230V, 1-phase, 60Hz
- Dimensions:66″ D x 35″ W x 34″ H
- Weight:370 lbs
- Warranty:10-year parts limited with qualified installation and registration
Our verdict“The pick for cold-climate buyers who want backup heat built in and a single-box installation with no separate components.”
Goodman 3-Ton 15.2 SEER2 Multi-Position R-32 Heat Pump System with Air Handler
This is the efficiency leader among the full-size systems here, with a 15.2 SEER2 rating that edges out the 2.5-ton Goodman (14.3 SEER2) and clearly outpaces both Ace Air packaged units at 13.4. For a whole-home 3-ton system, that difference compounds into noticeably lower summer electricity bills. The system arrives pre-charged with R-32 for 15 ft of lineset, which simplifies installation compared with units requiring field charging, and the 9-speed ECM blower mirrors the airflow quality of the smaller Goodman bundles. What holds it back from being the default recommendation is the compressor design: a single-speed condenser fan and single-stage compressor mean it lacks the modulation of the Daikin Entra mini splits, and buyers considering downflow installation need an extra kit. The 75 dB outdoor noise level is also worth checking against where the condenser will sit.
Pros:- 15.2 SEER2 is the highest full-size efficiency rating in this roundup
- Pre-charged refrigerant for a 15 ft lineset reduces installation time and cost
- AHRI Certified and ETL Listed for verified performance
- Copper tube/enhanced aluminum fin coil supports durable heat transfer
Cons:- Single-speed condenser fan offers no outdoor airflow modulation
- Downflow installation requires a separately sold kit
- Requires professional installation and a new compatible outdoor placement
Best for: Homeowners replacing a 3-ton system who want the lowest operating costs available in this full-size lineup
Not ideal for: Buyers sensitive to outdoor noise — 75 dB near a patio or bedroom window may be intrusive
- Cooling Capacity:36,000 BTU (3 tons)
- Refrigerant:R-32
- Blower Motor:9-speed ECM, direct-drive
- Noise Level:75 dB
- Voltage:240 volts
- Configuration:Upflow, horizontal left/right (downflow kit sold separately)
- Certifications:AHRI Certified (No. 215217493), ETL Listed
Our verdict“The most efficient whole-home split in this batch, best for buyers who prioritize long-term operating savings over modulation and quiet.”
Goodman 2-Ton 15.2 SEER2 R-32 Heat Pump System with Front Return Air Handler and 10kW Heat Kit
This bundle fixes the most common gap in Goodman’s split-system lineup: the 10kW heat kit is factory-installed, so there’s no separate cold-weather purchase as with the Goodman 2.5 Ton 14.3 SEER2 system. Buyers get a condenser, air handler, and electric heat in one purchase, all at the same 15.2 SEER2 efficiency as the larger 3-ton Goodman — impressive at the 2-ton size. The wall-mounted front-return air handler is a different form factor than the multi-position AMST handlers, which makes it easier to place in tight spaces like closets but limits ducting flexibility. Like every Goodman here, the warranty hinges on professional installation and online registration within 60 days, a step many buyers miss. And with no inverter technology, it won’t match the Daikin Entra mini splits for quiet, modulated operation.
Pros:- Factory-installed 10kW heat kit eliminates a separate cold-climate purchase
- 15.2 SEER2 efficiency matches larger systems despite the compact 2-ton size
- Wall-mounted front-return air handler suits tight closet or utility placements
- AHRI certified system with 10-year parts warranty available
Cons:- Warranty void without qualified installation and registration within 60 days
- No inverter technology, so no capacity modulation
- Front-return handler limits ducting configurations compared with multi-position units
Best for: Small-home or light-commercial buyers who want a genuinely complete system — heating included — with no add-on purchases
Not ideal for: Homes needing multi-position ducting flexibility, since the front-return wall-mounted handler is less adaptable than multi-position units
- Capacity:2 tons
- Refrigerant:R-32
- Heat Kit:10kW, factory installed
- Air Handler:AWST30LU1310 wall-mounted, front return
- Compressor Type:Rotary scroll
- AHRI Certificate:215218025
- Warranty:10-year parts limited
Our verdict“The most complete Goodman package at this size — ideal for buyers who don’t want to shop for a heat kit separately.”
Ace Air 13.4 SEER2 Horizontal Heat Pump Package Unit, 2.5 Ton / 30,000 BTU with 10kW Electric Heat Kit
This is the smaller sibling of the Ace Air 3-ton GPHH3, and the comparison matters: same all-in-one horizontal design, same included 10kW heat strip, same R32 refrigerant, but at 30,000 BTU and a lighter 330 lbs it fits homes that don’t need 36K BTU of capacity. Against Goodman’s 2.5-ton split system (GLZS4BA3010 + AMST30BU1300), the Ace Air trades roughly a point of SEER2 efficiency for a dramatically simpler installation — one cabinet, one crane lift, no lineset, no indoor handler. The multi-speed ECM blower keeps it quieter than its size suggests, which matters for ground-level installs near living spaces. The 13.4 SEER2 rating means higher long-term energy costs than the 15.2 SEER2 Goodman systems, so this pick makes the most sense when installation simplicity outweighs operating efficiency.
Pros:- Complete single-cabinet design with 10kW heat kit included
- Lighter than the 3-ton version at 330 lbs, easing ground-level installation
- Multi-speed ECM blower delivers quieter operation than typical packaged units
- Environmentally friendly R32 refrigerant
Cons:- 330 lb weight still requires professional handling and equipment
- Warranty validity depends on professional installation and registration
- 13.4 SEER2 lags the most efficient split systems in this roundup
Best for: Owners of smaller homes or light-commercial spaces who want packaged simplicity with cold-weather heat included
Not ideal for: Efficiency-focused buyers — at 13.4 SEER2, long-term energy costs run higher than the 15.2 SEER2 split systems here
- Capacity:2.5 Ton / 30,000 BTU
- Refrigerant:R32
- Heat Strip:10 kW electric kit included
- Voltage:208/230V, 1-phase, 60Hz
- Dimensions:66″ D x 30″ W x 34″ H
- Weight:330 lbs
- Warranty:10-year parts limited
Our verdict“The right packaged unit for smaller homes that want one-box installation and built-in backup heat without 3-ton overkill.”
Daikin 18,000 BTU 18 SEER2 Entra R32 Series Heat Pump Mini Split Air Conditioner
This Daikin Entra stands out as the efficiency leader of the single-room options in this lineup, posting an 18 SEER2 rating that clearly outruns the Goodman split systems here, which sit in the 13.4–15.2 SEER2 range. The DC inverter compressor modulates its output between 5,800 and 22,500 BTU in heating mode, which means the unit ramps up and down instead of cycling on and off — translating to steadier temperatures and lower running costs for a bedroom, sunroom, or detached office up to 1,000 sq. ft. Compared with the larger Daikin 24,000 BTU Entra also in this roundup, this model is the better fit when one zone is all you need, since paying for extra capacity goes to waste in smaller spaces. The complete kit (line set, bracket, cables) softens the install burden that mini splits usually carry, though professional setup is still the realistic path. The tradeoff is fundamental: one indoor head means one room, period.
Pros:- 18 SEER2 with DC inverter modulation beats every Goodman system in this lineup on efficiency
- Wide operating range down to 5°F for heating and up to 115°F for cooling
- Photocatalytic air-purifying filter and adjustable airflow direction add comfort beyond raw heating and cooling
- Ships as a complete kit with line set, cables, and mounting bracket
Cons:- Single-zone design limits it to one room or open space
- Professional installation is realistically required, adding to total cost
Best for: Homeowners heating and cooling a single large room, addition, garage conversion, or small apartment who want the lowest operating costs per square foot
Not ideal for: Whole-house buyers — a single wall-mounted head can’t serve multiple rooms, so anyone needing multi-zone coverage should look at the Goodman split systems or packaged units in this guide
- Cooling Capacity:18,100 BTU (6,900–20,000 range)
- Heating Capacity:18,000 BTU (5,800–22,500 range)
- SEER2:18
- HSPF2:9
- Refrigerant:R-32
- Coverage Area:Up to 1,000 sq. ft.
- Heating Operating Range:5°F to 65°F
- Line Set Length:15 ft (1/4 x 1/2 in)
Our verdict“If you’re conditioning one space and want the best efficiency per square foot in this roundup, this Daikin is the clear pick.”
Goodman 2-Ton 14.3 SEER2 Multi-Position R-32 Heat Pump System with Air Handler (GLZS4BA2410 + AMST24BU1300)
This Goodman pairing earns its spot as the most sensible whole-home entry point in this guide. At 2 tons (24,000 BTU), it’s sized for smaller houses, condos, and well-insulated homes — a tier below the Goodman 2.5-Ton and 3-Ton R-32 systems featured elsewhere here, and better matched to buyers who would otherwise pay for unused capacity. The multi-position air handler is the quiet differentiator versus the packaged Ace Air units in this roundup: it installs vertically or horizontally, so it can slip into a closet, attic, or crawlspace instead of demanding a rooftop or ground pad. The tradeoffs are real, though. At 74 dB, the condenser is louder than a mini split like the Daikin Entra, and the invoice doesn’t stop at the unit — thermostat, sensors, and a heat kit for cold climates are all sold separately. The 10-year parts warranty also hinges on professional installation and registration within 60 days, so DIYers lose that protection.
Pros:- Multi-position air handler fits attics, closets, and crawlspaces where packaged units can’t go
- Corrosion-resistant aluminum coil with grooved tubing improves heat transfer and longevity
- Pre-charged for 15 ft of tubing with service valves and gauge ports for straightforward setup
- 10-year parts warranty with AHRI-certified matched performance
Cons:- Thermostat, sensors, and cold-climate heat kit all sold separately
- 74 dB condenser noise is noticeably louder than mini split alternatives
- Warranty void without qualified installation and registration within 60 days
Best for: Owners of smaller homes (roughly 800–1,200 sq. ft. of conditioned space) replacing an old split system who want flexible ducted installation and a long parts warranty
Not ideal for: Cold-climate buyers without a budget for the separately sold heat kit, or anyone wanting a quiet, plug-and-play single-room solution — this is a ducted whole-home system that requires professional install
- Cooling Capacity:24,000 BTU (2 Ton)
- SEER2:14.3
- Refrigerant:R-32
- Noise Level:74 dB
- Voltage:230V
- Installation Type:Split system, multi-position air handler
- Warranty:10-year parts (qualified install + registration within 60 days)
- AHRI Certificate:215213871
Our verdict“A solid, warranty-backed foundation for a small home’s ducted system — just budget for the add-ons and a pro installer before comparing prices.”
How We Picked
I evaluated each model against four buyer-relevant criteria. Efficiency came first: the spread here runs from 13.4 to 18 SEER2, and that gap translates directly into monthly operating costs over a 10–15 year lifespan. Configuration fit came second — a packaged unit, a multi-position split, and a ductless mini split serve completely different homes, so I ranked models against their direct peers rather than across categories. Completeness of the package was third: systems that bundle an air handler, heat kit, or thermostat (like the Goodman 2-Ton with the 10kW kit or the 14.3 SEER2 system with a thermostat) reduce hidden costs and installation surprises. Brand support and parts availability rounded out the criteria, where Goodman’s distribution network and Daikin’s mini split track record both carry weight.
The ranking logic follows a simple principle: higher-efficiency split systems rank above packaged units when installation complexity is manageable, because long-term savings outweigh the upfront difference for most homeowners. Packaged units earn their spots for retrofit simplicity, mobile homes, and horizontal-only duct situations. Mini splits are judged separately since they compete on installation ease and zoning rather than whole-home capacity.
Factors to Consider When Choosing Best R290 Heat Pumps
Choosing between these twelve models comes down to a handful of decisions that have nothing to do with spec sheets — and getting them wrong is where most buyers lose money.Packaged Unit or Split System: Match the Format to Your Ducts
The single biggest mistake buyers make is choosing a heat pump format that fights their existing infrastructure. If your home has a rooftop or crawlspace-mounted single cabinet, a packaged unit like the Ace Air or Goodman GPHH3 models is the only sensible retrofit — converting to a split system means new refrigerant lines, a new pad, and significantly more labor. Conversely, if you already have a conventional indoor air handler and duct network, a split system like the GLZS4BA3610 will deliver better efficiency from the same footprint. The horizontal configuration on the Ace Air units matters here too: it’s built for crawlspace and attic installs where a standard downflow unit simply won’t fit. Ask your installer which format your ducts actually support before comparing efficiency numbers at all.
SEER2 Ratings: What the Gap Actually Costs You
The difference between 13.4 and 15.2 SEER2 sounds small, but it compounds across every cooling season you own the system. As a rough frame, moving up roughly two SEER2 points typically trims 10–15% off cooling energy use, which matters most in hot climates with long summers. In mild climates, the payback period on the premium efficiency stretches out considerably — sometimes past the point where the cheaper unit is the smarter buy. The Daikin mini splits at 18 SEER2 sit at the top of this lineup, but their advantage is confined to the spaces they condition. My advice: if you run cooling more than four months a year, pay for the 15.2 SEER2 Goodman systems; if your summers are short, the 13.4 SEER2 packaged units are perfectly rational.
Tonnage: Oversizing Is the Silent Killer
Buyers routinely overbuy capacity because bigger feels safer, and it backfires. An oversized heat pump short-cycles: it satisfies the thermostat too quickly, never runs long enough to dehumidify, wears out compressors faster, and creates cold-clammy rooms despite correct temperatures. A 3.5 Ton unit like the Ace Air is right for roughly 1,800–2,400 square feet in average climates, but insulation quality, ceiling height, window exposure, and climate zone shift that range dramatically. A proper Manual J load calculation from your installer costs little and prevents a multi-thousand-dollar sizing error. If you’re between two sizes, the smaller unit is usually the correct call for comfort — sizing up is only justified in extreme cooling climates.
Backup Heat Kits: Don’t Discover This Gap in January
Three models in this roundup ship with a 10kW electric heat kit, and the rest don’t — a detail that’s easy to miss and expensive to fix later. Air-source heat pumps lose capacity as outdoor temperatures drop, and in colder regions the electric resistance backup is what keeps the house warm on the worst nights of the year. Buying the heat kit separately after the fact means another purchase, another installer visit, and potentially compatibility headaches. If you live anywhere with design temperatures below roughly 20°F, either choose a model with the kit included (the Ace Air packaged units are strong here) or budget for the kit at purchase time. In genuinely cold climates, also ask whether the heat kit wattage matches your home’s heat loss — 10kW covers most 2–3 ton applications but isn’t universal.
Refrigerant Transition: Why R-32 and R290 Models Exist Now
The entire market is mid-transition away from older high-GWP refrigerants, driven by regulation phasing down HFC production. That’s why every model here uses a next-generation refrigerant — R-32 in these units, with R290 (propane) emerging in some European and niche products. For buyers, this matters in two practical ways. First, future parts and refrigerant availability: buying an old-refrigerant system today means pricier recharges and repairs as supply shrinks. Second, installation rules differ — newer refrigerants have different handling requirements, so confirm your installer is certified for the refrigerant in the unit you choose. A system bought on clearance with obsolete refrigerant can be a false economy within five years.
Total Cost of Ownership Beats Sticker Price
The cheapest system on paper is rarely the cheapest over a 15-year horizon. Installation labor often costs as much as the equipment itself, and split systems carry higher install costs than packaged units even when the hardware price is similar. Factor in expected efficiency savings, the included accessories (air handler, heat kit, thermostat — three of these models bundle them), and warranty terms before comparing prices. Goodman’s strong parts distribution means faster, cheaper repairs in most of the country; Daikin’s mini splits have fewer field-serviceable parts but excellent compressor longevity. My rule of thumb: calculate purchase price plus ten years of estimated energy use, and only then decide whether the premium model earns its place.
Frequently Asked Questions
Are these R-32 models a good substitute if I was specifically shopping for R290 heat pumps?
Largely yes, depending on why you wanted R290. If your goal is low global warming potential, R-32 delivers roughly two-thirds lower GWP than older R-410A refrigerants, which is why the major US manufacturers have moved to it ahead of R290. If your goal is the absolute lowest GWP — R290 (propane) has a near-zero GWP — then true R290 products remain limited in North America, mostly tank water heaters and some imported units, because propane’s flammability restricts charge sizes in large residential systems. The models in this roundup represent the practical, code-approved low-GWP options actually available at scale in 2026. Waiting for mainstream R290 whole-home heat pumps likely means several more years of limited selection and installer support.
Should I choose a packaged unit or a split system if my ducts could support either?
If your duct layout genuinely supports both, the split system usually wins on efficiency — the 15.2 SEER2 Goodman splits clearly beat the 13.4 SEER2 packaged units on operating cost. Packaged units win on installation speed, serviceability (everything sits in one outdoor cabinet), and total installed cost, which is why they dominate mobile homes, rooftop retrofits, and crawlspace installations. One practical consideration: packaged units expose all components to weather, which can shorten cabinet life in coastal or harsh climates, while split systems keep the air handler indoors. Get quotes for both formats from your installer — the labor difference is often large enough to flip the total-cost math.
Is a 13.4 SEER2 rating bad in 2026?
No — 13.4 SEER2 is roughly the current minimum federal standard for the sizes in this lineup, meaning these units are legal, code-compliant, and efficient enough for many homes. The question is whether paying for more efficiency pays back in your climate. In a mild-climate home where cooling runs a few months a year, a 13.4 SEER2 packaged unit may never recoup the premium of a 15.2 SEER2 split system. In hot climates like the Southeast or Southwest, the efficiency gap compounds over six-plus months of annual cooling and the higher-rated units typically justify themselves within a decade. Treat 13.4 as the rational budget choice, not a compromise, if your cooling load is light.
Can a Daikin Entra mini split heat a whole room through winter, or is it just for cooling?
The Entra R32 models are true heat pumps, not air conditioners, so they heat as well as cool — the 24,000 BTU model handles roughly 800–1,200 square feet depending on insulation and climate. Their heating performance holds up well into moderately cold outdoor temperatures, though output tapers in extreme cold like all air-source units. For a well-insulated addition, garage conversion, or sunroom, one of these units can be the sole heating and cooling source without ductwork. What they can’t do is serve a whole house unless you install multiple indoor heads, at which point a ducted split system often becomes more economical. Match the BTU size to the room’s actual heat loss rather than its floor area for the best winter results.
Do I need the 10kW heat kit, or is it an upsell?
It depends entirely on your winter design temperature, and it’s not an upsell in most cold regions. Heat pump output drops as outdoor temperatures fall, and a 10kW electric resistance kit covers the gap on the coldest nights and during defrost cycles. If your area regularly drops below the low 20s°F, the kit is cheap insurance and I’d choose a model that includes it — like the Ace Air packaged units or the Goodman 2-Ton with the AWST air handler. In warm-winter climates (central Florida, southern Texas, coastal California), the heat pump alone rarely needs backup and the kit will sit unused. One caution: electric resistance heat is expensive to run, so treat the kit as an emergency and cold-snap tool, not everyday primary heat.
Conclusion
After comparing all twelve models, the right pick depends less on spec sheets and more on what your home and climate demand. For best overall, the Goodman 3-Ton 15.2 SEER2 Multi-Position R-32 System (GLZS4BA3610 + AMST42CU1300) delivers the strongest combination of efficiency, capacity, and install flexibility in this lineup. For best value, the Goodman 2-Ton 14.3 SEER2 Multi-Position System hits the efficiency-versus-cost sweet spot for smaller homes. For best premium, the Daikin 24,000 BTU 18 SEER2 Entra R32 mini split is the most efficient model here and ideal for additions, garages, or ductless zones. For beginners and retrofit buyers, the Ace Air 3 Ton packaged unit with the included 10kW heat kit offers the simplest, most complete one-cabinet solution with cold-weather backup built in. And for large or hot-climate homes, the Ace Air 3.5 Ton covers serious square footage without overcomplicating the install. Size to your actual load, match the format to your ducts, and the best R290-class heat pump for your situation becomes an easy call.
