The best air conditioners and heat pumps depend on your space, installation options, and whether you need cooling alone or year-round temperature control. My best overall pick is the Daikin Entra R32 18,000 BTU mini-split, a strong fit for buyers seeking a dedicated single-zone system from an established HVAC brand. The Temprium 12,000 BTU mini-split stands out for its listed 22 SEER2 efficiency, while the Midea Duo portable unit suits renters or rooms where permanent installation is not practical. The main tradeoffs are installation effort, heating performance, efficiency, and the flexibility to move or expand a system. Read on for the full comparison, selection criteria, and advice on matching a system to your home.

Key Takeaways
- The lineup splits into three distinct installation paths: ductless mini-splits for single rooms or zones, portable units for flexibility, and central systems for homes with compatible ductwork.
- Higher listed SEER2 figures are not the whole efficiency story: the Temprium‘s 22 SEER2 is a standout specification, but sizing, climate, installation quality, and operating conditions also shape energy use.
- Portable heat-pump models trade installation simplicity for room-by-room coverage: they avoid a permanent outdoor unit but are not direct substitutes for whole-home central systems.
- Capacity spans small rooms to whole-home applications: the Garvee‘s 9,000 BTU mini-split and the 24,000 BTU Senville LETO serve different loads, so choosing by price or brand alone risks poor sizing.
- Central-system picks serve a different buyer from ductless and portable units: the Senville 3-ton inverter and Goodman systems make the most sense when existing ductwork, professional installation, and broader home coverage are priorities.

More Details on Our Top Picks
Albott 12,000 BTU Mini Split Air Conditioner and Heater, 115V, SEER2 18
The Albott suits buyers who want one ductless system for heating, cooling, dehumidifying, and air circulation across a space up to 750 sq. ft. Its stated operating range of 5°F to 122°F gives it a broad climate envelope, while app and remote controls, a timer, and sleep mode make day-to-day adjustments straightforward. Compared with the Temprium 12,000 BTU, it has a lower listed efficiency rating and lacks voice control, but it specifies a longer heating-and-cooling temperature range. The tradeoff is installation: this requires a new outdoor unit and professional HVAC work, so it is not a quick replacement for a window unit. I would also verify the warranty before buying; the listing gives conflicting coverage details, despite describing five-year compressor and seven-year parts terms.
Pros:- Combines cooling, heating, dehumidifying, and fan modes
- Rated for spaces up to 750 sq. ft.
- App and remote controls include timer and sleep settings
- Self-cleaning feature and removable filters support routine upkeep
Cons:- Requires a new outdoor unit and professional HVAC installation
- Warranty information conflicts within the listing
- SEER2 18 is lower than the listed ratings of the Temprium and COSTWAY options
Best for: Homeowners who need a 115V ductless system for a room up to 750 sq. ft. and want a stated operating range down to 5°F.
Not ideal for: Renters or buyers seeking a simple self-installed unit, and anyone who needs clear, consistent warranty terms before purchase.
- Cooling capacity:12,000 BTU
- Efficiency:SEER2 18
- Voltage:115 volts
- Coverage area:Up to 750 sq. ft.
- Noise level:29 dB
- Refrigerant:R32
- Operating temperature range:5°F to 122°F
- Controls:App and remote
Our verdict“Choose the Albott if its stated broad operating range matters more to you than higher listed efficiency or voice control.”
Temprium 12,000 BTU 115V Mini-Split Air Conditioner and Heat Pump, 22 SEER2
The Temprium stands out among these compact mini-splits for combining a listed 22 SEER2 rating with app, remote, and voice controls. Its 23 dB minimum noise figure also makes it a strong candidate for bedrooms or workspaces where indoor sound matters. It provides 12,000 BTU of cooling and 12,300 BTU of heating for areas up to 750 sq. ft.; compared with the Albott 12,000 BTU, it adds voice control and a higher listed efficiency rating, though the Albott specifies operation down to 5°F. The Temprium’s main compromise is its one-year warranty, shorter than the coverage stated for the COSTWAY. It also needs a new outdoor unit and installed split-system connections, so smart features do not make it a plug-in option.
Pros:- Lists 22 SEER2 efficiency
- Supports app, remote, and voice controls
- Minimum stated noise level is 23 dB
- Includes washable filter and self-cleaning function
Cons:- One-year warranty is shorter than the stated COSTWAY warranty
- Requires a new outdoor unit and split-system installation
- Coverage is limited to spaces up to 750 sq. ft.
Best for: Owners of a bedroom, office, or other space up to 750 sq. ft. who want app or voice control and quiet operation.
Not ideal for: Buyers who prioritize a longer stated warranty, need a plug-in appliance, or require a specified low-temperature heating range.
- Cooling capacity:12,000 BTU
- Heating capacity:12,300 BTU
- Efficiency:22 SEER2
- Voltage:115 V
- Coverage:Up to 750 sq. ft.
- Noise level:As low as 23 dB
- Refrigerant:R-32
- Warranty:1 year
Our verdict“Pick the Temprium for a quiet, connected 115V mini-split, provided its short warranty and installation needs suit your plans.”
COSTWAY 12,000 BTU Mini-Split Air Conditioner and Heater
The COSTWAY’s clearest distinction in this group is its stated five-year parts and eight-year compressor warranty, paired with a 20 SEER2 rating and both heating and cooling. For a room up to 750 sq. ft., inverter operation and an ECO setting are intended to manage output rather than run at a constant full blast; a washable filter, self-cleaning, and auto-defrost add useful upkeep features. Compared with the Temprium 12,000 BTU, the COSTWAY lists a longer warranty but gives you a remote rather than app and voice controls. Its 23 dB listed noise level matches the Temprium’s minimum figure. The drawback is that installation must be handled by a licensed HVAC installer, and a compatible outdoor unit is required. I’d favor it for warranty terms and basic controls, not for smart-home convenience.
Pros:- States a five-year parts and eight-year compressor warranty
- Lists 20 SEER2 efficiency with inverter and ECO operation
- Includes washable filter, self-cleaning, and auto-defrost features
- Remote offers timer and sleep-related settings
Cons:- Requires a licensed HVAC installer
- Needs a new compatible outdoor unit
- Remote-only control lacks the app and voice options offered by the Temprium
Best for: Homeowners who want a 12,000 BTU ductless heat pump with stated multi-year parts and compressor coverage and do not need app controls.
Not ideal for: Renters, DIY buyers, or people who specifically want Wi-Fi or voice operation.
- Cooling capacity:12,000 BTU
- Coverage:Up to 750 sq. ft.
- Efficiency:20 SEER2
- Voltage:115 V
- Noise level:23 dB
- Refrigerant:R-32
- Installation:Split system; licensed HVAC installer required
- Warranty:5 years parts; 8 years compressor
Our verdict“Choose the COSTWAY if its stated warranty and maintenance features matter more than app-based control.”
Senville LETO 24,000 BTU Mini Split Air Conditioner and Heat Pump
With 24,000 BTU of cooling and heating capacity, the Senville LETO is the clear choice here for buyers whose needs exceed the 12,000 BTU systems’ stated coverage of up to 750 sq. ft. It is a ductless heat pump with cooling, heating, dehumidifying, and air-circulation modes, plus app, Alexa, and remote control. The package includes both indoor and outdoor units and a 16-foot line set, unlike the COSTWAY 12,000 BTU, which requires a separately sourced compatible outdoor unit. That more complete package still does not make installation a DIY job: professional installation is required. Its stated heating function reaches down to 5°F, but the one-year parts warranty excludes labor, leaving installation and service costs outside that coverage. The listed 208/230V requirement also makes it a different electrical fit from the 115V models.
Pros:- 24,000 BTU cooling and heating capacity
- Includes indoor and outdoor units and a 16-foot line set
- App, Alexa, and remote control support
- Heat pump operation is stated down to 5°F
Cons:- Requires professional installation
- 208/230V electrical supply differs from the 115V systems in this group
- Parts warranty is one year, and labor is not covered
Best for: Homeowners with a larger area needing more capacity than a 12,000 BTU single-zone mini-split can provide.
Not ideal for: People cooling a small room, buyers limited to 115V power, or anyone seeking labor coverage under the warranty.
- Cooling and heating capacity:24,000 BTU
- System type:Ductless mini split
- Voltage:208/230 V
- Wattage:2,500 watts
- Noise level:34 dB
- Refrigerant:R-454B
- Heating operation:Heat pump functional down to 5°F (-15°C)
- Warranty:1 year on parts; 5 years on compressor; labor not included
Our verdict“Choose the Senville LETO when you need 24,000 BTU capacity and have the electrical supply and professional installation arranged.”
MEPTY 12,000 BTU 115V Ductless Mini-Split Air Conditioner and Heat Pump
The MEPTY covers the basics for a 12,000 BTU ductless system: cooling, heating, fan, and dehumidifying modes, inverter operation, a remote, and a 24-hour timer. Its stated coverage is up to 750 sq. ft., and mute mode is rated at 26 dB, making it a quieter listed option than the Albott at 29 dB, though not as quiet as the Temprium or COSTWAY at 23 dB. Its 19 SEER2 rating sits between those models’ listed efficiency figures and Albott’s SEER2 18. The tradeoff is a simpler control setup: there is no listed app or voice support, and regular filter cleaning is recommended. Like the other 12,000 BTU ductless choices, it needs a compatible outdoor unit, so the remote and timer do not remove the need for professional system installation.
Pros:- Provides four operating modes, including heating and dehumidifying
- Lists 19 SEER2 efficiency and inverter operation
- Mute mode is rated at 26 dB
- Remote includes a 24-hour timer
Cons:- Requires a new compatible outdoor unit
- No app or voice control is listed
- Regular air-filter cleaning is recommended
Best for: Homeowners who want a straightforward 115V mini-split with a timer and quiet mute mode for a space up to 750 sq. ft.
Not ideal for: Buyers who want app or voice control, or those who prefer a package that does not require sourcing a compatible outdoor unit.
- Cooling capacity:12,000 BTU
- Efficiency:19 SEER2
- Voltage:115 V
- Wattage:1,100 W
- Coverage:Up to 750 sq. ft.
- Noise level:26 dB in mute mode
- Refrigerant:R32
- Controls:Remote control
Our verdict“Choose the MEPTY for straightforward remote operation and a quieter listed mute mode, not for connected controls.”
Daikin Entra R32 18,000 BTU Single-Zone Heat Pump Mini-Split System
The Daikin Entra is a sensible pick for buyers who want a ductless system sized for a larger single room or zone, with published heating and cooling capacities around 18,000 BTU. Its inverter operation and 18 SEER2 rating offer a more efficient route than a portable unit such as the Westinghouse 14,000 BTU, while the included line set, wiring, remote, and bracket give the installation package a useful head start. The photocatalytic filter and adjustable airflow add everyday flexibility, but they do not change the main tradeoff: this is a permanently installed system, not a plug-in appliance. It also needs 230-volt wiring and a new outdoor unit. Compared with the Senville AURA, the Daikin lists a 10-year warranty and R-32 refrigerant, but lacks the AURA’s stated app and Alexa control.
Pros:- Provides both heating and cooling with variable capacity.
- 18 SEER2 efficiency rating and R-32 refrigerant.
- Includes a 15-foot line set, wiring, remote, and wall-mounting bracket.
- Lists a 10-year manufacturer warranty and a photocatalytic air-purifying filter.
Cons:- Requires a dedicated 230-volt electrical supply.
- Needs an outdoor unit and professional-grade installation rather than a window setup.
- Does not list app or voice control.
Best for: Homeowners needing a permanently installed, single-zone heat pump for a room or open area approaching 1,000 square feet, with 230-volt power available.
Not ideal for: Renters or buyers seeking a simple portable setup, or homes without suitable 230-volt wiring and space for an outdoor unit.
- Cooling capacity:18,100 BTU (6,900–20,000 BTU)
- Heating capacity:18,000 BTU (5,800–22,500 BTU)
- Coverage area:Up to 1,000 sq. ft.
- Efficiency:18 SEER2; 9 HSPF2; 10.5 EER2
- Refrigerant:R-32
- Electrical:230 volts
- Noise level:37 dB
- Operating ranges:Cooling: 50°F–115°F; heating: 5°F–65°F
- Included line set and warranty:15 ft, 1/4 x 1/2 in; 10-year manufacturer warranty
Our verdict“Choose the Daikin Entra if you want a well-equipped, fixed mini-split for one zone and can accommodate its electrical and installation requirements.”
Senville AURA 18,000 BTU Mini Split Air Conditioner and Heat Pump
The AURA earns its place for buyers who need a mini-split that is specified to keep heating in very cold weather: its stated operating limit reaches -22°F, a more explicit cold-weather claim than the Daikin Entra’s listed 5°F heating floor. It also brings Alexa and app control, plus a 27 dB noise figure, giving it a quieter, more connected profile than the larger Senville 3-Ton system. The 16-foot copper line set and wiring harness are included, but this is still a professional-installation purchase and needs 208–230V power. The main caution is warranty coverage: parts are listed for two years and the compressor for seven, shorter than the Daikin’s stated 10-year manufacturer warranty. Buyers should also check that the listed 1,000-square-foot coverage suits their actual room and climate.
Pros:- Heating operation is specified down to -22°F.
- App and Alexa control complement the included remote.
- Listed at 21.5 SEER and Energy Star certified.
- Includes a 16-foot copper line set and wiring harness.
Cons:- Professional installation is required.
- Requires 208–230V electrical service.
- Warranty is listed as two years for parts and seven years for the compressor.
Best for: Homeowners in cold regions who need ductless heating for a zone up to about 1,000 square feet and want app or Alexa controls.
Not ideal for: Buyers prioritizing a longer stated warranty, DIY installation, or a system that can run on standard 115V power.
- Cooling power:17,000 BTU
- Capacity:1.5 tons
- Coverage area:1,000 sq. ft.
- Efficiency:21.5 SEER
- Electrical:208–230V; 1,360 watts
- Noise level:27 dB
- Refrigerant:R-454B
- Controls:Alexa, app, and remote
- Warranty:2 years parts; 7 years compressor
Our verdict“Pick the Senville AURA when cold-weather heating and connected controls matter more than DIY setup or a longer listed warranty.”
BLACK+DECKER Smart Portable Air Conditioner with Heat, 14,000 BTU
For someone who cannot install a split system, this BLACK+DECKER offers cooling, heating, dehumidifying, and fan modes in a movable, window-vented package. Wi-Fi, voice control, and a remote with Follow Me thermostat functionality add convenience that the fixed Daikin Entra does not provide, and the 115V requirement is easier to accommodate in many rooms. The tradeoff is that portable units need an exhaust hose and occupy floor space; at 54 dB, it is also a louder choice than the Westinghouse portable listed at 51 dB. I would be cautious about sizing: the listing gives coverage of up to 700 square feet in one place and 375 square feet in another, while heating capacity and refrigerant details also conflict. That makes it a less dependable choice for buyers who need a precise capacity match.
Pros:- Combines air conditioning, heating, dehumidifying, and fan modes.
- Supports Wi-Fi, app, Alexa, and Google Assistant controls.
- Follow Me remote can use its location as a thermostat reference.
- Includes a window installation kit and washable filter.
Cons:- Published room coverage conflicts between 375 and 700 square feet.
- Heating capacity and refrigerant information are inconsistent in the listing.
- Requires window venting, takes up floor space, and is listed at 54 dB.
Best for: Renters or homeowners who need a movable, 115V unit with both heating and cooling plus app or voice controls.
Not ideal for: Buyers who need verified room sizing, quiet operation, or a permanent whole-zone heat-pump installation.
- Cooling capacity:14,000 BTU ASHRAE; 10,200 BTU SACC
- Heating capacity:10,000 BTU in item details; 12,000 BTU in product information title
- Listed room coverage:375 sq. ft. in capacity details; up to 700 sq. ft. in description
- Functions:Air conditioner, heater, dehumidifier, fan
- Electrical:115V; 1,365 watts
- Noise level:54 dB
- Dimensions and weight:16.5 × 14.06 × 27.09 in; 35 lbs
- Controls:Wi-Fi, mobile app, Alexa, Google Assistant, remote
- Warranty:1 year
Our verdict“Choose this BLACK+DECKER for flexible portable comfort and smart controls, but not when exact capacity or quiet operation is a priority.”
Westinghouse 14,000 BTU Portable Air Conditioner with Heat Pump
The Westinghouse is the more straightforward choice for buyers who want portable heating and cooling without committing to a wall-mounted system. Its listed 51 dB noise level is lower than the BLACK+DECKER’s 54 dB, and the washable filter, Wi-Fi app, remote, and window kit cover the essentials. The stated 90-pint-per-day dehumidifier capacity also gives it a useful role in damp rooms, beyond temperature control. Against the Daikin Entra, the advantage is mobility and standard 115V power; the disadvantage is that a portable unit vents through a window and is not a permanent heat-pump installation. Capacity information deserves a check before purchase: the title says 14,000 BTU while product details also list 14,000 BTU cooling, but the listing notes a discrepancy. Its 700-square-foot claim should not substitute for a room-specific capacity assessment.
Pros:- Offers cooling, heating, fan, and dehumidifier modes.
- Lists coverage up to 700 square feet and 90 pints per day of dehumidification.
- Wi-Fi app control and remote are included.
- Washable filter and window vent kit support routine upkeep and setup.
Cons:- Requires an exhaust hose and a suitable window opening.
- Cooling-capacity information is flagged as inconsistent in the listing.
- At 51 dB, it is not as quiet as a low-noise ductless option such as the Senville AURA.
Best for: People in apartments or rooms without permanent HVAC who want portable heating, cooling, and dehumidification with app control.
Not ideal for: Buyers seeking a quiet bedroom unit, a fixed high-efficiency system, or a capacity specification free of listing ambiguity.
- Cooling power:14,000 BTU listed
- Room coverage:Up to 700 sq. ft.
- Modes:Cooling, heating, fan, dehumidifier
- Dehumidifier capacity:90 pints per day
- Electrical:115V; 1,250 watts
- Noise level:51 dB
- Refrigerant and filter:R-32; washable filter
- Dimensions:15.6 × 18.1 × 34.1 in.
- Controls and setup:Wi-Fi app, remote, control panel; window vent kit included
Our verdict“The Westinghouse suits buyers who need a movable all-season unit and accept window venting in exchange for avoiding fixed installation.”
Senville 3-Ton Inverter Heat Pump Central Air Conditioning System
Where the mini-splits in this roundup serve individual zones, this 36,000 BTU split system is aimed at larger spaces, with stated coverage up to 2,000 square feet. The inverter compressor supports both heating and cooling, and its listed heating limit of -22°F gives it a stronger cold-weather claim than the Daikin Entra, whose stated heating range begins at 5°F. The scale comes with real installation demands: this is a 139-pound, 208/230V system that calls for licensed professional work, so it is not a portable alternative to the Westinghouse or a simple replacement for a window unit. It includes indoor and outdoor components plus a 16-foot installation kit, but labor is excluded from the warranty. Buyers should also confirm that their ductwork and home load match the system before choosing its larger capacity.
Pros:- 36,000 BTU capacity with listed coverage up to 2,000 square feet.
- Inverter compressor provides both heating and cooling.
- Heating operation is specified down to -22°F.
- Includes indoor air handler, outdoor condenser, wired remote, and 16-foot installation kit.
Cons:- Professional installation is recommended and 208/230V power is required.
- At 139 lbs, the outdoor equipment is substantial and not suited to a portable setup.
- Warranty does not cover labor.
Best for: Homeowners with suitable ductwork who need a central-style heat pump for a larger area and want heating specified for very low outdoor temperatures.
Not ideal for: Renters, buyers without compatible ductwork, or anyone seeking a low-effort installation or labor-inclusive warranty.
- Cooling capacity:36,000 BTU
- Coverage:Up to 2,000 sq. ft.
- System type:Split system
- Compressor and refrigerant:Inverter; R-454B
- Heating operation:Down to -22°F (-30°C)
- Electrical:208/230V; 2,500 watts
- Noise level:44 dB
- Dimensions and weight:48 × 36 × 40 in; 139 lbs
- Warranty:5 years parts; 10 years compressor; labor not covered
Our verdict“Choose the Senville 3-Ton system for a larger ducted home needing cold-weather heat-pump capacity, provided professional installation and separate labor costs fit your plans.”
Goodman 3-Ton 15 SEER2 R-32 Heat Pump System with Air Handler
I’d shortlist this 3-ton split system for a home that needs central heating and cooling across multiple rooms, rather than a single-room solution like the Tehanld 12,000 BTU mini split. It arrives with both the outdoor heat pump and a multi-position air handler, and its 36,000 BTU capacity gives contractors a larger system to match to the home’s heating and cooling load. R-32 refrigerant and inverter technology are part of the package, while the listed efficiency is 15 SEER2.
The main tradeoff is that this is not a ready-to-install bundle: the lineset, thermostat, and other accessories are separate, and the heat kit must be from the HKSC/HKSX series, not HKR. At 361 pounds, it also calls for professional planning and installation. I’d choose it for a properly sized central-system project, not a casual equipment swap.
Pros:- Provides both heating and cooling through a central split system
- Includes a 3-ton outdoor unit and multi-position air handler
- 36,000 BTU capacity suits larger whole-home applications when correctly sized
- Uses R-32 refrigerant and lists inverter technology
Cons:- Lineset, thermostat, and other installation accessories are sold separately

Tehanld 12,000 BTU Mini Split Air Conditioner and Heat Pump, 115V, 17 SEER2, Up to 750 Sq. Ft., White
The Tehanld 12,000 BTU mini split suits buyers who want both heating and cooling in one zone without moving a portable unit between rooms. Its five operating modes include dry and fan settings, while four fan speeds plus sleep, quiet, turbo, and ECO options give occupants more ways to tune everyday comfort than the simpler mode set described for the Garvee 9,000 BTU mini split. It is listed for spaces up to 750 square feet, though actual coverage depends on the room and climate.
The included remote and 9.8-foot copper lineset reduce the number of parts a buyer must source compared with the Goodman central systems, but this is still not a DIY installation: a licensed HVAC professional is required. Its low-temperature operation is listed down to -4°F, yet buyers in colder areas should check whether that performance fits their heating needs. Two-package shipping may also mean the equipment arrives in separate deliveries.
Pros:- Heating and cooling in one 12,000 BTU ductless system
- Five operating modes and four fan speeds allow more control over room comfort
- Includes a remote and 9.8-foot copper line set
- Listed operation down to -4°F supports use in colder conditions
Cons:- Requires installation by a licensed HVAC professional
- Ships in two packages that may arrive at different times
- Listed coverage of up to 750 square feet may not suit every layout or climate
Best for: Owners of a single large room or open-plan space who want a permanently installed, 115V heating-and-cooling system with several comfort modes.
Not ideal for: DIY installers or buyers who need central conditioning for multiple closed rooms; professional installation is required, and one mini split may not distribute air evenly through a whole home.
- Cooling capacity:12,000 BTU
- Efficiency:17 SEER2
- Voltage:115V
- Listed coverage:Up to 750 sq. ft.
- Refrigerant:R32
- Operating modes:Cool, Heat, Auto, Fan, Dry
- Fan speeds:Low, Medium, High, Auto
- Low-temperature operation:Down to -4°F
- Included accessories:Remote control and installation kit with 9.8 ft. copper line set
Our verdict“Pick the Tehanld for a single-zone installation with useful operating modes and included line-set components, provided you have professional installation arranged.”
Goodman 2-Ton R-32 Heat Pump System with Multi-Position Air Handler
Compared with the 3-ton Goodman system in this roundup, this 2-ton version is the more fitting starting point for a smaller home or a lower-load central replacement—provided a contractor confirms the sizing. The package pairs a 24,000 BTU condenser with a multi-position air handler, so it can provide whole-home heating and cooling through existing ductwork rather than conditioning just one room like the Tehanld mini split. Its R-32 refrigerant and rotary scroll compressor are listed alongside a 10-year parts warranty, subject to qualifying installation and registration.
There is an unresolved specification discrepancy: the title gives 14.3 SEER2, while the details list 15.2 SEER. Those figures are different rating measures, so I would ask the seller or installer to confirm the certified efficiency for the exact system. A heat kit may be needed in cold climates, and the thermostat, kit, and other accessories are separate. That makes this a less turnkey choice than the Tehanld, despite its central-system format.
Pros:- Provides central heating and cooling with a condenser and multi-position air handler
- 24,000 BTU capacity is a smaller alternative to the 3-ton Goodman system
- Uses R-32 refrigerant and a rotary scroll compressor
- 10-year parts warranty is available with qualifying installation and registration
Cons:- Product information lists conflicting efficiency figures: 14.3 SEER2 in the title and 15.2 SEER in the details
- A heat kit may be needed in cold climates
- Thermostat, heat kit, and other accessories are sold separately
Best for: Homeowners replacing a central system in a smaller home or a home with a lower cooling load, working with a contractor who can verify capacity and the exact efficiency rating.
Not ideal for: Buyers who need a simple one-room installation, want all accessories included, or require a clearly confirmed efficiency figure before purchase.
- Cooling capacity:24,000 BTU
- Efficiency information:14.3 SEER2 in title; 15.2 SEER in details
- System type:Split system
- Refrigerant:R-32
- Voltage:230 V
- Compressor type:Rotary scroll
- Noise level:74 dB
- Condenser model:GLZS4BA2410
- Air handler model:AMST24BU1300
Our verdict“Consider this Goodman for a smaller ducted home only after an HVAC contractor confirms the system sizing, required accessories, and certified efficiency.”
Garvee 9,000 BTU Ductless Mini Split Air Conditioner and Heat Pump
The Garvee 9,000 BTU mini split is the compact-zone option here for buyers who value app control and a low reported mute-mode noise level. Its WiFi app and remote make temperature adjustments convenient, while inverter technology varies compressor speed instead of relying only on repeated full-power starts. That gives it a different appeal from the Tehanld 12,000 BTU model, which has greater stated capacity and more listed operating modes but lacks listed WiFi control. Garvee provides cooling, heating, drying, and fan modes.
The listed coverage reaches up to 750 square feet, but capacity is only 9,000 BTU, so I would not treat that figure as a universal room-size promise; insulation, layout, and climate affect fit. The product includes a copper line set and other installation components, yet professional HVAC installation is recommended. Buyers should also plan for two-package shipping and confirm installation requirements before relying on the included parts.
Pros:- Provides cooling, heating, drying, and fan modes
- WiFi app and remote offer two control options
- Inverter technology adjusts compressor speed
- Includes a copper line set, communication cable, power cord, and drain tube
Cons:- 9,000 BTU capacity may be insufficient for larger spaces despite the listed coverage claim
- Professional HVAC installation is recommended
- Ships in two separate packages
Best for: Owners of a small, well-defined zone who want a ductless heat pump with WiFi and remote controls and value quiet operation.
Not ideal for: Buyers with larger or poorly insulated rooms who need more capacity, or anyone expecting a straightforward DIY installation despite the included components.
- Cooling capacity:9,000 BTU
- Efficiency:18.5 SEER
- Listed coverage:Up to 750 sq. ft.
- Modes:Cooling, heating, drying, and fan
- Temperature range:60°F to 89°F
- Noise level:42 dB in mute mode
- Operating temperature:-13°F to 122°F
- Voltage and wattage:230 V; 2,640 W
- Controls:WiFi app and remote
Our verdict“Choose the Garvee for a smaller ductless zone where app control and quiet operation matter more than the Tehanld’s higher stated capacity and broader mode selection.”
Midea Duo 14,000 BTU Inverter Portable Air Conditioner with Heat
When a permanent mini split or ducted Goodman system is impractical, the Midea Duo portable offers both cooling and heat without a wall-mounted indoor unit. Its dual-hose design and inverter technology are intended to support more efficient operation than a basic single-hose portable layout, and the listed cooling noise can be as low as 42 dB. App, remote, button, and voice controls also make it the most flexible to manage from the shortlist. It is rated for rooms up to 550 square feet.
That flexibility comes with portable-unit compromises: the 77.2-pound cabinet is bulky to move, and the coverage is less than the up-to-750-square-foot claims for the Tehanld and Garvee mini splits. Its cooling rating is listed as 14,000 BTU, with a lower 12,000 BTU SACC figure also provided, so buyers should pay attention to the stated measurement when matching it to a room. The one-year parts-and-labor warranty is shorter than the Goodman systems’ listed parts coverage.
Pros:- Provides both cooling and heating without permanent ductless installation
- Dual-hose design and inverter technology support efficient operation
- App, remote, button, and voice controls are available
- Listed cooling noise is as low as 42 dB
Cons:- At 77.2 pounds, it is cumbersome to move between rooms
- Coverage is listed up to 550 square feet, less than the mini splits’ stated maximums
- One-year parts-and-labor warranty is shorter than the Goodman systems’ listed parts warranties
Best for: Renters or homeowners who need heating and cooling in one room but cannot install a ductless or central system, and want app or voice controls.
Not ideal for: Buyers seeking a permanent, whole-home system, frequent room-to-room portability, or a longer listed warranty; it is heavy and rated for less space than the mini splits.
- Cooling power:14,000 BTU; 12,000 BTU SACC
- Coverage:Up to 550 sq. ft.
- Functions:Cooling and heating
- Noise level:As low as 42 dB
- Voltage:115 V
- Wattage:1,300 W
- Dimensions:16.73 x 19.53 x 34.48 in
- Weight:77.2 lbs
- Warranty:One year parts and labor
Our verdict“Pick the Midea Duo when portability and avoiding permanent installation matter more than the broader coverage and fixed-system format of a mini split or central heat pump.”
How We Picked
I compared the 15 options by system type, stated capacity, heating and cooling capability, and efficiency information, then considered the practical demands each places on an owner. Mini-splits, portable units, and central systems do not solve the same problem, so I judged them against their intended use rather than treating them as interchangeable. I also weighed usability, installation needs, flexibility, and the value of stated features such as inverter operation, smart controls, and refrigerant type where those details were provided.
The ranking favors systems with a clear fit for a common buyer need, useful published specifications, and the potential to deliver more than one-season service. Dedicated ductless systems rank ahead for fixed-room comfort, while portable models are better for buyers who cannot install permanent equipment. Central systems place well for whole-home replacements but sit lower for buyers seeking a simple room solution because they require ductwork and professional installation. Where key performance details were not supplied, I avoid assuming advantages that cannot be confirmed.
Factors to Consider When Choosing Best Air Conditioners And Heat Pumps
Before choosing a model, I would start with the home and installation rather than a feature list. The right system depends on how much space it must serve, what equipment is already in place, and how often you need heat as well as cooling. These points can prevent costly mismatches that no efficiency label or extra feature can fix.
Match system type to the building
A portable unit, ductless mini-split, and central heat pump each solve a different installation problem. Portable models can suit renters or temporary room cooling, but they occupy floor space and need a window connection for their exhaust setup. A mini-split needs an outdoor unit and a path through the wall, making it a better fit for owners who want permanent control in a particular zone. Central systems can use existing ducts to condition multiple rooms, but a ducted home is not automatically compatible with every replacement system. Check access, electrical service, outdoor-unit placement, and any rental or building restrictions before choosing a type. The least complicated system to buy may not be the least disruptive one to live with.
Size for the room and heat load, not a rough square-foot claim
BTU capacity is a starting point, not a complete sizing method. Sun exposure, ceiling height, insulation, air leakage, occupancy, and kitchen equipment can all change the load on a room. An oversized unit may cycle in short bursts and leave conditions uneven, while an undersized one can struggle during the hottest or coldest periods. Published coverage estimates should be treated as rough guidance unless they account for the building and local climate. For a permanent mini-split or central installation, ask for a load calculation rather than selecting capacity by a simple square-foot rule. This matters especially when comparing the 9,000 BTU and 24,000 BTU options in this lineup.
Check heating performance for your winter climate
A heat pump’s ability to provide heat does not tell you how well it will do in your local winter. Capacity and efficiency can change as outdoor temperatures fall, and some homes need supplemental heat during cold spells. Look for published low-temperature heating data and the manufacturer’s operating range, not just a heating label or general claim. If you are replacing a furnace, compare the heat pump’s cold-weather performance with your home’s design conditions and discuss backup heat with an installer. In a mild climate, a single heat pump may cover most heating needs; in a colder region, system design and backup planning can matter as much as the unit itself. A cooling-focused buyer may reasonably give this factor less weight.
Read efficiency figures alongside the full specification
SEER2 provides a useful seasonal cooling comparison, but it does not capture every part of ownership. Heating efficiency, performance at different outdoor temperatures, installation quality, controls, and how the system is operated also affect energy use. A high figure can be attractive, as with the Temprium’s stated 22 SEER2, but compare models only when their ratings and test basis are presented consistently. For central systems, check that the outdoor unit and air handler form a compatible rated combination rather than assuming either component’s label tells the whole story. Ask an installer to explain the expected performance for your region and usage pattern. Efficiency is most useful when it helps compare correctly sized, properly installed systems.
Budget for installation, electrical work, and upkeep
The equipment is only part of a permanent system’s total project. Mini-splits may call for electrical work, a mounting location, a condensate route, and line-set installation, while central replacements can involve duct repairs, air-handler changes, or other system updates. Portable units avoid much of that fixed installation work, but their window setup, condensate handling, and need for clear airflow still affect daily use. Confirm who is responsible for installation and commissioning, what the warranty requires, and whether qualified service is available nearby. Keep filters and accessible coils clean according to the manufacturer, and arrange professional maintenance when the system calls for it. A lower-complexity installation can be a better fit than a feature-rich unit if the latter adds work your home cannot support.
Decide how much flexibility and control you need
Think about how your household uses rooms across the day before paying for controls or multiple zones. A single-zone mini-split can make sense when one area needs independent conditioning, but it will not automatically solve temperature differences throughout a whole house. Portable models can be moved, though their exhaust connection and room coverage can limit how convenient that flexibility feels. Smart features are most useful when they match a real routine, such as remote scheduling or adjusting a room that is not used all day. If several rooms need separate settings, ask whether a multi-zone design is more suitable than placing one oversized unit in a central spot. For a straightforward space, a simpler control setup may be easier to maintain and use.
Frequently Asked Questions
Can a portable air conditioner with heat replace a mini-split?
Usually not as a direct, like-for-like replacement. A portable unit is easier to set up and can suit a room where permanent installation is off limits, while a mini-split is a fixed system designed to serve a zone without taking up floor space. Portable models also depend on a suitable window connection and can be less convenient when you want continuous, whole-room comfort. A mini-split requires more planning, an outdoor unit, and installation, but it is generally the more suitable path for a permanent room-conditioning project. Choose based on your building rules, room needs, and willingness to install fixed equipment.
Is a 12,000 BTU mini-split suitable for my room?
It may be, but the BTU figure alone cannot establish a good match. Room area matters alongside insulation, sun exposure, ceiling height, air leakage, and how many people or heat-producing appliances are usually present. A unit that is too large may cycle frequently, while one that is too small may run hard without reaching the desired temperature. Use a manufacturer’s coverage guidance as an initial screen, then ask for a load calculation for a permanent installation. The 12,000 BTU models in this roundup are not automatically interchangeable just because their nominal capacity matches.
Should I choose a higher SEER2 rating over a lower-rated system?
A higher SEER2 rating can indicate better seasonal cooling efficiency under the rating conditions, but it should not be the only reason to choose a system. Compare units that are sized for the same job and have compatible, clearly stated ratings. Heating performance, local climate, installation quality, and how often the system runs can shift the real-world result. Ask for heating data as well if winter comfort is part of the purchase, since SEER2 describes cooling rather than the full year-round picture. A well-matched system with sound installation can be a better decision than a higher-rated unit that is poorly suited to the home.
Do I need a central heat pump if my home already has ducts?
Existing ducts make a central system a plausible option, but they do not guarantee an easy or suitable replacement. The ducts should be checked for leaks, sizing, insulation, and airflow, and the equipment must be matched to the home’s heating and cooling load. You will also need to confirm that the air handler, outdoor unit, controls, and electrical supply work together as a system. A ductless unit may still be a better answer for a room that the current duct layout serves poorly, while a portable option can suit temporary or rental needs. Have an HVAC professional review the ductwork and system configuration before buying.
What should I check before buying a heat pump for a cold climate?
Look for published heating capacity and efficiency at low outdoor temperatures, plus the unit’s stated operating range. Ask whether the system needs supplemental heat during local cold snaps and how that backup will be powered and controlled. A rating focused on seasonal cooling does not answer whether the heat pump can meet winter demand. Also check the installer’s experience with cold-climate heat-pump design, since equipment selection, refrigerant lines, airflow, and commissioning all affect performance. Compare those details with your home’s heating load before treating a general heating claim as proof of suitability.
Conclusion
For most buyers choosing a permanent single-zone system, my best overall pick is the Daikin Entra R32 18,000 BTU mini-split, especially when brand support and a dedicated heat-pump setup are priorities. The Temprium 12,000 BTU mini-split is my value-oriented choice for shoppers drawn to its stated 22 SEER2, provided its capacity and installation requirements match the space. For a premium whole-home project, I would compare the Senville 3-ton inverter central system with the Goodman central options and have a professional confirm the right equipment pairing and load. Beginners who want to avoid permanent HVAC work may prefer a portable model such as the Midea Duo, while renters should also compare the other portable picks against their room and window setup. For a small room, start with the Garvee 9,000 BTU mini-split; for a larger single zone, examine the Senville LETO 24,000 BTU—but confirm sizing before ordering. The best choice is the one that fits your climate, building, and installation plan, not simply the unit with the biggest capacity or the longest feature list.
