Our Top Picks at a Glance

  • Best OverallDELLA Versa Series 36000 BTU 19 SEER2 Cools Up to 2500 Sq.Ft Mini Split AC Work with Alexa, Energy Efficient Ductless Inverter System with 3 Ton Heat Pump Pre-Charged and 16.4ft Installation Kits

    DELLA Versa 36000 BTU Mini Split AC

    8.1/10

    This DELLA Versa Series model is best suited to shoppers planning a ductless system for a large room, open area, or similar space where the listed coverage of up to 2500 sq. ft. is appropriate. Its 36000 BTU capacity and 3 ton heat pump configuration place it in a higher-output mini split class, while the 19 SEER2 rating gives buyers a concrete efficiency spec to compare against other systems. We also like that the listing includes Alexa compatibility and a 16.4 ft installation kit, since those details help clarify both control options and what is packaged with the unit. The main trade-off is that this is not a simple plug-in appliance; as a pre-charged ductless inverter system, it still calls for proper installation planning, wall placement, line routing, and electrical compatibility checks before purchase.

    Pros

    • Cools spaces up to 2500 sq.ft for broader room coverage.
    • Works with Alexa for convenient voice control.
    • Includes a pre-charged ductless inverter system with a 16.4 ft installation kit.

    Cons

    • It is a premium-end mini split, so the upfront commitment may be higher than a basic window unit.
    • The 16.4 ft installation kit can be limiting if your setup needs a longer line run.
    • Alexa and inverter features add convenience, but they may require a bit more setup than a simple plug-in unit.

  • Best ValueDELLA Vario Series 9000 BTU Mini Split Air Conditioner, Work with Alexa, 20 SEER2, Energy Star, 0.75 Ton, Cools Up to 400 Sq.Ft, Ductless Inverter System, Heat Pump Pre-Charged and 16.4ft Kits

    DELLA Vario 9000 BTU Mini Split Air Conditioner

    8.0/10

    This DELLA Vario Series 9000 BTU mini split is a sensible fit for a single room, studio, office, or similar area where the listed coverage of up to 400 sq. ft. matches the space. The public listing points to a 0.75 ton ductless inverter system with a heat pump, so it is aimed at users who want a fixed wall-mounted solution rather than a portable unit. We like that the key efficiency details are stated clearly: 20 SEER2 and Energy Star are both listed, and Alexa compatibility may appeal to buyers who already use voice or app-based smart home controls. The included pre-charged setup and 16.4 ft kit are useful to know when planning placement. The main trade-off is installation complexity: a ductless mini split is not a simple plug-in appliance, and the line-set length and room-size rating should be checked carefully before choosing it for a larger or awkwardly laid-out space.

    Pros

    • Works with Alexa for voice control and fits ductless home cooling setups.
    • Cools up to 400 sq.ft. with a 9000 BTU, 0.75 ton inverter system.
    • Includes a pre-charged heat pump and 16.4 ft kit for installation.

    Cons

    • A 9000 BTU unit is sized for smaller spaces, so it may not suit larger rooms.
    • Ductless mini split systems can take more planning and setup than a simple window AC.
    • Alexa and inverter features may add convenience, but they also make this a more premium option.

  • DELLA Motto Series 18000 BTU Wifi Enabled Mini Split 19 SEER2 Cools Up to 1000 Sq.Ft, 208-230V, Works with Alexa, Air Conditioner & Heater with Pre-Charged Heat Pump (R32 Refrigerant)

    DELLA Motto Series 18000 BTU Mini Split

    7.8/10

    This DELLA Motto Series mini split is a fit for shoppers looking to add ductless climate control to a larger room, studio, garage-style space, or open living area where the listed coverage of up to 1000 sq. ft. makes sense. Its 18000 BTU capacity, 19 SEER2 efficiency rating, and heat pump design give it year-round utility as both an air conditioner and heater, while WiFi support and Alexa compatibility are useful for buyers who want app or voice control rather than relying only on a wall control or remote. The listing also notes R32 refrigerant and a pre-charged heat pump, which are important details for installation planning. The main trade-off is that this is not a casual plug-in appliance: it is specified for 208-230V power and, like other mini split systems, should be evaluated with the installation location, electrical setup, and coverage needs in mind before purchase.

    Pros

    • 18000 BTU output is suited for cooling spaces up to 1000 sq. ft.
    • Wifi enabled control works with Alexa for convenient adjustments.
    • The unit includes an air conditioner and heater with a pre-charged heat pump.

    Cons

    • Installation is more involved than a standard window AC and usually suits buyers who want a permanent setup.
    • The 208 to 230V power requirement can make it less convenient for spaces without the right electrical setup.
    • Wifi and Alexa features add convenience, but they can also mean a bit more setup and app learning.

  • DELLA Econo Series 16500 BTU Mini Split Air Conditioner 17 SEER2 Cools up to 1000 Sq. Ft, Works with Alexa, Wifi Enabled AC & Heater Ductless Inverter System with Heat Pump, 16ft Installation Kit

    DELLA Econo Series 16500 BTU Mini Split Air Conditioner

    7.7/10

    This DELLA Econo Series mini split is a fit for homeowners or renovators who want a ductless system for a larger room, studio, garage workspace, or open area within its stated coverage of up to 1000 sq. ft. The listing specifies 16500 BTU capacity and a 17 SEER2 efficiency rating, which gives shoppers useful anchors for comparing it with other mini split options. It also combines air conditioning with a heat pump, so it is positioned as a cooling and heating system rather than a cooling-only unit. WiFi support and compatibility with Alexa may appeal to buyers who prefer app or voice-enabled controls, and the included 16 ft installation kit is a helpful detail to note when planning placement. The main trade-off is installation planning: ductless inverter systems are not simple plug-in appliances, and the included line length may not suit every room layout without additional work or parts.

    Pros

    • Cools up to 1000 sq. ft. with a 16500 BTU mini split system.
    • Includes WiFi control and works with Alexa for added convenience.
    • Comes as a ductless inverter system with heat pump and a 16 ft installation kit.

    Cons

    • Requires a fairly involved installation, so it is not a simple plug-and-play window unit.
    • WiFi and Alexa control add setup steps, which may feel unnecessary if you prefer basic manual controls.
    • The ductless mini split format and installation kit make it a bigger upfront project than portable cooling options.

  • DELLA Hyper Heat 18,000 BTU Wifi Mini Split, Work with Alexa,Energy Star 208/230V 22 SEER2 Cools Up to 1000 Sq.Ft Inverter AC with 1.5 Ton Pre-Charged Heat Pump & 16.4ft Installation Kits

    DELLA Hyper Heat 18000 BTU Wifi Mini Split

    7.6/10

    This DELLA mini split is a fit for shoppers looking to condition a larger single zone, such as an open living area, garage workspace, or addition, where a listed coverage of up to 1000 sq. ft. is appropriate. The listing points to an 18,000 BTU, 1.5 ton inverter system with a pre-charged heat pump, plus WiFi control and Alexa compatibility for app or voice-based adjustments. We also like that the title specifies Energy Star status and a 22 SEER2 efficiency rating, which are useful details when comparing ductless options. The main trade-off is installation complexity: it is a 208/230V mini split and includes a 16.4 ft installation kit, so buyers should plan around electrical requirements, line-set routing, and whether professional installation is needed for their space.

    Pros

    • Includes WiFi control and Alexa compatibility for convenient operation from your phone or voice assistant.
    • Provides 18,000 BTU cooling capacity and is rated to cool spaces up to 1,000 sq. ft.
    • Comes as a pre-charged heat pump system with a 16.4 ft installation kit included.

    Cons

    • Installation is more involved than a portable unit and may call for professional HVAC help.
    • The setup uses 208/230V power, so it is not a simple plug-and-play fit for every home.
    • Its mini split format takes wall space and is less portable than a window or floor AC.

  • DELLA Umbra Series 12000 BTU Mini Split AC Wifi Enabled Work with Alexa 17 SEER2 Energy Saving Cools Up to 550 Sq.Ft & Pre-Charged Heat Pump Ductless Inverter System (R32 refrigerant)

    DELLA Umbra 12000 BTU Mini Split AC

    7.5/10

    This DELLA Umbra Series model is a fit for shoppers looking to condition a single room or defined area rather than add central air, with the listing stating 12000 BTU capacity and coverage up to 550 sq. ft. It combines ductless inverter operation with a heat pump, so it is aimed at year-round room comfort where a mini split setup makes sense. The public listing also highlights WiFi control, Alexa compatibility, a 17 SEER2 efficiency rating, R32 refrigerant, and a pre-charged system, giving buyers several concrete points to check against their installation needs. A practical trade-off is that the supplied listing information does not include details such as noise levels, line-set length, warranty terms, or installation requirements, so those should be verified before purchase.

    Pros

    • Cools spaces up to 550 sq. ft. with 12,000 BTU capacity.
    • WiFi enabled design works with Alexa for app and voice control.
    • Includes a pre-charged heat pump ductless inverter system with R32 refrigerant.

    Cons

    • Requires wall-mounted ductless installation, so it is not as simple as a portable AC setup.
    • Wi-Fi and Alexa control add convenience, but they can also mean a bit more setup and app learning.
