We’ve rounded up the best ductless air conditioners that won’t disappoint, including models from Gree, Bosch, and Emerson. That means rave-worthy features such as night modes to make sure nothing disturbs your shut-eye and smart-enabled systems that will let you bark orders from a remote smartphone. Thankfully, the best ductless AC won’t have to thin out your wallet too much either, as single-zone systems set you back around $800. On the flip side, if you’ve got a bigger budget, multiple zone systems will dish out a cool supply of air to several rooms at once, usually for the price of a few grand. Whether it’s a single zone or multiple zone systems you go for, the best ductless air conditioners (known as mini splits too) shouldn’t drain your energy. That’s why we’ve focused our attention on models that have a good SEER rating. While you’re digging through our best ductless air conditioner reviews, you’ll also want to remember that these machines are a permanent cooling solution, so you won’t be able to switch its place in the house once it’s knocked into place.

What is a ductless air conditioner, and how do they work?
A ductless air conditioner does pretty much the same job as a traditional central air conditioner, just without the ducts. If you’re wondering how that works exactly, the appliance takes the warm air and moisture from your room and runs it over cold evaporator coils. As happens in a regular central air conditioner, the heat is absorbed into the coil and converted into cold air by a refrigerant. In return, the machine emits a blast of cool air into your room. But where does the hot air go? Well, while a traditional AC unit channels the hot air through your home’s ducts and outside, the ductless air conditioner unit is connected to an outdoor unit instead, which dumps the heat outside your home without the need for installing ducts. Aside from that, the main difference between these two types of air conditioners is that a ductless air conditioner unit usually works on one room (or a couple, if it’s a multiple zone system), while the ducts associated with the central air conditioner divvy out cool air throughout an entire house.
How to buy the best ductless air conditioner for your home
With so many ductless air conditioner models on the market, it may seem tricky to sift through to find the best one for you. Start by picking out a reputable brand such as Bosch or Daikin and then take a look at the features. If you have multiple rooms in need of some TLC, such as a small apartment, a multi-zone design will let you cool down more than just one space. After you’ve decided on a single zone or multiple zone ductless air conditioner, perhaps the most important thing to look out for is a powerful model with high British Thermal Units (BTU). This is especially important if you’re handling a large space or if you live in a hot climate or poorly insulated home, because the higher the BTU, the more power you’ll have to keep the temperature constant against these higher demands. After power, you’ll also want to consider other features that matter the most to you. If your home is prone to getting cold in the winter months, for instance, you may want to pick a model that will double up as a heater to save money on forking out for a separate heater appliance. Likewise, if you’re looking to limit any disturbances at night, a quieter model or one with a sleep mode will come in handy.
