How We Picked the Best Mini Splits

When recommending mini splits, we take six features into account.

 

Efficiency

Ductless mini splits are more efficient than regular air conditioners and heaters because of their advanced controls and inverter-driven compressors. SEER2 and EER2 ratings measure how well a mini split cools your space for the energy it uses. On the other side, the HSPF rating measures how efficiently a mini split provides heat. We study these ratings carefully and only recommend the most efficient units for your money.

 

Features

The best ductless air conditioners and heaters come with a vast array of features that simplify useability, durability, and convenience. From enhanced temperature controls that allow rapid heating and cooling, to airflow adjustments, to self-cleaning capabilities and mounting options, mini split manufacturers are constantly competing to add better functionality to their products. We comb through these features to determine what's useful and what's mere marketing before making our recommendations.

 

WiFi Capability

Internet connectivity is fast becoming a deciding factor when it comes to choosing mini splits. Despite it being 2024, not every manufacturer has gotten on board the WiFi train. Those that have are quickly realizing that most people love the convenience and remote capabilities offered by WiFi.

For example, you can adjust your home's temperature from across the globe to save energy. When coming back from work, you can use your smartphone to start heating up your home so it's warm and comfortable upon arrival. If you are on the fence between two mini split systems, knowing that one has WiFi could make your choice easier. 

 

Heating Capability

The best mini splits provide both heating and cooling. When a mini split is in heating mode, it's referred to as a heat pump.

Traditionally, ductless mini splits weren't able to provide heat if the outdoor temperature fell below a certain point. In recent years, that point has gotten lower and lower.

Today, some mini split heat pumps will effectively heat even if the outdoor temperature drops to -22 degrees Fahrenheit. This efficient operation at low temperatures is known as low ambient heating, and we take it into account when choosing the best ductless heaters.

 

Warranty

Although worth it for the unmatched comfort they provide, ductless air conditioners and heaters are significant financial investments. After making such a purchase, you want to ensure that you have protection in case something goes wrong. That's why I strongly consider the warranty when evaluating mini splits. If two mini splits seem identical, that extra year of coverage could make all the difference.

 

Overall Value

Overall, ductless mini splits will cost you more than most other types of heaters and air conditioners. Simply put, their efficiency and high-tech operation makes them more expensive to make.

Still, there can be wide price differences even among mini splits, and we take that into account when making our recommendations. If a mini split is expensive but backs up the price with superior performance and features, we would say it's worth it.

On the flip side, you might save money on a poorly-built mini split, but that won't help you if you have to replace it in a few years anyway. Instead of price, value is what we're after.

Mini Split FAQs

What is a Mini Split?

A mini split, formally known as a ductless air conditioner, is a system designed to cool your home without using ductwork. Instead, it consists of an indoor air handler that connects to an outdoor compressor with a refrigerant line set. To cool your space, the air handler removes heat from inside and pumps it outside.

 

Unlike a forced air system, the above process works on a room-by-room basis. However, It's possible to install multiple mini splits throughout a building in "zones." These multi-zone setups enable you to adjust the temperature in each zone separately. Overall, ductless mini splits are more efficient, quiet, and high-tech than forced air systems. there are even ducted models available that directly replace a forced air system. Learn more in our mini split buyer's guide.

Is a Mini Split a Heat Pump?

In addition to cooling, many ductless mini splits also provide heat by reversing the direction of refrigerant flow. The mini split acts like a heat pump, collecting heat from the outside air and transferring it inside your home. Modern mini splits are becoming more efficient and capable of pulling heat from extremely cold outdoor temperatures, even down to -22°F, making them great for chillier climates. Learn more about the difference between mini split heat pumps and air conditioners.

 

What Size Mini Split Do I Need?

What size mini split you need will depend on several factors, including your desired temperature, square footage, insulation, and building age. A professional should do the sizing for you, but you can get a general idea by using our free mini split sizing calculator.

 

 

Shop Mini Splits

 

 

Are Mini Splits Loud?

Unless you are inches away, ductless mini splits are extremely quiet, especially on a low fan speed. Typically, they run at less than 32 decibels. For comparison, a typical forced air system runs at around 60 decibels.

 

Do Mini Splits Run All the Time?

Although you can shut a mini split off, it doesn't make sense from an efficiency standpoint. Mini splits use inverter technology that constantly adjusts output to maintain a consistent temperature and keeps your space perfectly comfortable. As a result, they should be on all the time. Turning the unit off and turning it back on later will only waste energy and raise your energy costs.

 

What Does SEER Mean on a Mini Split?

The Seasonal Energy Efficiency Ratio (SEER) was updated in 2023 to SEER2 and rates the efficiency of ductless mini split air conditioners. It's a ratio of the total cooling output from a piece of equipment in BTU divided by the energy it consumes in watt-hours. The higher this ratio, the better. Learn more about SEER2 and other efficiency ratios and requirements.

 

 

Shop Mini Splits

 

 

Do Mini Splits Dehumidify?

Many mini splits have a setting called "dehumidifying" or "dry" mode, which lowers the fan speed to more effectively remove moisture from the air. Keep in mind that this will only reduce humidity by around 30 percent and is not designed to replace a dehumidifier. Learn more about using a mini split to remove humidity.

 

Do Mini Splits Have Filters?

Like central heating and air conditioning systems, mini splits have filters that trap dust and dirt. These filters are typically located on the indoor unit's front panel and need to be washed or replaced monthly.
