The Best Mini Splits for 2023

Ductless mini splits provide many benefits over other air conditioning systems. For one, they are easier and cheaper to install than traditional HVAC systems. This is especially true for multiple rooms that require heating or cooling. Secondly, they are much more efficient than other air conditioners. 

In this guide, we cover everything you need to know about mini splits, and provide our recommendations of the best mini splits for each category. 

How Do Ductless Mini Splits Work?

Ductless mini-splits are cooling and heating systems composed of two units: an indoor unit and an outdoor unit. Their name comes from the fact that the compressor and refrigerant coils are split between the inside and outside of the house. 

Both units are connected by a narrow conduit that circulates the refrigerant and delivers it to the coils housed outside.

How to Choose the Best Mini Split for your Needs

Shopping for a mini split involves more than just looking at the capacity and price sticker. These are the five factors you should consider to ensure you get the best possible mini split for your home.

1. Zones

How many rooms or spaces do you need to heat and cool? A single zone unit is designed for one room or space, whereas a multizone unit can accommodate multiple rooms.

2. Sizing

A mini split’s cooling and heating capacity is measured in BTUs (British Thermal Units). The higher the BTU, the larger the space it can handle. To determine the right size for your home, you need to take into account both the physical size and heat load of the zones.

Refer to our handy Mini Split Sizing Guide to make the process more convenient.

3. Placement

For each room, map out the installation area for the mini split. This will determine what type of mini split you need. Wall and floor mounted units are typically the easiest to install but stand out and take up room, whereas concealed duct and ceiling cassette models are more inconspicuous and maximize the space.

4. Voltage

Most single-zone mini splits typically run on a 110-120 volt plug, the standard wiring for most homes. However, multi zone mini splits may need 220-240V. When choosing a mini split, make sure your home has the right voltage.

Check out our wiring guide for mini splits.

5. Energy efficiency

To get the most efficient mini split for your budget, look for these things that impact energy efficiency:

☑ EnergyStar certification

An EnergyStar certified mini split means it uses up to 60%  less energy than standard heating and cooling systems.

☑ EER and SEER rating
EER stands for Energy Efficiency Ratio and is an objective measurement of how efficiently a unit is engineered to run. SEER stands for Seasonal Energy Efficiency Ratio and is a measurement of how efficiently a unit will operate over the course of one cooling season. 

On January 1, 2023, this was changed to SEER2 which more accurately measures the real-world energy consumption of mini splits and heat pumps. Check out our SEER2 guide to determine the minimum rating for your region.

☑ Refrigerant

In 2023, the Environmental Protection Agency started phasing out R410-A, a refrigerant commonly used in AC and heat pumps. This has been replaced by A2L refrigerants that are more efficient and eco-friendly. 

To future-proof your system, look for a mini split that uses A2L refrigerants like R32. 

☑ Inverter technology

Inverters can lower the power consumption of devices based on demand. Instead of running full blast all the time, an inverter mini split is able to adjust its consumption automatically to meet the desired temperature, then dial back its operation. This lowers electrical consumption and greatly extends its lifespan.

Here’s our list of the best inverter mini splits.
