While most units are more efficient compared to most big traditional home HVAC systems some units are more efficient than others.
What Makes a Mini Split Air Conditioner Energy Efficient
Several factors make a mini split energy efficient including being ductless, and more importantly the inverter-driven compressor.
Mini split units are ductless with standard home HVAC duct systems losing on average 25 percent or more of the conditioned air.
Removing duct-work that has been traditionally used to blow air into a home makes a more efficient system.
The biggest demand for energy with an HVAC unit is during startup. Traditional compressors will draw a large amount of power during start and then level off after running a few minutes.
Most big home units turn off and back on constantly in a cycle that uses a lot of energy.
Mini split units with inverter-driven compressors are able to save a lot of energy without heavy up and down spikes.
For these reasons along with better technologies mini split units are very efficient to run.
How To Read the Energy Efficiency of a Mini Split
All HVAC systems have a SEER rating (seasonal energy efficiency ratio) that shows how efficient they are.
Other standards include EER and COP which are not used as much as the SEER rating.
EER or COP is used with HVAC systems but not displayed on mini split units as much as the SEER rating.
When looking for the most efficient mini split system find the SEER rating number. The higher the number the more efficient the system is.
Most traditional HVAC systems have a rating of 10-16 SEER with 14 SEER installed on most new homes.
Mini split systems commonly range from 17-38 SEER depending on the unit.
There are many good units with those below the most energy-efficient we have found.
As always be sure to read the reviews on Amazon, here, or elsewhere to be sure a unit is a good fit for you.

12,000 BTU is rated to heat or cools a space roughly 450 to 550 Sq Ft.
Daikin mini split units work very well heating and cooling while saving energy.
Mitsubishi 12,000 Btu 23.1 Seer Single Zone Ductless Mini Split Air Conditioning System (AC only)
Mitsubishi is a well-known manufacturer of quality mini split systems with good warranties.
They are built to last many years and make some of the most energy efficient units available.
The downside is they cost more but the price can be worth it for those who want a very reliable mini split that also uses less energy.

Installing a mini split is a good way to heat and cool a space along with saving energy.
Besides being better for the environment this can also bring don electrical bills.
Another factor to consider when buying a unit is the build quality and warranted a package comes with.
Preferences can vary from person-to-person how good a brand is.
For example, personally I prefer Daikin and Mitsubishi units with Daikin my go-to brand.
Again this is a preference with many of the other brands working great for many years.
Installation can also be a big factor since many of the high SEER units do not come in a DIY kit.
While they can be installed by a knowledgeable homeowner an HVAC company will likely be needed.
Hiring an HVAC company for install can run up cost making DIY kits very popular.
Most DIY kits have SEER ratings around 17-19 SEER which is still a very good rating compared to a traditional home HVAC system.
Traditional systems have a rating of 12-16 SEER with 14 SEER the most common.
