What is The Most Energy Efficient Mini Split Air Conditioner
Mini split units are very good heating and cooling units that are known for their efficiency and DIY installs.

While most units are more efficient compared to big traditional home HVAC systems some units are more efficient than others.

What Makes a Mini Split 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 ductwork that has been traditionally used to blow air into a home makes a more efficient system.

Mini split units also have inverter-driven compressors that speed up and slow down depending on the demand.

This means they don’t shut off completely as traditional HVAC compressors do.

The biggest demand for energy with an HVAC unit is during startup. Traditional compressors will draw a large amount of power during the 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 can 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.

The higher the SEER rating, the more energy efficient a unit is.

A SEER rating is based on the output a system has, over a heating or cooling season, divided by the total electric energy input.

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.

Find the SEER rating number when looking for the most efficient mini split system. The higher the number, the more efficient the system is.

Many traditional HVAC systems have a 10-16 SEER rating, with 14-16 SEER often installed on many 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.

Be sure to read the listings below for any changes in SEER rating and what is included in any kit.

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 down electrical bills.

Another factor to consider when buying a unit is the build quality and warranty a package comes with.

Preferences can vary from person to person how good a brand is.

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 installation can run up costs 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 12-16 SEER rating, with 14-16 SEER the most common.
