How to Compare Mini Split Efficiency? - Lowest to Highest SEER Rating + Tips on Power Consumption

Mini splits are known for their good energy efficiency. But, if you're new to mini splits, how do you compare the energy efficiency of a mini split with other types of air conditioners. Plus, there are so many different kinds of mini splits and thus, how do you compare them? This video covers everything you need to know about mini split efficiency and tips on what to expect with regard the power consumption of mini splits.

Nice job explaining mini split efficiency.👍

[@aircondlounge]

Thank you

[@dell177]

Good clear explanation

[@ystebadvonschlegel3295]

Very good explanation.

[@aircondlounge]

Thanks. Glad it does!

[@dollymix5]

Just to make the explanation better. Its written BTU in the package but they really mean BTU/h. I got confuse because of this since BTU is unity of power not energy.

[@davef.2329]

Nice video and explanation. What is the brand of those units shown in the charts you used in this video? Thanks.

[@aircondlounge]

It’s Mitsubishi Electric, US

What is seer2

[@aircondlounge]

SEER2 is a better energy efficiency rating that replaces SEER. It tests a mini split over a cooling season (about 3 months) rather than just dividing the capacity by power. Mini splits produce in 2023 onward will all be using SEER2.

Those poor outdoor units in tiny, cramped space was so painful to look at.

[@davef.2329]

Indeed. That array shown at 9:12~9:16, likely wouldn't last a season as they'd run continuously with the stagnation of airflow/heat exchange..

[@aircondlounge]

That was from my previous project. In the end, they hacked and rebuilt the wall to accommodate the outdoor units.
