Mini-split air conditioners are the perfect solution for your home. They’re inexpensive to run, easy to install, and require only a small amount of space, making them ideal for homes of any size.
While mini split air conditioners are much more energy-efficient than a traditional system, they still need power to run. The amount of energy can vary quite a bit between different brands and models. Understanding how much power your mini split AC uses will help you determine if it’s worth making the switch or not.
If you’ve ever wondered about the power consumption of a mini-split air conditioner, you’ve come to the right place.
Factors Determining Energy Usage in Mini-Split Systems
- Heating & Cooling Load
The amount of energy needed by a mini split system to heat or cool a space is called its heating or cooling load. The heating and cooling load of a mini-split system is affected by the size of a house – the bigger the house, the higher the load.
- The Outdoor Temperature
The temperature outside your home will affect the efficiency of your mini split air conditioner. As the outdoor temperature increases, the compressor in your AC unit has to work harder to cool the air inside your home.
- The Number Of Mini Split Units
As you may expect, the more mini split systems you have, the more energy you’ll use. In larger homes, more units may be required to maintain a stable temperature.
- BTU Of The Systems
BTU, or British Thermal Unit, is a measure of energy. One BTU refers to the amount of energy required to increase the temperature of a pound of water by 1° F. It is most frequently used when talking about heating and air conditioning units.
How Many Watts Does a Mini Split System Use?
If you find yourself wondering how much your new mini split AC may cost to run, check out our handy table below.
|Mini Split BTU||Wattage||US Average per kWh||Cost Per Hour|
|6,000||1,758 W||13.19c||Costs $0.23 per hour|
|8,000||2,344 W||13.19c||Costs$0.30 per hour|
|10,000||2,930 W||13.19c||Costs $0.31 per hour|
|12,000||3,516 W||13.19c||Costs $0.46 per hour|
|14,000||4,102 W||13.19c||Costs $0.53 per hour|
|18,000||5,725 W||13.19c||Costs $0.74 per hour|
|21,000||6,154 W||13.19c||Costs $0.80 per hour|
|23,000||6,740 W||13.19c||Costs $0.88 per hour|
|24,000||7,033 W||13.19c||Costs $0.91 per hour|

How To Calculate The Power Your Mini Split Is Using
There are two common ways to calculate the power your mini split is consuming
- .Check the manual. Before chucking your manual in the kitchen drawer, never to be seen again, take a look at the wattage. This will tell you exactly how much power your unit is consuming.
- .Alternatively, if you know the BTU of your mini split, simply divide the BTU by the EER.
Eg. BTU of 6,000 / EER 10 = 600W
How To Save Money When Using Mini-Splits
Use the following tips to ensure you are keeping those costs down when running your AC.
Focus on Efficiency: Understand SEER
SEER is the standard measurement of cooling efficiency for air conditioners. SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER rating, the more efficient the air conditioner is.
Naturally, the more efficient the mini-split is at cooling your home, the lower the cost.
Focus on Efficiency: Understand EER
EER stands for Energy Efficiency Ratio, another measurement of cooling efficiency. The higher the number, the more efficient the air conditioner. When it comes to comparing different air conditioners in terms of energy efficiency, the EER is crucial.
So what’s the difference between EER and SEER? SEER considers the efficiency across an entire season, while the EER is a conventional efficiency measure of an AC unit.
Check the Energy Star Rating
The Energy Star is a joint program of the US Environmental Protection Agency and the US Department of Energy, helping us all save money and protect the environment through energy-efficient products and practices.
The Energy Star label is on products that have been independently certified to use at least 15% less energy than standard products. Selecting a mini split with an Energy Star rating will ensure your AC is more energy-efficient, helping save you money.
Maintain Your Unit
Keeping your unit regularly maintained will save you money in the long run. Regular maintenance will keep your unit running longer, keeping it working as efficiently as possible.
Don’t touch the dial! Don’t forget cooling a room takes time, and constantly fiddling with the temperature dial substantially reduces the efficiency of your unit.
