Do Mini Splits Use a Lot of Electricity?

As energy costs continue to rise, many homeowners are rethinking how they cool and heat their homes. 

Traditional HVAC systems are often bulky and inefficient—especially in older models. In contrast, ductless mini-split systems have gained popularity as a flexible, energy-efficient alternative.

But a common question remains - Do mini-splits use a lot of electricity?

Do Mini-Splits Use a Lot of Electricity?

The short answer is no—mini-splits do not use a lot of electricity, especially when compared to traditional central air conditioning systems. 

In fact, ductless mini-splits consume 30–50% less energy on average than central A/C units. Thanks to their modern design and advanced components, mini-splits have become a go-to solution for energy-conscious homeowners.

Traditional HVAC systems often rely on outdated technology, leaky ductwork, and a one-size-fits-all cooling approach. In contrast, mini-splits offer more precise control and smarter energy use, which leads to significantly lower utility bills.

Why Mini-Splits Don’t Use a Lot of Electricity

Mini-splits are packed with features that naturally keep energy use low. Here’s why:

1. Inverter-Driven Compressors

Unlike old-school central A/C compressors that constantly turn on and off, inverter-driven mini-split compressors adjust their speed to match the cooling demand. 

This results in more stable temperatures and far less energy waste.

2. Higher SEER Ratings

Seasonal Energy Efficiency Ratio (SEER) ratings measure how efficiently an air conditioner operates.

Mini-splits often range from 15 to 26+ SEER, while most central ducted systems hover between 13–18 SEER. A higher SEER means less electricity needed to cool the same space.

3. No Major Ductwork

Central HVAC systems lose up to 30% of energy through duct leaks and inefficiencies.

Mini-splits avoid this issue altogether by using a direct line from the outdoor condenser to the indoor unit, reducing losses significantly.

4. Zoned Temperature Control

With mini-splits, each indoor unit operates independently. 

You can cool only the rooms you’re using, rather than wasting energy on the entire home. This zoning flexibility results in huge efficiency gains from mini-splits.

5. Proper Sizing and Installation

A correctly sized and professionally installed mini-split system performs efficiently. Combine this with good insulation and you’ll see a real difference in your monthly energy costs.

How Klima Saves Electricity

While mini-splits are energy-efficient by design, using a smart thermostat like Klima takes your savings to the next level. 

Klima works specifically with ductless A/C systems like mini-splits, enhancing their efficiency through smart automation, remote access, and real-time energy monitoring.

What is Klima?

Klima is a smart thermostat designed for ductless A/C systems like mini-splits, window and portable A/C systems. 

Klima transforms ductless HVAC units into smart, connected devices that you can control directly from your smartphone. 

With Klima, you gain convenience, automation, and most importantly—real energy savings of up to 30% from your mini-split bills.

Klima’s Key Benefits

1. Boost Convenience

Control your mini-split anytime, from anywhere using the Boldr Energy app.

2. Automate Climate Management

Klima learns your routines and adjusts your mini-split’s temperature accordingly for maximum comfort and efficiency.

3. Reduce Energy Consumption

Using Klima’s energy-saving smart features, you are able to reduce the electricity use of your mini-split, especially during peak demand seasons.

Klima’s Smart Features

1. Remote Access

Turn your mini-split on/off from anywhere, using Klima’s Remote Access feature.

2. Cost Monitoring

With Klima you are able to track your mini-split’s real-time energy use and get bill predictions. Klima helps users cut up to 30% off their cooling costs.

3. Smart Scheduling

Set room-specific schedules where a mini-split and Klima is located, for optimal comfort and energy savings throughout the day.

4. Smart Zoning

Tailor different climate settings in each room where a Klima and mini-split is installed—no more wasting energy in unused spaces.

5. Open Window Detection

Klima turns off your mini-split system if it detects an open window, helping prevent unnecessary energy loss.

6. Health Monitoring

Get maintenance reminders and alerts, through the Boldr Energy app, if your mini-split system isn’t working efficiently, prolonging its lifespan and performance.

7. Guardian Mode

Using Klima’s Guardian Mode, your family members and guests are able to control the temperature of your mini-split with the limits you have set.

8. Location-Sensing Technology

Using geofencing technology, Klima shuts down your mini-split system when no one's around and prepares your home climate depending on occupancy.

Smart Home Integration

Klima works with all mini-split and ductless A/C brands. Klima is also compatible with Google Home, Google Assistant, and Amazon Alexa for full smart home compatibility and voice control.

Conclusion

Ductless mini-splits are a smart choice for homeowners looking to reduce their energy bills without sacrificing comfort. 

They use significantly less electricity than traditional HVAC systems, due to inverter compressors, high SEER ratings, minimal ductwork, and zoned control.

Pairing a mini-split with a smart thermostat like Klima amplifies those savings. With intelligent automation, real-time energy monitoring, and full remote control, Klima ensures your system runs efficiently—and only when it needs to.
