Ductless mini splits are gaining popularity as an energy-efficient solution for heating and cooling homes. But if you’re considering one for your home, you might be wondering how much electricity they actually use. Compared to traditional systems, mini splits can be a more cost-effective and efficient option, but the exact energy consumption depends on several factors.
How Energy Efficient Are Mini Splits?
Mini splits are designed to be highly energy efficient, often outperforming conventional heating and cooling systems. Their efficiency is measured using a Seasonal Energy Efficiency Ratio (SEER) for cooling and a Heating Seasonal Performance Factor (HSPF) for heating. Many mini splits have SEER ratings of 20 or higher, making them significantly more efficient than older central air systems.
Unlike traditional systems that rely on ductwork, mini splits deliver air directly into a room, reducing energy loss. Duct losses can account for up to 30% of energy consumption in a home, so eliminating this factor helps lower electricity usage.
How Much Electricity Does a Mini Split Use?
The electricity consumption of a mini split depends on factors like the unit’s size, efficiency rating, and how often it’s used. On average, a single-zone mini split typically consumes between 500 to 1,500 watts per hour while running. This is much lower than many traditional systems, especially when compared to electric furnaces or baseboard heaters.
Factors that influence energy usage include:
- Climate – Homes in extreme temperatures may see higher electricity use as the system works harder to maintain comfort.
- Insulation and Home Size – Well-insulated homes require less energy to maintain a consistent temperature.
- Usage Patterns – Running a mini split at a consistent temperature rather than frequently adjusting settings helps optimize efficiency.
- Number of Zones – A multi-zone system may use more electricity overall, but it still offers targeted heating and cooling that prevents wasted energy.
Are Mini Splits More Cost-Effective Than Traditional Systems?
In most cases, installing ductless mini splits offers lower operating costs compared to traditional systems, especially if you’re upgrading from an older, inefficient unit. Because they use inverter-driven compressors, they adjust power usage based on demand rather than running at full capacity all the time. This means they avoid the frequent starts and stops that drive up electricity usage in conventional systems.
