Answer:
The electricity a mini split uses depends on its size and efficiency, but on average, a 12,000 BTU unit consumes about 0.9 to 1.5 kWh per hour under typical operation. From our decades in the HVAC industry, we’ve observed that larger units like a 24,000 BTU mini split might use around 2 to 3 kWh per hour. The actual consumption depends on factors like the outdoor temperature, indoor settings, and how often the system cycles on and off. For homeowners, this translates to significantly lower energy costs compared to traditional heating and cooling systems when sized and installed properly.
More On “How Much Electricity Does A Mini Split Use?”
Mini splits are widely regarded as one of the most energy-efficient HVAC solutions, thanks to their inverter technology. Unlike traditional systems that turn on and off at full power, mini splits adjust their compressor speed to meet the exact demand of the space. This means they consume less electricity during operation, especially when maintaining a steady indoor temperature. Based on our experience, many homeowners notice a significant drop in their energy bills after switching to mini splits, particularly during peak heating or cooling seasons.
The actual electricity usage also depends on the SEER (Seasonal Energy Efficiency Ratio) rating of your mini split. Higher SEER ratings indicate better efficiency, and while units with higher ratings might have a slightly higher upfront cost, they more than make up for it in long-term energy savings. For instance, a mini split with a SEER rating of 20+ will likely use far less electricity than one rated at 16. In our professional opinion, investing in a high-efficiency model is always worth it if energy savings and environmental impact are priorities.
Another important consideration is how the system is used. Setting the temperature too high in the winter or too low in the summer can cause the unit to work harder, increasing electricity consumption. We always recommend setting a consistent, moderate temperature and using zoning features effectively if you have a multi-zone system. These strategies not only save electricity but also maximize the comfort and longevity of your mini split.
