What Does It Cost to Run a Mini-Split?

Over the last decade, mini-split systems have emerged as a popular choice for home climate control. Offering efficient heating and cooling solutions and easy installation, the cost to run a mini-split may surprise you! 

From initial purchase and installation to ongoing maintenance and energy consumption, the financial aspects of running a mini-split can vary. Whether you’re weighing the pros and cons of different HVAC systems or looking for insights to optimize your existing setup, read along as we discover the costs behind running a mini-split.

Factors affecting the Cost to Run a Mini-Split in Olympia, WA

Factors Affecting the Cost

One of the biggest factors influencing the operational cost of a mini-split is its energy efficiency. Units with higher Seasonal Energy Efficiency Ratio (SEER) ratings consume less energy, resulting in lower electricity bills over time. On average, ductless mini-splits have SEER ratings around 16-22+, which is higher and more efficient than central HVAC systems, with ratings around 14-21. This means that it costs less energy (and money) to reach the ideal temperature in your home.

The climate and weather conditions of the region where the mini-split operates significantly impact its running costs. For instance, units in regions with extreme temperature fluctuations may have increased energy consumption. In the Pacific Northwest, although we have some extreme days, most cold and heat waves are mild. That means a ductless mini-split system doesn’t have to work too hard to keep up.

Your mini-split’s monthly costs depend heavily on how often and for how long you use it. Homes or businesses that rely on mini-splits seasonally will see lower costs compared to those using them year-round. However, those currently using electric baseboard heaters or central HVAC systems might find year-round mini-split operation for both heating and cooling more cost-effective.

Choosing the proper size mini-split system plays a critical role in determining its operational cost. Oversized units may cycle on and off frequently, resulting in energy wastage, while undersized units may struggle to meet heating or cooling demands efficiently. To ensure you find and install the correctly sized mini-split, it’s best to work with a ductless professional.

Calculating Energy Consumption

British Thermal Units (BTUs) are used to measure the heating and cooling capacity of mini-split systems. Calculating the appropriate BTU rating based on the size and requirements of the space ensures optimal energy usage and cost-effectiveness. Again, this is something a professional mini-split installer can help you determine.

The SEER rating indicates the energy efficiency of the mini-split system. Higher SEER ratings signify greater efficiency, translating to lower operating costs over time.

Average Cost of Operation

Mini-split owners can expect varying monthly and annual expenses depending on factors such as energy rates, usage habits, and system efficiency. On average, the operational cost of running a mini-split in Olympia, WA ranges from $50 to $150 per month, with annual expenses averaging between $600 and $1,800.

Compared to traditional HVAC systems, mini-splits offer potential cost savings due to their zonal heating and cooling capabilities.

Ductless mini-splits are more efficient than central air conditioning systems. Central ACs use ductwork to push air throughout the home, but the ductwork itself is a common place for leaks. In fact, the Energy Star reports that 20-30% of air is lost due to leaks, holes, or improperly sealed ducts. 

By only conditioning occupied spaces, without ductwork, mini-splits reduce energy wastage, resulting in lower utility bills. In fact, people have reported saving up to 50% on their monthly bills.

Tips for reducing the Costs of a mini split

Tips for Reducing Operational Costs

Routine ductless maintenance, including filter cleaning, coil inspection, and refrigerant checks, ensures optimal performance and energy efficiency, reducing long-term operational costs. You can typically do filter cleanings on your own, but consider hiring a ductless professional for occasional system checks.

When it comes to efficient thermostat settings and temperature management techniques, it’s best to ’set it and forget it’. Your mini-split tends to operate more efficiently when you aren’t changing the temperature setting frequently. To make this work properly, set the mode to heating or cooling, find the temperature that is comfortable, and then set your fan speed to AUTO. Direct warm air to the floor so that your mini-split variable-speed fan automatically adjusts and maintains that temp. 

Unlike traditional heating where you make adjustments when you leave the house and go to bed, your mini-split is far better off left on the setting described above.

Air sealing your home is a must to keep your indoor temperature controlled and cost-effective. Properly insulate and weatherproof doors, windows, and walls to prevent heat loss or gain, allowing your mini-split to operate more efficiently.

Environmental Impact of a Mini-Split

By reducing energy consumption and greenhouse gas emissions, mini-split systems contribute to environmental sustainability and combat climate change.

Exploring renewable energy sources such as solar panels or geothermal heating and cooling systems can further enhance the eco-friendliness of mini-split setups, reducing reliance on non-renewable resources.
