Mini Split System Cost: A Comprehensive Guide

Mini splits are one of the most efficient AC systems. Their ductless nature reduces energy losses, and they can even perform both heating and cooling in one convenient package!

That said, one of the most frequent questions we get asked is, “Just how much does a mini split system cost, and is it worth the added price?”

In this detailed guide, we break down the cost analysis, utility expenses, and whether or not mini splits are worth the savings.

What is the Cost of a Mini Split System?

The upfront cost of a mini split system varies based on factors like brand, capacity, and the number of zones it can handle. Prices range from $900 for a basic, single-zone unit to over $5,000 for a multi-zone setup. Top brands might command higher prices due to their reputation for reliability and advanced features.

The price is generally determined by:

1. BTU capacity

This refers to the mini split’s cooling capacity. The higher the BTU, the larger the area it can cool or heat.

2. Single vs multi-zone

Zones refer to the rooms or spaces a mini split can service. This is designated by how many indoor units are included in the package.

A single-zone mini split is designed to cool and heat a single room, and only comes with one indoor unit connected to an outdoor compressor. A multi-zone system can handle multiple rooms. Such systems denoted by the number of indoor units included in the package, such as dual-, triple, or quad-zone systems.

3. Efficiency

The efficiency of mini splits are measured by the SEER rating. This measures the unit’s energy efficiency over the course of a cooling season. This rating is mandated by the US Department of Energy, and the higher the SEER, the more efficient the unit is.

EnergyStar certification is another measure of energy efficiency. Mini splits that carry the EnergyStar label are certified by the EPA to be more efficient than their non-labeled counterparts. While they tend to cost a bit more, they can be up to 30% more efficient, more than making up for their purchase price over the long run.

4. Inverter technology

Inverter technology is a feature that can dynamically adjust the output power of the mini split. 

Rather than operating at full power all the time, it uses a variable compressor that adjusts its speed to reach the desired temperature, before dialing back. This results in a more efficient and quiet mini split.

5. Brand and warranty

Established brands tend to command higher prices, thanks to their established name and reputation for quality. Warranty coverage is also a testament to the manufacturer’s confidence in their product, as mini splits are designed to last for many years. It is critical to make sure the mini split manufacturer has a strong US based presence for tech support and parts in the future.

6. Other features

At the top end of the scale, premium mini split models are distinguished by advanced features. Some offer smart home integration, voice or Wi-Fi control, and even advanced air quality control.

Mini Split Installation Cost 

The installation cost for mini split systems can be significant, but vary widely based on complexity and labor rates in your area. 

In general, a standard single-zone installation typically ranges from $500 and $2,000, while multi-zone setups range from $800 to $2,000 per zone. 

The mini split installation cost is determined by several factors:

Unit placement: Indoor units installed on higher floors require more wiring, conduits and refrigerant lines, thus increasing the cost.

Refrigerant line: this costs $5.00 – $10.00 per linear foot

Wiring: runs $3.00 to $8.00 per linear foot

Electrical upgrade: Older homes may need to have their electrical panel upgraded, which costs $1,100 on average.

Labor cost: This varies based on the location, expertise, and complexity of the installation.

While it might be tempting to DIY your mini split installation to save on labor, keep in mind that you will most likely void your warranty. While portions of the installation can be completed by an avid do-it-yourselfer, the final installation requires a professional with the right tools, know-how, and licenses. 

That being said, there are specialized DIY mini-split systems specifically designed for DIY installation. Such DIY systems include all the necessary parts and accessories, and uses pre-charged line sets and require only basic tools for installation. This is a cost-effective option for the handy homeowner; by eliminating the need for an HVAC specialist, you can reap some pretty significant savings. You can learn more in our guide to DIY mini splits to determine if this is the right system for you. 

Mini Split Running Costs

The primary operating cost of a mini-split system is the electricity it consumes. Mini-splits are renowned for their energy efficiency. Ducts account for up to 30% of the energy losses in a forced air system, making ductless mini splits much more cost-effective than traditional HVAC systems. 

The electricity cost varies depending on the BTU capacity, usage, and local electricity rates. On average, a 12,000 BTU mini split consumes around 1.0 to 1.5 kWh per hour of use. Using the national average electricity rate in the US of approximately $0.13 per kWh, running a 12,000 BTU mini-split for 8 hours a day would cost between $31.20 and $46.80 per month. This is only an estimate and your actual usage costs can vary widely based on usage, electrica rates, temperature set points, insulation, and many other factors. 

The DOE estimates that half of the utility costs paid by American homes goes into heating and cooling. The efficiency of mini splits therefore translates into massive utility savings over the long term, even if its costs more than traditional AC systems to purchase.

Mini Split Maintenance Costs

Maintenance costs can vary based on whether you perform DIY maintenance or hire a professional. Here are some estimated annual maintenance costs:

DIY maintenance: $50 to $100 per year for filter replacements and basic cleaning. It’s recommended to clean the filters at least once a month, and to replace them with a new set if damaged. Check out our guide to Mini Split Cleaning and Maintenance to know more.

Professional maintenance: This is a comprehensive inspection and cleaning by a certified HVAC tech. It is recommended to have a professional inspection done once a year, which can cost between $100 to $300 per visit.

Mini Split Repair Costs

While mini-split systems are generally reliable, as with any home appliance unexpected breakdowns can occur over time depending on usage and upkeep. Repair costs can vary significantly based on the issue’s complexity and whether the system is under warranty. Mini-split systems typically come with a 5 to 10-year warranty on parts, but labor costs may not be covered.

Minor Repairs: $100 to $500

Major Repairs or Component Replacement: $500 to $1,500 or more

Mini Split Cost FAQ

What’s a good price range for a decent, reliable mini split?

When researching mini-splits, seeing systems that cost upwards of $7k can make your head spin and your palms start to sweat, but purchasing a quality unit will go a long way towards cost-efficiency in the long run. 

Decent units start anywhere from $900-$1,000 but don’t be tempted to buy the cheapest unit merely for that reason. You’ll want to buy from a major mini-split heat pump manufacturer, like Daikin, Panasonic, , Friedrich, Mitsubishi, or Fujitsu, as there’s a greater chance the system will function as it should and that parts and warranty service will be available down the line.
