Types of Mini Split Systems

When it comes to mini split AC systems, there are a few different types to choose from. The two main types are ducted and ductless mini splits. Ducted mini splits are connected to a system of ducts that distribute the air throughout the space, while ductless mini splits use individual units to cool specific rooms.

Ducted Mini Splits

Ducted mini splits are a great option for larger spaces or multiple rooms that need to be cooled. These systems are typically more powerful and can distribute air more evenly throughout the space. Ducted mini splits are often more discreet as the main unit is hidden away in an attic or closet, with only the vents visible in each room.

Ductless Mini Splits

Ductless mini splits are perfect for smaller spaces or rooms that need individual cooling. These systems are easier to install and are more energy-efficient since you can control the temperature in each room separately. Ductless mini splits are also a great option for older homes that do not have existing ductwork.

Sizing Your Mini Split System

One of the most important factors to consider when buying a mini split system is the size of the unit. You want to make sure you choose a system that is powerful enough to cool your space efficiently without being oversized and wasting energy.

Calculating BTUs

The British Thermal Unit (BTU) is used to measure the cooling capacity of an AC unit. The higher the BTU, the more powerful the unit. To calculate the number of BTUs you need for your space, you can use this simple formula:

(BTU = Area (in square feet) x 20)

For example, if you have a room that is 500 square feet, the calculation would look like this:

(500 x 20 = 10,000 BTUs)

Factors to Consider

When sizing your mini split system, there are a few other factors to consider besides just the square footage of your space. Things like ceiling height, insulation, and the number of windows in the room can all affect the cooling capacity you need. It’s always a good idea to consult with a professional to help you determine the right size unit for your space.

Energy Efficiency

Another important factor to consider when buying a mini split system is its energy efficiency. A more energy-efficient system will not only help you save money on your monthly energy bills but also reduce your carbon footprint. Look for systems that have a high Seasonal Energy Efficiency Ratio (SEER) and Energy Efficiency Ratio (EER) ratings.

SEER Rating

The SEER rating measures the energy efficiency of an AC unit over an entire cooling season. The higher the SEER rating, the more efficient the system is. In general, mini splits with SEER ratings above 20 are considered highly energy-efficient.

EER Rating

The EER rating measures the energy efficiency of an AC unit at a specific outdoor temperature. This rating can give you a better idea of how well a system will perform in your specific climate. Look for mini splits with EER ratings above 12 for optimal efficiency.


Installing a mini split system is a job best left to the professionals. While it may be tempting to try and install the system yourself to save money, improper installation can lead to a host of problems down the line. A professional HVAC technician will ensure that your system is installed correctly and will provide you with peace of mind knowing that your new mini split will work efficiently for years to come.

Hiring a Professional

When hiring a professional to install your mini split system, make sure you choose a licensed and experienced HVAC technician. They will be able to assess your space, recommend the right size unit, and install the system correctly. Be sure to get quotes from multiple companies and ask for references before making a decision.

DIY Installation

If you are confident in your DIY skills, some ductless mini split systems are designed for easy installation by homeowners. However, keep in mind that DIY installation may void the manufacturer’s warranty and could lead to costly repairs down the line if not done correctly.

Maintenance and Repairs

Like any HVAC system, mini split systems require regular maintenance and occasional repairs to keep them running smoothly. By following a few simple maintenance tips, you can ensure that your mini split system stays in optimal condition for years to come.

Regular Maintenance

To keep your mini split system working efficiently, be sure to clean or replace the filters regularly. Dirty filters can restrict airflow and reduce the system’s efficiency. You should also check the outdoor unit for any debris or obstructions and clean the coils with a soft brush or cloth.

Annual Check-Up

It’s a good idea to have a professional HVAC technician inspect your mini split system once a year to catch any potential issues before they become major problems. They can check the refrigerant levels, test the electrical components, and clean the unit to keep it running smoothly.


The cost of a mini split system can vary widely depending on the size and type of system you choose, as well as the brand and efficiency ratings. While mini splits typically have a higher upfront cost compared to traditional central AC systems, they can save you money in the long run with lower energy bills and reduced maintenance costs.

Upfront Costs

The upfront costs of a mini split system include the price of the unit itself, installation fees, and any additional accessories or equipment you may need. Ductless mini splits are generally more affordable than ducted systems, but the total cost will depend on the size and complexity of your installation.

Operating Costs

Mini split systems are known for their energy efficiency, which can lead to significant savings on your monthly energy bills. By choosing a system with a high SEER rating and following best practices for energy conservation, you can minimize your operating costs and enjoy a comfortable home or office all year round.
