Installation and Maintenance Tips for Mini Split Air Conditioning

Mini Split Air Conditioning is one of the most popular ways of air conditioning in the modern era. They offer many advantages, such as saving space, easy installation, energy efficiency, and many more. However, like any air conditioning unit, it needs good installation and maintenance to achieve maximum effectiveness. In this blog post, we will discuss some essential tips for mini split Air Conditioning installation and maintenance that will help you get the best out of your system. 

Proper Installation 

Proper installation is vital for any Mini Split Air Conditioning unit. For this reason, we recommend seeking professional help rather than trying to install it yourself. Professionals are equipped with specialized tools and can guarantee the proper installation of the unit. Moreover, they can also ensure that the unit is level and securely mounted on the wall. Improper installation can not only result in inefficiency and increased energy bills, but it can also lead to damage and increased safety risks.

Duct Cleaning 

Ducts are an essential part of the Mini Split Air Conditioning unit that is responsible for distributing cool air evenly throughout the room. As such, it is vital to keep them clean to ensure that your system functions correctly. Dust, allergens, and contaminants can build up in your system over time and reduce its efficiency. Therefore, you will need to perform duct cleaning regularly. Depending on how often you use your Mini Split unit, we recommend cleaning the ducts at least once every six months.

Regular Maintenance 

Regular maintenance is essential for prolonging the lifespan of your Mini Split Air Conditioning unit. It’s recommended that you get it serviced at least once a year by a professional technician. Servicing includes an inspection of all parts, such as the coolant level, thermostat settings, refrigerant pressure, and mechanical components. Regular maintenance can help detect minor problems before they turn into major ones, and avoid expensive repairs.

Timely Filter Replacement 

Filters prevent allergens, dust, and debris from entering the Mini Split Air Conditioning unit. Therefore, it’s essential to replace them regularly to increase the efficiency of your unit. How often you need to replace your filters will depend on how often you use your unit. However, generally, it’s recommended to replace them once every two weeks during periods of high use and once every two months during low use.

Proper Placement 

Finally, proper placement of the Mini Split Air Conditioning unit is critical for its effectiveness and longevity. You should place the unit in a shady spot to avoid direct sunlight and prolong the lifespan of the unit. Moreover, you should avoid placing objects on top of the Mini Split Air Conditioning unit and ensure that the unit has proper ventilation, allowing for the free flow of air.

As summer is approaching, the mini-split air conditioning system has become an essential home appliance. While most people are familiar with the traditional window AC unit or central air, mini-split air conditioning is becoming popular for its energy-efficient solution, quiet operation, and ease of installation. However, like any other home appliances, mini-splits require maintenance and proper installation. In this blog, we will guide you through some easy installation and maintenance tips that can save you time and money in the long run.

Installation Tips:

Choose the location wisely: It would help if you chose where to install your mini-split wisely. A good location would be on an exterior wall near the unit’s outdoor condenser. It will make the installation process easier and make it easier for the refrigerant lines and electrical cables to be run directly to the outdoor unit.

Proper placement: Make sure that the unit is level and has a slight pitch towards the outdoor unit. And avoid installing the unit near direct sunlight or heat sources like a stove or oven. The temperature of the unit’s condenser should never exceed 120 degrees Fahrenheit, which can damage the unit.

Hire a professional installer: While most of the installation processes are DIY-friendly, it’s always best to hire an HVAC professional to ensure your mini-split unit is correctly installed. They can help you choose the right size, ensure the refrigerant lines are the correct length, and charge the system with the proper refrigerant.

Maintenance Tips:

Clean or replace the filter regularly: Dirty filters can restrict air flow, causing your mini-split to work harder and decreasing its lifespan. Clean or replace your filters every 3-4 months.

Check for leaks: Check the refrigerant lines for any leaks or damage and repair them as soon as possible. A refrigerant leak can decrease the efficiency of the unit, increasing your energy bill, and damage the compressor over time.

Clean the outdoor unit: Dirt, leaves, and other debris can clog the outdoor unit’s vents, decreasing system efficiency and causing your unit to work harder. Make sure to clean the unit’s exteriors regularly.

Schedule professional maintenance: It’s always best to have your mini-split serviced by a professional HVAC technician every 2-3 years to ensure optimum performance and detect any potential problems.


Mini Split Air Conditioning is a fantastic option for cooling your home or office. However, with great benefits come significant responsibilities. Proper installation, regular maintenance, timely filter replacement, duct cleaning and proper placement are essential for keeping your unit working at optimal levels. If you take good care of your Mini Split Air Conditioning unit, it will take good care of you. So, take the time to perform regular maintenance and follow the above tips, and you will be rewarded with a comfortable, energy-efficient, and long-lasting air conditioning system.


As you can see, proper installation and maintenance are the critical factors that determine your mini-split air conditioning’s longevity and efficiency. While most of the installation and maintenance tips can be done as DIY projects, hiring a professional technician to do them can give you peace of mind that your system is up to code and running optimally. By following these easy installation and maintenance tips, you can keep your mini-split air conditioning running smoothly and effortlessly.
