How Long Do Ductless Mini Splits Last?
The average lifespan of a ductless mini split system is 15-20 years, depending on the brand and model. Proper installation and maintenance can help extend the lifespan.
Installation
-
Installing your mini split by a licensed HVAC technician is key to ensuring maximum efficiency and longevity. Improper installation can reduce the lifespan by up to 5 years. Technicians are trained to correctly size the system for your space, properly seal and insulate the lines, position the air handler and condenser, and test to ensure optimal performance.
Maintenance
To keep your mini split running well for as long as possible, perform regular maintenance. This includes:
-
Inspecting and cleaning air filters once a month or as needed. Clogged, dirty filters reduce airflow and efficiency which can shorten the lifespan.
-
Vacuuming vents and air intakes regularly to remove built-up dust and debris.
-
Having a technician perform professional servicing once a year which includes inspecting components, testing refrigerant levels and system performance, cleaning coils and drainage pipes, and making any necessary repairs or replacements.
-
Replacing remote control batteries at least once every 3-6 months to ensure proper function.
-
Not obstructing vents or air intakes which prevents efficient airflow.
Repairs and Replacements
-
As the mini split ages, certain components like filters, fans, refrigerant, and coils may need to be repaired or replaced. It's best to have a technician inspect the unit if you notice any decrease in performance, strange noises, leaks, or error codes to minimize damage. Replacing major components like the compressor or condenser coils, can be expensive, so if numerous parts begin failing it may make more sense to replace the entire unit.

How Long Do Mitsubishi Mini Splits Last?
Mitsubishi mini splits are a reputable brand built to last 15-20 years with proper maintenance and care. However, the lifespan can vary depending on the unit's usage and climate.
-
Compressor: The compressor is the heart of a mini split and typically lasts 8-15 years. Heavy usage, extreme temperatures, and an undersized unit can reduce its lifespan.
-
Coils: The evaporator and condenser coils usually last 10-15 years. Dust buildup reduces efficiency and airflow, so regular cleaning is important. Corrosion from moisture or chemicals also decreases their longevity.
-
Refrigerant: The refrigerant recharge every 5-10 years. Lack of recharging causes the unit to work harder, reducing its lifespan.
-
Filters: Clogged or dirty filters reduce a mini split's lifespan by making it work harder. Replace filters every 1-3 months based on usage.
-
Ductwork: For ducted mini splits, leaky or insufficient ductwork lowers efficiency and lifespan. Properly sized, sealed ductwork should last 15-20 years.
-
Usage: Running a mini split for long periods at maximum output, especially in harsh weather conditions, causes faster wear and tear, decreasing its lifespan.
-
Maintenance: Annual maintenance by an HVAC technician helps detect and prevent issues, maximizing a mini split's longevity. Lack of maintenance often leads to premature failure.

How Long Do MRCOOL Mini Splits Last?
As an owner of an MRCOOL mini split system, you can expect many years of reliable comfort. Properly installed and maintained, MRCOOL mini splits provide an average lifespan of 15 to 20 years. However, several factors determine a unit’s longevity:
-
Installation: A mini-split installed by a certified HVAC technician according to the manufacturer’s guidelines will last longer than an improperly installed unit. Correct refrigerant charging, leak testing, and brazing are essential for maximum lifespan.
-
Usage: Mini splits used occasionally, such as in vacation homes or cabins, typically last longer than those running daily in a primary residence. More use means more wear and tear.
-
Maintenance: Following the recommended maintenance schedule for your MRCOOL mini split model is key. This includes filter changes, coil cleanings, and inspections by an HVAC pro. Neglecting maintenance shortens a unit’s life.

- Environmental conditions: Extreme heat, cold, humidity, or pollutants can stress a mini split and decrease its lifespan. MRCOOL units are built to handle a range of conditions, but severe or constant extremes will reduce longevity.
-
Repairs: Quickly addressing any issues with your MRCOOL mini split, such as strange noises, refrigerant leaks, or drops in performance, will help maximize its lifespan. Minor repairs and part replacements are often more affordable and eco-friendly than completely replacing a unit.
How Long Do Fujitsu Mini Splits Last?
The lifespan of a Fujitsu mini split system can vary depending on the specific model and how well it is maintained. On average, a Fujitsu mini-split should last between 15 to 20 years. With proper maintenance and care, some units may last longer. Several factors can impact the longevity of a Fujitsu mini-split.
Installation and Maintenance
How the unit is installed and maintained plays a significant role in determining how long it will last. It should be installed by a licensed HVAC technician according to the manufacturer's recommendations. The filters, coils, and drains should be properly cleaned and serviced regularly to allow for efficient operation. Failure to properly maintain the mini-split can reduce its lifespan by up to 50% due to excess strain on components.
Run Time
The amount of time a Fujitsu mini-split runs each day and throughout the year impacts its lifespan. Units that run nearly continuously for long periods each day, especially in extreme heat or cold, tend to have a shorter lifespan of 10 to 15 years. Units that run intermittently and in more temperate weather may last 20 years or more. The constant heating and cooling required for continuous operation puts extra wear and tear on the compressor and other parts.
Environmental Factors
Certain environmental factors like humidity levels, air pollution, and voltage fluctuations can also influence how long a Fujitsu mini-split will last. High humidity can lead to corrosion, while pollutants and unstable voltage may damage electronic components over time. Installing the unit in a sheltered area away from extreme environmental conditions is best for maximum longevity.
How Long Do Mini Splits Last
In conclusion, mini-split systems can provide efficient heating and cooling for 10-15 years or more when properly installed and maintained. While the units themselves are built to last, their lifespan greatly depends on factors like usage, environment, and care. With annual maintenance and filter changes, a mini-split system should continue operating well for over a decade in a residential setting.
