The answer to 'lifespan of mini split' is that a well-maintained mini split air conditioner or heat pump system can typically last 10-15 years. These systems are designed for long-term use, but their lifespan depends on factors like frequency of use, maintenance, and quality of installation.
Mini split systems are generally more durable than window units or central HVAC systems. The outdoor compressor unit and indoor air handlers are built to withstand the elements and operate efficiently for many years. Regular professional maintenance, such as cleaning coils, checking refrigerant levels, and replacing air filters, can help maximize the lifespan of a mini split system.
