These systems are known for their durability and energy efficiency, making them a popular choice for many homeowners. With proper installation, regular maintenance, and occasional repairs, ductless systems can provide reliable climate control for many years.
Ductless systems are composed of an outdoor compressor/condenser unit and one or more indoor air-handling units. The compressor unit generally has a longer lifespan of 15-20 years, while the indoor units may need to be replaced after 10-15 years of use. Regular filter changes, coil cleanings, and refrigerant checks are important to maximize the system's longevity.
