The answer to 'how to maintain mini split' is to perform regular cleaning, inspections, and maintenance on your mini split air conditioning system. This includes cleaning the air filters, outdoor unit, and indoor unit, as well as checking refrigerant levels and clearing any blockages or obstructions. Proper maintenance can help extend the life of your mini split system and ensure it continues to operate efficiently.
It's recommended to clean the air filters every 1-3 months, depending on usage and environmental conditions. The outdoor unit should be cleared of debris and the coils cleaned annually. The indoor unit should also be wiped down regularly to remove dust and grime buildup. Refrigerant levels should be checked periodically by a professional HVAC technician, who can also perform any necessary repairs or recharging.
