The answer to 'when to service mini split' is that mini split air conditioning systems should be serviced at least once a year, typically in the spring before the cooling season begins. Regular maintenance is important to ensure the system is running efficiently and to identify any potential issues before they become major problems.
During a mini split service, a technician will clean the indoor and outdoor units, check refrigerant levels, test the electrical components, and inspect the system for any wear or damage. They may also clean or replace the air filters and ensure the condensate drain is working properly. Proper maintenance can extend the lifespan of your mini split system and help it operate at peak performance.
