How to do it — step by step
Schedule a licensed HVAC technician to service your mini-split each spring before the cooling season begins. The tech will deep-clean the indoor head(s) with a pressurized wash, clean the outdoor condenser coil, check refrigerant charge and look for leaks, verify electrical connections, test the condensate drain for blockages, and calibrate temperature sensors. Request a system performance report. Ductless systems are highly efficient but refrigerant leaks go unnoticed without testing — a system operating with low refrigerant uses 10–20% more electricity and eventually damages the compressor. Annual service extends compressor life from 10 to 15+ years.
