Cleaning a mini split is very easy. Light cleaning and dusting periodically with a dry cloth or vacuum is recommended. Every 4-6 weeks, inspect, and clean your indoor unit’s air filter. Make sure your system is turned off before opening the cabinet. Inspect your outdoor unit periodically and remove any leaves, debris, and keep nearby shrubs trimmed away from the unit.
Mini Split cleaning can be done by either the homeowner or an experienced HVAC technician. Always follow the manufactures instructions on how to best clean your mini split.
