While the maintenance required for your ductless AC system will vary depending on your manufacturer and model, there are several things that should be handled regardless of the system you choose to cool your home, including:
Regular dust and debris removal: This will prevent damage to the internal components of your unit to make sure the exterior remains clean. Routinely wiping your unit down with a cloth or gentle cleanser will help dust and dirt from making its way inside.
Cleaning the filter: You will need to either vacuum or clean your unit’s air filter with warm water and a mild detergent every month. This keeps your system operating at maximum efficiency, prolonging the service life of your ductless system.
Make sure the airflow is unrestricted: While ductless mini-splits require less space than a traditional cooling system, you should still ensure a clearance of at least 4 feet to maintain an unrestricted flow.
Inspect and clean the outdoor condensing unit. You should inspect the refrigerant lines and insulation wraps for general wear or leaks on your outdoor unit. If you’re unsure how to do this, you can always enlist the help of your local professionals!
