Answer:
Cleaning a mini-split is essential for maintaining its efficiency and longevity. In our experience, the process involves cleaning both the indoor and outdoor units. For the indoor unit, you’ll need to remove and wash the air filters, wipe down the unit’s exterior, and clean the evaporator coil with a gentle spray or specialized coil cleaner. For the outdoor unit, it’s important to clear any debris around it and carefully rinse the condenser coil. Our customers often tell us they feel intimidated at first, but we always remind them that regular cleaning can prevent costly repairs and ensure optimal performance. Of course, if you’re unsure, a professional HVAC technician can handle it for you.

Regular maintenance of your mini-split isn’t just about performance—it’s about air quality too. Dust, pollen, and other contaminants can build up in the system and circulate through your home if not cleaned regularly. In our professional experience, cleaning the filters every two weeks during heavy use is ideal, but at a minimum, you should clean them monthly.
Another critical aspect is cleaning the drain line and checking for clogs, as a blocked drain can cause water to back up into the unit. For those who want to go a step further, using a vacuum or compressed air to clean hard-to-reach areas is a good practice. Customers have also asked us about deep cleaning, and we always recommend scheduling this annually with a professional to ensure every component, including the blower and fan blades, is spotless.
