4 Maintenance Requirements for Ductless Mini Split Systems
Keep your mini split system running efficiently for years with these four simple, essential upkeep steps.
Shop Mini Splits »Ductless mini split systems are one of the most popular heating and cooling solutions for homeowners who want energy efficiency, convenience, and zone-by-zone comfort. But like any HVAC equipment, a mini split system needs regular care to keep running at its best. Here are the four essential maintenance requirements every mini split owner should know.
The 4 Essentials
1. Clean or Replace Filters
Every 2 weeks with pets, monthly for normal use, or every 3 months for light use. Clogged filters hurt airflow, air quality, and efficiency.
2. Keep Both Units Clean
Wipe the indoor air handler and vents, and clear leaves/debris from the outdoor condenser with at least 2 feet of clearance.
3. Check Refrigerant Lines
Watch for ice on the coils, hissing sounds, or a drop in cooling power - all signs a mini split system may have a refrigerant leak.
4. Schedule Annual Service
A yearly professional tune-up catches issues early, extends lifespan, and keeps your mini split running like new.
