Benefits of Ductless Split Maintenance

Ductless split systems require professional maintenance at the same frequency traditional HVAC systems do. For ductless split heating and cooling systems that utilize a heat pump, service is necessary twice per year – once for heating season and once for cooling season. If you use a ductless split system air conditioner, once per year maintenance is sufficient.

In addition to professional maintenance care, ductless split systems need frequent filter maintenance to maintain good airflow, which improves comfort and energy efficiency. Each indoor air handling unit of a ductless split system is equipped with its own air filter, which is typically reusable.

Reusable filters do need to be cleaned to remove contaminant buildup. How frequently this ductless split maintenance task is needed varies depending on the manufacturer’s recommendation and factors related to your home. On average, about every four to six weeks is the right interval.
