Do Ductless Mini Splits Need Servicing?

Ductless mini-splits, also known as ductless heat pumps or mini-split systems, are a type of heating and cooling system that do not require ductwork. They consist of an outdoor unit, which contains the compressor and condenser, and one or more indoor units, which contain the evaporator and air handling components.

Like any mechanical system, ductless mini-splits require regular servicing to ensure they are operating efficiently and effectively. Some of the key areas that need to be checked during mini-split maintenance include:

Refrigerant levels: The refrigerant in a ductless mini-split is responsible for transferring heat from one area to another. A technician will check the refrigerant levels to ensure they are at the correct level, and that there are no leaks.

Air filters: The air filters in the indoor units should be checked and cleaned or replaced as needed. 

Evaporator coils: The evaporator coils should be inspected for dirt and debris, and cleaned as needed. 

Condenser coils: The condenser coils should be inspected for dirt and debris, and cleaned as needed. 

Drain lines: The drain lines should be checked to ensure they are not clogged and that water is draining properly.

Electrical connections: The electrical connections should be checked for tightness and corrosion.

Compressor: The compressor should be checked for proper operation and any abnormal noise.

Airflow: The airflow through the system should be checked to ensure it is at the correct level and balanced between the indoor and outdoor units.

Mini-split maintenance can help prolong the life of a ductless mini-split and ensure that it is operating at peak efficiency. It is generally recommended to have the system serviced at least once a year, typically in the spring before the cooling season begins, or fall before the heating season.
