Ductless mini-split service for targeted heating and cooling.

Ductless mini-splits are useful when a space needs targeted comfort without adding ductwork. Randolph Mechanical services existing systems and provides consultation for new ductless installations.

Ductless mini-splits are useful for additions, finished basements, garages, apartments, offices, and rooms where central ductwork does not deliver enough comfort. They also need careful service because each zone has its own indoor head, controls, drain, sensors, and refrigerant connections.

Randolph Mechanical troubleshoots ductless systems that are leaking, icing, not responding to the remote, failing to heat or cool, or producing uneven comfort between zones.
