Mini-Split Repair

Mini-Split Repair in Somerville, Massachusetts

A ductless mini-split that’s stopped cooling, stopped heating, or started running nonstop usually has one of a small number of real causes.

Signs Your Mini-Split Needs Repair

Not Cooling or Not Heating

The unit runs but the air coming out isn’t the right temperature — often a refrigerant, filter, or sensor issue.

Running Constantly

A system that never cycles off is usually oversized for the space, low on refrigerant, or fighting a failing sensor.

Unusual Noise

Clicking, buzzing, or rattling from the indoor or outdoor unit is worth a look before it becomes a bigger repair.

Error Code on the Display

Tell your contractor the exact code when you call — it speeds up diagnosis considerably.

Water Leaking From the Indoor Unit

Usually a clogged condensate drain line — a common, generally inexpensive fix if caught early.

Common Causes

Low refrigerant charge, a dirty or clogged filter, a failing sensor or control board, a clogged condensate line, or — less commonly — an outdoor unit affected by ice buildup or debris. A real diagnosis identifies which one you’re actually dealing with rather than guessing.
