When the Mini Split Stops, the Room Stops With It

Your mini split blows warm air, or ice creeps along the line set, or water tracks down the wall under the head. Each of those has a cause, and we name it before we touch a part.

We work on ductless equipment every week, so a wall-mounted head is familiar work for us. Our technicians carry the gauges, meters and manufacturer literature this equipment needs, and we happily service ductless systems we did not install.

We diagnose first and quote second, so you hear what failed and what it costs before anything is opened up. A repair that makes sense is the repair we do, and our central ac installation page covers the day a replacement serves you better.

What a Mini Split Repair Covers

Most of the calls we take on ductless systems come down to one of six problems, all of which we have repaired many times.

The room is warm even though the mini split is running.

Low refrigerant, a failed capacitor or a tired fan motor will all do this. We check the charge, test the electricals and look for the signs of a refrigerant leak.

You can see ice on the coil or on the pipes outside.

Ice means the system cannot move heat, usually because of a dirty filter or a low charge. We thaw it, clean the coil and correct the charge.

Water is running down the wall underneath the head.

This one looks alarming and is usually the least expensive to put right. We clear the condensate drain, reset its slope and flush the pan.

A code is flashing and the system has shut itself down.

The indoor head and the outdoor unit talk constantly, so a sensor, a board or the wiring between them has stopped reporting. We read the code and replace the part that failed.

One room has gone cold while the other heads keep working.

On a multi-zone mini split that points to a stuck valve, a failed sensor or a board on the one head. We test each zone and repair only the one that failed.

It cools in summer but the heating has stopped.

A ductless heat pump that quits in the shoulder season is usually stuck in defrost or short of refrigerant. We test the reversing valve, the defrost control and the charge.

Is Your Ductless System Worth Repairing?

Some faults are worth fixing on a ten-year-old system and some are not. We tell you which one you are looking at before you spend anything.

What failed System age What we usually recommend
Capacitor or contactor Any age We repair it, and nothing else is disturbed.
Indoor blower motor Under 12 years We repair it, because the system has years left.
Control board Under 10 years We repair it once we confirm the board is the fault.
Leak at a flare joint Any age We seal the joint, recharge and retest the system.
Compressor Under 8 years We repair it, and the warranty may still apply.
Compressor Over 12 years We say plainly that a new ductless unit is better value.

The Homes These Systems Keep Comfortable

Century houses, converted attics, additions and finished basements are everywhere here, and most of them have no ductwork at all. When the mini split on the wall stops, you lose the use of the room, so we treat those calls as urgent.

We service ductless equipment whatever the brand and whoever installed it, including systems put in by a company that has since closed. If you run a multi-zone system, we isolate the head that failed and quote that one repair.

Homes with ductwork are a different conversation, and our heat pump installation page is the better starting point.
