Ductless systems fail differently from ducted ones. A blinking light and a code, a head that runs but barely cools, water marking the wall below the indoor unit, or an outdoor unit that never starts. We diagnose and repair mini split systems in Elkins and across Northwest Arkansas, including systems other companies installed.
The symptom narrows it down long before anything is opened up.
The indoor head is reporting a fault. The code tells us where to start, so have it when you call.
Airflow, a dirty indoor coil or blower wheel, or a refrigerant problem. All three feel the same from the sofa.
Condensate that is not draining where it should, which is a plumbing path problem more often than an equipment one.
Power, controls, communication between the units, or a failed component in the outdoor unit itself.
Airflow or refrigerant, and the ice is a symptom of the cause rather than the cause.
On a multi zone system, a single head that stops behaving points somewhere very different from the whole system going down.
Ductless systems tend to fail in a handful of places. Airflow at the indoor head, the state of the filters and the indoor coil, the condensate path, and on the system side the refrigerant charge, the electrical components and whether the indoor and outdoor units are talking to each other. An error code, where there is one, usually points at which of those to look at first.
We diagnose before we replace parts. That means checking refrigerant pressures, electrical components and airflow, then telling you what failed and what the repair means for the rest of the system. You get the answer before the work starts.
A line set that was never vacuumed properly, a head mounted where it cannot move air, a condensate line run uphill, an undersized system that has been fighting the room since the day it went in. These are not failures in the equipment, and replacing parts will not settle them.
If that is what we find, we will tell you plainly, including when the honest answer is that the system was the wrong size for the space. What a correct install involves is on the ductless mini split installation page.
For ducted systems, central air and heat pumps, start with AC repair instead.
Short, direct answers to the questions we hear most.
