Ductless mini-split malfunctions often happen at the worst time. Signs of poor performance—such as a room not cooling, water leaking, an error code, or continuous operation—negatively impact your comfort and raise utility costs.
At Air Logic, we provide Ductless Mini Split Repair in Columbia, SC with the quick response and clear answers you deserve—backed by 30+ years of local experience, certified technicians, and 24/7 emergency service as part of our complete HVAC Services.
If your ductless mini-split isn’t cooling or heating properly, start by confirming the mode (cool/heat), setting the temperature a few degrees past room temperature, checking the air filter, and making sure nothing is blocking airflow. If the unit still won’t perform—or you see leaks, ice, burning smells, loud noise, or repeated error codes—schedule professional service to prevent further damage and restore efficient operation.
Columbia’s long cooling season, high humidity, and heavy system run-time can expose small issues quickly—especially in ductless systems where clean airflow, proper drainage, and correct refrigerant charge are essential for stable comfort. When something is off, ductless equipment may still “run,” but performance drops fast (weak airflow, uneven temps, higher bills, or moisture problems).
That’s why our approach focuses on precision diagnostics and solutions that hold up—not quick fixes that repeat. Our support resources highlight the kind of testing we use to find root causes (like airflow testing and infrared imaging) so repairs actually last.
If you notice any of the following, it’s time to call:
Our team works on all major brands and provides honest, transparent recommendations—so you know what’s happening and why.
A ductless mini-split can “run” without truly cooling for several reasons. Some of the most common include:
Restricted airflow is a top culprit. When airflow drops, the system can’t transfer heat properly, leading to weak performance (and sometimes icing).
If the system isn’t reading room temperature correctly, it may not ramp up the way it should.
Low refrigerant (often tied to a leak) can cause poor cooling and coil icing. This needs professional diagnosis and proper repair—not just “topping off.”
Ductless systems rely on stable electrical components and communication between indoor and outdoor units. When that signal breaks down, comfort does too.
When we diagnose a cooling issue, we look beyond the symptom and verify airflow, drainage, and operating conditions so the repair is complete—not partial.
Seeing water drip from a wall-mounted unit is stressful—and it should be addressed quickly to prevent damage and mold risk. In many cases, the cause is related to condensate drainage, such as:
Because mini-splits remove moisture during cooling, the system must drain correctly. If the problem persists, professional service is recommended to avoid worsening damage.
Many ductless systems are heat pumps, so they provide both heating and cooling. If your unit struggles in heating mode, you might notice:
The cause could be airflow restriction, control/sensor issues, refrigerant charge, or other heat-pump-specific concerns. Our technicians handle ductless heat pump troubleshooting with the same diagnostics-first approach we use across our heating services.
Ductless mini-splits are smart systems—helpful when operating correctly, but sensitive when something is off. Error codes can point to:
Even if resetting the unit restores operation temporarily, recurring codes usually signal an underlying problem. We treat these calls as root-cause investigations, so you’re not stuck in a cycle of resets.
A quality repair isn’t just swapping parts—it’s verifying the system can run efficiently after the fix. Our visits are designed to provide dependable comfort and long-lasting performance, consistent with how we describe our service standards across Columbia and the Midlands.
Depending on the issue, service may include:
Mini-splits are efficient—but they’re not maintenance-free. Most manufacturers and HVAC educators recommend at least annual professional service to keep performance steady.
A solid upkeep routine helps:
If you’ve noticed more dust, more humidity, or allergy flare-ups, it can also be worth pairing maintenance with an indoor air quality strategy—especially in Columbia’s humidity and pollen-heavy seasons.
