How to Troubleshoot a Ductless Mini-Split System

A ductless mini-split system boasts high efficiency and effective cooling, especially when it receives regular maintenance and tune-ups. If you notice something wrong with your ductless mini-split, make sure to call your technician for inspection and repairs.

To give you an idea of how experts troubleshoot a ductless mini-split system, here’s an overview from trusted HVAC specialist Thomas J. Fannon & Sons.

Dirty Filters

Clogged air filters impede the airflow in your cooling system. Make sure to clean or replace your air filters regularly so that you can prevent dirt buildup. The schedule of air filter replacement depends on certain factors, like the type of air filter you have, your environment, the presence of pets, etc. You can consult your trusted air conditioning specialist for instructions and a timetable on which to carry out this task.

Clogged Drain Lines

You should check your HVAC system’s drain line regularly to ensure there is no buildup that could back up the line. If there is a buildup in your drain line, this could force the system to shut down due to water damage. You might be able to clear the drain line by pouring a small amount of vinegar down the line. Do this a few times each year to break up and flush any buildup that may be starting to form. If your unit doesn’t seem to be draining at all or the indoor air handler is leaking, you should contact your HVAC technician right away.

Refrigerant Leaks

A ductless mini-split uses refrigerant to cool your home. This refrigerant is circulated between indoor and outdoor units through cables. If you notice a leak in these cables, it could be due to the cables becoming worn or damaged by pests. Call a professional to confirm the source of the leak and replace or repair any leaky lines in your HVAC system.
