Ductless mini-splits have quickly become a popular choice for those looking for an efficient and cost-effective way to heat and cool their homes. However, like any type of HVAC system, ductless mini-splits can experience various problems.
In this guide, we’ll take a look at four of the most common problems with ductless mini-splits and how to fix them.
-
Problem: The Outdoor Unit is Making Strange Noises
If you notice that the outdoor unit of your ductless mini-split is making strange noises, it could be due to several different issues. The most likely culprit is a loose component. If a screw or bolt has come loose, it can cause the outdoor unit to vibrate and make noise. Simply tightening the loose component should fix the problem.

Problem: The Indoor Unit is Leaking Water
If you notice water leaking from the indoor unit of your ductless mini-split, there are a few possible causes. The most common cause is simply condensation. When the air conditioner is running, it can cause condensation to form on the coils. This condensation will eventually drip down into a drain pan and out of the unit. If you notice water leaking from the unit, simply empty the drain pan and wipe away any water that has accumulated.

Problem: The Air Conditioner isn’t Cooling the Room Evenly
If you find that the air conditioner isn’t cooling the room evenly, there are a few possible causes. First, check to make sure that all of the vents are open. If some of the vents are closed, it can cause the air conditioner to work harder and not cool the room evenly.

Problem: System Won’t Power On
If your ductless mini-split won’t turn on, the first thing you should check is the power. Make sure the power switch is in the ON position and that the circuit breaker has not been tripped. If the power is on and the circuit breaker is not tripped, the next step is to check the thermostat. In some cases, the thermostat may be set to the wrong mode, or the set point may be too high or too low.
If the thermostat is set correctly and the unit still won’t turn on, the next step is to check the outdoor unit. Make sure the outdoor unit is properly plugged in and that the disconnect switch is in the ON position. If the outdoor unit is plugged in and the disconnect switch is in the ON position, the next step is to check the compressor. The compressor is located behind the control panel on the outdoor unit. If the compressor is defective, it will need to be replaced.
Conclusion
There are a few common problems that can occur with ductless mini-splits. Fortunately, they can all be fixed relatively easily. If your unit is not cooling or heating properly, it is likely due to an issue with the air filter, compressor, or refrigerant levels. If you are experiencing strange noises coming from the unit, it is likely due to an issue with the outdoor fan. And finally, if your unit is leaking water, it is likely due to a clogged drain line. By following the troubleshooting tips in this guide, you should be able to easily fix any of these common problems.
