How To Fix Common Problems with Ductless Mini Splits

A well-maintained mini split usually doesn’t succumb to many issues, but when and if it does, it’s often one of the problems we’ll discuss today.

The good news is that all these issues are incredibly common and thus easily diagnosed and repaired by your mini split technicians and their team.

Let’s take a look!

Bad Wiring

If your mini split remote works only sporadically even when you’re aiming it right at the unit, this comes down to more than a low-quality signal. The mini split and remote can’t communicate well, and that’s a wiring issue.

You might want to bring out your mini split team to double-check that all the wiring was connected properly during installation. If not, there is no better time than the present to tighten everything up!

The Mini Split Won’t Power On

Your mini split system was just fine yesterday, but today, it won’t turn on no matter what you do.

At the very least, it could be a power supply issue. If so, that will affect other appliances and electronics in your home too.

If not that simple fix, then perhaps you have the settings of the mini split wrong? If you’re still new to the world of mini splits, that’s very possible.

The unit could have also overheated, or the thermostat is malfunctioning so the mini split doesn’t need to turn on because of the incorrect temperature reading.

The Coils Have Frozen

An accumulation of ice on your mini split coils can be scary stuff, especially when it happens in the dead of summer!

The reason for the ice can come down to something as simple as dirty filters. Once you replace the filters, the coils can thaw.

Dirty coils can also freeze. A lack of coolant can contribute to this issue as well, and that will require your mini split technician to top off the levels.

The Mini Split Smells Bad

Does the air that comes out of your mini split have a concerted aroma, and it’s not a pleasant one, either? Perhaps the air smells sour, musty, or even earthy or moldy.

The drain line and/or condensate line could likely use a cleaning, which is a job for your mini split technician.

The Mini Split Won’t Dehumidify

In the summer, when excess moisture levels can accumulate in the air, you’ll appreciate the dehumidifying capabilities of your ductless mini split. Well, until they stop working, that is.

If your mini split is bigger than what your home needs, it might not be able to properly dehumidify. The reason? The room had gotten so cold that the mini split didn’t even get the chance to launch into dehumidifying mode.

A clogged condensate drain line can also prevent dehumidification, as the moisture from the process now has nowhere to go.

The Mini Split Is Noisy

Depending on what kind of sound you’re hearing, you could have different issues with your mini split.

For example, a gurgling or crackling sound is attributed to frozen components in the mini split while clicking or popping noises might be as simple as plastic parts contracting and expanding.
