5 Common Ductless Mini-Split Air Conditioner Repair Faults

Ductless mini-split air conditioners have recently become more popular in American homes because of their ease of installation and maintenance. But that doesn't mean they don't occasionally become faulty. Although the mini-splits are some of the most energy-efficient air conditioners on the market, there are several common problems they can develop. This guide discusses a few common mini-split faults that require the attention of an AC repair service:

1. Poor Installation

One of the most common faults with ductless mini-split air conditioners is that they may have been poorly installed in the first place. Are you not getting cold enough air? If your HVAC installer didn't seal up your system well or otherwise missed crucial steps during installation, you might have a larger problem on your hands than just a few repairs. You can only solve this problem by having an AC service inspect the installation and rectify it. 

2. The AC is Dripping Water 

Is the mini-split unit dripping water? This could be a sign of clogs in the condensate drain, whose function is to remove excess moisture from inside your air conditioner. When this drain clogs, water backs up and starts dripping to the ground. The AC technician will clear the drain and wash it with antiseptic to prevent mold growth.

3. The AC is Making Unusual Noises

You will hear clicking or popping noises as the AC's housing expands or contracts, which can be a sign that some components are not fastened properly.

The AC will make crackling, swooshing, or gurgling when it has a cycling problem. It keeps alternating between defrosting and freezing again. Call an AC repair service to look at the power system. 

4. The AC is Giving Off a Nasty Smell

The ductless mini-split AC has an internal air filter. The internal air filter gets clogged over time, and if you don't replace it every few months, it can give off a nasty fishy smell due to the microorganisms growing in it. 

A musty smell should alarm you because it signals mold growth. Mold presents a health hazard because the toxic spores can easily spread in the air pushed from the AC. Call an AC technician immediately because you may have a refrigerant leak when you smell vinegar. 

5. The AC Does Not Power On

When the AC does not power on, the obvious problem is a lack of power. Call a technician to test the AC's power system. Usually, power problems are straightforward and quick to fix when the technician has the correct tools.

It is almost unimaginable to be in a home without air conditioning today, so you should always be on the lookout for AC problems. Call an AC repair service to diagnose your mini-split ductless AC problems.
