Why is my ductless AC not blowing cool air? Is it a simple repair or one that requires a professional? Is it dangerous?

There’s nothing worse than finding that your ductless AC isn’t working during the hot summer months.

Fortunately, with the right approach, you can pinpoint the cause of your problem and take the necessary action.

The first thing you need to remember is this: there is no one-size-fits-all answer to the question of why your ductless AC isn’t performing at its peak.

Secondly, some issues are more difficult to repair than others. For this reason, you may need to consult with a repair professional.

What’s the Cause?

This is the million-dollar question. There’s nothing you can do until you know why your ductless AC isn’t cooling your home. After you figure that out, you can decide what to do next.

Here are some of the top culprits:

1. Thermostat Problems

The first thing you should check is your thermostat. For example, if you recently installed a smart thermostat, you may have done so incorrectly or put it on the wrong setting.

It could be as simple as turning the AC fan on, which results in the blower running non-stop. While that sounds like what you want, your system actually runs without cooling your home. So, you’ll feel air coming out of your blower, but it won’t be cool.

2. Clogged Air Filter

This is a simple fix, as long as the clog didn’t result in serious damage to your system.

Just the same as a conventional HVAC system, you must change its air filters regularly. If you don’t, airflow becomes restricted and you won’t feel the cold air you’re craving.

Get into the habit of inspecting your air filters every month. This will give you a better idea of how often you need to clean or replace them.

Tip: save yourself some money by regularly cleaning your air filters with dish soap and warm water.

3. Refrigerant Leak

Your ductless AC system can’t work without refrigerant. This is used to convert warm air to cold air.

Depending on the location and size, the leak may not stop your system from working entirely. However, it will affect performance and is likely to lead to a complete malfunction in the future.

If your AC isn’t cooling your home or you spot ice crystals on the outside refrigerant line, there’s a good chance this is the culprit.
