4 Signs You Need Mini Split Repairs

If you have a ductless mini split, you have to pay close attention to how it’s operating and watch for signs that something is wrong. Because mini split units are essentially smaller versions of whole-house air conditioners, things can go wrong quickly and need to be addressed right away.

If you need mini split service in Staten Island, NY, our team is here to help. In the meantime, you can keep reading to learn about four of the most common signs that your mini split unit is struggling and needs to be repaired.


Water should never leak out of your ductless mini split air conditioner. However, it’s still one of the more common problems for the units. The condensate drain line works just like it does for a larger whole house air conditioner. The difference is that the lines are much smaller in a ductless system. It’s easier for clogs to develop in the condensate drain line of a mini split unit if it’s not well cared for.

If you notice a water leak, give our team a call right away. Water can do damage to other components inside the mini split unit, and the problem won’t resolve itself without professional help. Once we clean out the drain line, we can make recommendations for how you can flush out the line once a month and keep it clear from clogs in the future. This is a great way to prevent leaks from happening again.

Ice Buildup

Just like a central air conditioner, your mini split unit has a set of coils that aid in cooling air for your home. If ice develops on these coils, it could also be a possible reason for a leak. When ice thaws, the water will drip out of the unit. But ice is a problem for more reasons than just that. 

Ice developing on your evaporator coils means that you have poor airflow or a refrigerant leak. Ice is not making your home cooler. Instead, it’s blocking airflow out of the system and putting strain on the entire unit. You want to get down to the source of the problem and fix it so that ice doesn’t continue to develop and thaw over and over again.

High Utility Bills

Ductless mini split air conditioners are well known for their energy efficiency. If you notice a sudden spike in energy use, there may be a problem with one or more of your individual units. Of course, there are other appliances in your home using energy, too. Your mini split unit may not be the problem at all, but it’s a good place to start looking since it’s one of the larger appliances in your home.

Bad Sounds or Smells

Another sign of ductless mini split problems is if you begin to notice bad smells or unusual sounds. Your mini split unit isn’t going to be completely silent as it operates, but it should be fairly quiet. Hearing anything out of the ordinary is concerning no matter how loud or quiet the sound is. 

You also want to consider that hearing unusual sounds just one time is a problem, even if you don’t continue hearing the sound over and over again. It’s always better to get your air conditioner checked out than to ignore a problem that could grow worse over time.
