7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort issues in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can run into troubles from time to time. Here are seven of the most common mini-split troubles and how you can repair them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there could be a problem with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and leak. Reach Osceola Air, LLC at 407-477-6319 for assistance and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re running. But there are a couple of times where they could create sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can take place if your mini-split switches into defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises as they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is off, like low refrigerant, a faulty circuit board or defective sensors. Your Osceola Air, LLC HVAC technician will be able to pinpoint and resolve the situation fast.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, icy coils might be to blame. Like we mentioned previously, iced-over coils might be the effect of low refrigerant, a bad circuit board or defective sensors. Contact us at 407-477-6319 for support.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC uses refrigerant to shift heat and keep your residence cool. These leaks must be repaired by a licensed HVAC tech, so reach us at 407-477-6319 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too big. A system that’s too big will cool down an area too quickly without having a moment to dehumidify it. Mini-split size is planned on square footage and BTUs.

6. Mini-Split Smells

If your ductless mini-split smells, it’s trying to tell you that something is wrong. Here are five of the most common smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a specialist like Osceola Air, LLC inspect and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another certain sign that you don’t have enough refrigerant is a weak flow of cool air. Contact us at 407-477-6319 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Nevertheless, contact us at 407-477-6319 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t switch on. In many instances, replacing the batteries will solve the issue. If you’re still having trouble, contact us at 407-477-6319.
