7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a fantastic approach to solve comfort problems in your home. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues occasionally. Here are seven of the most common mini-split issues and how you can solve 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 WM J Kraus & Son at 319-229-2318 for assistance and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re operating. But there are two situations where they might create sounds.

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

You shouldn’t be alarmed if you hear these noises since they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a sign that something is off, such as not enough refrigerant, a bad circuit board or defective sensors. Your WM J Kraus & Son HVAC professional will be able to locate and solve the issue rapidly.

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

If your mini-split is not heating or blowing hot air, ice on the coils may be to blame. Like we mentioned prior to this, frozen coils might be the effect of insufficient refrigerant, a faulty circuit board or broken sensors. Call us at 319-229-2318 for support.

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

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC needs refrigerant to move heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC technician, so call us at 319-229-2318 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job 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 very well is if it’s too large. A system that’s too large will cool down a room too rapidly without having a moment to dehumidify it. Mini-split size is based 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 likely have a mold issue. Have a pro like WM J Kraus & Son inspect and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another surefire clue that you don’t have ample refrigerant is a lack of cool air. Contact us at 319-229-2318 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Nevertheless, reach us at 319-229-2318 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t switch on. In the majority of instances, putting in new batteries will solve the issue. If you’re still experiencing trouble, reach us at 319-229-2318.
