7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a good approach to solve comfort difficulties in your house. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can have problems occasionally. Here are seven of the most typical mini-split troubles 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 may be an issue with the condensate drain or drain line. It’s expected for a drain line to be clogged with mold, force water to back up and drip. Reach Ilten's Incorporated at 319-208-3295 for help and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re running. But there are a few situations where they may create sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can occur if your mini-split turns on defrost mode to stop itself from icing over.

You shouldn’t be troubled if you hear these noises since they’re expected. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is up, such as insufficient refrigerant, a bad circuit board or defective sensors. Your Ilten's Incorporated HVAC professional will be able to find and solve the situation fast.

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 might be the issue. Like we mentioned previously, frozen coils might be the consequence of insufficient refrigerant, a failing circuit board or malfunctioning sensors. Call us at 319-208-3295 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 shift heat and keep your house cold. These leaks must be repaired by a licensed HVAC technician, so call us at 319-208-3295 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this may be stopped by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s too big will cool down a space too quickly without having time to dehumidify it. Mini-split size is calculated 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 usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you could have a mold issue. Have a specialist like Ilten's Incorporated examine and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another surefire sign that you don’t have enough refrigerant is a low concentration of cool air. Reach us at 319-208-3295 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, call us at 319-208-3295 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are out of juice, your mini-split won’t switch on. In most situations, putting in fresh batteries will fix the situation. If you’re still having trouble, call us at 319-208-3295.
