7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort problems in your home. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can run into problems from time to time. Here are seven of the most common 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 common for a drain line to become clogged with mold, force water to back up and drip. Contact J.L. Brady Company LLC at 309-517-7511 for support and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re operating. But there are a few times where they could create sounds.

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

You shouldn’t be troubled if you hear these noises as they’re normal. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is off, including low refrigerant, a flawed circuit board or broken sensors. Your J.L. Brady Company LLC HVAC professional will be able to find and solve the situation quickly.

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

If your mini-split is not heating or blowing hot air, frozen coils may be the issue. Like we mentioned previously, frozen coils could be the result of not enough refrigerant, a faulty circuit board or defective sensors. Call us at 309-517-7511 for help.

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 uses refrigerant to move heat and keep your residence cool. These leaks must be repaired by a licensed HVAC professional, so reach us at 309-517-7511 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s oversized. A system that’s too big will cool down an area too rapidly without having a chance 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 get your attention 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 J.L. Brady Company LLC check and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably experiencing a refrigerant leak. Another surefire clue that you don’t have ample refrigerant is a lack of cold air. Contact us at 309-517-7511 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Nevertheless, contact us at 309-517-7511 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 out of juice, your mini-split won’t run. In the majority of experiences, putting in fresh batteries will resolve the issue. If you’re still running into trouble, reach us at 309-517-7511.
