7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort troubles in your home. These systems don’t need ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can have problems from time to time. Here are seven of the most typical 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 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. Reach Scott Temperature at 785-269-0465 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re operating. But there are two situations where they may produce 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 occur if your mini-split goes into defrost mode to prevent itself from freezing over.

You shouldn’t be worried if you hear these noises because they’re expected. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, like not enough refrigerant, a faulty circuit board or broken sensors. Your Scott Temperature HVAC technician will be able to find and correct the problem rapidly.

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 problem. Like we talked about prior to this, iced-over coils may be the consequence of insufficient refrigerant, a failing circuit board or malfunctioning sensors. Call us at 785-269-0465 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 shift heat and keep your home pleasant. These leaks must be fixed by a licensed HVAC technician, so call us at 785-269-0465 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 may 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 oversized. A system that’s too big will cool down a space too rapidly 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 get your attention 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 may have a mold issue. Have a professional like Scott Temperature check and rinse the condensate drain and drain line, if necessary.

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 low concentration of cold air. Call us at 785-269-0465 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Nevertheless, contact us at 785-269-0465 for support.

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 turn on. In the majority of instances, putting in fresh batteries will resolve the problem. If you’re still experiencing trouble, call us at 785-269-0465.
