7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort issues in your residence. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can have issues sometimes. Here are seven of the most common mini-split problems 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 may be a situation with the condensate drain or drain line. It’s common for a drain line to get clogged with mold, force water to back up and spill. Call Breathe Healthier Air at 772-600-7151 for support and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re on. But there are a couple of times 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 freezing over.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is up, like insufficient refrigerant, a bad circuit board or defective sensors. Your Breathe Healthier Air HVAC technician will be able to find 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, frozen coils could be to blame. Like we discussed before, iced-over coils could be the consequence of low refrigerant, a failing circuit board or broken sensors. Contact us at 772-600-7151 for help.

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 transfer heat and keep your home cool. These leaks must be repaired by a licensed HVAC technician, so contact us at 772-600-7151 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 can be interrupted by blockages 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 oversized will cool down an area too fast without having a chance 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 grab your attention that something is wrong. Here are five of the most typical 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 Breathe Healthier Air check 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 enough refrigerant is a weak flow of cool air. Reach us at 772-600-7151 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Nevertheless, call us at 772-600-7151 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t switch on. In most instances, replacing the batteries will fix the trouble. If you’re still running into trouble, contact us at 772-600-7151.
