7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort troubles in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can experience troubles sometimes. Here are seven of the most frequent mini-split issues and how you can resolve them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there might be a problem with the condensate drain or drain line. It’s typical for a drain line to get clogged with mold, force water to back up and leak. Contact AC Sales at (337) 234-2345 for assistance and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re running. But there are a few times where they might make 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 take place if your mini-split switches into defrost mode to prevent itself from freezing up.

You shouldn’t be alarmed if you hear these noises as they’re typical. However, if your mini-split keeps going into defrost mode, it’s a clue that something is wrong, like low refrigerant, a faulty circuit board or broken sensors. Your AC Sales HVAC technician will be able to find and correct the problem 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 talked about before, iced-over coils might be the consequence of not enough refrigerant, a faulty circuit board or defective sensors. Contact us at (337) 234-2345 for assistance.

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 shift heat and keep your house cold. These leaks must be fixed by a licensed HVAC professional, so reach us at (337) 234-2345 for support.

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 properlyis if it’s oversized. A system that’s oversized will cool down a room too fast without having a chance 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 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 AC Sales check 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 likely encountering a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a lack of cool air. Contact us at (337) 234-2345 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Regardless, call us at (337) 234-2345 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 dead, your mini-split won’t run. In most instances, putting in fresh batteries will fix the trouble. If you’re still having trouble, reach us at (337) 234-2345.
