7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort troubles in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles from time to time. Here are seven of the most frequent 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 an issue with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, force water to back up and drip. Reach Mayeuxs AC & Heating at (985) 764-2426 for assistance and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re operating. But there are two instances 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 take place if your mini-split turns on defrost mode to stop itself from freezing over.

You shouldn’t be alarmed if you hear these noises because they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is up, like insufficient refrigerant, a bad circuit board or malfunctioning sensors. Your Mayeuxs AC & Heating HVAC pro will be able to locate and solve the problem rapidly.

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

If your mini-split is not heating or blowing hot air, icy coils might be the problem. Like we mentioned prior to this, icy coils may be the consequence of insufficient refrigerant, a failing circuit board or defective sensors. Reach us at (985) 764-2426 for assistance.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC uses refrigerant to move heat and keep your home cold. These leaks must be resolved by a licensed HVAC tech, so contact us at (985) 764-2426 for help.

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 halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too big. A system that’s too large 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 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 might have a mold issue. Have a specialist like Mayeuxs AC & Heating inspect 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 possibly encountering a refrigerant leak. Another certain clue that you don’t have sufficient refrigerant is a weak flow of chilled air. Call us at (985) 764-2426 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Either way, reach us at (985) 764-2426 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t switch on. In most experiences, putting in fresh batteries will resolve the problem. If you’re still experiencing trouble, contact us at (985) 764-2426.
