7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort troubles in your residence. These systems don’t require ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can experience issues occasionally. Here are seven of the most typical mini-split issues and how you can fix 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 get clogged with mold, force water to back up and drip. Contact YES R&M Inc. at 562-286-6624 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re running. But there are a couple of situations where they might create sounds.

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

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is off, such as not enough refrigerant, a flawed circuit board or defective sensors. Your YES R&M Inc. HVAC technician will be able to find and correct the situation fast.

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

If your mini-split is not heating or blowing hot air, ice on the coils might be to blame. Like we mentioned before, frozen coils might be the consequence of low refrigerant, a faulty circuit board or defective sensors. Reach us at 562-286-6624 for support.

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 relies on refrigerant to transfer heat and keep your residence cold. These leaks must be repaired by a licensed HVAC tech, so call us at 562-286-6624 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this may 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 large. A system that’s oversized will cool down an area too quickly 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 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 YES R&M Inc. check and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another certain sign that you don’t have ample refrigerant is a low concentration of cool air. Call us at 562-286-6624 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. Regardless, reach us at 562-286-6624 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are dead, your mini-split won’t run. In the majority of situations, putting in fresh batteries will resolve the problem. If you’re still having trouble, call us at 562-286-6624.
