7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort difficulties in your residence. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have issues sometimes. Here are seven of the most frequent 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 might be an issue 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 spill. Reach Freed Heating & Air Conditioning at 309-323-9584 for support and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re operating. But there are a few instances where they could 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 take place if your mini-split goes into defrost mode to prevent itself from icing over.

You shouldn’t be worried if you hear these noises since they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is wrong, including low refrigerant, a flawed circuit board or defective sensors. Your Freed Heating & Air Conditioning HVAC pro will be able to locate and correct the issue rapidly.

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

If your mini-split is not heating or blowing hot air, frozen coils might be the issue. Like we talked about prior to this, icy coils can be the result of insufficient refrigerant, a bad circuit board or malfunctioning sensors. Call us at 309-323-9584 for support.

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 home pleasant. These leaks must be fixed by a licensed HVAC pro, so contact us at 309-323-9584 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be interrupted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s oversized. A system that’s too big will cool down a space too rapidly 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 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 could have a mold issue. Have a specialist like Freed Heating & Air Conditioning 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 likely dealing with a refrigerant leak. Another surefire clue that you don’t have enough refrigerant is a low concentration of cold air. Call us at 309-323-9584 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Either way, call us at 309-323-9584 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t switch on. In many situations, putting in fresh batteries will fix the situation. If you’re still experiencing trouble, reach us at 309-323-9584.
