7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is an excellent way to solve comfort issues in your home. These systems don’t require ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can have problems occasionally. Here are seven of the most common 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 could be a problem with the condensate drain or drain line. It’s expected for a drain line to be clogged with mold, force water to back up and leak. Call E.B. Air, LLC at 979-335-4262 for help and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re on. But there are a few instances where they may create sounds.

  • Popping or clicking: This can be because 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 keep itself from freezing over.

You shouldn’t be worried if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is up, including insufficient refrigerant, a bad circuit board or defective sensors. Your E.B. Air, LLC HVAC tech will be able to locate and resolve the issue 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 could be to blame. Like we mentioned prior to this, icy coils can be the result of not enough refrigerant, a bad circuit board or defective sensors. Contact us at 979-335-4262 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 needs refrigerant to move heat and keep your home comfortable. These leaks must be repaired by a licensed HVAC technician, so contact us at 979-335-4262 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job 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 very well is if it’s too large. A system that’s too big will cool down a room too rapidly without having time to dehumidify it. Mini-split size is planned 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 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 professional like E.B. Air, LLC examine 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 probably dealing with a refrigerant leak. Another certain hint that you don’t have ample refrigerant is a low concentration of cool air. Contact us at 979-335-4262 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Nevertheless, contact us at 979-335-4262 for assistance.

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 turn on. In the majority of experiences, putting in fresh batteries will fix the problem. If you’re still running into trouble, call us at 979-335-4262.
