7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort problems in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can have issues occasionally. Here are seven of the most typical mini-split troubles and how you can solve 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 become clogged with mold, force water to back up and drip. Contact Pliescott HVAC Services LLC at 410-228-4822 for assistance and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re running. But there are a couple of times 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 goes into defrost mode to keep itself from icing up.

You shouldn’t be worried if you hear these noises since 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 defective sensors. Your Pliescott HVAC Services LLC HVAC pro will be able to find and correct the issue 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 the issue. Like we mentioned before, iced-over coils could be the consequence of low refrigerant, a failing circuit board or malfunctioning sensors. Reach us at 410-228-4822 for help.

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 residence cool. These leaks must be fixed by a licensed HVAC professional, so reach us at 410-228-4822 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be interrupted by clogs 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 large will cool down a space too rapidly without having a moment 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 common 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 professional like Pliescott HVAC Services LLC examine and rinse the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely dealing with a refrigerant leak. Another surefire hint that you don’t have sufficient refrigerant is a low concentration of chilled air. Call us at 410-228-4822 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Regardless, reach us at 410-228-4822 for support.

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 many situations, replacing the batteries will resolve the situation. If you’re still running into trouble, contact us at 410-228-4822.
