7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort troubles in your house. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can experience issues from time to time. Here are seven of the most typical mini-split issues 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 may be an issue 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 drip. Reach Kowalski Heating, Cooling & Plumbing at 724-370-0141 for support and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

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

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

You shouldn’t be troubled if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is wrong, like low refrigerant, a faulty circuit board or malfunctioning sensors. Your Kowalski Heating, Cooling & Plumbing HVAC technician 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 may be to blame. Like we mentioned previously, frozen coils may be the result of not enough refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 724-370-0141 for assistance.

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 house pleasant. These leaks must be fixed by a licensed HVAC professional, so contact us at 724-370-0141 for help.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be stopped by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s too big will cool down an area too rapidly without having a moment 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 grab 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 likely have a mold issue. Have a professional like Kowalski Heating, Cooling & Plumbing 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 possibly dealing with a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a low concentration of cool air. Reach us at 724-370-0141 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Nevertheless, call us at 724-370-0141 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 turn on. In the majority of situations, putting in new batteries will resolve the situation. If you’re still running into trouble, call us at 724-370-0141.
