7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort difficulties in your home. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues from time to time. Here are seven of the most typical mini-split problems 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 a problem with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, force water to back up and spill. Reach Appalachian Heating at 304-707-0600 for help and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re running. But there are a few times where they could create sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is operating.
  • 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 as they’re typical. However, if your mini-split keeps going into defrost mode, it’s a hint that something is up, including not enough refrigerant, a flawed circuit board or malfunctioning sensors. Your Appalachian Heating HVAC professional will be able to pinpoint and correct the problem fast.

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

If your mini-split is not heating or blowing hot air, icy coils could be the issue. Like we mentioned previously, icy coils could be the consequence of low refrigerant, a bad circuit board or broken sensors. Contact us at 304-707-0600 for help.

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 relies on refrigerant to shift heat and keep your residence cold. These leaks must be resolved by a licensed HVAC tech, so reach us at 304-707-0600 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this could 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 oversized. A system that’s too big will cool down a space 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 tell you 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 likely have a mold issue. Have a pro like Appalachian Heating inspect and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another surefire hint that you don’t have enough refrigerant is a lack of cool air. Reach us at 304-707-0600 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Either way, reach us at 304-707-0600 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are out of juice, your mini-split won’t switch on. In the majority of instances, putting in new batteries will fix the problem. If you’re still running into trouble, reach us at 304-707-0600.
