7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort difficulties in your house. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have troubles 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 become clogged with mold, force water to back up and spill. Contact Jack's Heating, Cooling, Stoves & Fireplaces at 308-321-4703 for assistance and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re on. But there are two instances where they may make 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 turns on defrost mode to stop itself from freezing up.

You shouldn’t be alarmed if you hear these noises since they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is up, including not enough refrigerant, a flawed circuit board or broken sensors. Your Jack's Heating, Cooling, Stoves & Fireplaces HVAC tech will be able to locate and resolve the situation rapidly.

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 the problem. Like we mentioned before, frozen coils could be the consequence of low refrigerant, a failing circuit board or defective sensors. Call us at 308-321-4703 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 house comfortable. These leaks must be repaired by a licensed HVAC tech, so reach us at 308-321-4703 for help.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s oversized. A system that’s oversized will cool down a room too fast without having time 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 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 might have a mold issue. Have a pro like Jack's Heating, Cooling, Stoves & Fireplaces inspect and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another certain clue that you don’t have enough refrigerant is a lack of cold air. Reach us at 308-321-4703 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Nevertheless, reach us at 308-321-4703 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t switch on. In many experiences, putting in new batteries will fix the situation. If you’re still experiencing trouble, reach us at 308-321-4703.
