7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort difficulties in your house. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles from time to time. Here are seven of the most frequent mini-split problems 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 could 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 leak. Contact Walter's-Eaton's Electric, Plumbing, Heating & AC at 715-318-6728 for help and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re operating. But there are two situations where they may make sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can take place if your mini-split turns on defrost mode to prevent itself from freezing up.

You shouldn’t be troubled if you hear these noises as they’re normal. However, if your mini-split keeps going into defrost mode, it’s a clue that something is up, including not enough refrigerant, a bad circuit board or malfunctioning sensors. Your Walter's-Eaton's Electric, Plumbing, Heating & AC HVAC tech will be able to locate and solve the issue fast.

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

If your mini-split is not heating or blowing hot air, icy coils may be the problem. Like we mentioned prior to this, icy coils might be the consequence of low refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 715-318-6728 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 relies on refrigerant to move heat and keep your home cool. These leaks must be resolved by a licensed HVAC technician, so reach us at 715-318-6728 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too big. A system that’s oversized will cool down a space too quickly 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 could have a mold issue. Have a pro like Walter's-Eaton's Electric, Plumbing, Heating & AC inspect and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another certain hint that you don’t have sufficient refrigerant is a lack of cool air. Reach us at 715-318-6728 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Nevertheless, call us at 715-318-6728 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 out of juice, your mini-split won’t turn on. In most situations, putting in new batteries will solve the problem. If you’re still experiencing trouble, reach us at 715-318-6728.
