7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a good approach to solve comfort issues in your house. These systems don’t need ductwork to deliver 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 common mini-split troubles 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 may be an issue with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and spill. Reach Fleming Heating & Air Conditioning Inc at 877-389-2465 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 on. But there are two times where they could make 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 turns on defrost mode to keep itself from freezing over.

You shouldn’t be troubled if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is up, like insufficient refrigerant, a flawed circuit board or malfunctioning sensors. Your Fleming Heating & Air Conditioning Inc HVAC pro will be able to pinpoint and solve 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 might be the issue. Like we mentioned previously, iced-over coils could be the effect of low refrigerant, a faulty circuit board or malfunctioning sensors. Contact us at 877-389-2465 for assistance.

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 needs refrigerant to transfer heat and keep your home cool. These leaks must be fixed by a licensed HVAC tech, so contact us at 877-389-2465 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be stopped by blockages 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 oversized will cool down a space too rapidly without having time 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 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 Fleming Heating & Air Conditioning Inc check and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a lack of chilled air. Call us at 877-389-2465 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Regardless, contact us at 877-389-2465 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 bad, your mini-split won’t run. In the majority of instances, putting in new batteries will solve the problem. If you’re still having trouble, contact us at 877-389-2465.
