7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a fantastic way to solve comfort problems in your home. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have problems from time to time. Here are seven of the most frequent 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 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 leak. Call Watts Electric & A/C Inc at 601-736-7362 for assistance and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re on. 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 on.
  • Swooshing, crackling or gurgling: This can take place if your mini-split goes into defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises because they’re typical. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is off, like low refrigerant, a bad circuit board or defective sensors. Your Watts Electric & A/C Inc HVAC pro will be able to find and correct the situation fast.

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

If your mini-split is not heating or blowing hot air, frozen coils might be the issue. Like we talked about before, icy coils could be the consequence of low refrigerant, a faulty circuit board or malfunctioning sensors. Contact us at 601-736-7362 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 uses refrigerant to shift heat and keep your house comfortable. These leaks must be repaired by a licensed HVAC technician, so reach us at 601-736-7362 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this may be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s oversized will cool down a space too fast without having a moment 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 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 may have a mold issue. Have a specialist like Watts Electric & A/C Inc inspect and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably experiencing a refrigerant leak. Another surefire clue that you don’t have ample refrigerant is a weak flow of cold air. Call us at 601-736-7362 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, reach us at 601-736-7362 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 dead, your mini-split won’t run. In the majority of instances, putting in new batteries will solve the situation. If you’re still having trouble, contact us at 601-736-7362.
