7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort difficulties in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have problems occasionally. Here are seven of the most typical mini-split troubles and how you can repair 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 common for a drain line to be clogged with mold, force water to back up and leak. Contact Kohles & Bach Heating & Cooling at 515-207-6569 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re operating. But there are a few situations where they might produce sounds.

  • Popping or clicking: This can be because of 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 stop itself from icing over.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is wrong, such as insufficient refrigerant, a flawed circuit board or broken sensors. Your Kohles & Bach Heating & Cooling 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, ice on the coils may be to blame. Like we talked about prior to this, icy coils may be the consequence of insufficient refrigerant, a faulty circuit board or broken sensors. Call us at 515-207-6569 for assistance.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC needs refrigerant to move heat and keep your residence cold. These leaks must be resolved by a licensed HVAC pro, so contact us at 515-207-6569 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this might be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too large. A system that’s too big will cool down a space too quickly without having a chance 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 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 professional like Kohles & Bach Heating & Cooling examine and rinse the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another surefire sign that you don’t have sufficient refrigerant is a low concentration of chilled air. Call us at 515-207-6569 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Nevertheless, call us at 515-207-6569 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t run. In many instances, putting in fresh batteries will fix the issue. If you’re still having trouble, reach us at 515-207-6569.
