7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort troubles in your residence. These systems don’t require ductwork to provide energy-efficient heating and cooling. Similar to any other home comfort system, they can have problems sometimes. Here are seven of the most typical 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 may 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. Reach Van Haaften Plumbing & Heating at 641-628-3621 for assistance and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re on. But there are two situations where they could make sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can take place if your mini-split switches into defrost mode to stop itself from icing over.

You shouldn’t be troubled if you hear these noises because they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is off, including not enough refrigerant, a bad circuit board or defective sensors. Your Van Haaften Plumbing & Heating HVAC pro will be able to pinpoint 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, frozen coils might be the issue. Like we mentioned prior to this, frozen coils may be the result of not enough refrigerant, a bad circuit board or defective sensors. Call us at 641-628-3621 for support.

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 relies on refrigerant to shift heat and keep your residence cool. These leaks must be fixed by a licensed HVAC pro, so contact us at 641-628-3621 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s too big. A system that’s oversized will cool down an area too quickly without having time 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 usual 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 Van Haaften Plumbing & Heating examine and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a weak flow of cool air. Call us at 641-628-3621 for help.

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. Regardless, reach us at 641-628-3621 for support.

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 many instances, replacing the batteries will fix the situation. If you’re still running into trouble, contact us at 641-628-3621.
