7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort issues 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 experience troubles from time to time. Here are seven of the most common mini-split troubles 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 expected for a drain line to be clogged with mold, force water to back up and leak. Call Rescue Heating & Air at 361-265-4371 for assistance and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re on. But there are two situations where they may produce sounds.

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

You shouldn’t be alarmed if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is off, including low refrigerant, a bad circuit board or broken sensors. Your Rescue Heating & Air HVAC professional will be able to pinpoint and resolve 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 might be to blame. Like we talked about previously, icy coils might be the consequence of not enough refrigerant, a failing circuit board or broken sensors. Call us at 361-265-4371 for support.

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 house cold. These leaks must be resolved by a licensed HVAC professional, so reach us at 361-265-4371 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be interrupted by clogs 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 too large will cool down an area 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 grab 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 likely have a mold issue. Have a pro like Rescue Heating & Air 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 dealing with a refrigerant leak. Another sure sign that you don’t have sufficient refrigerant is a weak flow of cold air. Reach us at 361-265-4371 for help.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Nevertheless, reach us at 361-265-4371 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 turn on. In many situations, putting in new batteries will fix the problem. If you’re still experiencing trouble, reach us at 361-265-4371.
