7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a great approach to solve comfort issues in your residence. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can experience issues occasionally. Here are seven of the most frequent mini-split problems 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 might be a situation with the condensate drain or drain line. It’s common for a drain line to get clogged with mold, force water to back up and drip. Contact Colvin's Heating and Cooling at 816-379-3918 for assistance and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re running. But there are a few instances where they could make sounds.

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

You shouldn’t be alarmed if you hear these noises because they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is wrong, such as not enough refrigerant, a flawed circuit board or defective sensors. Your Colvin's Heating and Cooling HVAC technician will be able to find and solve the situation rapidly.

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 discussed prior to this, icy coils can be the effect of low refrigerant, a bad circuit board or broken sensors. Reach us at 816-379-3918 for support.

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 pleasant. These leaks must be repaired by a licensed HVAC professional, so contact us at 816-379-3918 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s oversized will cool down a room too quickly 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 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 professional like Colvin's Heating and Cooling inspect and flush the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another certain hint that you don’t have sufficient refrigerant is a low concentration of chilled air. Call us at 816-379-3918 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Nevertheless, call us at 816-379-3918 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t turn on. In the majority of situations, putting in fresh batteries will fix the problem. If you’re still running into trouble, reach us at 816-379-3918.
