7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise way to solve comfort difficulties in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can run into problems sometimes. Here are seven of the most typical mini-split problems and how you can fix them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there could be an issue 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 spill. Contact Street Heating and Cooling at 605-206-3915 for help and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re operating. But there are a couple of 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 operating.
  • Swooshing, crackling or gurgling: This can occur if your mini-split goes into defrost mode to stop itself from freezing over.

You shouldn’t be worried if you hear these noises because they’re normal. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is off, including low refrigerant, a faulty circuit board or malfunctioning sensors. Your Street Heating and Cooling HVAC pro will be able to find and solve the problem quickly.

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

If your mini-split is not heating or blowing hot air, icy coils could be to blame. Like we discussed before, frozen coils may be the consequence of not enough refrigerant, a faulty circuit board or malfunctioning sensors. Contact us at 605-206-3915 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 relies on refrigerant to shift heat and keep your home pleasant. These leaks must be repaired by a licensed HVAC tech, so contact us at 605-206-3915 for help.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s oversized. A system that’s too big will cool down a room too rapidly without having a moment to dehumidify it. Mini-split size is calculated 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 likely have a mold issue. Have a specialist like Street Heating and Cooling 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 likely experiencing a refrigerant leak. Another surefire sign that you don’t have enough refrigerant is a low concentration of cool air. Call us at 605-206-3915 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Nevertheless, reach us at 605-206-3915 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are out of juice, your mini-split won’t run. In most instances, putting in fresh batteries will resolve the trouble. If you’re still running into trouble, reach us at 605-206-3915.
