7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort problems in your house. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can run into issues from time to time. Here are seven of the most common mini-split issues and how you can solve 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 become clogged with mold, force water to back up and spill. Call Anderson Heating & A/C at 775-230-7628 for support and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re running. But there are a few instances where they might create 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 take place if your mini-split turns on defrost mode to prevent itself from freezing over.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, including low refrigerant, a faulty circuit board or malfunctioning sensors. Your Anderson Heating & A/C HVAC tech will be able to locate and resolve the issue 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 the problem. Like we talked about before, frozen coils may be the effect of insufficient refrigerant, a faulty circuit board or broken sensors. Call us at 775-230-7628 for assistance.

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 needs refrigerant to move heat and keep your home cold. These leaks must be fixed by a licensed HVAC tech, so reach us at 775-230-7628 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this may be stopped by blockages 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 too big will cool down a room too quickly 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 typical 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 pro like Anderson Heating & A/C examine and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another surefire hint that you don’t have ample refrigerant is a weak flow of cool air. Contact us at 775-230-7628 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Nevertheless, call us at 775-230-7628 for help.

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 many situations, replacing the batteries will resolve the problem. If you’re still running into trouble, reach us at 775-230-7628.
