7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort issues in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can have problems from time to time. 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 may 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 spill. Call Olde Towne Heating & Air at 843-485-0967 for help and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re on. But there are a couple of times where they may make sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can occur if your mini-split turns on defrost mode to stop itself from icing up.

You shouldn’t be troubled if you hear these noises because they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is off, including insufficient refrigerant, a faulty circuit board or broken sensors. Your Olde Towne Heating & Air HVAC tech will be able to locate 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 may be the consequence of low refrigerant, a failing circuit board or broken sensors. Call us at 843-485-0967 for help.

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 home pleasant. These leaks must be fixed by a licensed HVAC tech, so reach us at 843-485-0967 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 can be interrupted 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 too big will cool down a room too rapidly without having time to dehumidify it. Mini-split size is based 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 common 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 Olde Towne Heating & Air inspect and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another surefire clue that you don’t have enough refrigerant is a low concentration of cold air. Reach us at 843-485-0967 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Nevertheless, contact us at 843-485-0967 for assistance.

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 turn on. In the majority of situations, replacing the batteries will solve the problem. If you’re still experiencing trouble, contact us at 843-485-0967.
