7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort problems in your house. 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 troubles sometimes. Here are seven of the most frequent mini-split problems and how you can repair 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 common for a drain line to be clogged with mold, force water to back up and spill. Reach Uptown Heating & Cooling at 614-344-6949 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 running. But there are two times where they may 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 keep itself from icing up.

You shouldn’t be worried if you hear these noises since they’re expected. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is off, such as insufficient refrigerant, a faulty circuit board or defective sensors. Your Uptown Heating & Cooling HVAC technician will be able to find and solve the situation quickly.

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, frozen coils can be the effect of insufficient refrigerant, a bad circuit board or defective sensors. Contact us at 614-344-6949 for assistance.

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 move heat and keep your home pleasant. These leaks must be fixed by a licensed HVAC technician, so contact us at 614-344-6949 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be stopped 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 large. A system that’s oversized will cool down a room too fast without having a chance 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 get your attention that something is wrong. Here are five of the most usual 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 specialist like Uptown Heating & Cooling check 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 surefire hint that you don’t have enough refrigerant is a low concentration of chilled air. Call us at 614-344-6949 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Nevertheless, contact us at 614-344-6949 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 turn on. In the majority of instances, replacing the batteries will fix the trouble. If you’re still having trouble, reach us at 614-344-6949.
