7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort troubles in your residence. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into troubles from time to time. Here are seven of the most frequent mini-split issues 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 expected for a drain line to be clogged with mold, force water to back up and spill. Reach Central Air LLC at 203-357-5913 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re running. But there are a few times where they might create sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can happen if your mini-split turns on defrost mode to prevent itself from icing up.

You shouldn’t be alarmed if you hear these noises as they’re expected. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is off, such as not enough refrigerant, a flawed circuit board or broken sensors. Your Central Air LLC HVAC professional will be able to locate and solve the issue fast.

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 previously, iced-over coils may be the result of insufficient refrigerant, a bad circuit board or malfunctioning sensors. Contact us at 203-357-5913 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 uses refrigerant to transfer heat and keep your residence cool. These leaks must be resolved by a licensed HVAC pro, so reach us at 203-357-5913 for assistance.

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 too large will cool down a space too fast without having a chance 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 tell you 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 likely have a mold issue. Have a pro like Central Air LLC 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 possibly experiencing a refrigerant leak. Another surefire hint that you don’t have enough refrigerant is a weak flow of cold air. Call us at 203-357-5913 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Either way, reach us at 203-357-5913 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t turn on. In the majority of experiences, putting in new batteries will solve the problem. If you’re still having trouble, contact us at 203-357-5913.
