7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort troubles in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can experience problems occasionally. Here are seven of the most frequent mini-split problems 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 typical for a drain line to be clogged with mold, force water to back up and spill. Contact Air Concepts of Middle Georgia at 478-200-5689 for support and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. 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 stop itself from icing over.

You shouldn’t be worried if you hear these noises because they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is wrong, such as not enough refrigerant, a faulty circuit board or broken sensors. Your Air Concepts of Middle Georgia HVAC tech will be able to pinpoint and resolve the situation fast.

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

If your mini-split is not heating or blowing hot air, frozen coils could be to blame. Like we discussed before, icy coils can be the consequence of low refrigerant, a faulty circuit board or defective sensors. Reach us at 478-200-5689 for support.

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 relies on refrigerant to shift heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC pro, so call us at 478-200-5689 for support.

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 can be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too large. A system that’s oversized will cool down an area too fast without having a chance to dehumidify it. Mini-split size is planned 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 specialist like Air Concepts of Middle Georgia inspect and rinse the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another surefire hint that you don’t have ample refrigerant is a lack of chilled air. Reach us at 478-200-5689 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Either way, reach us at 478-200-5689 for help.

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 most situations, putting in new batteries will fix the trouble. If you’re still running into trouble, call us at 478-200-5689.
