7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort troubles in your house. These systems don’t require ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can experience troubles sometimes. Here are seven of the most typical mini-split troubles 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 an issue with the condensate drain or drain line. It’s common for a drain line to become clogged with mold, force water to back up and leak. Reach Smyth Air Conditioning Inc at 561-533-6066 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re operating. But there are two times where they could create sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can occur if your mini-split switches into defrost mode to stop itself from freezing over.

You shouldn’t be troubled if you hear these noises since they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is wrong, like not enough refrigerant, a flawed circuit board or defective sensors. Your Smyth Air Conditioning Inc HVAC professional will be able to find and resolve the problem 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 talked about previously, icy coils might be the consequence of insufficient refrigerant, a failing circuit board or defective sensors. Call us at 561-533-6066 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 needs refrigerant to transfer heat and keep your home cold. These leaks must be repaired by a licensed HVAC pro, so reach us at 561-533-6066 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s oversized. A system that’s oversized will cool down an area 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 grab 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 could have a mold issue. Have a specialist like Smyth Air Conditioning Inc check 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 likely experiencing a refrigerant leak. Another sure clue that you don’t have enough refrigerant is a weak flow of cool air. Contact us at 561-533-6066 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Nevertheless, reach us at 561-533-6066 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t run. In most instances, putting in new batteries will fix the problem. If you’re still experiencing trouble, reach us at 561-533-6066 .
