7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort troubles 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 experience issues occasionally. Here are seven of the most typical mini-split issues 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 might 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 drip. Call Oak Grove Heating & Air Conditioning at 601-292-9763 for assistance and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re on. But there are two times where they might make 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 take place if your mini-split turns on defrost mode to prevent itself from icing up.

You shouldn’t be troubled if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is wrong, such as insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your Oak Grove Heating & Air Conditioning HVAC tech will be able to pinpoint and resolve the issue quickly.

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

If your mini-split is not heating or blowing hot air, ice on the coils might be the issue. Like we mentioned previously, iced-over coils could be the consequence of insufficient refrigerant, a bad circuit board or malfunctioning sensors. Contact us at 601-292-9763 for help.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there may 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 professional, so contact us at 601-292-9763 for help.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too large. A system that’s too big will cool down a space too rapidly 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 get your attention 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 Oak Grove Heating & Air Conditioning 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 probably encountering a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a lack of cool air. Reach us at 601-292-9763 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Either way, reach us at 601-292-9763 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are out of juice, your mini-split won’t switch on. In many situations, replacing the batteries will solve the situation. If you’re still running into trouble, contact us at 601-292-9763.
