7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort troubles in your house. These systems don’t require ductwork to deliver 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 troubles 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 situation 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 spill. Reach Custom Air Systems Inc at 772-247-2283 for support and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re operating. But there are a few times where they could 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 happen if your mini-split turns on defrost mode to keep itself from icing over.

You shouldn’t be worried if you hear these noises as they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is up, including insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your Custom Air Systems Inc HVAC tech will be able to find and resolve the issue fast.

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 could be the issue. Like we talked about before, frozen coils could be the effect of low refrigerant, a faulty circuit board or malfunctioning sensors. Call us at 772-247-2283 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 move heat and keep your home cool. These leaks must be fixed by a licensed HVAC professional, so reach us at 772-247-2283 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 might be interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s too big will cool down an area too quickly 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 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 professional like Custom Air Systems Inc check and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another certain clue that you don’t have sufficient refrigerant is a low concentration of chilled air. Contact us at 772-247-2283 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Nevertheless, contact us at 772-247-2283 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 out of juice, your mini-split won’t switch on. In the majority of situations, putting in fresh batteries will solve the trouble. If you’re still running into trouble, reach us at 772-247-2283.
